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 TONIGHT/
Showers continue to decrease in coverage. With the marine layer advecting in and typical nocturnal temperature trends, instability is now extremely limited, so don't expect to see any more thunderstorms. What showers remain will gradually progress eastward off the coast near or shortly after sunrise.
Once this round of showers progresses off the coast, the rest of the day should be dry. As mentioned by the previous shift, the training upper level trough will still be crossing our region through the day, but with very limited moisture, do not expect it to result in any additional rain.
In the wake of Tuesday's front, temperatures will generally be a bit cooler today - in the 70s for most of the region. A developing sea breeze by mid day will only help to reinforce this for the coastal plains.
Overnight, as the surface high sits just east of our region, expect more widespread onshore flow to develop. The main implication for this will be either fog or low stratus especially for the coastal plains as the marine layer advects in. At this point, most model soundings show fog more likely than low stratus, but given the complexities of this setup, I don't have very high confidence one way or the other.
SHORT TERM /THURSDAY 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 /06Z WEDNESDAY THROUGH SUNDAY/
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.
Through 12Z...Main aviation impacts at this point are fog potential in the Lehigh Valley (including KABE), and low marine stratus that has already lowered ceilings at times at KACY. The marine stratus may also affect KMIV, KPNE, KPHL, and KILG by 12Z, but as we've already seen at KACY, it may be transient at times. Winds tending light NE, or variable at times. Low confidence.
Today...Any morning fog or low stratus should dissipate by 15Z, leaving VFR conditions for the remainder of the day. Expect winds to settle out of the NW for a period, but a developing seabreeze should switch winds around to southeasterly at KACY, KMIV and possibly as far west as KILG, KPHL, and KPNE. Moderate confidence.
Tonight...Starting VFR, but expect southeasterly onshore flow to result in either fog or low clouds at KACY, KMIV and possibly the 95 corridor TAF sites after 06Z. Winds predominantly southeasterly at 5 kt or less, though direction may be variable, especially at KRDG and KABE.
Outlook...
Thursday through Friday...Mainly VFR.
Saturday and Sunday...Sub-VFR conditions probable with increasing chances for showers.
MARINE
Winds and seas are expected to stay below Small Craft Advisory criteria through Wednesday. 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.
