SYNOPSIS. One cold front has just cleared the region while a second cold front will cross the region later this evening. High pressure will then build in for Tuesday. Low pressure will pass to the south Wednesday. Another cold front will pass through Wednesday night and Canadian high pressure will build toward the area for late this week into the weekend.
NEAR TERM /THROUGH TUESDAY/. First cold front has cleared the region, with strong northwest flow behind it. Mixing has not quite reached peak, so still think winds will increase strength through rush hour before dropping off around sunset. However, secondary front will arrive later this evening, so kept wind advisory going until midnight as inherited. Added in Allegheny Front and Blue Ridge zones earlier and have some areas going later based on mid-level winds, but expect all areas below advisory strength by late tonight. As there will be a potent vort max supporting the secondary front, it may be accompanied by a few snow showers, maybe even a snow squall, along the Allegheny Front, and a few sprinkles/flurries may reach east of the mountains later this evening/overnight, but overall, a much drier period is anticipated. Lows dropping below freezing across the region.
High pressure builds slowly into the area Tuesday, but it will be considerably colder. Winds should slowly but surely relax, however, and there should also be more sunshine. Highs mostly in the 40s.
SHORT TERM /TUESDAY NIGHT THROUGH WEDNESDAY NIGHT/. Dry period continues through mid-week with high pressure. Lighter winds and not quite as cold Tuesday night as clouds increase a bit while low pressure passes to our south. Milder temperatures Wednesday will prevail thanks to warm advection aloft. Highs should rebound into the 50s. Dry cold front then pushes south across the region Wednesday night, but best cold advection will wait til Thursday, so lows Wednesday night won't be any colder . in fact. likely slightly milder than tonight and Tuesday night, with many areas staying above freezing.
LONG TERM /THURSDAY THROUGH MONDAY/. A breezy northwest flow will prevail Thursday into Friday and keep temperatures below average as the region sits between an upper-level low over eastern Canada and high pressure over the Great Lakes region.
Dry and seasonably cool conditions continue Saturday into Sunday as Canadian high pressure moves overhead. This likely keeps an area of coastal low pressure to the south before heading out to sea. As the broad trough moves east early next week, temperatures will moderate towards seasonal levels.
AVIATION /20Z MONDAY THROUGH SATURDAY/. VFR conditions expected for the next several days. Main concern is winds this afternoon and this evening which may approach 40 knots in gusts. Winds slowly relax later tonight into Tuesday. Could be a stray flurry or rain/snow shower this evening, but most likely, dry conditions prevail.
VFR conditions under northwest winds Thursday into Friday afternoon. Winds could gust to 30 knots behind the cold front Thursday into Friday.
MARINE. Northwest flow likely increases to low-end gale the next few hours as mixing improves, may then back off a bit, then increases once again later this evening as secondary front moves through. After that, winds should gradually start to relax later tonight and Tuesday as gradient relaxes and high pressure builds in. Another front approaching Wednesday with a low passing by to the south could also cause SCA conditions.
A SCA is likely Thursday into Friday as a pressure gradient builds over the region and strong northwest flow prevails.
