<title><![CDATA[It's Amazing What We Now Can See]]></title>
<description><![CDATA[Modern technology is allowing us to see things that people 50 years ago never imagined that we can see. Here is a great link: http://nnvl.noaa.gov/MediaDetail.php?MediaID=75&amp;MediaTypeID=2 It is a visualization of the entire 2008 hurricane season. It really highlights the activity of a season. Most notable is peak activity that occurs in September and Ike&#39;s trek along the tropics. Also, you can see the strengthening jet stream and how the switch is made heading into autumn. ]]></description>

<title><![CDATA[Very Dry, Mild November Follows a Wet, Cold October ]]></title>
<description><![CDATA[The raindrops finally have started falling today, which will go down as
the first significant rainfall for most places in a few weeks.&nbsp; Up
through yesterday, there had been no measurable rain in Altoona since
last month, an impressive feat but not quite record-breaking.&nbsp; The
longest November dry streak on record is 21 days, which happened back
in 2001.&nbsp; I can hear the rain pounding on our roof, and I wouldn&#39;t be
surprised at all if we saw a half inch of rain or even an inch by day&#39;s
end.

It&#39;s been a truly remarkable change that has happened over the past
month and a half.&nbsp; Throughout the month of October, all we seemed to
talk about was how wet and cool it was.&nbsp; We wound up with over 6&quot; of
precipitation for the month of October, with some places seeing even
more than that.&nbsp; That is well above average, as October tends to be one
of our drier months.&nbsp; What October 2009 will be famous for is one of
the coldest stretches ever for the month, as highs for several days
only got into the 30s.&nbsp; The month as a whole turned out to be cooler
than average, thanks mostly to the above average precipitation.&nbsp; Why?&nbsp;
Because when we see a lot of precipitation, the ground has more
moisture in it.&nbsp; When the ground has more moisture, some of the sun&#39;s
energy has to go towards evaporating the moisture instead of just
heating the ground.

Then the calendar changed into November and the rain shut off.&nbsp; And,
with less rain, there is less moisture in the ground.&nbsp; So, with much
less moisture in the ground, more and more of the sun&#39;s rays go towards
heating the ground.&nbsp; The result is a climate somewhat similar to a
desert.&nbsp; When the sky is clear, the temperatures can be dramatically
different from morning to afternoon because the sunshine can warm the
ground very effeciently, while the lack of clouds at night allow all of
the heat absorbed by the ground during the day to radiate back into
space.&nbsp; Some of our nicest weather has been on the weekends, and that&#39;s
where those big temperature spreads have been.&nbsp; A few examples from
Altoona this month:

Saturday 11/7 -- High 60, Low 26&nbsp; (Spread = 34) 
Sunday 11/8 -- High 70, Low 39&nbsp; (Spread = 31)
Sunday 11/15 -- High 68, Low 37&nbsp; (Spread = 31)

These certainly aren&#39;t record spreads, but they are very impressive for
the month of November.&nbsp; Remember, we&#39;re only a month away from the
winter solstice and we&#39;ve only been seeing about 10 hours of daylight
each day.&nbsp; With that limited amount of sun, conditions really need to
be set up perfectly to get temperatures to rise that much during the
day after such a chilly morning. &nbsp;

Those days in the 60s and 70s may be behind us, though.&nbsp; Our computer
models continue to indicate that much colder air will start to move
back into the area by the end of next week, making Thanksgiving and the
following weekend feel much more like late November.

<title><![CDATA[Things Missing This November]]></title>
<description><![CDATA[&nbsp;There are three things that have been missing this November, weather speaking of course. I know as you read this, you are sitting there saying, yeah, we&#39;re missing that November chill. And you are correct. And if you have been watching me, you probably already know about the second thing missing, and that is rain. It has been the driest start to November that I have ever seen. Places like Altoona have made it through the first 17 days without measurable rainfall. It makes for our longest November dry streak since 21 days in 2001. So what is the third thing missing? Have you figure it out yet? Once I say it, you are going to agree. It&#39;s the one that is also quite impressive for me. Okay, I guess I have stalled long enough to spill the beans. Wind. That brisk November wind has been lacking. Sure there has been a breeze on a couple of days, but the lack of strong cold fronts has caused a lack of days with strong winds. Temperature and pressure are linked which means temperature and winds are linked too. Therefore, the lack of any strong cold spells has slackened our winds for the month. &nbsp;I do expect the end of all three streaks within the next week to ten days. We&#39;ll have some rain showers Thursday and I expect a cold snap and some winds later Thanksgiving week. ]]></description>

