Area Forecast Discussion National Weather Service New York NY 1138 AM EDT Fri Aug 14 2020

SYNOPSIS. A frontal boundary remains nearly stationary south of Long Island into this evening. High pressure then takes control on Saturday and weakens on Sunday as low pressure approaches from the Mid- Atlantic. The low passes to our south on Monday and is followed by a cold front late Monday night into Tuesday morning. High pressure regains control thereafter into the mid-week period.

NEAR TERM /UNTIL 6 PM THIS EVENING/. High pressure continues to build across New England as a cold front remains stationary south of Long Island. NE flow will usher in some drier low level air. At the same time, a wave of low pressure passes to our south along a stalled frontal boundary.

Have updated to remove PoPs through the day as subsidence to the north of the low pressure and from the high ridging down into the area will prevent any showers. Have also raised high temperatures a few degrees on Long Island based on current trends. Highs may be reach in the next 1-2 hours, in the middle 80s, before E-SE flow develops leveling off any temperature rise. Overall highs across the area will be near seasonable in the low to mid 80s.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SATURDAY/. Drying in the low to mid levels will promote a dry night tonight as high pressure attempts to build in from the north, but is hampered by a wave of low pressure passing by to our south. The combination of these two features will lead to somewhat breezy conditions on Saturday, particularly for coastal areas. This NE-E flow and increasing afternoon clouds will also hold high temperatures into the 70s for some coastal spots. High temperatures otherwise near normal away from the coast. Models hint at a low chance of showers over SE CT and the Twin Forks area, so will include a slight chance of a shower here in the afternoon.

There is a moderate risk of rip currents on Saturday.

LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/. Focus shifts towards an approaching shortwave trough exiting the Ohio River Valley. Mid-level moisture returns to southern New York as this system approaches. Winds veer slightly and precipitable water values increase to around 2 inches. Models are indicating possible enhanced isentropic lift along the warm front late Sunday. Total QPF from these showers and possible thunderstorms is hard to pin down as amounts will be highly contingent on the location of the heavy rainfall axis. At the moment models are keeping the heaviest rainfall south of Long Island. However if the system drifts north rain amounts ranging between 1 to 2 inches total across southern New York, northeast New Jersey and southern Connecticut are not out of the questions. This means isolated flash flooding will again be possible late this weekend. Areas not affected by rainfall will see cloudy skies and temperatures in the upper 70s.

The primary longwave trough over the Great Lakes Region pivots through New York early next week. This dynamic lift from this trough may induce additional showers to start the week, but precipitable water values hover around 1.4 to 1.5 inches. Any showers in this environment should be light to moderate. As the trough axis exits New England mid week, locally long range models are depicting some slight surface ridge from a possible 1017 mb high above Pennsylvania. Subsidence should keep rain chances to a minimum but uncertainty still exists whether or not this holds through Thursday. More confidence in high temperatures which should persist in the low 80s through the week.

AVIATION /16Z FRIDAY THROUGH TUESDAY/. VFR as the area remains between high pressure building to the north and low pressure passing well to the south.

Winds NE-E under 10 kt at most inland sites, and around or just over 10 kt along the coast. Winds should back more NE and diminish to under 10 kt this evening.

OUTLOOK FOR 12Z SATURDAY THROUGH WEDNESDAY. Saturday. VFR. E winds 10-15G20kt. Saturday night through Monday. MVFR or lower in any showers/tstms. Tuesday and Wednesday. VFR.

MARINE. Increasing E flow should bring SCA conds to the ocean waters from late evening through at least Sat night as low pressure passes to the south and high pressure builds to the north. Wind gusts should peak just over 30 kt E of Fire Island Inlet daytime Sat, while sea peak at 6-8 ft.

Lingering marginal SCA conds likely on Sunday as E flow persists. Sub SCA conds may return Sunday night/Monday but this remains uncertain. Sub SCA conditions with light west winds 5-10 kts otherwise begin Tuesday before shifting south by the middle of the week.

HYDROLOGY. No hydrologic impacts are expected through Saturday.

Precipitable water values could be around 2 inches Sunday into Monday as a warm front with heavy rain moves slowly over southern New York. QPF values between 1 to 2 inches with isolated higher amounts are not out of the question. Nuisance to minor flooding could be possible in any showers and thunderstorms, primarily in urban and other poor drainage areas.
