Area Forecast Discussion National Weather Service Mount Holly NJ 754 PM EDT Mon Jul 6 2020

SYNOPSIS. A frontal boundary remains stalled over the region today but will progress north of the area on Tuesday. 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 will the region Friday through Saturday as it moves north from the Carolinas.

NEAR TERM /UNTIL 6 AM TUESDAY MORNING/. Have see a rapid decrease in the severity for the storms over E Central PA just within the past half hour, so have cancelled the watch for portions of northern and central NJ and Bucks County in PA. Will likely cancel even more of the northern half of the watch within the next 1 to 2 hours.

Previous discussion . We are starting to see coverage and severity of storms decrease across central and northern NJ and and eastern PA as a combination of the building cold pool and loss of peak heating is reducing instability. However, have kept the watch as is for now, as we still have a few storms developing north of the cold pool progressing southeast towards northwestern NJ. However, suspect that the northern half of the watch area may be canceled from the watch within the next hour or two.

Further south, especially across Delmarva, which hasn't seen hardly any of the outflow from earlier convection until now, the severe threat continues and should continue for the next few hours at least.

Heavy rain and flooding will continue to be a concern thanks to weak steering flow and storm training. We have already had one confirmed report of over 5 inches of storm total rain from the north Philly area from earlier storms.

Another concern over night will be fog development especially in locations where heavy rain has occurred earlier today. For now, have just blanketed the area with a mention of patchy fog across the area. However, will refine this further once we see the dew point depressions after sunset.

SHORT TERM /6 AM TUESDAY MORNING THROUGH 6 PM TUESDAY/. Convection looks to continue into the daytime tomorrow, thankfully much more reduced than today. The remnant MCV/MCS from today's convection will be highly influential in convective initiation tomorrow. The lack of a shortwave but rather weak mid-level ridging, this should preclude as widespread convection as today. Forecast CAPE values of, dare say, only 2000-3000 J/kg also indicate weaker convection. Flooding with PWAT values still around still between 1.5-2 inches, is possible, especially over areas that saw abundant rainfall today. Highs will be a bit cooler in the mid to upper 80s as the front from today remains situated further south.

LONG TERM /TUESDAY NIGHT THROUGH MONDAY/. Summary: The extended forecast will feature continually active convective weather likely through next weekend, although the primary focus will be the influence of a departing coastal southern stream low Friday and Saturday.

Synoptic pattern: A fairly progressive pattern is expected, synoptically speaking, into this coming weekend. Tuesday will start with an upper trough departing eastward over the north Atlantic then as trough axis moves from the Great Lakes region east toward the Canadian maritimes by early Thursday. Ridging will follow briefly in the trough's wake late Thursday into Friday, then the attention turns to the southern stream trough digging across the Midwest and eventually into the southeast by Saturday. This trough will be the driver of the next synoptically forced system to impact our region into the weekend. Thankfully, it appears that the medium range guidance is coming into better agreement with regard to timing and evolution of the synoptic pattern during this period.

Sensible weather: The main theme for the upcoming long term period is "unsettled." Basically every day will probably feature convection in some way, shape, or form, however the mesoscale details beyond Tuesday are essentially impossible to determine this far out.

Southerly surface flow will persist Tuesday and Wednesday pumping a continual stream of warm and humid air into the region from the south. So it'll be quite warm and humid, but not excessively so. Expect maximum temperatures nearing 90 degrees and minimums around 70 both days along with dewpoints around 70 degrees along with scattered showers and thunderstorms mainly during the late afternoon and evening time frame.

Tuesday's convection and severe weather environmental setup will be similar to today's with the exception of a few things. Lapse rates will be lower (~6 C/km), so there won't be nearly as much of a hail threat. Precipitable water values will be about the same (1.7-1.9"), but the steering flow will be roughly parallel to the main initiating boundary (oriented E-W across central NJ and eastern PA). So flash flooding could be more of a concern. MLCAPE will remain high (~3000 J/kg) south of the boundary with DCAPE locally over 1000 J/kg. Deep layer shear for organization will be considerably less and flow aloft for forcing is also much less than today, so coverage appears to be much lower. Nonetheless, we will need to watch for wet microburst potential and flash flooding threats with Tuesday's convection.

