.SYNOPSIS... Low pressure over the Atlantic will drift east and away from the region today. A cold frontal passage occurs on Wednesday. High pressure will then build in through the end of the week.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/... Low pres was analyzed about 415 miles S of Montauk at 6Z. There were a few lightning strike over the ocean, as well as invof sern MA, but as the low drifts ewd today, the instability axis should exit the region as well. Moisture and lift confined to the low lvls today, so mainly periods of lgt rain and perhaps dz expected. Although the flow continues to gradually decrease, it will still be breezy with a NE/NNE wind. Best chance for some clearing will be nwrn and wrn zones especially late as drier air advects in on nwly flow aloft. Despite this, much of the cwa is expected to remain ovc thru the day. High temps modeled to be slightly blw climo. With a well mixed llvl flow the NBM was followed.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY NIGHT/... More substantial clearing is expected tngt as NW flow deepens across the region. It may hold off until aft midnight for ern portions of the cwa, where the best chances for lingering lgt rain are in the eve. Once the rain does end, it looks like it remains dry until some time Sun or later. A lgt NW flow may allow for some interior valley fog, but the prob was too low to include in the fcst.
A cold fropa on Wed. Moisture starved so no pcpn has been fcst attm. Some mid and high clouds can be expected. Also some fair wx cu possible as temps hit convective. A nwly breeze will develop facilitated by daytime mixing behind the front. The NBM was followed for temps.
Colder Wed ngt with a new airmass building in. The NBM was followed which brings most of the interior into the 30s. The numbers are not low enough attm for widespread frost however.
&&
.LONG TERM /THURSDAY THROUGH MONDAY/... The long term fcst is on track and the NBM was used.
Key Messages:
* Dry conditions will prevail through Sat ngt. It will remain breezy through Friday due to the pressure gradient between high pressure to the west and low pressure meandering out over the open Atlantic.
* Below normal temperatures will prevail through Friday with highs only in the upper 50s/lower 60s. Nighttime temperatures could fall into the 30s inland and 40s elsewhere.
* Milder weather returns this weekend as a warm front passes to the north and the high builds over and east of the area this weekend. Temperatures should reach the lower 70s by Sunday.
* A cold front will bring showers mainly Sunday night into Monday.

.AVIATION /12Z TUESDAY THROUGH SATURDAY/... A coastal storm pulls away from the area today.
Cigs continue to be right around 1kft. IFR has returned at some terminals, but this is expected to be short-lived. Mainly MVFR cigs are expected through the day. -DZ and BR will be around through the morning potentially bringing vsbys down to MVFR. Some light rain showers may also move through today, but are expected to be isolated and not have an impact on the flight categories. Categories improve to VFR this evening as cigs lift.
North winds hold steady through the day around 10-15G20-25KT with a gradually diminishing wind into the evening. Gusts are expected to end by this evening around 23Z-1Z.
...NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...
Any IFR cigs should be short-lived, but amendments may be needed.
Wind gusts could end up slightly lower than forecast.
.OUTLOOK FOR 12Z WEDNESDAY THROUGH SATURDAY...
Wednesday and Thursday: VFR. NW winds G20-25kt.
Friday: VFR. NW winds G15-20kt.
Saturday: VFR.

.MARINE... A SCA is in effect for all waters today, except for the cntrl/ern ocean where a mrgnl gale remains in effect until noon. Thereafter, a SCA will likely be needed on the ocean all week, possibly coming down on Sat. Elsewhere, a SCA may be needed again behind a cold front Wed, lasting perhaps thru Fri on NW winds.
&&
.HYDROLOGY... No hydrologic impacts expected.
&&
.TIDES/COASTAL FLOODING... No changes were made to the TWL forecast or coastal flood hazards. The overnight into this morning high tide cycle came in a few tenths short of the forecast at some locations, but confidence was not high enough to lower the forecast for the afternoon high tide cycle. If this trend continues, Lindenhurst will likely fall just short of moderate flood levels.
Water levels continue to recede. Coastal Flood Advisory remains in effect for SW Suffolk, where tidal piling on the western Great South Bay should result in more widespread minor and locally moderate flooding with the high tide late this afternoon.
Water levels could also briefly touch minor flood thresholds in spots late this afternoon in S Nassau, also along tidal waterways of NE NJ and Staten Island. High surf up to 7 ft could still produce minor beach erosion on the oceanfront into this morning. Statements issued for these hazards.
As winds and seas both subside, tidal piling will diminish, ending the coastal flood threat thereafter for most places. Couldn`t rule out some brief/spotty flooding on the Great South Bay with the late day Wed high tide cycle.
Forecast is from bias-corrected 12Z PETSS ensemble 50% exceedance based on its performance during the last high tide cycle.
