Synopsis for the coastal waters from sandy hook nj to fenwick island de and for delaware bay - An area of low pressure will remain offshore of the middle atlantic coast today before drifting out to sea. Another area of low pressure moves across the central appalachians and offshore of the north carolina coast over the weekend. High pressure appears to finally build across the area early next week, before a cold front arrives toward the latter part of the week.

SYNOPSIS
An area of low pressure will remain offshore of the Middle Atlantic coast today before drifting out to sea. Another area of low pressure moves across the central Appalachians and offshore of the North Carolina coast over the weekend. High pressure appears to finally build across the area early next week, before a cold front arrives toward the latter part of the week.

NEAR TERM /THROUGH TONIGHT/
As the low shifts further off shore, starting to see some gradual improvement both in terms of the drizzle coming to an end, and the lower clouds scattering out.

Today will be a nice break in the dreary and rainy conditions we've seen the last few days (and what we'll see again tomorrow). With weak mid level short wave ridge in place, should have dry conditions with some breaks in the clouds, especially during the later half of the day. Even in areas where there are breaks in the clouds, it will be offset by the persistent onshore flow, thus resulting in temperatures near normal, with highs ranging from the upper 60s to mid 70s.

Clouds start building in again tonight as the next mid level trough begins to approach from the southwest. Rain showers associated with this system may start to encroach on our region before sunrise, especially for portions of Delmarva and areas of SE PA. Rain amounts should be light though.

SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/
Approaching upper trough and surface low will spread a risk of showers into the region from the west on Saturday, along with plenty of clouds, but instability will be weak to non-existant with lingering marine influence and weak upper forcing, so don't expect any thunder of significance, and showers will generally be dwindling as they work eastward across the CWA as the upper trough washes out and the bulk of the energy stays south. Highs mostly in the 60s.

Surface high pressure nudges southward back into the area on Saturday night and Sunday, with most energy now completely confined to the south of the area, so this should help completely end rain chances. However, lingering low-level moisture may keep some patchy fog/drizzle/low clouds around, especially at night into early Sunday. By Sunday afernoon, do expect at least some breaks of sun, if not a partly to mostly sunny afternoon. After lows mostly in the 50s, highs rebound into the lower 70s, but cooler near the water with lingering onshore flow.

High pressure builds a bit stronger southwestward Sunday night, potentially clearing out some more low clouds, but opening a better window for patchy fog development. Otherwise, quiet with lows again mostly in the 50s.

LONG TERM /MONDAY THROUGH THURSDAY/
Several days of mostly dry and mostly sunny weather are looking increasingly likely with near to slightly above normal temps as we start the next work week as high pressure tries to hold firm for several days. This should help keep any precip away, with temps rising well into the 70s to near 80 during the daylight hours. Lows will remain in the 50s Monday and Tuesday nights thanks to mostly clear skies and light winds under the high.
Can't rule out patchy fog but won't include in forecast yet.

By Wednesday night into Thursday, clouds and southwesterly flow will increase ahead of the next cold front. This will bring a chance of showers and thunderstorms by Thursday but still temps near 80 after a night where temps may not fall below 60 for many.

AVIATION /08Z FRIDAY THROUGH TUESDAY/
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas...

Through today...Expect gradual improvement in ceilings through the morning. Current trends have been faster than almost all guidance in improving conditions, so have reflected this in the TAFs. Based on these trends, all TAF sites are likely to return to VFR before 18Z, with KACY likely being the slowest to return to VFR. Wind speeds 5 to 15 kt through the day. The direction will be starting from the NNE, but should be out of the SE by late today for most TAF sites; KACY could remain NE through the TAF period. Moderate confidence on the overall pattern, but low confidence on exact timing of improvement.

Tonight...Starting VFR, but after 06Z, could see ceilings and visibilities reduced to MVFR in rain showers. TAF sites most likely to see the reductions before sunrise are KILG and KRDG.
Wind speeds should drop to 5 kt or less overnight. As for wind direction, winds may go light and variable for a period, but should generally favor the easterly direction. Moderate confidence.

Outlook...
Saturday and Saturday night...MVFR/IFR with chance SHRA and patchy BR.

Sunday...MVFR possible early with patchy BR, then mainly VFR.

Sunday Night: Mainly VFR, with MVFR possible due to patchy BR.

Monday...MVFR possible early due to patchy BR, improving to VFR.

Monday night and Tuesday...VFR.

MARINE
For the Atlantic coastal waters, expect elevated seas to gradually diminish through the day. Once they do, expect winds and seas to remain below Small Craft Advisory criteria through tonight.

On the Delaware Bay, winds and seas will remain below SCA criteria through tonight.

Outlook...
Saturday through Tuesday: Sub-SCA with winds less than 15 kts and wave heights less than 5 feet. Chance of showers Saturday into early Sunday, otherwise no significant weather.

PHI WATCHES/WARNINGS/ADVISORIES
PA...None.
NJ...High Risk for Rip Currents through this evening for NJZ014-026.
DE...None.
MD...None.
MARINE...Small Craft Advisory until 6 PM EDT this evening for ANZ450>455.
