SYNOPSIS. Light rain moves off the coast today as high pressure builds in over the Mid-Altantic and New England states. High pressure will weaken slightly before reestablishing itself across the Appalachian mountains early in the week.

NEAR TERM /UNTIL 6 PM THIS EVENING/. Small changes to ongoing forecast with drier and cooler air arriving across the region. Slowly decreasing low/mid clouds and plenty of high cloudiness for the daytime hours. North to northeast winds gusting to around 20 mph at times. Minor temps and dew point changes made.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SATURDAY/. Cold air advection continues this evening with high pressure over the region. Anticipate our first "chilly" night of the Fall with the potential of some frost formation over portions of the Poconos. Lows will be in the mid to low 40s with mid 30s expected for the Poconos. Some light patchy frost may develop over portions of Carbon and Monroe county in PA but isn't widespread enough to warrant justification for a full county advisory.

Saturday should be a pleasant albeit "chilly" day with highs in the low to mid 60s and modest gusts up to 20 mph out of the north.

LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/. Dry weather continues through the weekend with high pressure cresting to the north and east. Winds should be gusty as times as a modest pressure gradient force remains in place with high pressure located over the Great Lakes and low pressure to our south. Northerly winds should weaken during the overnight hours allowing for modest longwave radiational cooling through at least Monday night.

Heading towards the middle of the week, the high pressure system starts to sag south over the Appalachian region with an upper level trough digging into New England. This could be enough to cause some spotty showers if any shortwave are able to track this far south but will be highly dependent on available moisture. As of the 00z suite, the forecast remains dry through late Thursday with only a 15- 20% chance of showers for the northern tier of the forecast area.

AVIATION /16Z FRIDAY THROUGH TUESDAY/. The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.

Today . VFR/MVFR ceilings, improving to VFR/SKC in the afternoon. North wind 10 to 15 knots with gusts around 20 knots. High confidence.

Tonight . VFR conditions expected with north to northeasterly winds 8-12kts.

Outlook .

Saturday-Saturday night . VFR conditions expected. North to northeast winds may gust around 15-20 knots at times. High confidence.

Sunday-Sunday night . Mostly VFR conditions expected. Northeast winds may gust 15-20 knots at times. High confidence.

Monday-Tuesday . Generally VFR conditions expected. Northeast Monday, become north to northwest Monday night into Tuesday. Winds may gust around 15-20 knots at times. Moderate confidence.

MARINE. Small Craft Advisory begins at 6 AM as northeast winds will ramp up to 20 to 25 with gusts of 25 to 30 knots and seas build to 5 to 8 feet by later today into tonight.

OUTLOOK .

Saturday through Saturday night . The Small Craft Advisory continues through this period as northeast winds continue generally at 15 to 25 with gusts of 25 to 30 knots. Seas continue in the 5 to 8 foot range.

Sunday through Tuesday . Extended period of Small Craft Advisory conditions likely to continue due to persistent northeast winds. Seas may build as high as 10 feet by Monday due to swell from Hurricane Teddy

RIP CURRENTS .

There is an enhanced risk for the development of dangerous rip currents for today right into the early part of the new week as a strong north to northeast wind and rough seas develop along the coast. For today, we've issued a High Rip current risk for the Delaware Beaches as there will be a strong onshore component to the swell as it's directed against the shore from the northeast.

TIDES/COASTAL FLOODING. The new moon was yesterday (Thursday), so astronomical tides will continue to be higher than normal for the next couple days.

For the Atlantic coast: As the flow shifts to northeasterly this morning, surge above the astronomical tide should gradually increase. The high tide this morning should be relatively unaffected as the wind shift will be mostly coming too late to affect those high tides (though spotty minor flooding is possible around high tide). However, beyond this time widespread minor flooding becomes increasingly likely so we've issued a Coastal Flood Advisory that starts this evening for most counties (exception being Middlesex County) and continues through midday Saturday to account for the Saturday morning high tide as well. Can't rule out a few spots mainly south of Barnegat Bay getting close to or just touching Moderate flooding levels with the Saturday morning high tide but this is not the most likely scenario so a Coastal Flood Watch or Warning is not warranted at this time.

For the Delaware Bay and tidal Delaware River: The wind direction is less likely to lead to tidal flooding (as opposed to an E or SE direction). The one exception is along the southern shores of the Delaware Bay (primarily along the bay shores in Kent and Sussex County DE), where we've issued a Coastal Flood Advisory that also begins with this evening's high tide.

For the Northeast Chesapeake Bay: Despite higher astronomical tides, tidal flooding is not expected at this time as the NNE wind direction does not typically lead to water being slow to evacuate the bay.

PHI WATCHES/WARNINGS/ADVISORIES. PA . None. NJ . Coastal Flood Advisory from 8 PM this evening to 2 PM EDT Saturday for NJZ013-014-020-022>027. Coastal Flood Advisory from 8 AM to 2 PM EDT Saturday for NJZ012. DE . Coastal Flood Advisory from 8 PM this evening to 2 PM EDT Saturday for DEZ002>004. High Rip Current Risk through this evening for DEZ004. MD . None. MARINE . Small Craft Advisory until 6 AM EDT Sunday for ANZ430-431- 450>455.