<title><![CDATA[Leonid Meteor Shower Peaks in the Next Day]]></title>
<description><![CDATA[Every November, the Earth passes through a trail of dust left behind the comet Temple-Tuttle. Most of these particles are much smaller than a grain of sand, but the friction with the air of the atmosphere allows for them to heat tremendously. This heat creates the bright light of meteors, or shooting stars. This year, the show should be pretty good with an average peak of around 100 per hour expected early Tuesday morning. This means that you may see just over one per minute. Some high clouds will interfere with the show a bit.]]></description>

<title><![CDATA[Don't Give Ida All of the Credit.]]></title>
<description><![CDATA[There has been a lot of devastation along the coast of Virginia, Maryland and New Jersey with coastal flooding and wind gusts approaching hurricane strength. The total damage may reach over a billion dollars and news reporters have flocked to the scenes to help show the damage. Since this system started as a tropical system, and was Tropical Storm Ida when it moved onshore in the southeast, the name has stuck. And the flooding rains from Mississippi to Virginia were directly related to this tropical system. Though the coastal flooding, the high winds, and the damage total would not be the same if it were from Ida alone. The fierce winds are a result in the pressure difference between that low and an area of high pressure to the north. The battle of this system has raged for a couple of days as they have been stubborn to move, but the high will shift to the east and things will start to calm over the weekend. And that is good news. ]]></description>

<description><![CDATA[Many of you were pleasantly surprised over the past couple of days as we were treated to what was perhaps a final round of Indian Summer.&nbsp; We even approached record highs on Sunday and Monday, missing it by 2 degrees on Sunday and 4 on Monday.&nbsp; When we&#39;re that close to record temperatures, it means that several things are coming together to make it that warm or cold.]]></description>

<title><![CDATA[The Darkest Time of the Year]]></title>
<description><![CDATA[No, I am not being philosophical or making any bad commentary about the
colder time of the year that is coming our way. What I am referring to
is the start of Solar Winter which started today and will then last
until the beginning of February. This marks the quarter of the winter
upon which the sun heats the northern hemisphere the least. It all
stems to the tilted axis of the Earth. As the Earth revolves around the
sun, there are times that the northern hemisphere is tilted toward the
sun. This creates a higher sun angle and allows the sun to better heat
the ground. It also marks the time of the year where the daylight hours
are at a maximum. There are also times when the northern hemisphere is
tilted away from the sun, creating a low sun angle, and even no sun for
the polar regions. This is our solar winter. During this time, the sun
is less effect and at a lower angle and the nights are long. It marks
the period when our half of the Earth loses more energy than we gain
and leads to a deepening cold. This is the true reason for the seasons.


Solar winter does not match up with the weather though as we do still
have winter weather after the end of solar winter in early February.&nbsp;
Though if you notice, things really do start to get brighter again
during February and our average temperatures start to rise. A response
to that good old sun.

<description><![CDATA[One reason to have a blog is to spout opinions, so I&#39;m going to complain about Daylight Saving Time tonight.&nbsp; It seems stupid to do it tonight since we are actually gaining an hour this weekend, which makes it officially the longest weekend of the year, but I&#39;m going to do it anyway.]]></description>

<title><![CDATA[Closing Out October Snow-Free]]></title>
<description><![CDATA[It&#39;s pretty typical during the autumn months that we have spells where it&#39;s unusually warm and unusually cool.&nbsp; That&#39;s how it will be this again this week, although we are not looking at any big cool snaps over the next seven days.&nbsp; It appears that the snow we picked up last week on the 15th and 16th could be the only flakes we see this October, as any air mass cold enough to produce snow will not arrive until after the month ends this coming Saturday.]]></description>

<title><![CDATA[Going Into the Hall of Fame]]></title>
<description><![CDATA[



Being a meteorologist and studying the weather for a long
period of time, there have been certain weather events that stand out as extraordinarily
impressive. In my mind, I have sort of a hall of fame of such for Central Pennsylvania. This weather pattern is definitely
going into my top five. 

&nbsp;

And no, I&rsquo;m not talking about the snow. While it has been
visually impressive to many, a darling to the media, and unfortunately, a
disaster to some who lost trees and power, it has only been a symptom to what I
am calling the impressive weather event. And that event is the strength of the
cold of this mid-October air mass. We are breaking, if not smashing, three or
four day&rsquo;s worth of record low high temperatures. I know that record is hard to
swallow at first glance, but an example that I am talking about is that our
high temperature in Altoona
was only 35 degrees. The previous lowest high temperature we had for the date
was 48 degrees. Breaking a record by such an amount says a lot to the
situation. We also set new records for Thursday and will likely for Saturday
and Sunday. 

