Area Forecast Discussion National Weather Service Mount Holly NJ 342 PM EDT Tue Jul 14 2020

SYNOPSIS. Surface high pressure builds over the Northeast tonight, and then a backdoor cold front slides through the region on Wednesday as the high moves offshore. A warm front lifts north on Thursday, followed by a cold front late Friday. Another cold front approaches over the weekend. Bermuda high pressure becomes entrenched off the Southeast and Mid-Atlantic coasts for the start of the new week.

NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/. The mid level trough passes offshore tonight. Some energy rotating through the mid level flow will pass across our area this evening. There is the possibility that a few showers may brush our northern areas (as several CAMs show, but mainly just east of our CWA) but confidence is too low to include in the gridded forecast.

Otherwise, the cumulus that developed today will dissipate around sunset, leaving relatively clear skies for tonight. The gusty northwest winds will taper off this evening and become light, generally around 5 mph or less throughout the forecast area. With the high pressure starting to slide across the region tonight, the winds will gradually turn to the north and then east overnight. Overnight lows will drop down into the low to mid 60s through much of the region. The urban corridor and along the coast may remain in the upper 60s to near 70. The southern Poconos and portions of northwest New Jersey may fall into the upper 50s.

SHORT TERM /6 AM WEDNESDAY MORNING THROUGH 6 PM WEDNESDAY/. High pressure will slide to the east, with the center remaining to the northeast of our area. This will put us in an easterly flow, which is expected to help keep the temperatures a bit cooler and fairly comfortable. Even though the mid level ridging may help to warm temperatures, the 850mb temps are supportive of slightly cooler temps (more in the 15-17C range as opposed to the previous 17-19C range they showed days ago). Temperatures inland are more likely to hold onto the warmth though as the easterly flow may take a while to really take hold there. Having said that, there is definitely some bust potential here for daytime highs. One thing that will occur is the increasing low level moisture as the easterly flow takes hold across the region so expect dew points to start creeping up once again. Expect clouds to develop again through the day, and in some places may be more scattered to broken.

Even with the increasing moisture, there are no real triggers to get any sort of pop up showers to develop so anticipate another dry day across the region.

Daytime highs will generally be in the 80s throughout the forecast area with some upper 70s in the higher elevations and along the immediate coast.

LONG TERM /WEDNESDAY NIGHT THROUGH TUESDAY/. Surface high pressure moves into eastern Canada and the Canadian Maritimes Wednesday night, and as it does, a backdoor cold front will slide down the Northeast and into the Mid-Atlantic. Onshore flow develops, but given how dry it is ahead of this front, not expecting any precip with its passage. Some patchy fog may develop with the onshore flow, however.

Surface high pressure will extend from the Canadian maritimes, through the Gulf of Maine, and into eastern Long Island, and this will be combined with mid-level ridging along the East Coast on Thursday. These should help slow the progression of an approaching cold front, and keep most of Thursday dry. A cooler day, with highs generally in the 80s, but surface dew points will begin to creep up through the mid 60s. Although some showers and thunderstorms are possible in the afternoon, they will be confined to portions of the southern Poconos and Berks county.

The trend for a slower progression of the front continues Thursday night and Friday. Scattered showers and thunderstorms will approach the I-95 corridor Thursday night, but the bulk of the activity will hold off until Friday afternoon. A pre-frontal trough develops out ahead of the front, and this will be the trigger for afternoon and evening convection. Temperatures will not be overly hot on Friday, generally topping off in the mid to upper 80s, but it will be quite humid, with surface dew points in the low 70s. 12Z GFS is indicating surface based CAPE values 2000-2500 J/kg, possibly as high as 3000 J/kg along the urban corridor, along with upwards of 2500 J/kg MUCAPE. PWATs are 2-2.5 inches. Not much shear, though. Could end up being more of a heavy rain threat than a severe weather threat, but there is still plenty of time to work out the details.

