WEATHER BLOG: Snow Showers

A cold front is still pushing eastward across western and central parts of Pennsylvania and New York State as of this writing... A 'clipper'-type wave in southeastern Ontario will be pulling this front though areas east of the Appalachians later, and it should trigger a couple of scattered snow showers... While we can't totally rule out the possibility of a ten or fifteen minute 'burst of snow', or heavy squall in some places -- especially in the higher terrain located north and west of the big cities, the longer-lasting impacts which will occur along the Eastern Seaboard today will include both increasing winds and dry conditions. Temperatures will peak in the upper 30s and lower 40s during midday or early this afternoon before it starts to turn noticeably colder later this afternoon and tonight.

We have had some convective snow showers move through the area already. We will have another batch come through. These snow showers currently to our west have produced a burst of snow from Cumberland to Hagerstown, reducing the visibility to 1/4 to 1/2 of a mile. And something could linger until about 1 PM. Then the trough axis triggering the snow showers will move east. As this happens we will dry out, but turn windy. In fact, wind gusts to 40 mph are expected this afternoon. No big changes to the long range. Guidance is coming in much cooler on Tuesday, so we will trim a couple of degrees off of the high.

Clearing should occur tonight, especially in areas east of the mountains... Along the coastal plain, a northwest wind will be strong enough to break up any leftover clouds -- and then this wind will diminish after midnight... Lows tonight will be in the teens or even the upper single digits in the coldest rural locations.
