Winter weather is with us through tonight, as temperatures remain quite cool. The good news? Some early spring-like weather is just around the corner, as temperatures will moderate and warm quite a bit on Sunday.
Mid-level height rises and deep southwest flow on Sunday, will help temperatures rise into at least middle to upper 50s with plenty of sunshine. It’s not out the question that some locations, particularly over Central New Jersey, will reach 60 degrees tomorrow afternoon. The southwest winds off the ocean or sound could keep temperatures cooler for parts of Long Island and Connecticut.
A large deep low, which has been producing some severe weather and tornadoes over parts of Deep South over past few days, will be heading northward into Eastern Ohio Valley today. This storm will send a cold front northward through the Mid-Atlantic region this afternoon and evening.
Ahead of this front, positive vorticity advection, strong jet streak forcing and instability will be increasing. A convective or forced squall line is likely to develop over Central Pennsylvania southward into Virgina, with torrential downpours and gusty winds near the low. Further south there is potential for more severe weather and tornadoes with greater instability. The Storm Prediction Center has issued large area of enhanced and moderate risks for parts of Virgina North Carolina, with slight and marginal risks further up and down the East Coast.
