Area Forecast Discussion National Weather Service New York NY 708 AM EDT Fri Sep 25 2020

SYNOPSIS. High pressure will gradually weaken over the western Atlantic into early next week, while a dissipating area of low pressure moves off the Mid Atlantic coast on Saturday. A slow moving frontal systems will then impact the area from Tuesday into Wednesday.

NEAR TERM /UNTIL 6 PM THIS EVENING/. SPS is in effect for patchy dense fog through 8 am, otherwise minor adjustments made with this update.

The combination of shallow low-level moisture and light winds had allowed for patchy fog (some dense) and low clouds to form across the area, especially near the coast and river valleys. Due to the very shallow nature of the moisture, the fog and any clouds are likely to dissipate quickly after sunrise.

Weak shortwave ridging today ahead of a shortwave trough over the Ohio Valley will allow for a warm day with mostly sunny skies. Highs will top out in the mid 70s to lower 80s, which is about 5 to 8 degrees above normal. Southerly winds will prevail at 5 to 10 mph.

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

SHORT TERM /6 PM THIS EVENING THROUGH SUNDAY NIGHT/. Remnant moisture from Beta will be drawn northward along the Mid Atlantic coast tonight as a shortwave trough moves into the region. Weak lift and deepening moisture will allow for a low chance of showers toward daybreak, mainly near the coast. This chance will spread northward across the remainder of the area Saturday. At this time, rainfall looks to be hit and miss and light with less than a tenth of an inch.

Heights build aloft Saturday night into Sunday ahead an amplifying trough over the Northern Plains. This should keep conditions mainly dry for the second half of the weekend, but unseasonably warm and increasingly humid. Highs will generally be in the mid to upper 70s with lows in the 60s.

Additionally during this time, the onshore flow and lengthening nights will at the very least result in some patchy fog. There is also the mention of patchy drizzle late Saturday night into Sunday morning with some lift advertised in the the low-levels from warm advection.

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

LONG TERM /MONDAY THROUGH THURSDAY/. A pattern transition will then begin to occur into next week. Long wave amplification will take place as heights rise out west, and a trough develops over the Midwest and begins to translate east. Ahead of the front over the Mississippi Valley, warm conveyor belt showers should develop on Monday, and with some instability cannot rule out a thunderstorm. Chances will continue through mid week with the boundary tracking slowly east. Global models differ in the timing of the system with some uncertainty as to whether or not a closed low develops at the base of the trough across the Lower Mississippi Valley. The latter of which could slow down the boundary or stall it close to the area with a series of frontal waves traversing the boundary during the mid week period.

Following the frontal passage on Wednesday (possibly later), temperatures will fall back to near seasonable levels behind a series of cold fronts. Near normal temperatures will last into later Wednesday through the remainder of the week as the long wave trough will be stubborn to push out of the area.

AVIATION /12Z FRIDAY THROUGH TUESDAY/. High pres over the Atlc thru Sat.

Mainly VFR today. Some patchy fog til about 13Z outlying arpts with IFR or lower. Light SW/vrb winds will increase to 5-8 kt after 13Z-14Z, with a more southerly coastal sea breeze in the afternoon. KEWR/KTEB should shift SE late afternoon, with speeds at KJFK around 10 kt.

Patchy IFR tngt due to fog, mainly outlying terminals. NYC arpts could drop to at least MVFR, but confidence is not yet high enough to include in the TAFs. CIGs in the 3-4k ft range on Sat.

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

Amendments possible for fog improvement this mrng. Moderate confidence on winds today.

OUTLOOK FOR 12Z SATURDAY THROUGH TUESDAY. Saturday through Sunday. Chance of late night/early morning fog with IFR conds, otherwise mainly VFR. Sunday night. Chance of MVFR conds with any showers late. Monday and Tuesday. Chance of MVFR conds with any showers or isolated afternoon 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. Winds and seas will remain below SCA levels through the weekend. By late Sunday into Sunday night the southerly flow will increase ahead of an approaching frontal boundary. This should lead to SCA conditions to develop out on the ocean Monday into Tuesday as seas approach 5 ft or thereabouts. There may be a period where seas become more marginal and may actually fall below SCA conditions. However, the south to southwesterly flow is expected to increase into the day on Tuesday. This will make small craft conditions more likely once again on the ocean, with marginal small craft conditions becoming more likely for the near shore waters towards Tuesday afternoon.

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