&nbsp;

So what brought this hall of famer cold snap? Well it was a
perfect combination of just the right things. We had a series of snow events
that briefly brought snow covers to a good portion of Central Canada and the
Northern Plains of the United
  States. After that happened, a trough in the
jet stream ushered in an impressive polar air mass into the Midwest
and the Northeast. This is not unusual for the time of the year. But since that
snow cover was in place, the air mass did not modify as much as it normally
would. Hence a set up of a cold pattern. Throw in a few disturbances that fed
off of the contrast in temperatures from this cold air and the warmth to the
south, and their favorable track to our south, and voila, what we have is the
resultant pattern. 

&nbsp;

It&rsquo;s not the extreme of cold that really makes this
memorable, but the departure from the average that is impressive. We&rsquo;re missing
the cold nights from the cloud cover, but most humans perceive chilliness
during the day anyway.

&nbsp;

Why not the snow on it&rsquo;s own? Well again, it was a symptom
to the big overall pattern. Besides, our memories are short and we always felt
what we experienced was the worst, but even the worst hit areas don&rsquo;t hold a
candle to the biggest warm season snow for the region. That was in 1928. There
was over 2 feet of snow in a period of 3 days when leaves were on trees. And I&rsquo;m
talking the valleys, I have yet to see what fell on the ridges. That is number
one on my list, period. The more recent number one for cold is December of
1989. We spent almost an entire month below freezing and that is not easy for
December. &nbsp;And once again, I&rsquo;m talking
the valleys. 

&nbsp;

<title><![CDATA[Frost Versus a Freeze]]></title>
<description><![CDATA[I have a lot of people always ask me what the difference is. A frost occurs when the temperature of a surface drops to the dew point which is below freezing. At this point, we get deposition of ice crystals on these surfaces. Since the cooling always starts with objects on the ground, it is common to get frost when the official low temperature is above the freezing mark. A freeze is more damaging to plants. This occurs when the air temperature drops below freezing and objects on the ground get below freezing for a period of time. This causes water to freeze in parts of a plant and can cause the end of that plants growing season or life.]]></description>

<title><![CDATA[The Strong October Winds Will Be Blowing]]></title>
<description><![CDATA[October is widely known for colder nights, shorter days, the first frost and snowflakes. But it is also a month where the winds start to blow more. The reason has to do with the contrast with the increasing cold in the northern latitudes and the lingering warmth to the south. Wednesday will be one of these blustery days. A cold front will pass through in the morning and we will have some gusts of wind over 40mph with and behind it. Eventually, a ridge of high pressure will build over the region and subside the winds by Thursday, but more winds are likely before and after another front which will cross later Friday.]]></description>

<title><![CDATA[If it's still summer, then why has it been so cool?]]></title>
<description><![CDATA[That's a question that I have been getting in some version or another for the past couple of weeks. And I've been telling all of the people the same thing; It's that time of the year. That's right. Meteorologically speaking we are in Autumn and have been for a couple of weeks. Mother Nature doesn't agree with what you see on the calendar. Those season markings have more to do with the position of the sun rather than the weather. Though by the beginning of September the balance of energy for the Northern Hemisphere has switched. We are now losing more energy than gaining and air masses are getting cooler, especially in the high latitudes. This causes our average temperatures to start to fall; pun intended.]]></description>

<title><![CDATA[The Hurricane in the Middle of Nowhere]]></title>
<description><![CDATA[You may have heard in passing that Hurricane Fred formed in the far Eastern Atlantic back on Monday.&nbsp; The storm is not far from the west coast of Africa and is going to meander around out there for the next few days while weakening in cooler waters.&nbsp; Fred did become a major hurricane briefly on Wednesday, and became one of the few storms to become a major hurricane that far to the east.&nbsp; A fierce storm, but no one really is affected by it.&nbsp; It kind of brings back the old saying that if a tree fell in the forest and no one was there to hear it, did it make a sound at all?It was only a few years ago, back in 2005, that we had a record breaking year of tropical activity in the Atlantic, with 27 named storms.&nbsp; This was highly publicized as smashing the record of 21 storms set back in 1933.&nbsp; However, this number is not necessarily true.&nbsp; Satellites were not launched until the 1960s, which now allow us to scan the Atlantic and oceans around the world for storms.&nbsp; There may have been other storms this year, but they formed in the middle of the ocean and a ship didn&#39;t happen to cross its path.&nbsp; So, even though hurricane records date back to the 1800s, chances are we missed dozens of storms that would have been considered tropical storms and hurricanes by today&#39;s standards.&nbsp; Why?&nbsp; Simply because we couldn&#39;t see them.The question is, if the year was say, 1925 instead of 2009, would we ever have known that Category 3 Fred was churning up the Atlantic waters?]]></description>

