Tuesday Midday

Synopsis:  A warm front is pushing through the state this morning.  Western PA as of 10am is already in the upper 40's to around 50, while Eastern PA is in the 30's.  Warm air advection will occur today and tomorrow before a cold front loses its strength as it crosses the state.  A potential storm will try to take aim at us for Thursday, but will be suppressed to the south.  Places south of the Turnpike might see a sprinkle or two on Thursday.  A brief cool down for the rest of the week will occur as high pressure moves through the region. 


Short-term:  A warm front moves through the state by noon today, warm air advection will occur for the rest of the day, and into Wednesday ahead of a cold front that seems to lose strength as it moves across the state.  This means scattered showers in the morning and early afternoon for the state, with clearing conditions.


Long-term:  The models have been inconsistent from Thursday to the end of the weekend, so the forecast could change.  Right now the models try to have a storm like 2 weeks ago make a run at us, problem is it will be short of the goal line for Thursday.  We cannot rule out a chance of a sprinkle on Thursday for anyone south of the PA Turnpike.  Everyone else should be partly sunny for the day.  For the past week, the models have tried to bring another storm up for the weekend, this time a snowier one.  The models have once again been inconsistent with having a storm moving through.  So at this time, the period from Friday-Saturday we are going with a no-storm approach until the models resolve their issues.  High pressure is in charge for Friday and Saturday continuing our brief winter blast (not really blast, with temps projected to be above 32F).


Kept temperatures near previous shift, with minor changes.
