Area Forecast Discussion National Weather Service New York NY 746 AM EDT Thu Apr 18 2024

SYNOPSIS
A slow moving warm front approaches from the southwest and moves through the area today. High pressure briefly builds into the region tonight and Friday before a cold front passes through Friday night into Saturday morning. High pressure then follows from Saturday afternoon through early next week. A weak frontal system will impact the region mid week.

NEAR TERM /UNTIL 6 PM THIS EVENING/
Forecast is on track with only minor changes needed. Previous discussion follows.

Stacked low over south central Canada will move slowly ENE today, with high amplitude upper level ridging over the northeast slowly moving east. additionally, upper level ridging over the eastern Great Lakes region shifts eastward today. At the surface, a warm front continues its approach but looks to stall to the southwest. A weak area of low pressure forms along this boundary and treks southeast.

Chances for showers will continue today, but will slowly diminish over the area as high pressure from southeastern Canada noses into the Northeast. This, coupled with an incoming ridge aloft will bring in just enough subsidence to bring showers to an end over much of the forecast area by late this afternoon. Showers may transition to just some drizzle given the abundant low level moisture with the maritime high building in.

The high building in with the weak low to our south will mean a strengthening easterly flow today. It does not look to be overly windy, with sustained winds of 15 to 20 mph and gusts to 25 mph along coastal sections this morning. Winds start to decrease this afternoon as the high continues to nose into the region, with the weak low well out to sea by this point.

The easterly flow will also mean cooler than normal temperatures for Thursday, with highs only in the upper 40s to lower 50s.

SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY/
The high continues building into the region Thursday night into Friday morning as the ridge axis pushes east, so dry conditions expected through this time frame. The warm front gets suppressed to the south due to the building high, but at the same time, the cold front associated with the low in Canada advances east.
However, as the cold front pushes east the line of showers and thunderstorms associated with it over the central Great Lakes region weakens as it moves over the eastern Great Lakes. Further weakening is expected as it runs into the high over the Northeast, so just chance to slight chance for showers are expected as this line moves through Friday night and Saturday morning (lingering showers for eastern areas).

Temperatures recover somewhat on Friday, with highs in the 50s region-wide. Even warmer conditions expected for Saturday with a westerly flow and downsloping conditions expected after the passage of the cold front. Went a couple of degrees above guidance for highs, which are expected to be in the middle to upper 60s.

LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/
High pressure will continue to build into the region through the second half of the weekend and remain in control of the weather through Tuesday.

A 500mb trough then shifts through the Great Lakes on Tuesday with an associated weak surface low and cold front. Rain chances increase Tuesday night into Wednesday as this system moves across the region.
Drier weather returns for Thursday.

Temperatures will be just below normal on Sunday. Temperatures rebound a few degrees on Monday through Wednesday with temperatures at or just above normal. Temperatures fall back a degree or two below normal behind the cold front on Thursday. Temperatures each day will be in the upper 50s or 60s.

AVIATION /12Z THURSDAY THROUGH MONDAY/
A slow moving warm front approaches from the southwest and moves through the area today.

IFR at most terminals, with some pockets of LIFR possible this morning. Further east at KGON, conditions are MVFR. These conditions are expected for much of the day, with improvement to MVFR not expected until around 00z. After 00z, improvements can be expected, generally from east to west. Expected periods of light rain/drizzle through about 18-20z.

Amendments will be likely for changing flight categories today, especially later this afternoon as conditions are expected to change.

Wind direction will be E to ENE for much of the TAF period.
Wind speeds increase this morning to 10-15 kt with gusts mainly in the 20-25 kt range, especially east of NYC and along the coast. KTEB and KSWF expected to have lower winds near 10 kts or less without gusts during the TAF period. KEWR may see gusts more occasional than frequent.

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

Amendments likely for changing flight categories.
Wind gusts may be more occasional than frequent, especially at KEWR.

OUTLOOK FOR 12Z FRIDAY THROUGH MONDAY...

Fri: VFR early, then MVFR afternoon and at night with a chance of showers.

Sat: MVFR with showers ending in the early morning, becoming VFR. W-WNW wind gusts 15-20 kt.

Sun through Mon: VFR.

MARINE
Easterly winds will increase today with 25 to 30 kt gusts expected on all waters as high pressure builds in from the northeast.

Wind gusts diminish tonight as the high continues to build in over the area. Non ocean waters will likely drop below 25 kt early early tonight. The ocean waters will likely have SCA gusts hang on for the first few hours of Thursday night before they also come down below 25 kt.

Seas build to 4 to 7 ft on the ocean by this morning into the afternoon, diminishing thereafter. However, they remain above or right around 5 ft tonight into Friday. Have extended the SCA on the ocean waters through tonight, but may need to extend the SCA over the ocean into Friday with a persistent, though slowly weakening easterly flow. Waves finally drop below 5 ft on the ocean by Friday night.

High pressure will continue to build over the area waters for the second half of the weekend and into the first part of next week.
This should keep conditions at sub-advisory level through at least Tuesday night. Conditions may build back to SCA levels for Wednesday with the next low pressure and associated cold front to approach.

HYDROLOGY
No hydrologic impacts are expected through trough next Thursday.
