SYNOPSIS
High pressure continues to move offshore as a series of fronts and low pressure systems affect the East Coast through the end of the week. High pressure looks to return for the weekend and the start of next week.
NEAR TERM /THROUGH TODAY/
The threatening radar across western Pennsylvania Wednesday evening fortunately did not last long, as the earlier line of thunderstorms dramatically weakened while trekking eastward across the state overnight. Some leftover showers will continue to drift across our northwestern zones overnight into early Thursday morning, but removed any mention of thunder in the forecast. Some heftier downpours were passing by Scranton around 1 to 2 AM, with perhaps a rumble of thunder, but that looks like it will be about as close any of that gets to our counties.
Elsewhere, areas of fog over the Pocono Plateau may reach additional higher hills and ridges into NW NJ and SE PA as the low cloud deck lowers, and eventually some areas of fog and drizzle may develop mainly near or north/east of Trenton and toward the shore north of Atlantic City through Thursday morning.
Otherwise, a stationary front looks likely to remain positioned more or less from north central PA southeastward towards the southern end of the Delaware coast. Northeast of the front, low clouds, patchy mist and drizzle may be rather stubborn through Thursday, thanks in addition to the persistent onshore flow off the ocean. Primary low in the Great Lakes will weaken as it hits the high to our northeast with secondary developing along the stationary front and pushing eastward into the ocean on Thursday. Bulk of Thursday looks relatively dry albeit damp and overcast for most of our region, with some reduction in fog and mist/drizzle as the day wears on thanks to the strong April insolation and a slight movement of the stationary boundary northeastward. That said, not expecting it to move much, so lows for most of the region will be in the mid- upper 40s north and east of Philly and low- mid 50s south and west, with highs on Thursday near 50 north and east of Philly. South and west, temps rapidly rise as one reaches and passes the maximum northeastward push of the front, with highs near 70 in far southern Delaware and the Maryland Eastern Shore.
SHORT TERM /TONIGHT THROUGH SATURDAY/
Overall, the short term forecast remains largely unchanged. By Thursday night, the weak coastal low will be shunted south and eastward enough that surface high pressure can build in and briefly shutoff the chances for showers. Lows Thursday night look to fall into the 40s most everywhere across the region.
Following the brief respite from showers Thursday night, the next mid-level wave approaches the region on Friday. Latest guidance continues to indicate that the pre-existing high will be strong enough to hold off any precipitation through the morning. However, the approaching wave will eventually move in and bring yet another cold front across the region with the opportunity for more showers.
Chances for showers begin to increase Friday afternoon and look to peak Friday night. However, the front overall continues to look to be drier so chances for precip Friday night are now around 30-40 percent at most. Showers look to clear the region by late Friday night/early Saturday morning. Temperatures will rise into the upper 50s to low 60s during the on Friday before falling into the upper 40s to low 50s Friday night.
High pressure begins to nudge in on Saturday as the cold front moves offshore. With the exception of some lingering showers in the morning along the coast, everyone should be dry on Saturday with gradually clearing skies. Temperatures will get into the mid to upper 60s.
LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/
The back half of the weekend and into early next week looks rather benign as high pressure continues to settle in on Saturday Night with the front from Friday stalling to the south of the region. Long range guidance is continuing to suggest that a system will slide by just to our south Sunday Night into Monday along the boundary.
Depending on exactly how far south the front stalls, this would potentially allow a few showers to leak back into the most southern portion of the region Sunday Night. Most of the deterministic guidance and ensembles keep the weak area of low pressure far enough south for everyone to stay dry however, and no mentionable PoPs are currently in the forecast. High pressure begins to settle in for Monday/Tuesday with quiet weather anticipated. Another system looks to come in around mid-week with some showers, but guidance varies quite a bit beyond Tuesday.
With the front to the south of the region though, temperatures will likely be below normal through Monday, with highs in the upper 50s/low 60s and overnight lows in the upper 30s/low 40s.
Temperatures look to moderate for the middle of next week, with a return to near normal temperatures.
AVIATION /06Z THURSDAY THROUGH MONDAY/
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas...
Tonight...Lowering to IFR for most sites, with areas of LIFR for a few hours toward 12Z at some sites. Some SHRA passing ABE/RDG and perhaps TTN, while some patchy drizzle may develop toward 12Z elsewhere, reducing VSBY into the 3-5 SM range, if not locally lower, particularly along the coast and across the Poconos. E/NE winds 5 to 10 kt. Moderate confidence.
Thursday...IFR and perhaps local brief LIFR early in the morning with drizzle, gradually improving to low-end MVFR in the afternoon. NE winds 10 to 15 kt. Tricky forecast, particularly with respect to the timing and improvement of ceilings. Low confidence.
Outlook...
Thursday Night...Sub-VFR conditions likely (50-70%) with stratus hanging around.
Friday through Friday Night...Sub-VFR conditions likely (50-70%)
with low clouds through most of Friday and scattered showers moving in Friday Night. Conditions lift to VFR by late Friday Night as a cold front comes through.
Saturday through Monday...VFR expected. Potentially gusty winds on Saturday afternoon.
MARINE
Onshore flow increases over the ocean waters through Thursday.
SCA starts for far northern waters and expands southward to Delaware waters by Thursday night, with easterly wind gusts up to 30 kts and seas 4-8 ft. Winds should stay lighter on Delaware Bay, sub-SCA.
VSBY restrictions in fog and showers tonight, and then fog and light rain and drizzle will persist through Thursday. Cannot rule out a few thunderstorms tonight as well.
Outlook...
Friday...Small Craft Advisory conditions possible (30-40%) for coastal waters north of Cape Henlopen as seas hover around 5 feet.
No marine headlines expected for the rest of the waters.
Friday Night through Monday...No marine headlines expected.
PHI WATCHES/WARNINGS/ADVISORIES
PA...None.
NJ...None.
DE...None.
MD...None.
MARINE...Small Craft Advisory until 6 AM EDT Friday for ANZ450.
Small Craft Advisory from 6 AM this morning to 6 AM EDT Friday for ANZ451.
Small Craft Advisory from noon today to 6 AM EDT Friday for ANZ452-453.