The front probably will not make it through the region until Saturday, but the front seems to get hung up just offshore. Dew points only marginally drop off Saturday afternoon, and because of this slight drying out period, temperatures should warm quite nicely into the upper 80s and around 90. Another weak front approaches on Sunday, but seemingly washes out before it gets here. Convection is possible on Saturday, and would only be limited to the far western zones on Sunday.

From there, Bermuda high pressure will set up offshore, and strong return flow will develop across the region. A hot and humid airmass will build into much of the Northeast and Mid-Atlantic with some of the hottest and most humid weather of the season. Expecting highs topping off in the mid to upper 90s, along with dew points well in the 70s. Could be a situation where the highest dew points (74-77) occur during the overnight hours, and only marginally drop off in the afternoon (71-74) due to afternoon heating and mixing. Either way, widespread Heat Index values of 100-105 are becoming likely for a vast majority of the forecast area for the first half of the new week, and Heat Advisories may be needed, if not Excessive Heat Warnings.

Afternoon and early evening convection is possible Monday and Tuesday, given the instability due to the heat and humidity, as thermal troughs develop west of the region, aided by some mid- level shortwave energy.

AVIATION /20Z TUESDAY THROUGH SUNDAY/. The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.

Tonight . VFR conditions expected. Light northwest winds becoming easterly overnight. High confidence.

Wednesday . VFR conditions expected. Few to scattered cumulus through the afternoon. East to southeast winds around 10 knots with some gusts around 15 to 20 knots possible. Moderate confidence.

Outlook .

Wednesday night . Generally VFR, but cannot rule out sub-VFR conditions in fog. Light E-SE winds. Low confidence on CIGs/VSBYs, moderate confidence on winds.

Thursday . Mainly VFR. SE winds 10-15 kt. Moderate confidence.

Thursday night through Friday night . A chance for SHRA/TSRA with sub-VFR conditions. Otherwise VFR. Patchy fog possible during the overnight hours, especially in locations where rain occurred. SE winds Thursday night, becoming S on Friday, the SW Friday night, generally 10-15 kt, though lighter at night. Low confidence.

Saturday . Scattered SHRA/TSRA with sub-VFR conditions possible. VFR otherwise. W-SW winds 5-10 kt. Moderate confidence.

Sunday . VFR. SW winds 5-10 kt. Moderate confidence.

MARINE. Sub-advisory conditions are expected to continue on the area waters through Wednesday. West to northwest winds around 10 to 15 knots with gusts around 20 knots through this afternoon. Winds will become northerly and then easterly through Wednesday. Seas around 2 to 3 feet on the ocean.

Outlook .

Wednesday night through Thursday . Sub-SCA conditions expected with fair weather.

Thursday night through Saturday . Although conditions will mainly be sub-SCA, a prolonged southerly flow may result in 15-20 kt winds, along with seas building to around 4 feet. Showers and thunderstorms may result in locally higher winds and waves, especially Fri are day afternoon and Friday night. Another round of showers and thunderstorms is possible Saturday.

Sunday . Sub-SCA winds and waves expected.

Rip Currents .

Breaking waves are forecast to be 2 feet or less with a medium- period southeast swell along the coasts of Delaware and New Jersey today. Winds are forecast to settle into the south around 5 to 15 mph in the afternoon. The risk for the development of dangerous rip currents is expected to be low.

The wave and swell conditions are anticipated to remain nearly the same for Wednesday. However, the wind is forecast to become easterly around 10 to 15 mph. The low risk of rip currents is expected to continue.

EQUIPMENT. The NOAA Weather Radio All Hazards broadcast from Hibernia Park, PA (WNG704) remains off the air until further notice due to damage to the antenna during the June 3 derecho.

The NOAA Weather Radio All Hazards broadcast from Philadelphia, PA (KIH28) is currently off the air. Technicians have been notified, but a return to service is unknown at this time.
