Area Forecast Discussion National Weather Service Mount Holly NJ 1025 AM EDT Sun Jul 5 2020
SYNOPSIS. A series of surface boundaries will meander across the region through early in the week when high pressure toward the west and prevailing southerly flow begin to take control. A summer-like pattern will then persist throughout the week with scattered showers and thunderstorms expected most days along with above average temperatures. A coastal storm may impact the region later in the week and into next weekend as it moves north from the Carolinas.
NEAR TERM /UNTIL 6 PM THIS EVENING/. No changes to the forecast so far today. Previous forecast discussion has a good handle on the situation, so have made no changes to it.
Weak cold front extends from northern New Jersey, down along the I-95 corridor, and into southern Pennsylvania. This front will continue to sag southward through the day. An upper trough lies over the Northeast and some weak shortwaves will slide down the trough and through portions of southeast Pennsylvania, southern New Jersey, and Delmarva.
With the front essentially bisecting the forecast area, there will be two different air masses over the region. North of around I-195, surface dew points will be in the mid to upper 50s with highs in the mid 80s in the southern Poconos, and in the upper 80s to low 90s elsewhere.
South of I-195, surface dew points will be in the upper 60s to around 70, and highs will top off in the low to mid 90s, with the highest temps along the I-95 corridor from Newark to Trenton to Philly. Max heat index values will top off in the upper 90s across interior portions of Delmarva and interior portions of southern new Jersey.
In these areas, surface based CAPE and MU CAPE values will rise to 2500-3000 J/kg. As the combination of the aforementioned cold front and shortwaves sag into these areas, widely scattered showers and thunderstorms will develop this afternoon. Will keep PoPs capped at chance, as it does not look like convection will be organized, but hi-res short term models show storms firing up in these areas. With moisture pooling across Delmarva and southern New Jersey, there will be enough energy to support convection, and even some stronger storms.
Downdraft CAPE values will be upwards of 1500-2000 J/kg in those areas as well, so some strong thunderstorm wind gusts are possible. Will add gusty winds enhanced wording to the forecast.
PWATs will be between 1.5-1.75 inches, so locally heavy rain is possible. HREF ensemble mean 6-hr QPF forecast showing over one inch of QPF across portions of southeast Delaware this afternoon, so this is something to watch out for, especially after 1pm.
With wet-bulb 0 heights around 10,000-11,000 feet, it would not be surprising to see some small hail as well today.
Important to note that convection will not be widespread, and not everybody in Delmarva and southern New Jersey will experience thunderstorms today. But those that do can expect strong thunderstorm wind gusts and heavy rain.
SHORT TERM /6 PM THIS EVENING THROUGH 6 AM MONDAY/. Storms taper off early this evening as the cold front pushes south and shortwaves depart. High pressure builds in from the west. Skies clear out and winds become nearly calm.
Possible for patchy fog to develop after midnight tonight, especially in areas where it rain this afternoon. However, there will be enough ripples in the mid and upper levels of the atmosphere to keep widespread dense fog from developing.
Lows tonight will be in the mid and upper 60s for most of New Jersey and southeast Pennsylvania, and in the low 70s in the urban corridor from Trenton to Philly, and across Delmarva.
LONG TERM /MONDAY THROUGH SATURDAY/. Long term forecast update: No significant changes were made with this update. Overall, a slightly warmer than average period is forecast through the week as synoptic scale ridging builds with continued chances for diurnally driven showers and thunderstorms most days.
For Monday, a few ripples in the mid-level flow will be enough to initiate showers and thunderstorms. Convection could certainly become locally severe as a high CAPE and DCAPE thermodynamic environment will be in place. MLCAPE in excess of 3000 J/kg and SBCAPE nearing 4000 J/kg is expected along with DCAPE in the 1000-1400 J/kg range, steep low level lapse rates, and some mid- level dry air. Bulk shear is low though, only 15-20 kts, so convection will likely be single to multi-cellular and pulsy. Microburst potential is not out of the question with any of the more robust cores that develop. Also cannot rule out severe criteria hail as well as mid-level lapse rates are not too shabby around 7 C/km. The best severe potential looks to be from the 4 PM to 8 PM time frame, although showers and storms could develop and persist outside of this time frame.
