We are going into Storm mode today through Thursday. 2 significant storm systems will impact the area, one will be a snow/ice event tomorrow the next will be a major wind/rainstorm Wednesday into Thursday with the potential for strong thunderstorms .
For today and most of tonight skies will remain clear , highs today in the mid 20s to low 30s and lows tonight in the mid teens to low 20s area wide
A warm front is currently developing over the Midwest with icy precipitation breaking out, this will move east and begin to impact the area tomorrow morning, likely between 6-9 am from west to east . The stubborn arctic air in place with warm air over-riding is the driving force , along with cold air damming along and east of the Appalachians
The precipitation along the coast will be light and scattered in nature due to high pressure to the northeast keeping dry air in place , inland areas will see a more organized area of precipitation , but all area will start off as snow , quickly go to sleet except for NE PA , over to freezing rain besides the coast where you will transition from sleet right to light rain.
Light pink – C-1 inch of snow and sleet over to light rain
Medium pink – C-2 inches of snow and sleet to freezing rain a coating of ice (up to 0.05) over to light rain
Dark pink – 1-3 inches of snow and sleet to freezing rain 0.05-0.10 of ice , light rain to end

The warm front will move north of all areas Monday night into Tuesday AM leading to much warmer air bein transported into the region with cloudy skies a chance of showers and highs in the low 40s NE PA to upper 40s along the coast
Wednesday a strong area of low pressure will form over the southern Plains with a amplified trough coming east and a intense clash of warm/cold air , it will track through the Great Lakes , the associated cold front will come through Wednesday afternoon through Thursday morning with heavy rain, a lot of wind and the potential for yes, thunderstorms , some of which could be strong. Ahead of the front will come a strong push of warm air with highs in the upper 40s NE PA to mid to upper 50s along the coast
We see with this storm system a very strong jet streak will come through , winds with this are expected to be out of the south at 20-30 MPH with gusts potentially hitting 60+ mph in thunderstorms and exceeding 50 in periods of heavy rain , a general 1.5-2.5 inches of rain is expected, localized flooding is possible along with damaging wind gusts.
