Area Forecast Discussion National Weather Service New York NY 742 AM EDT Thu Sep 24 2020

SYNOPSIS. High pressure will remain off the mid-Atlantic coast through Friday. A disturbance will pass to the south on Saturday. A cold frontal passage will then occur early next week.

NEAR TERM /UNTIL 6 PM THIS EVENING/. Forecast is on track with only minor changes made to reflect current conditions. Cirrus continues to move in from the west with partly to mostly cloudy skies.

Surface high pressure will be off the mid-Atlantic coast today, meanwhile, there will be zonal flow aloft. Two shortwaves approach, one from the northern stream and one from the southern stream. However, they will remain to the west of the area today.

High clouds well out ahead of the remnants of Beta will continue to make their way into the area today. This may keep temperatures a degree or cooler than yesterday. Expect highs in the upper 70s to around 80.

There is a moderate risk of rip currents at the Atlantic Ocean beaches today due to a lingering E-SE swell and onshore winds this afternoon.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/. The high will remain offshore and then build back into the area somewhat on Friday. The upper level shortwaves continue to approach the area tonight into Friday, but northern stream one will weaken, while the southern stream will remain to our southwest. So, dry conditions are expected through this time frame.

As for temperatures, the presence of clouds will prevent temperatures from dropping too much tonight, though with less in the way of coverage for the interior, these areas do have the potential to be colder than is currently forecast. The rest of the forecast area will be a few degrees above normal. Lows will range from the 50s to lower 60s. Highs on Friday will be similar to Thursday.

Thursday and Thursday night a northern stream shortwave begins to phase with a southern stream shortwave that will be moving into the mid Atlantic region. Both of the waves are very weak, broad, and low amplitude. And at the lower levels this waves nearly washout as they move into surface ridging. In addition, there is little moisture, so expect dry conditions, with mainly high cloudiness.

There is a low to moderate risk of rip currents at the Atlantic Ocean beaches on Friday due to a lingering E-SE swell.

LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/. A weak area or surface trough will develop over the mid-Atlantic late Friday night as the southern stream shortwave approaches the mid-Atlantic coast. Both these features are expected to pass south of the region Saturday. However, the NAM and the Canadian do bring in some light showers. This may be overdone, especially with the high building back into the area, however, a passing shower cannot be ruled out for Saturday and the first part of Saturday night. Dry conditions then expected for the remainder of the weekend.

Models seem to be hinting at some increased low level moisture late Friday night into early Saturday morning across Connecticut and Long Island, so added some patch fog for these areas.

An H5 trof drops down into the Midwest on Mon. This opens the area up to strong sw flow aloft. There could be a few shwrs in this flow Sun ngt into Mon, but the best chance for organized activity looks to be closer to the cold front. That timing is late Mon and Mon ngt. Pops capped at 30 due to concerns over timing this far out.

Depending on how the upr lvl trof sets up, there could be some instability related shwrs Tue into Wed. Another chance of shwrs then follows for mid week with another cold frontal passage.

The NBM with local adjustments was used for temps in the extended. A persistent sly llvl flow will keep readings abv normal for most of the period. The second cold frontal passage during the middle of next week will likely produce a cool down to temps aob climo.

There is a moderate risk of rip currents at the Atlantic Ocean beaches on Friday.

AVIATION /12Z THURSDAY THROUGH MONDAY/. High pressure over the Mid Atlantic passes to the south today.

VFR.

Light W-NW winds early will veer to the SW with coastal seabreezes developing from late morning into the afternoon. KEWR, KTEB, and KHPN seabreezes will be later in the day around 21Z to 22Z.

. NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty .

Wind shift to the SW and seabreeze timing may vary by 1 to 2 hours.

OUTLOOK FOR 12Z FRIDAY THROUGH MONDAY. Friday. VFR. Saturday. Chance of MVFR conds with any showers. Sunday. MVFR conds possible AM. Monday. Chance of MVFR conds with any showers or isolated tstms. S-SW winds G20-25kt.

Detailed information, including hourly TAF wind component forecasts, can be found at: http:/www.weather.gov/zny/n90

MARINE. Light winds through the weekend will keep seas below 5 ft through the weekend.

SCA likely for Mon. The protected waters look to remain blw sca lvls thru Mon. There could be a period where the ocean goes blw SCA lvls on Tue, then S winds kick in again on Wed.

HYDROLOGY. No hydrologic impacts are anticipated through next Wednesday.
