Synopsis for the coastal waters from sandy hook nj to fenwick island de and for delaware bay - Low pressure moves up toward nova scotia early this morning as cold front moves off the coast, then high pressure briefly builds in later today. A weak clipper system passes through late on Saturday with drying expected on Sunday. An area of low pressure will develop over the central plains on Monday with a warm front extending east into the mid- atlantic. This will lead to unsettled conditions through at least the middle portion of next week before drying out on Thursday.

SYNOPSIS
Low pressure moves up toward Nova Scotia early this morning as cold front moves off the coast, then high pressure briefly builds in later today. A weak clipper system passes through late on Saturday with drying expected on Sunday. An area of low pressure will develop over the Central Plains on Monday with a warm front extending east into the Mid- Atlantic. This will lead to unsettled conditions through at least the middle portion of next week before drying out on Thursday.
NEAR TERM /THROUGH TONIGHT/
A sunny, but dry and windy day is expected.
Longwave troughing will push offshore as ridging builds to our west.
High pressure will build to our southwest today as strengthening low pressure pushes toward Nova Scotia. Cold advection will be underway much of the daytime period. THis combined with a modest pressure gradient will result in deep efficient boundary layer mixing. The result will be a dry and windy day. Northwest winds will increase later this morning to around 15-20 mph with gusts near 30 mph. Some peak gusts near 35 mph are possible across the higher elevations and near the coast. Temperatures will climb well into the mid to upper 50s by this afternoon, though the dry wind will make it feel a bit chilly despite the plentiful sunshine.
The winds will diminish this evening and shift more westerly as boundary layer mixing wanes. There will be a persistent gradient wind overnight near 10-15 mph though. This gradient and the winds will prevent much radiational cooling despite the very dry airmass and dewpoints in the 20s. We should see low temperatures mainly in the mid to upper 30s under clear skies.
SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/
The forecast for the weekend remains largely unchanged, with some showers producing light rainfall on Saturday, followed by a dry and milder day on Sunday. With weak ridging extending northward across the Mid-Atlantic briefly Saturday morning, with high pressure centered near Florida, we will see some sunshine and fairly cool temperatures in the morning, warming well into the 50s toward midday. Some low 60s will be possible around southern NJ into the Delmarva. Model guidance continues to hone in on a weak area of low pressure tracking across PA from the lower Great Lakes, associated with a weak shortwave trough.
Models differ on the exact location and extent of shower activity, but the consensus favors up to a tenth of an inch of rainfall, mainly in the afternoon, with the 'higher' amounts across SE PA. Showers will taper off as the low passes offshore Saturday evening. That will be followed by a fairly mild night as some clouds and a westerly breeze keeps lows in the 40s. Mid and upper-level ridging will expand eastward from the central US to the East Coast on Sunday, and combined with a northwesterly downsloping breeze off the Appalachians and partial sunshine, highs in the 60s will result. Sunday may be the nicest day of the entire forecast period through next week. Clouds will thicken Sunday night with a 30-60 percent chance of showers after midnight, especially south of ABE to TTN.
LONG TERM /MONDAY THROUGH THURSDAY/
An extended period of fairly cloudy, wet weather will commence for the start of the new week, though Monday does not look like a complete washout. Strong low pressure lifting out of the Plains ahead of an upper-low ejecting out of the Southwestern US will be the main cause of our wet weather for the week ahead.
Initially on Monday though, a weaker wave of low pressure tracking along the tightening baroclinic zone extending eastward from the stronger low will be the main forcing mechanism for wet weather here. That should result in only periodic, relatively light rainfall, and portions of the area may just have a cloudy, occasionally drizzly day, depending on exactly where the stronger forcing sets up near the tightening baroclinic zone. Temperatures will remain mild, but cooler than Sunday, with mainly 50s for highs.
Heading into later Monday night and Tuesday, as strong low pressure heads for the lower Great Lakes or the Ohio Valley, a warm front will attempt to lift northward through our region, with strong isentropic lift and some steadier, heavier rain.
Guidance disagrees how far north that front will make it, before a coastal low develops near or region heading into Wednesday.
That is clear from the wide spread in NBM temperature guidance at PHL on Tuesday, ranging from the low 50s to mid 60s for the 25th to 75th percentile high temperatures.
Enough instability, at least of the elevated kind, may be present for some rumbles of thunder Tuesday afternoon through Tuesday night, particularly across the Delmarva where the warm sector is most likely to make it through. Once the coastal low takes over and tracks northeastward toward southern New England on Wednesday, rain will become more showery, as the low wraps colder and drier air into our region. Rainfall amounts from the Monday through Wednesday timeframe look to be around 1.5 to 2 inches or so on average, but with that falling over an extended period of time, the threat of flooding may be limited. Still, Tuesday and Wednesday will bear watching as we get closer, particularly if the rainfall turns more convective. Thursday should turn drier, cooler and windy as potentially intense low pressure wraps up off the New England coast, with perhaps still some clouds and showers toward the Appalachians. The airmass may turn cold enough even for some wet snow showers around the Poconos.
AVIATION /07Z FRIDAY THROUGH TUESDAY/
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.
Through 12Z...VFR with clearing skies. Northwest winds 10-15 kts with some gusts near 20 kts possible at times. North to northwest winds near 2kft increasing to 35-40 kts may lead to some LLWS, especially where gusty winds do not develop at the surface. High confidence on prevailing conditions.
Today...VFR. Northwest winds increasing to 15-20 kts with gusts near 25-30 kts. High confidence.
Tonight...VFR/SKC. Winds diminishing by 00Z and shifting more westerly for the overnight period near 10-15 kts. High confidence.
Outlook...
Saturday: Mainly VFR, with brief MVFR possible with some scattered showers.
Sunday: VFR.
Monday: Chance of rain, Sub- VFR conditions possible.
Tuesday: Rain likely with MVFR or IFR conditions.
MARINE
North to northwest winds will continue to increase through dawn to around 20-25 kts with wind gusts near 30-35 kts forecast. Seas will also increase to around 4-7 feet. Will keep the Gale Warning in effect through this morning for all Atlantic and Delaware Bay coastal waters. A Small Craft Advisory will be needed following the Gale Warning through the remainder of today and perhaps even through tonight as gusts will remain near 20-25 kts and seas near 4-5 feet.
Outlook...
Small Craft Advisory conditions may linger into Saturday morning over the ocean with some leftover 5 ft seas and WNW gusts 20-25 kt. Otherwise expect generally W to SW winds 10-15 kt later Saturday tending WNW on Sunday, with seas in the 2-4 ft range.
Some showers will be possible late Saturday, otherwise expect relatively fair weather, with a pleasant day on Sunday. A warm front will bring increasing chances for rain and lower VSBY on Monday and especially Tuesday into Wednesday. Winds Monday and Tuesday turn easterly 10-15 G 20 kt, potentially stronger on Wednesday as a coastal low develops and lifts northeastward. SCA conditions possible late Tuesday into Wednesday, and possibly a period of gales mid to late week, especially in the wake of that coastal low.
FIRE WEATHER
While soils remain saturated from recent rains, gusty northwest winds near 15-20 mph will develop today along with relative humidity values dropping to near 25-30% across much of the area.
These conditions may result in an increased risk of fire spread, especially this afternoon. Lighter winds near 10-15 mph, relative humidity near 35-40%, and a chance of light rain are forecast for Saturday.
PHI WATCHES/WARNINGS/ADVISORIES
PA...None.
NJ...None.
DE...None.
MD...None.
MARINE...Gale Warning until 10 AM EDT this morning for ANZ430-431- 450>455.