<title><![CDATA[More Tropical Trouble: Erika]]></title>
<description><![CDATA[The official peak of the Atlantic Hurricane Season is next week, so it is no surprise that we are tracking a new tropical storm.&nbsp; Tropical Storm Erika became the 5th named storm of the 2009 Atlantic Hurricane Season on Tuesday.&nbsp; It is moving through the Leeward Islands today and will pass very close to Puerto Rico by Thursday or Friday.&nbsp; It is a slow moving system, so any effects on the U.S. are likely 5 to 7 days away.This is a storm that will need to be watched very closely.&nbsp; First, the water out ahead is very warm, a key ingredient for hurricane development.&nbsp; Also, unlike Bill and Danny from earlier this season, there will be no big trough coming into the Eastern U.S.&nbsp; This would allow Erika to move farther west than either of those storms and pose a greater threat to the East Coast.&nbsp; At this point, any threat from Erika to the U.S. is 5 to 7 days away, but it is something that will need to be watched very closely.]]></description>

<title><![CDATA[Maine Tragedy Teaches Us A Lesson]]></title>
<description><![CDATA[Despite remaining hundreds of miles away and never making landfall on the U.S. coast, Hurricane Bill claimed the life of a seven-year-old girl at Acadia National Park along the Maine coastline. This tragedy should drive home an important point, and that is to always take hurricanes seriously, even if they are a couple hundred miles away.&nbsp; Hurricanes can produce heavy surf from many hundreds of miles away, sometimes a couple of days before it hits land.Bill was only a Category 1 hurricane with top winds of around 85 MPH.&nbsp; However, these damaging winds never made it to Acadia, and the highest wind gusts were only between 25 and 30 MPH, which is equivalent to a normal windy day here in Central PA.&nbsp; So while the wind may not have indicated a danger, the visitors to Thunder Hole at the park should have heeded the many warnings and beach closures due to the heavy surf and stayed away from the water.&nbsp; Storm surge, which is measured by how much the waves increase due to a storm, is arguably the most dangerous part of a hurricane.&nbsp; More people are killed by the storm surge and increased surf than from anything else.&nbsp; Why is that?&nbsp; Perhaps it&#39;s because dangerous waves associated with hurricanes can occur when the weather may be sunny and calm.&nbsp; And while the waves may not look that high, the rip current becomes more powerful, which can drag even a strong swimmer well away from the beach.This story caught my eye more than usual because I&#39;m planning on making a stop in Acadia next month.&nbsp; As someone who always enjoys seeing the power of nature, I wouldn&#39;t mind seeing some towering waves when I&#39;m there.&nbsp; That being said, I would not go that close to the water if the waves were that high.]]></description>

<title><![CDATA[Hurricane Bill Should Miss U.S.]]></title>
<description><![CDATA[Hurricane Bill is making the headlines as the storm is the not only the season&#39;s first hurricane, but the season&#39;s first major hurricane.&nbsp; As of 5:00am this morning, Bill was a Category 4 hurricane with top winds of 135 MPH.&nbsp;&nbsp; There is the potential for Bill to become a Category 5 storm before the end of the week is out.&nbsp; The big question is, where does this powerful storm go from here?&nbsp; A trough moving east out of the Midwest should help steer Bill out to sea.&nbsp; However, if the trough lags behind at all, the storm could track farther to the west.&nbsp; It could come far enough west to clip parts of Cape Cod and Maine with some rain and wind late this weekend. Bill should have no major impact on our weather as it should be hundreds of miles away.&nbsp; However, if Bill is strong enough to hold up the trough moving in from the Midwest, the cooler weather we have been forecasting to begin on Saturday may get held up for one day and not fully arrive until Sunday.]]></description>

<title><![CDATA[We Are Now in Fog Season]]></title>
<description><![CDATA[If you are an early riser, you likely have noticed an increase in foggy mornings. It is a very common thing this time of the year as the late summer through mid autumn is the heart of fog season. The reasons why are pretty simple but first let me refresh in what forms fog. For this purpose, I'll talk about radiation or valley fog, which is the most common during this time of the year. All cooling and heating starts with the ground. When the sun goes down, the ground emits more energy than is gained, and it cools. If the ground surfaces cool to the dew point temperature, then we have the formation of dew. If the cooling persists, then the air above the ground will then cool to the dew point and condensation will help to form fog. On clear, calm nights, we get the maximum cooling along the ground. Since the cool air tends to collect in the lowest spots, the fog is often densest in the valley locations. Once the sun rises, the ground is the first to warm. The temperature and dew point at the ground depart and that allows the fog to evaporate. This is why fog vanishes from the ground upward.

  Now that we understand the formation of fog, we can address why this is the foggier time of the year. The nights are growing longer which allows for the ground to cool more each night. On top of that, the dew point temperatures are still high from the warm season with maximum evaporation of surface water. The combination of these two allow for the temperature and dew point to meet, giving us fog.]]></description>
