Area Forecast Discussion National Weather Service Mount Holly NJ 712 AM EDT Thu Jul 29 2021

SYNOPSIS. A warm front is forecast to lift into our region today as high pressure slides out to sea. A cold front will approach from the Great Lakes today and tonight and it should pass through eastern Pennsylvania, eastern Maryland, Delaware and New Jersey early on Friday. High pressure is anticipated to follow for Friday and Saturday. Another cold front from the northwest is expected to move toward and through our region on Sunday and Sunday night. High pressure should briefly influence our weather on Monday before low pressure passes off the Middle Atlantic coast on Tuesday or Wednesday.

NEAR TERM /THROUGH TONIGHT/. . THERE IS AN ENHANCED RISK FOR SEVERE WEATHER ACROSS THE REGION TODAY .

The key message for today is the threat for severe weather across the region. The Storm Prediction Center has placed a majority of the area in an Enhanced risk for severe weather. The threats will be damaging winds, large hail, and an isolated tornado. The primary threat time will be this afternoon into evening.

Currently, surface high pressure was analyzed across NY and MA with a stalled frontal boundary just northwest of the PA/ NJ border. This frontal zone is leftover from the cold front that cleared the coast yesterday, before retreating back west from an inland moving sea breeze. The aforementioned surface high is already heading east and moving off the coast this morning allowing surface winds to remain calm or light and out of the southeast. This weak surface convergence working in combination with convergence at the nose of a ~20 kt LLJ has allowed for weak showers to form over SEPA and northern DE. These weak showers will continue to expand in coverage this morning and slowly progress east, along with the convergent zone. Simultaneously, an impressive MCS is currently heading south across northern IL. Model guidance has really struggled with how this MCS and attendant MCV will progress through the day today. Even at this stage, CAMs still are having relatively low run to run consistency. The general idea is that the MCV will head southeast over Michigan this morning and approach eastern PA by this afternoon. So what does this mean for us? As described above, the forecast is for the morning showers and isolated thunderstorms to slowly translate east. As this occurs a fractured stratus deck will start to lift. The stalled front currently near the fall line will also lift north as a warm front with rich theta-e air surging northwards. This recycled moisture regime will help to destabilize the region even if the stratus doesn't ever completely clear. Both the GFS and NAM are indicating MLCAPE values of around 1000/1500 J/kg. Still though, the amount of available instability is one of the potential failure modes today (esp. if morning showers prove to be more robust than initially forecast). Generally though, during late July it doesn't take much to destabilize the region.

Early this afternoon the MCV will be approaching from the west with showers and thunderstorms across central PA. Ascent will increase across the region as the MCV approaches. Across the warm sector, effective bulk shear values of ~45 kts will be more than sufficient to support rotating updrafts. Some upscale growth is forecast as multiple cold pools start to be deposited and merge. The primary threats with these storms will be damaging winds, large hail, and an isolated tornado (thanks to slightly back southeast flow and impressive directional shear). The storms look to enter the CWA most likely around 2 to 4 PM and clear the coast by 8 - 11 PM.

As the storms clear the coast, surface low pressure will be located near the NY/Canada border and be dragging a surface cold front through the area. Winds will slowly turn from the northwest through the night with skies slowly clearing from the west.

SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/. A long wave trough will continue to affect the northeastern states from Friday through Saturday night. A couple of short waves are forecast to pass over New York and New England on Friday and Friday night. Any showers associated with short waves will likely remain to our northeast. Surface high pressure is anticipated to slide from the Great Lakes on Friday to the waters off the Middle Atlantic coast on Saturday night, bringing our region dry weather conditions.

The surface high is expected to be accompanied by unseasonably low humidity levels in eastern Pennsylvania, New Jersey, Delaware and eastern Maryland. Dew point readings are forecast to drop into the 50s by late Friday afternoon and they should favor the upper 40s and lower 50s on Friday night and Saturday. They may begin to creep upward into the middle and upper 50s on Saturday night in the return flow as the high moves off the coast.

