A Mild Monday, But Then It's Into The Icebox !

The next seven days ahead
The next seven days ahead

Sunday was all about location, location, location; if you were north of Philly it was cloudy with even some snow showers throughout the morning and then there was sunshine by the afternoon. If you were south of Philly it was a great sunrise with some clouds by midday, but then they pushed north and there was sunshine leading to a great sunset. Now officially at Philly International we reached a high of 42 set at 3:43pm after a low of 21 set at 3:07am. The average high is 40 and the average low is 25 so the day was pretty much your normal Winter day.

Overnight skies will be mostly clear, but cold with lows in the middle and upper 20s; adding in a westerly wind between 10-15mph it will make it feel more like the lower and middle teens!

For your Monday(which is Martin Luther King, Jr. Day) it will start off sunny, but then by noontime we'll have clouds roll in. As temperatures climb toward the middle 40s this will ensure that anything falling will be rain(except well north and west in higher elevations where there will be a snow/sleet/rain mix). Overnight into early Tuesday morning a cold front ushers in colder air we will see a changeover to snow and also cause anything that's wet to freeze(and hence, ice). Temperatures at Midnight will be in the upper 30s, but tumble throughout the day.

Tuesday evening another clipper pushes through, but this one may be interesting as it dives south across the Delmarva, but a new low forms offshore; this could POTENTIALLY lead to some snowfall EAST of Philly overnight into Wednesday morning....but that's just from today's midday operational and ensemble runs. It is NOT etched in stone yet!

On Wednesday we'll finally get some sunshine! The catch is that we'll start the morning very cold into the middle teens, and we'll only warm up a few degrees into the lower 20s. The Arctic blast seems short lived as by Thursday we warm back above freezing with sunshine giving way to clouds in the afternoon in advance of another clipper working through.

We'll flirt with the freezing mark on Thursday with another clipper coming through overnight into Friday providing some snow showers; not much accumulation is expected, but behind it temperatures will drop by the early morning from around 30 to the lower 20s by sunset.