A more organized synoptic scale system may impact the area later in the week in the form of a coastal storm, where more widespread precipitation is possible, however uncertainty still remains with regard to the evolution of this system. Details beyond Monday follow in the previous discussion below .
Previous discussion . A quiet start to the extended Tuesday as ridging expands eastward across the eastern U.S. ahead of a developing synoptic trough across the West Coast. The stalled fronts mentioned previously mentioned in the the synopsis above will begin to retreat northward as a warm front. To our north, a potent shortwave and surface low look to move across central Canada into the Hudson Bay region. Meanwhile, a southern stream perturbation will work its way across the Gulf Coast as surface low pressure begins to form. Widely scattered showers and thunderstorms both afternoons appear likely with the front in the vicinity and forecast SB CAPE values from 1000 to potentially 3000 J/kg. Highs will be seasonably warm in the upper 80s to low 90s.
The aforementioned low to our south looks to enter the Carolinas Thursday, but this is where model discrepancy becomes more noticeable. The GFS takes the center inland across the Piedmont, while the EC keeps the center off the coast. Another factor of question is how this surface low will interact with an approaching shortwave trough across the Great Lakes Friday into Saturday. If the GFS prediction has its way, a wetter forecast looks to take place for our region, but if the low stays well enough offshore, we may remain sandwiched between both features, going mostly unscathed.
Am somewhat more inclined to believe the EC at this time given previous environmental support for cut-off lows this year, but kept wide chance PoPs for the region through the weekend. Wouldn't call it a washout, but will want to monitor the forecast as model agreement on storm track solidifies. Highs look to remain seasonable in the mid to upper 80s across the region Friday and Saturday.
AVIATION /14Z SUNDAY THROUGH THURSDAY/. The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.
Today . Generally VFR. Scattered SHRA/TSRA possible at KILG, KMIV, and KACY this afternoon. Brief IFR conditions and strong thunderstorm wind gusts are possible at these sites should storms pass over the terminal. LGT/VRB winds this morning, becoming W-SW 5-10 kt this afternoon. Moderate confidence.
Tonight . Generally VFR, except sub-VFR in fog possible at KMIV and KACY, especially if thunderstorms develop there this afternoon. SW winds 5 kt or less. Moderate confidence.
Outlook .
Monday through Thursday . Prevailing VFR expected, however scattered showers and thunderstorms, generally between 18Z and 06Z each day, may locally lower restrictions. Winds will be generally southerly around 5-10 kts.
MARINE. Today through tonight . Conditions will be below Small Craft Advisory conditions with S-SW winds 10-15 kt. Seas on the ocean will range from 2-3 feet. Scattered showers and thunderstorms are possible over Delaware Bay and southern New Jersey and Delaware ocean waters this afternoon that could result in wind gusts 30-35 kt and VSBY restrictions in heavy rain.
Outlook .
Conditions are forecast to remain below advisory criteria through Thursday, however southerly winds may gust up to 20 kts at times. Seas will be generally 2-3 feet. Afternoon and evening showers and thunderstorms are possible Monday through Thursday, which may locally increase winds and seas.
Rip Currents . There is a low risk for the development of dangerous and life threatening rip currents today and Monday. Conditions may become locally moderate today at some beaches across southern New Jersey should southerly flow be a bit stronger than currently forecast. Scattered thunderstorms with heavy rain and gusty winds are possible at southern New Jersey and Delaware beaches this afternoon as well.
TIDES/COASTAL FLOODING. Tide levels will begin to decrease today, and with winds shifting slightly offshore, only spotty minor coastal flooding is possible with the evening high tide cycle tonight.
Tidal flooding is not expected on the upper eastern shore of Chesapeake Bay.
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.