High temperatures should be mainly in the 80s on Friday and around 80 degrees on Saturday. Readings will likely not get above the lower and middle 70s in the elevated terrain of the Poconos and far northern New Jersey on either day. Lows are anticipated to favor the 50s on Friday night, and the upper 50s and lower 60s on Saturday night.

LONG TERM /SUNDAY THROUGH WEDNESDAY/. The long wave trough is expected to remain over the eastern states from Sunday through Wednesday. A closed low may develop over Ohio and vicinity on Wednesday. The pattern will prevent the heat and humidity from building back into our region. Daytime highs should favor the range from the upper 70s to the middle 80s with overnight lows mostly from the upper 50s to the middle 60s.

A mid level short wave and its associated surface cold front are anticipated to approach from the northwest on Sunday before making their way across our region on Sunday night. We are mentioning a chance of showers and thunderstorms mainly from Sunday afternoon into Sunday evening. The cold front is expected to nearly stall to our south on Monday as high pressure builds from the Great Lakes into the northeastern states.

Low pressure developing and traveling along the cold front to our south should impact our weather in the Tuesday and Wednesday time frame. The guidance differs on the details, timing and number of waves of low pressure, so we will simply keep a chance of precipitation for both days.

AVIATION /12Z THURSDAY THROUGH MONDAY/. The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.

Through 12z this morning . Surface high pressure continues to pull east off the coast of NY with a weak convergent boundary forming near KILG to KRDG with showers and even a few rumbles of thunder. This weak convergent boundary will continue to push northeast, along with the showers and isolated thunderstorms. High confidence.

Today . MVFR cigs in the morning will likely be rather sporadic. By early this afternoon an upper level disturbance and corresponding surface low pressure will be quickly approaching from the west. This wave will then likely ignite showers and thunderstorms this afternoon. Winds will generally be in the 5 to 10 kt range and gradually shift from SE southerly then to SW/W very late day towards 0z. However, stronger and erratic winds are likely in and near thunderstorms. Moderate confidence overall with low confidence in thunderstorm timing.

Tonight . Becoming VFR after evening showers/thunderstorms and associated restrictions. Cold front moves through. Winds gradually shifting from the northwest with prevailing speeds 5 to 10 kt. High confidence.

Outlook .

Friday . Mainly VFR. Northwest wind 10 to 15 knots with gusts of 20 to 25 knots. High confidence.

Saturday . Mainly VFR. Northwest wind 5 to 10 knots, becoming southwest. High confidence.

Sunday . Some early morning low clouds and visibility restrictions are possible, otherwise mainly VFR. A chance of showers and thunderstorms in the afternoon and evening. South to southwest wind around 10 knots. Medium confidence.

Monday . Mainly VFR. Northwest wind around 10 knots. Medium confidence.

MARINE. This morning . Sub-SCA conditions expected with southeast winds around 10 kts. Seas 2 to 3 ft.

This afternoon into tonight . Winds will continue strengthen as the pressure gradient tightens with gusts very close to or at SCA criteria. Seas building 3 to 4 ft. Given the above, have issued an SCA for the Atlantic Coastal waters starting at 2 PM this afternoon and continuing until midnight tonight. Thunderstorms will cross the waters late this afternoon into evening. Winds and seas will be higher in and near thunderstorms.

Outlook .

Friday through Monday . No marine headlines are anticipated.

Rip currents .

Winds will increase to 15 to 20 kts today with gusts at SCA criteria. There will be an onshore component for the NJ coast today as winds veer from the south. Given the above, and the 8 second period forecast, the rip risk for Coastal Cape May and Coastal Atlantic will be MODERATE today. The rest of the beaches will be kept at LOW given the orientation of the coastline relative to the wind direction. Winds shift offshore for Friday, so the rip risk for Friday will be LOW.

PHI WATCHES/WARNINGS/ADVISORIES. PA . None. NJ . None. DE . None. MD . None. MARINE . Small Craft Advisory from 2 PM this afternoon to midnight EDT tonight for ANZ450>455.
