Synopsis for the tidal potomac and md portion of the chesapeake bay -
low pressure and its associated cold front will push offshore today as weak high pressure builds over the waters from the south. Additional waves of low pressure and slow-moving fronts will pass through the region late Friday into the weekend. Weak high pressure will briefly return to the waters Monday and Tuesday before another low pressure system impacts the waters midweek. Small craft advisories may be needed for portions of the waters Saturday and Sunday.

SYNOPSIS
An area of low pressure will remain offshore of the Mid Atlantic coast through Friday, before drifting out to sea. High pressure tries to build down into the area from the northeast over the weekend. Another area of low pressure moves across the central Appalachians and offshore of the North Carolina coast later Sunday into Sunday night. Weak high pressure may finally build across the area early next week, before a cold front moves across the east coast by mid week.
NEAR TERM /THROUGH TONIGHT/
1025 AM...The slow moving surface low lingering off the NJ coast has started to drift a bit farther south and east over the past several hours and this has cause low levels winds to veer from more NW to NNE. Not a big change but enough to cause the cloud deck to lower and expand back to the west a bit farther.
This is also keeping some drizzle going mainly over NJ with some dense fog around Atlantic City. Long story short, we'll have more of the same through today and tonight as the coastal low remains just east of the region, and will stay there especially through the day today. It should eventually start to very slowly drift northeastward away from our region late tonight.
While there will continue to be some additional light rain or drizzle across NJ, especially near the coast, for the rest of the region the main impacts will be continuing cloudy and (relatively) cool conditions. Highs today will be mostly in the 60s to low 70s...warmest west and coolest east.
Later tonight, there is a concern for fog potential. Mid level short wave ridging builds in over the region. This subsidence coming during the overnight hours could result in a nearly saturated boundary layer. However, if low clouds linger into the overnight hours, it could be more of a low stratus event, suppressing much fog development, so have low confidence one way or the other.
SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/
Ocean storm which has plagued us much of the week may help keep things a bit drier during the end of the week and weekend as it lingers off the coast and only crawls further east. This will slow everything down overall but place a weak blocking ridge over our region Friday and Saturday. While not guaranteed, especially down in the Delmarva and further one gets westward into PA, the resulting blocking high may be enough to keep most of the region dry through this time. That said, some guidance still dislodges the ridge enough to bring some showers across the region, starting later Friday night and continuing into Saturday night, but best chances of rain this weekend do appear to be more Saturday than Sunday. That having been said, still a decent chance that areas from Philly north and east, at least, stay pretty much dry through the weekend. Highs will be influenced due to persistent cloud cover (which won't be giving way so easily) and onshore flow, so while we nudge into the 70s with some better breaks of sun on Friday, 60s will be common Saturday again, and with the easterly flow, cut 5-10 degrees off near the coast. Lows will stay seasonable, with low 50s common.
LONG TERM /SUNDAY THROUGH WEDNESDAY/
Next incoming system from the west looks to be shunted south by the slow moving coastal storm which will linger near Atlantic Canada Sunday. Thus, odds of precip Sunday look pretty low now, especially north of Philly, but onshore flow will keep clouds around and temps cool, with highs mostly in the 60s and cooler near the coast.
Upper level ridge then tries building eastward across the region as the aforementioned storm shunted to our south lingers there early next week. Surface high pressure will build over the region as well, so expect some clearing and warming, though at best, temps look likely to return to near normal, as we'll retain a threat of some clouds lingering with the surface high to our north still providing a bit of an onshore gradient. But, at the very least, Monday and Tuesday look quite dry right now.
Things change Wednesday as the next front approaches from the northwest. This will bring a returning threat of showers, maybe even a thunderstorm, but the increased southwesterly flow should help pump temps up a few more degrees, so a few spots especially from Philly south and west might reach 80 or so. Lows thru the end of the weekend into the first half of next week look to be near 50 to mid 50s for much of the region, mildest Tuesday night ahead of the front.
AVIATION /14Z THURSDAY THROUGH MONDAY/
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas...
Today....Lower clouds will linger for much of the day with TAF sites east of PHL seeing mainly MVFR cigs and even IFR/LIFR conditions at times for ACY. Just to the west around PHL north to ABE, cigs will likely continue to hover right near the threshold of low VFR vs. MVFR making for a tricky forecast in terms of flight categories. Meanwhile RDG should stay mainly VFR. Winds that were NNW earlier will continue to shift to more NNE into this afternoon which is helping to bring back the lower cigs, mist/fog, and drizzle. Generally expect winds 10 to 15 gusting 20 to 25 knots. Moderate confidence on the overall pattern, but low confidence on exactly which flight category the ceilings will be in.
Tonight...This evening, expect similar conditions as what is prevailing through the day. However, near or after midnight, if we see any breaks in the clouds, it could be enough for fog to develop, resulting in IFR or lower conditions. That being said, this is dependent on breaks in the low clouds and guidance that depicts fog potential in general appears too aggressive in depicting clearing. Also, it will be very localized if it does develop. Thus, low confidence on it occuring at any one TAF site. NE winds continue, but speeds should diminish to less than 10 kt. Low confidence.
Outlook...
Friday...Mainly MVFR, with local IFR possible. NO SIG WX.
Friday Night-Saturday...VFR/MVFR likely. Chance SHRA.
Saturday Night-Sunday...MVFR/IFR conditions possible. Chance SHRA.
Sunday Night-Monday...VFR likely. NO SIG WX.
MARINE
For the Atlantic coastal waters, expect Small Craft Advisory conditions to continue today and tonight.
On the Delaware Bay, though there may be some gusts around 20 kt, expect them to stay below 25kt, thus, no SCA conditions are anticipated at this time.
Outlook...
Friday...Small Craft Advisory on all NJ and DE adjacent ocean waters with waves of 4-6 feet, subsiding late. Sub-SCA on the Delaware Bay. Wind gusting no higher than 20 kts all waters.
Friday night thru Saturday night...Mainly sub-SCA. Wind gusts to 20 kt. Wave heights generally below 5 feet. Chance SHRA.
Sunday thru Sunday night...SCA conditions possible. Wind gusts to 20 kt. Wave heights up to 5 feet. Slight chance SHRA.
Monday...Mainly sub-SCA. Wind gusts to 20 kt. Wave heights mainly below 5 feet. NO SIG WX.
PHI WATCHES/WARNINGS/ADVISORIES
