SYNOPSIS. Low pressure will move through mid week, with high pressure building in late in the week through next weekend.

NEAR TERM /Through Today/. As of 4 AM Tue . Sfc cold front has passed offshore of ENC early this morning. High 850 mb RHs trapped under the frontal inversion spell mainly overcast conditions will continue through today. A couple showers or sprinkles possible today, but most places remain dry, and not expecting anything more than a T of rain in the spotty showers. Temps seasonably mild with highs 65-70.

SHORT TERM /Tonight/. As of 4 AM Tue . Low pressure will develop in the Deep South along low level wavy front to our south overnight. Isentropic lift strengthens late tonight, with light rain possibly overspreading the swrn zones just prior to sunrise. Low temps seasonably cool with readings in the low/mid 50s.

LONG TERM /WEDNESDAY THROUGH MONDAY/. As of 315 AM Tuesday . Strong signal continues in the model guidance of a late-season cold air damming event Wednesday as parent high pressure builds east and south from the Ohio Valley and wedges down the East Coast. Continued trends of previous forecast adjustments with high temperatures below the lowest guidance for Wednesday, in the mid/upper 50s area-wide. Strong isentropic lift over the wedge will lead to steady stratiform precipitation, particular over the southern half of the CWA and have raised PoPs to high likely/categorical over the southern tier and high chance north for Wednesday.

Weak waves of low pressure moving south of the area will keep small rain chances in the forecast for Thursday into Friday, while temperatures remain below normal with chilly lows in the mid to upper 40s, and highs upper 60s to lower 70s Thursday and Friday.

High pressure building along the eastern seaboard will lead to a slow warming trend under generally clear skies. Temperatures will edge back toward 80 degrees for the weekend and into the lower 80s by early next week. An approaching cold front may bring in some scattered showers and thunderstorms by Tuesday.
