A Winter Weather Advisory is in effect from 7 p.m. this evening to 11 a.m. Wednesday for the vast majority of our viewing area. We will see periods of snow and sleet during the overnight hours and into Wednesday morning. Snow accumulations will be 2-4" for many communities with 4-6" possible in portions of the Laurel Highlands and Northern Alleghenies.
This system will push through during the overnight hours and will have moved on by Wednesday afternoon/evening. The sky will clear somewhat Wednesday night, but the pattern is changing going into Thursday as another disturbance will push in from the northwest. This system will bring more flurries and temperatures in the low to mid 30s.
This weather pattern will send a series of disturbances at Pennsylvania from Canada and with it colder air. That pattern will be the big influence on temperatures Friday even as an area of high pressure moves in from the south. Some light snow could be seen in north of I-80 and high temps in the upper 20s and low 30s.
