SYNOPSIS. An extended period of dry weather is expected in central PA through early next week. Temperatures will bounce higher into Wednesday before cooling down through into the weekend. A more pronounced warming trend is projected to begin next week with odds increasingly tilted toward above average temperatures into mid March.
NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/. Full sunshine as of 1800 UTC across CPA with a cool but pleasant rest of the afternoon. Max temps 5-10F below daily climo. Clear and not as cold tonight especially over the western and northern mtns where a tightening p-gradient will sustain a west- southwest breeze and effectively put a floor under low temps in the 25-30F range. The coldest readings are likely to be found over the south central to southeast valleys where the boundary layer can decouple which should allow temps to bottom out closer to sfc dewpts or around 20F.
SHORT TERM /6 AM WEDNESDAY MORNING THROUGH 6 PM WEDNESDAY/. A weakening Alberta clipper sfc low streaking eastward across the Saint Lawrence River Valley early Wed. will send a moisture starved cold front southward across the lower Great Lakes into CPA by tomorrow evening. The only sensible wx from this dry front will be an uptick in the westerly breeze (common with dry fronts) and increasing low clouds sinking southward from NY into the northwest 1/2 of the CWA by 00Z Thu.
Max temps will bounce off the weekly lows on Tuesday and climb 10 to 20 degrees warmer, reaching the 50 degree mark across much of south central PA (east of the mtns). We were keen to stay on the warm-side of NBM across the southern 2/3rds of the CWA given more sunshine and downslope flow/low level mixing.
LONG TERM /WEDNESDAY NIGHT THROUGH TUESDAY/. A cold front crossing through the NE US will bring colder temperatures by Thu, with highs back in the 30s to low 40s. Northwest flow across the Glakes will bring a slight chance of LES to the typical areas of the NW on Thu. Chilly air will continue to flow into the area through the upcoming weekend as a large upper trough remains over SE Canada.
As the upper trough moves offshore by early next week and high pressure behind it moves into a Bermuda high position, warmer temperatures will move in to start the second full week in March. Long range guidance from CPC shows warmer temps likely lingering into at least the middle of March.
AVIATION /21Z TUESDAY THROUGH SUNDAY/. Widespread VFR through tonight with winds shifting to the west- southeast or to 230-260 degrees. 35-45kt LLWS fcst over the northern 1/2 of the airspace late tonight into early AM Wed. MVFR to low VFR cigs are likely to return to the northwest 1/2 of the airspace by 00Z Thu.
Outlook .
Thu-Fri . MVFR cigs psbl northwest 1/3 of the airspace with a passing -shsn possible. Gusty winds 20-30kt from ~300 degrees.
Sat-Sun . VFR with decreasing winds.
CLIMATE. Closing the books on winter season 2020-2021. Prelim data shows Harrisburg finished as the 28th snowiest on record with a total of 36.0 inches or +11.3 inches above the 30-year average. Total snowfall at Williamsport ranked as the 8th snowiest winter with 53.8 inches or +26.1 inches above the long term mean.
February was also a notable month in the snowfall category as Williamsport (8th snowiest with 22.0 inches), State College (11th snowiest at 25.2 inches), and Harrisburg (18th snowiest with 19.7 inches) set notable marks. Of additional note: February of 2021 was the snowiest February since 2014 at all three sites.
