Synopsis for the tidal potomac and md portion of the chesapeake bay.. High pressure shifting offshore will bring a southerly return flow beginning late tonight. An arctic front will then turn winds back to the northwest by Thursday, and may be accompanied by rain changing to snow. Low pressure lurking just off the east coast as cold high pressure anchors to the north could set the stage for another winter storm Friday into Saturday. Small craft advisories will likely be needed at times through Thursday, with near gale conditions possible as low pressure passes through early this weekend.

Area Forecast Discussion National Weather Service Mount Holly NJ 935 PM EST Tue Jan 18 2022

SYNOPSIS. High pressure is forecast to build into our region from the west and southwest for tonight and it should move quickly out to sea on Wednesday. A cold front approaching from the northwest is expected to arrive early on Thursday. Frigid high pressure is anticipated to follow for Thursday night into the weekend, when an area of low pressure should pass off the Southeast Coast. High pressure is forecast to return for Monday with a cold front expected to arrive on Tuesday.

NEAR TERM /THROUGH WEDNESDAY/. Evening update .

No significant changes to the forecast, and no weather concerns are expected tonight Previous discussion follows.

Surface high pressure extended from the southeastern states up to Quebec this evening. The air mass is expected to move quickly out to sea, leaving our region in a developing and relatively mild southwest flow. We should see an increase in high clouds tonight, along with perhaps some mid level clouds over parts of eastern Pennsylvania and northern New Jersey late tonight. Lows are anticipated to favor the upper teens and 20s.

No precipitation is expected for Wednesday, even as high pressure loses its influence over our region. A southwest wind is forecast to increase to 10 to 15 MPH. Afternoon temperatures should rise into the 40s in much of our area.

SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/. A surface cold front will be approaching the area from the west with surface low pressure heading towards the Canadian Maritimes. The surface cold front will quickly cross the area Thursday morning as upper level energy across the central United States heads northeast. Precipitation will initially start out as mostly rain, before changing over to snow by Thursday morning. The change over will likely start across the northwestern zones late Wednesday night/ early Thursday morning and reach the I-95 corridor right around the morning rush hour (if not slightly sooner). The latest QPF guidance continues to show a quarter to a half of an inch of total precipitation. Overall, have slightly raised snowfall amounts as a quicker transition over to snow is forecast. Given the above, the current forecast is for an areal average of 1 to 2" of snowfall. The confidence on the exact snowfall amounts is average here, but the probability of measurable snowfall is higher for almost the entire area.

Snowfall will then start to exit the region Thursday afternoon from the northwest. High temperatures will likely occur early Thursday and hold steady most of the day Thursday right around freezing with the ongoing snowfall. Skies will slowly start to clear from northwest to southeast Thursday night.

LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/. The rather active and below normal temperatures will continue through the long term with Friday morning bringing the coldest temperatures of the period with a potential for snow Saturday into Sunday. This is thanks to a long wave trough axis centered across the Eastern United States with a potent mid-level ridge centering just off the west coast of the United States. This will allow for multiple perturbations to round the base of the long wave trough axis, as well as allow for multiple cold air intrusions across the region. The exact details of how each wave progresses will set the stage for what happens here locally.

For Friday, a surface cold front will be well south of the region with surface high pressure centering near the Ontario/ Quebec border. Temperatures Friday morning will be cold with lows mostly in the teens expected. Towards the higher terrain of the Poconos near 0 degrees appears likely.

Friday night into Saturday, a wave diving southeast out of central Canada will round the base of the long wave trough axis and head east. As the mid-level wave exits the east coast of the United States surface low pressure is forecast to form off of the NC coast. The latest run of the GFS, ECMWF, and CMC have the low offshore, but confidence is low here. It should also be noted that the energy responsible for the surface cyclogenesis is still across northern Alaska, meaning a lot can change. Have gone ahead and kept PoPs in the chance range at this point. Global guidance also has the potential for another low pressure to form Sunday as the southern stream energy exits off the east coast of the United States. Confidence with this system is even lower though.

AVIATION /03Z WEDNESDAY THROUGH SUNDAY/. The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.

Tonight . VFR. West to southwest winds around 5-10 knots, becoming variable 5 knots or less for most areas. Any site that keeps a wind direction will become south to southwest overnight. Low level wind shear developing between 09z-11z as a low level southwesterly jet around 40 knots moves overhead. High confidence.

Wednesday . VFR. Low level wind shear until around 13z-15z. Southwest wind increasing to 10 to 15 knots with gusts around 20 knots. High confidence.

Outlook .

Thursday . Rain changing to snow in the morning before ending in the afternoon. The rain and snow will lower cigs and vsbys to MVFR/IFR with improvement to VFR in the afternoon. Northwest wind 10 to 15 knots with gusts around 20 knots. Medium confidence.

Friday . Mainly VFR. North wind around 10 knots. High confidence.

Saturday . A chance of snow with MVFR/IFR conditions possible. North wind around 10 knots. Low confidence.

Sunday . Snow exiting the region with VFR conditions. West winds mostly less than 10 knots. Low confidence.

MARINE. The Small Craft Advisory for this evening has been cancelled, with conditions now sufficiently below criteria. Sub-SCA conditions will continue through the night with winds becoming southwesterly at 10 to 15 kt and seas 3 to 4 ft.

A new Small Craft Advisory has been issued for both the Atlantic coastal waters as well as Delaware Bay for Wednesday. Southwest winds will increase in the morning, with gusts of 25 to 30 kt likely for most of the day. Seas will also increase to 5 to 7 ft. Winds should start to diminish during the evening. On the Atlantic coastal waters, the advisory extends through Wednesday night due to the seas, but they should diminish later Wednesday night as well.

Outlook .

Thursday . Northwest wind 15 to 20 knots with gusts near or just below 25 knots.

Friday and Saturday . North wind around 20 knots with gusts of 25 to 30 knots. Winds will slowly veer from the northeast Friday night, before backing from the north once again by Saturday evening.

Sunday . North winds relaxing from the west around 15 knots.

PHI WATCHES/WARNINGS/ADVISORIES. PA . None. NJ . None. DE . None. MD . None. MARINE . Small Craft Advisory from 7 AM Wednesday to 6 AM EST Thursday for ANZ450>455. Small Craft Advisory from 7 AM to 7 PM EST Wednesday for ANZ430-431.
