Area Forecast Discussion National Weather Service New York NY 1058 AM EDT Thu Apr 18 2024

SYNOPSIS
A weak wave of low pressure off the Mid Atlantic coast will keep a frontal boundary well to the south today. High pressure will briefly build in tonight into Friday before a cold front passes through Friday night into Saturday morning. High pressure will then follow from Saturday afternoon into early next week. A weak frontal system will impact the region mid week.

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

Stacked low pressure over south central Canada will move slowly ENE today, with high amplitude upper level ridging over the Northeast and eastern Great Lakes region shifting eastward. At the surface, a weak wave of low pressure off the Mid Atlantic coast will keep a frontal boundary well to the south.

Chances for showers will continue today, but will slowly diminish as high pressure noses in from SE Canada. This, coupled with the incoming ridge aloft, will bring in just enough subsidence to bring showers to an end over much of the area by late afternoon. Showers may transition to just some drizzle given 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 diminish this afternoon as the high continues to nose into the region, with the weak low well out to sea by this point.

The E flow will also mean cooler than normal temperatures, with highs only in the upper 40s/lower 50s.

SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY/
The sfc high will continue building in through Friday morning as the upper ridge axis moves east, so dry conditions expected through this time frame. A cold front associated with the low in Canada will advance east, with an associated line of showers and thunderstorms over the central Great Lakes region weakening as it heads toward the eastern Great Lakes and then runs into the high over the Northeast. So just chance to slight chance for showers 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.
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 mid/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 just below normal on Sunday should rebound a few degrees from Monday through Wednesday, to near 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 /15Z THURSDAY THROUGH MONDAY/
Weak low pressure slowly moves southeast of the terminals through this evening. High pressure builds in from Maine through Friday morning.

Mainly IFR conditions into this afternoon with some improvement to MVFR likely for CT terminals. Light rain and drizzle will continue into the afternoon. Improving conditions should gradually make their way southwest into this evening with MVFR becoming likely at Long Island terminals after 19-20z and then elsewhere 22-00z. Improvement to VFR is then likely overnight.

Amendments will be likely for changing flight categories into the evening.

ENE-NE winds 10-15 kt with gusts 20-25 kt, especially NYC on east. Gusts end this evening with NE winds under 10 kt overnight.

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

Gusts may be occasional into the afternoon.

Amendments for changing flight categories likely into the evening.

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 except NY Harbor as high pressure builds from the northeast.

Gusts diminish tonight as the high continues to build in. The non ocean waters will likely drop below 25 kt early this evening if not sooner. The ocean waters will likely have gusts over 25 kt hanging on into this evening.

Ocean seas build to 6 to 9 ft today and up to 5 ft on the far ern Sound zone (western Block Island Sound), diminishing thereafter but remaining above 5 ft on the ocean into daytime Friday. Have extended SCA for the ocean into daytime Fri.

High pressure will continue to build early next week.
This should keep conditions at sub-advisory levels through at least Tue night. Conditions may build back to SCA levels on Wed with the next low pressure and associated cold front to approach.
