Area Forecast Discussion National Weather Service New York NY 223 AM EDT Sat Jun 22 2024

A cold front to the north of the region, slowly retreats back north as a warm front this weekend. A cold front approaches late Sunday, moving across Sunday night into Monday, followed by high pressure on Tuesday. Another frontal system will approach on Wednesday and move slowly across from Wednesday afternoon into Thursday. High pressure will return for Thursday night into Friday.

Region remains on NE edge of southern ridging, with subtle convectively induced vorts moving through flow. A cold front over central New England sinks south towards the region this eve, likely stalling just north of the forecast area late in the day into night.

Much of the area is now dry, with a cluster of showers/weak thunderstorms moving into the Lower Hudson Valley. This activity is expected to continue to weaken as it moves eastward.
Otherwise, very warm and muggy conditions overnight, with lows in the lower to mid 70s.

Upper ridge continues to sink south through the weekend, with deep layer flow aloft backing from W to SW. At the surface, cold front retreats north tonight and remains fairly stationary across central and SE New England through the weekend.

Heat continues to build through the weekend, with 850mb temps rising into the upper teens on Sat and 20-21C on Sun. Gusty SW flow and deep mixing will have surface temps similarly increasing each day away from the coast. High in the mid to upper 90s likely for NE NJ, NW NYC, and surrounding portions of LoHuD, with widespread upper 80s to lower 90s for remainder of the area. A strengthening S/SW flow will limit south coastal LI and SE CT in the lower to mid 80s each day. High temperatures on Sunday could touch or break daily records across NYC/NJ metro.

850mb TDs climb slightly Sat into Sun as well, indicating a slight upward trends in surface Td's as well, but still likely some Td mixout in the afternoon during peak heating. This expands the threat for 95 to 100 heat index into northern New London/Middlesex and NW LI for the weekend, continuing from today. Isolated 105 HI possible for NE NJ and immediate surroundings Sat and Sun, but too low coverage/confidence for upgrade to excessive heat at this time. T/Td trends will be monitored thru the weekend for possible upgrade. Blend of deterministic NBM and HRRR for T and Td seems to be verifying well.

Focus for tstms Sat aft/eve looks less clear than today as warm front pushes farther north into northern New England. Isolated convective initiation possible along sea- breeze and off higher terrain to the NW (drifting east) in moderate to strong instability but still weak shear/mid level lapse rate environment. More widespread convective development possible along backdoor cold front moving westward across SE New England, but this appears to stall east of the area, but could clip far SE CT. For now, have capped pops at high chance for interior, to slight/low chance for the coast, based on the above. Isolated wet microburst potential with any convective development along and north of these boundaries in moderate to strong instability and weak shear/mid-level lapse rate environment.

A seemingly better chance for organized convection late Sun into Sun Eve with lead shortwave ahead of digging Great Lakes shortwave and pre-frontal trough approaching from the west. This approaching system will strengthen wind fields and deep layer shear over the region, likely promoting better organizing of upstream convection and longer lived updrafts. Question is timing of this convection into our area. Moderate to strong instability is likely once again across NYC and pts N&W Sun afternoon, but late day/evening timing of convection would not maximize potential. Marginal severe threat from SPC looks reasonable based on mismatch btwn shear/and peak instability timing, and strong synoptic S/SW flow disrupting any clear focus outside of elevation.

Low and localized flash flood threat both days with isolate to scattered convective coverage on Sat, and likely better forward progression of convection on Sunday.

Key Points:

* Heat wave comes to an end Sunday night-Monday with a cold frontal passage.

* One more hot day expected ahead of another frontal system on Wednesday.

* A slow moving frontal system could bring locally heavy rainfall from late Wednesday into Thursday.

NBM was generally followed, with some adjustments mainly to to temperatures and dewpoints per 12Z GFS and 00Z ECMWF guidance.

The heat wave should come to an end as an upper trough/closed low and associated cold front approach the area Sunday night into Monday. A few tstms with gusty winds possible Sunday evening via pre- frontal deep layer unidirectional shear (mid layer SW-W flow 35-50 kt) and leftover steep lapse rates from daytime heat. Brief heavy rain could also be possible with any storms.