Synoptically speaking, Thursday appears to be the driest day as a somewhat more prominent ridge passes to our north leading to more subsidence locally. With that said, could still see more isolated convective activity on Thursday. Surface flow will turn more southeasterly as a surface low takes shape across the coastal Carolinas. Still expecting highs right around 90 degrees and lows around 70.

Guidance has come into better agreement that the southern stream coastal low will lift north into the Mid-Atlantic Friday and depart Saturday. This system will bring precipitable water values nearing the "extreme" range for this latitude with values of 2.25-2.50" depicted by the GFS. The precipitation evolution of this system is still quite unclear at this time. I suspect there will be some sort of showery tropical band or bands of rain that lifts north across the eastern portion of the forecast area on Friday followed by more diurnally driven convection later in the day as instability builds. Both the GFS and ECMWF keep the highest QPF offshore, but with surface flow turning easterly with high moisture content, it's difficult to believe that QPF amounts will remain low over land.

On Saturday, the surface low will be departing to the north, but the upper trough axis will remain to our west along with a very soupy airmass and diurnally driven instability. So will still expect to see widespread convection with heavy rain potential. The main takeaway is that there is a heavy rain and potentially flash flooding threat with this system. Thankfully the system will be moving quickly, but it's something that will need to be watched closely.

Temperatures are a bit uncertain Friday and Saturday since cloud cover is a big question mark as of now, but with the tropical airmass that will be advected northward, I see no reason why we couldn't still get highs around 90 degrees. As you may have guessed, dewpoints will rise into the mid 70s Friday and Saturday, so it'll be quite uncomfortably humid regardless of the temperature. Long story short, expect Friday and Saturday to be very warm, wet, and humid.

Without any sort of strong cold front in the wake of this system, it'll likely remain quite warm and humid into early next week.

AVIATION /00Z TUESDAY THROUGH SATURDAY/. The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.

Tonight. Scattered showers and thunderstorms may continue to affect TAF sites through 04Z, especially for further south sites like KILG and KMIV. After 06Z, fog may develop especially at the terminals that received heavy rain today. MVFR at these terminals with IFR possible. Light mostly southeasterly winds. Moderate confidence on the overall patter but low confidence on details like timing.

Tuesday. Once the fog dissipates, mostly VFR conditions are expected. There is another chance for showers and storms after 18Z. However, it is difficult to determine which TAF sites will be impacted at this point. Mostly south winds around 10 knots outside of storms. Moderate confidence for most aspects of the forecast, but low confidence on the potential for storms.

Outlook .

Tuesday 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.

Friday . MVFR ceilings probable with southeasterly to easterly winds around 5-10 kts. Scattered moderate to locally heavy showers with embedded thunderstorms will lower visibility and ceiling restrictions locally.

MARINE. Winds and seas will remain below SCA conditions tonight and Tuesday. Winds may gust around 20 knots at times though. The main hazard through the period will be thunderstorms with gusty winds and locally higher seas.

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 Tuesday through Thursday, which may locally increase winds and seas.

On Friday, seas will build and may exceed 5 feet as winds become easterly and increase to 15 kts with higher gusts possible. Small Craft Advisory conditions are possible on Friday.

Rip Currents .

There is a low risk for the development of dangerous and life threatening rip currents today through Tuesday. However, conditions may be locally moderate near the times of low tide owing to increasing southerly flow through the period.

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.

PHI WATCHES/WARNINGS/ADVISORIES. PA . Flash Flood Watch until 9 PM EDT this evening for PAZ070-071- 102-104-106. NJ . Flash Flood Watch until 9 PM EDT this evening for NJZ015>019. DE . Flash Flood Watch until 9 PM EDT this evening for DEZ001. MD . Flash Flood Watch until 9 PM EDT this evening for MDZ008. MARINE . None.
