SYNOPSIS
A cold front settles south and east of our area tonight before moving back north as a warm front Wednesday night into Thursday.
A weak cold front then settles to our south Thursday night into Friday. Another cold front slowly approaches Saturday and Sunday, then it gradually settles to our south and east early next week.
NEAR TERM /THROUGH WEDNESDAY/
Following the passage of a backdoor cold front coming in from the northeast last night, actually reaching down past Philadelphia with a push of cool air on northeast winds, we had low clouds across the northeastern half of the area this morning. Those clouds have since cleared the vast majority of our area, except right along the shore from Barnegat Light northward, where the chilly marine air is fending off the push of milder air from the south and west. Temperatures there are actually stuck in the mid to upper 50s this afternoon.
Meanwhile, in areas where the cool air did not push in, highs temperatures are into the 80s this afternoon, even up to around Philadelphia. In between that, temperatures vary from the 60s across much of northern NJ to the 70s closer to the Delaware and Lehigh River Valleys down to around Trenton.
As a result of that push of cooler air, the atmosphere is relatively stable across much of northern and eastern NJ.
Meanwhile, RAP analysis suggest around 1000 j/kg of CAPE from near the Poconos down to near Wilmington Delaware. That will be a key factor for showers and thunderstorms trying to push into our region from the west and northwest as we head into this evening. A shortwave trough and a weakening cold front are helping to trigger showers and thunderstorms this afternoon across central PA and upstate NY, but due in part to less instability and moisture, there is very limited cumulus development in our area, and when this activity encounters the more stable air toward NJ, they will be weakening.
That said, along with the CAPE mentioned above, there is 800-1000 j/kg of DCAPE analyzed by the RAP across eastern PA as well, and effective bulk shear of around 40 kt. SPC has added our area into a 'marginal' risk of severe thunderstorms, and that seems on point given these conditions. CAMs continue to suggest activity will start to move into our area toward 5 PM, and particularly between 6-8 PM, possibly reaching the I-95 corridor around 8-9 PM, but likely weakening as it does so.
Expect the main threat with any of these storms to be gusty winds, capable of bringing some tree limbs down, but that threat will diminish toward sunset and as the storms reach the more stable air closer to the Delaware River Valley.
Showers will continue to weaken and diminish in coverage heading toward midnight, but with the trough still yet to move through, some light showers will linger, mainly east of I-95, possibly through dawn on Wednesday. Some vorticity may continue to advect in on WNW flow aloft in the wake of the main trough on Wednesday. However, moisture will be very limited, and the atmosphere will be fairly stable, so while a pop up shower, perhaps along the sea-breeze, cannot be completely ruled out, do not have anything mentioned in the forecast. Otherwise, Wednesday looks like it will turn out to be a fairly pleasant day as clouds tend to give way to sunshine, especially away from the coast. Look for highs mainly in the 70s, but much cooler toward the shore thanks to a pronounced onshore breeze.
SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY NIGHT/
As a shortwave trough slides across New England Wednesday night and Thursday, an upper-level ridge is forecast to build eastward with its axis cresting our region Friday or Friday night. At the surface, weak high pressure shifts east of our area into Thursday, however there may be a weak low pressure sliding across northern New England Thursday. An associated weak cold front may settle south across our area Thursday afternoon and Thursday. As the ridge aloft arrives Friday, surface high pressure centered well to or north-northeast is forecast to extend southward into our area keeping a front to our southwest.
Our sensible weather through this time frame may be limited to some times of more cloudiness as the system moving through is on the weak side and moisture looks limited. A warm air mass will be in place Thursday, however light enough flow should keep it much cooler closer to the coast with a sea breeze circulation. In the wake of the weak system, some cooling is forecast for Friday although daytime temperatures are still above average. Even on Friday, temperatures will be much cooler closer to the coast once again with more of a marine influence.
LONG TERM /SATURDAY THROUGH TUESDAY/
Summary...Much cooler over the weekend with increasing chances for showers, then turning warmer early next week.
Synoptic Overview...An upper-level ridge axis should be shifting to our east or weakening Saturday. An upper-level trough sliding across the Midwest is forecast to shift east and especially northeast through the weekend into early next week. A cold front attached to the associated surface low should be slow to arrive into our area over the weekend as the main system tracks well to our northwest and north. The front itself may not settle east and south of our area until sometime Monday. This may result in a period of more unsettled weather.
For Saturday and Sunday...As an upper-level trough slides across south-central Canada to the Midwest, it mostly shifts east-northeast more into Canada. A surface low associated with it then tracks well north of our region across Canada. An attached cold front however will slowly be approaching our area during this time frame. Given how far removed the main trough is from the surface cold front, the front should be slow to get into our area. A lead shortwave trough however may provide enough lift for some increase in showers later Saturday through Sunday. The amount of shower activity that occurs with this system is less certain at this time as it will depend on the forcing strength that arrives. Surface high pressure centered to our northeast Saturday before shifting farther east will keep an onshore wind in place and therefore a much cooler air mass across our entire region. The marine influence should also limit the amount of instability.
For Monday and Tuesday...The aforementioned upper-level trough across mostly eastern Canada shifts eastward with more of a zonal flow aloft across our region. Weak high pressure is forecast to be working its way into our area as a weakening cold front settles south and east of our area. This time frame could be precipitation free, however given some timing uncertainty with the front went with the NBM PoPs (20-40 percent). An offshore wind to start should turn more southerly with time and therefore allowing temperatures to warm quite a bit. Some cooling may still occur however along the coast as the wind becomes more off the ocean again.
AVIATION /20Z TUESDAY THROUGH SUNDAY/
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.
Through tonight...Showers and a few thunderstorms are expected to progress from west to east. The storms could start as early as 21-22Z around ABE/RDG, but more likely near or after 00Z for most of our region, possibly down to I-95. Have not carried mention of TEMPO TSRA outside of ABE and RDG, as activity will likely weaken toward sunset, with more stable air across NJ. Once showers and storms decrease in coverage between 03 and 06Z, CIGs may lower to MVFR toward morning, mainly north of PHL toward TTN and ABE. Winds tending light NE, or variable at times.
Low confidence.
Wednesday...Some MVFR or at least low VFR CIGs possible in the morning, particularly from PHL northeastward. Some light SHRA possible around ACY early in the morning, otherwise mainly VFR with partial clearing from west to east heading past 15-18Z.
Winds will become more WNW toward the afternoon from I-95 northwest, but remain E or SE toward the coast, around 4-8 kt.
Moderate confidence.
Outlook...
Wednesday night through Friday...Mainly VFR.
Saturday and Sunday...Sub-VFR conditions probable with increasing chances for showers.
MARINE
Winds and seas are mostly expected to stay below Small Craft Advisory criteria through Wednesday. However, In the Atlantic Coastal waters of South Jersey and Delaware, seas could briefly build near 5 ft as southwest winds pick up to 15-20 kt with some occasional gusts near 25 kt for a few hours through this evening. This seems brief and localized enough so that a SCA doesn't seem warranted. Winds easing and tending more northerly later tonight, then becoming onshore and generally SE around 10 kt on Wednesday, with seas around 3 ft.
Outlook...
Wednesday night through Sunday...The conditions are anticipated to be below Small Craft Advisory criteria, although seas could build to 5 feet for a time Saturday night and Sunday on the ocean zones.