Front clears the area daytime Mon, with any 90-plus temps shunted just south into central NJ, and heat index values close to actual temps.

Tue should be a bit warmer with high pressure and downslope W-NW flow in control. High temps will range from 85-90 in most places, with similar heat index values as afternoon dewpoints should be no higher than the upper 50s/lower 60s. Wed will be a little warmer and more humid still, with high temps 90-95 from NYC north/west and the heat index approaching or just surpassing 95 for one day as afternoon dewpoints increase to the lower/mid 60s.

A slow moving frontal system should bring an end to this shorter spell of heat, with chances for tstms from late day Wed into Thu.
More on this in the Hydrology section.

Locally heavy rainfall possible with PW approaching 2 inches and some potential for training cells along the slow moving frontal boundary. Attm Fri looks dry with temps near or just above the seasonal avg.

High pressure remains across the Western Atlantic as a front lingers north of the region.

Mainly VFR. A few weak showers were moving across Long Island and in the vicinity of the NYC metro terminals at 06Z. Low confidence in and patchy fog/stratus developing toward morning for the eastern terminals, and not included in the TAF at this time.

Winds will be light S/SW to light and variable overnight, and become S by late Saturday morning, generally under 10kt. Any gusts will be late in the afternoon, and may be more occasional.

Showers and thunderstorms are possible again this afternoon/evening. Thunders will likely be isolated and confidence remains too low to include in the TAF anywhere except KSWF. PROB30 for SHRA was included elsewhere.

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

Low to moderate confidence in the timing of showers and thunderstorms this afternoon, and may be later than current forecast.


Late Saturday Night: Mainly VFR. MVFR to IFR possible east of the New York City metro terminals.

Sunday: Mainly VFR. Showers and thunderstorms becoming likely late day into the night. S-SW wind gusts 15-20 kt.

Monday: Mainly VFR. Chance of showers and thunderstorms, mainly in the morning.

Tuesday: VFR.

Wednesday: MVFR or lower at times with showers and thunderstorms possible.

Conditions will remain below SCA levels through at least Saturday.
Marginal SCA conditions possible for ocean waters leading to NY Harbor and surrounding near-shore waters with afternoon coastal jet development and seas of 3 to 5ft.

Higher confidence in SCA for winds and seas on the ocean water Saturday Night into Sunday as S-SW flow strengthens. Gusts up to 30kt possible Sunday aft. Nearshore non- ocean waters may see advisory gusts conditions as well Sunday aft.

SW flow 20-25 kt on the ocean with a few higher gusts to 30 kt Sunday night will maintain significant wave heights of 6-8 ft during that time frame, lowering only to 5-7 ft daytime Mon as SW flow 15 kt continues. These seas should then gradually diminish below 5 ft Mon night as a cold front passes and winds shift offshore.

Conditions fall below small craft late Monday night into Tuesday morning.

Isolated thunderstorms may produce brief heavy downpours that could lead to brief nuisance flooding, but the threat for more significant flooding this evening has ended.

Low and localized flash flood threat on Saturday with any slow moving isolated to scattered tstm activity across interior.

Low flash flood threat late Sunday into Sunday Night with possible scattered convection development along/ahead of pre- frontal trough/cold frontal passage.

Another chance for locally heavy rain may come from late Wed into Thu with another frontal system. PW again increases close to 2 inches and deep layer SW flow could favor training of cells, but this remains inherently uncertain 5-6 days out.

A moderate rip current risk should continue at the ocean beaches on Saturday via combo of 3-ft SW wind waves and 2-ft long period SE swell. A high risk is likely for Sunday as S-SW flow increases to 20- 25 kt and 5-ft S wind waves increase to 6-8 ft in the afternoon.

Will only mention the high risk in the SRF and HWO and hold off on rip current statement issuance, to avoid any confusion with the moderate risk for Saturday.
