SYNOPSIS. A mainly dry cold front will pass through this evening, then high pressure will press down from Nunavut and Hudson Bay. Temperatures will drop back to well below normal Thursday and last for the entire weekend. A pronounced warming trend is projected for next week. The next widespread chance of precipitation will be rain showers in the middle of the upcoming week when a storm approaches from the west.
NEAR TERM /THROUGH TONIGHT/. Sharp change coming as we have risen well above normal maxes this aftn. A couple of mainly dry fronts will push across this evening/early tonight. While I do have a couple of spots of 20-30 PoPs in the nrn half and far wrn mtns, the moisture will be severely lacking and clouds may try to precipitate, but it may not get to the ground. High bases are expected to the clouds at first, then lower as the air gets colder and the big inversion traps the moisture under itself. Even when they do lower after midnight, they will still be lacking sufficient moisture. There could be the lightest of dustings across the far N with just the addition of the lake moisture. Lots more open water on LE than just last week. Temps will drop into the m20s N and near freezing in the valleys of the SE.
SHORT TERM /THURSDAY/. Northwest flow continues and strengthens/gets gusty with frequent gusts into the 20s, esp in the S, on Thursday aftn. The clouds trapped under the inversion over the NW half/two-thirds will break up quite nicely for much of the area. The Alleghenies and Laurels will hold onto clouds all day. Maxes will be helped into the m40s in the SE thanks to the downslope warming. Maxes will stay in the 20s for the nrn mtns. Arctic high pressure will extend down into the Gulf Coast states. The coldest of the air will be pressing through the lower lakes and New England.
LONG TERM /THURSDAY NIGHT THROUGH WEDNESDAY/. Quite a bit of redundancy in the local forecast for the long range period. Fri-Sun will be nearly equal in the temp department. Clearing will mainly be for the srn half of the area Fri and Sat with the high sliding down, but the axis staying to the west. Nrly flow will keep lake-induced clouds at least sct if not bkn/ovc for the N & W. Inversion finally crashes on Sunday. Expect lots of sunshine and light wind for Sun and Mon. Maxes will climb a little on Monday, but flow from a lower latitude really doesn't show up until Mon or Tues. So, the abnormal warmth returns for the middle of next week - some locations will get into the 60s. The upper ridge to our west finally slips eastward and the axis passes overhead Tues, and brings substantial moisture into the OH valley and Upper Great Lakes for the middle of the week. ECMWF is slower with arrival of any precip (showers (thunder?)) than the GFS. So, have kept the Wed/Day8 PoPs below 30 PCT for most of the area.
AVIATION /20Z WEDNESDAY THROUGH MONDAY/. Sky has cleared nicely with wind picking up as expected. Clouds should remain tough to find until close to sunset. MVFR to low VFR cigs are likely to return to the northern mountains and Laurels between midnight tonight and the predawn hours Thu, then stick around through late Thu afternoon.
Gusty westerly winds this afternoon will decrease just a little overnight, before shifting more to the NW and becoming gusty again on Thu in a colder post frontal airmass.
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 the meteorological winter (Dec-Feb) 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.
