Area Forecast Discussion National Weather Service Mount Holly NJ 928 PM EST Mon Jan 27 2020

SYNOPSIS. Low pressure over the Gulf of Saint Lawrence will slowly shift eastward through tonight. A weak cold front will move through late Tuesday into Wednesday. High pressure will build into the region for the middle and latter portion of the work week. Coastal low pressure may affect the area over the weekend followed by high pressure likely returning for early next week.

NEAR TERM /THROUGH TUESDAY/. A mid level low will remain over the Gulf of Saint Lawrence tonight. The low will pull a short wave trough over our region tonight.

Clouds are lingering this evening and are expected to clear late as the short wave passes through the region.

West winds around 10 mph this evening should diminish to 5 to 10 mph through the overnight. Low temperatures are forecast to range from the middle 20s to the lower 30s in eastern Pennsylvania, New Jersey, Delaware and northeastern Maryland.

SHORT TERM /TUESDAY NIGHT THROUGH 6 PM TUESDAY/. We are expecting subtle mid level ridging overhead for Tuesday morning before another short wave trough begins to approach from the northwest during the afternoon. As a result, we are anticipating generally scattered cloud cover to start the day with an increase in stratocumulus in the afternoon, especially over eastern Pennsylvania and northern New Jersey.

A northwest wind is forecast to increase to 10 to 15 mph with gusts around 20 mph. Highs should be in the lower to middle 40s, with readings not getting above the 30s in the elevated terrain of the Pocono Region and far northern New Jersey.

LONG TERM /TUESDAY NIGHT THROUGH MONDAY/. Tuesday night through Thursday .

Tranquil, precipitation free weather expected for this part of the forecast as high pressure will be gradually building in from the north. Forecast models in good agreement on this. Temperatures will also be right around average for this time of year with both Wednesday and Thursday featuring a good deal of sunshine. High temperatures both days look to be in the 30s to low 40s.

Thursday night through Monday .

The main story for this part of the forecast continues to be the potential storm system for the weekend. There continues to be both inter and intra model variability on how this will play out but the overall idea from recent runs of the deterministic models is for full phasing of upper energy from the northern and southern streams not to occur which would result in a weaker system tracking farther east. However this could still change. In the meantime, high pressure centered over the region continues to dominate through Thursday night. The resulting clear skies and light winds should yield good radiational cooling conditions so forecast lows are a little below model consensus. Generally expect lows by Friday morning ranging from the upper teens to mid 20s.

Forecast uncertainty starts to increase heading into Friday. In the big picture, upper level pattern will be becoming more amplified with an upper level trough setting up centered from the Great Lakes south to the Gulf coast. There will be numerous shortwaves rotating through this upper level trough and an incipient low pressure system near the eastern Gulf. An inverted trough may extend north from this towards the mid Altantic. How this all jells together and whether it brings the mid Atlantic a storm system for next weekend is still very uncertain as the upper level energy that will come into play here is still over the Pacific. As early as Friday though there could be a few showers around due to the aformentioned inverted trough but this should be mainly near the coast if it occurs at all.

As already mentioned, lots of uncertainty in the forecast for next weekend. Deterministic GEM, GFS, EC currently favoring low pressure to move north and east off the coast with the brunt of the system staying out to sea as low tracks S/E of the 40/70 point lat/lon point. Some differences in timing though with the GFS showing the system's closest pass to the region during the day Saturday while the EC and GEM are about 12 hours slower. Also worth noting, several of the 0z GFS ensemble perturbations continue to show a much stronger storm system moving north along the coast or even inland so this scenario is still possible. So this all said, we continue to forecast chance POPs over the weekend with precip type tending to favor rain or at least a mix for areas near and S/E of the I-95 corridor due to lack of antecedent cold air mass.

Indications at this point are for high pressure to return early next week.

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

Tonight . VFR with decreasing clouds. West to northwest wind 5 to 10 knots. High confidence.

Tuesday . VFR with an increase in cloud cover. Northwest wind 10 to 15 knots gusting near 20 knots.

Outlook .

Tuesday night-Wednesday night . VFR with NW winds generally 5-10 knots though Wednesday. Winds turning light northerly on Wednesday night. High confidence.

Thursday-Thursday night . VFR. Northeast winds 5 to 10 kt on Thursday becoming light and variable Thursday night. High confidence.

Friday . Mainly VFR, but MVFR is possible especially southeast of PHL and especially later in the day due to possible rain showers and low stratus. Winds light and variable. Moderate confidence.

Friday night - Saturday . Restrictions possible, mainly for I-95 TAF sites and points south and east due to potential coastal system. Low confidence.

MARINE. A west to northwest flow will continue over the coastal waters of New Jersey and Delaware for tonight and Tuesday. Speeds are expected to favor the 10 to 20 knot range. However, there may be some 25 knot wind gusts from late tonight into Tuesday morning in the southern part of our marine area in the wake of a mid level trough. As a result, we will issue a Small Craft Advisory for the period from midnight until noon on Tuesday. It will cover our coastal waters from the Atlantic City area southward and the lower part of Delaware Bay.

Outlook .

Tuesday night-Friday . Quiet conditions expected on the waters through this period with sub SCA conditions expected. NW winds could gust to 20 knots Tuesday night into early Wednesday with winds shifting to NE for Wednesday night and Thursday.

Friday night - Saturday . Sub SCA conditions favored but if a coastal system tracks close enough to the waters SCA winds/seas are possible.

PHI WATCHES/WARNINGS/ADVISORIES. PA . None. NJ . None. DE . None. MD . None. MARINE . Small Craft Advisory until noon EST Tuesday for ANZ431-452>455.
