Area Forecast Discussion National Weather Service New York NY 402 PM EDT Fri Sep 25 2020

SYNOPSIS.

Remnants of Beta is expected to pass south of Long Island Saturday as an upper level shortwave moves through southern New York. Weak high pressure based in the Western Atlantic will remain across the region Sunday through Monday. Meanwhile, a very weak low pressure system will be passing offshore. A cold front approaches Monday night into Tuesday, moving in Tuesday and across the area late Tuesday night into Wednesday. The front may slow down and stall near the region Wednesday night into Thursday with a greater push of the front offshore by next Friday.

NEAR TERM /UNTIL 6 AM SATURDAY MORNING/.

Trough over the Mid-Atlantic promotes south winds which bring moisture from the remnants of Beta locally into Long Island and southern Connecticut. Could see a situation tonight similar to last night where after midnight patchy fog should form initially in the interior portions of Long Island and along the Connecticut coast then gradually spread throughout the forecast area. Over head clouds may hold dense fog at bay but with dew points in the low 60s the possibility can not be ruled out. Ambient temperatures hover in the low 60s as well prior to sunrise. Any fog that does form should begin to dissipate shortly after sunrise between 12-15Z.

SHORT TERM /6 AM SATURDAY MORNING THROUGH SATURDAY NIGHT/.

Cloudy day expected Saturday mainly stemming from the outer low moisture level from Beta. This main plume of moisture enters the area early to mid Saturday as a warm front. Precipitable water values increase to around 1.5 inches meaning there's a slight chance of rain from isentropic showers throughout the day. In the afternoon temperatures should reach the low to mid 70s despite the cloud cover.

Clouds remain into the overnight hours and with the elevated moisture could see another round of patchy fog in the overnight. Temperatures overnight will be slightly higher than the previous night in the mid 60s to start the day.

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

LONG TERM /SUNDAY THROUGH FRIDAY/.

Ridge based well out into Western Atlantic across the region with high surface at the surface to close out the weekend and into Monday. A weak shortwave in combination with a very weak low passing offshore will make for some isolated to scattered rain shower activity Sunday through Sunday Night. The higher PVA and strongest dynamics move across Monday.

Shortwave and strongest dynamics pass east of the region Monday night into early Tuesday before another longer shortwave associated with the cold front approach. Strongest dynamics with the front and trough aloft move in Tuesday night into Wednesday. On the larger scale, a large trough in the upper levels remains across the Ohio and Tennessee Valleys mid to late in the week. The result at the surface will be a slower progression of the front, with it lingering near the region Wednesday into Thursday. Stronger positive vorticity advection heading into next Friday with a deeper trough will push the front farther offshore.

In terms of weather, showers remain in the forecast through much of the long term. Likely POPS Tuesday night into Wednesday morning show when the strongest dynamics with cold front moving across from a model consensus. However, models do exhibit quite a difference in surface and mid level height fields and associated surface precipitation with vast differences in timing between the ECMWF and the GFS.

Temperatures overall are forecast to be several degrees above normal Sunday through Tuesday and closer to normal thereafter.

AVIATION /20Z FRIDAY THROUGH WEDNESDAY/. High pressure will remain over the Atlantic through Saturday. Meanwhile, a dissipating low will move off the mid-atlantic coast.

Mainly VFR today. S-SW flow around 5-10 kt are expected this afternoon. KEWR/KTEB should shift SE late afternoon, with speeds at KJFK around 10 kt.

Patchy IFR fog is possible tonight, mainly across the outlying terminals. NYC terminals could see some conditions fall to MVFR. CIGs in the 3-4k ft range move in towards daybreak on Sat, and are expected to lower closer to 2 kft closer 14z.

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

Moderate confidence on winds today. Uncertainty on Saturday with respect to how low the cigs will be.

OUTLOOK FOR 18Z SATURDAY THROUGH TUESDAY. Saturday through Sunday. Chance of late night/early morning fog with IFR conditions. VFR/MVFR cigs expected. Sunday night. Chance of MVFR conditions with any showers late. Monday and Tuesday. Chance of MVFR conditions with any showers or isolated afternoon tstms. S-SW winds G20-25kt. Wednesday. Mainly VFR.

MARINE.

Light southwest winds 5-10kts through the near term with waves 2 to 3 feet. Winds pick up slightly over the ocean waters Sunday as the remnant low of Beta moves south of Long Island.

SCA level winds forecast across mainly the ocean with the cold front passage Tuesday night into early Wednesday. SCA levels seas on the ocean Tuesday night through Thursday.

HYDROLOGY. No hydrologic impacts are anticipated at this time through the forecast period.
