Thunderstorms Possible this Afternoon

A strong cold front will push through the region this afternoon bringing with it a temperature change and some thunderstorms.  Temperatures will return to the upper 30's/low 40's during the middle of the week but will warm back into the 50's by the end of the week.  Some real nice spring days are on tap for next week.

Current Conditions/Observations
Here is the radar
NWS Northeast Regional Radar
Much of last nights rain has moved away.  There is trailing precipitation in Western NY, Central PA, and Eastern NC.  Here is the surface chart
WPC Surface analysis 330 am
This morning's rain is associated with the first cold front and low pressure traveling along it.  This afternoon will be driven by the trailing cold front.  Here are the current temperatures

Short Term Forecast
Temperatures are going to approach 60 before the FROPA (frontal passage).    Skies will be partly sunny this morning but clouds will build back in early this afternoon.  Max temperatures today

From the NAM hi-resolution model here is the projected radar image at 4 PM

Temperatures will drop like a rock following these thunderstorms. The WPC is not impressed with these storms so they are low on rainfall today.
WPC Day 1 precipitation 
Where the storms set up and crank will be where the heaviest rain falls.  There could be some small hail with these storms but the main threat will be a brief shot at 35-50 mph winds between 2 PM and 7 PM.

 By tomorrow morning we are looking at lows in the mid 20's

Tomorrow is clear, but windy and cold.  Each day through the rest of the week will get progressively warmer  so the 40's won't last long.  65-70 by the middle to end of next week is not out of the question.  The rumors of spring are true.
