Still Chilly

An ideal radiational cooling setup has allowed the temperature to drop to 18 already this morning. Today will be a transition day as our upper air flow becomes less amplified as the Eastern U.S. trough moves to the east. A warm air advection regime will begin aloft as this trough shifts eastward, but the lingering arctic air mass at the surface will be prevalent enough to put a damper on a big temperature increase. A surface high pressure that is just to our south will move to the east and will allow southerly winds to develop, but they will have to contend with the residual arctic air. Still, I think we can manage to hit 46 this afternoon under sunny skies.

Tomorrow morning's temperature is a little tricky. Southerly winds will increase moisture through the day and this evening, but clear skies and light winds will still allow for cold temperatures tomorrow morning. With this in mind, I'll forecast 27 tomorrow morning. Temperatures soar tomorrow with 60s possible and likely by Friday as another cold front approaches.
