Area Forecast Discussion National Weather Service New York NY 610 AM EDT Sat Jun 22 2024

A stationary boundary over New England will remain north of the area through the weekend. A cold front approaches late in the day Sunday and moves through late Sunday night into Monday morning. High pressure builds in for Tuesday, and moves offshore Wednesday as a cold front approaches from the west. The cold front moves slowly across the region Wednesday night into Thursday morning.
High pressure will return for Thursday night into Friday.

Forecast is generally on track. Patchy fog has developed across portions of NE NJ, the Lower Hudson Valley, and southern CT.
Some of the fog is dense and a Special Weather Statement has been issued until 9 am for the patchy dense fog.

The heat and humidity continues to be the main weather story for this weekend as a frontal boundary remains north of the area and high pressure remains centered over the northwestern Atlantic.

Continued south to southwesterly flow over the area will continue the warm advection into the area. Temperatures will be similar to Friday, as 850 temperatures are also similar to Friday. Highs across much of NYC should reach the middle 90s, and upper 90s for northeast NJ. EWR may see 100 once again today. Elsewhere upper 80s to lower 90s are expected across the Lower Hudson Valley and inland southern CT, while coastal CT and Long Island see highs in the middle to upper 80s. Combined with dew points in the 70s today, and maximum heat index values will reach 95 to 104 for much of the area. The area in and around EWR may see 105 or just above for a maximum heat index, but think this will be more isolated than widespread for that part of NJ and opted not to upgrade Heat Advisories to Excessive Heat Warnings.

Another round of showers and thunderstorms are expected today as a surface trough develops across western portions of the Lower Hudson Valley and western New Jersey. CAMs are in pretty good agreement in location and timing for today, starting across the aforementioned areas late this morning and moving east through the day.
Additionally, showers and thunderstorms may develop along Long Island and CT sea breezes. Some of the storms today may become strong to severe as instability rises to above 1500 J/kg across the interior this afternoon and 0-6 km bulk shear over 40 kt in some spots. However, just as the more favorable shear moves into the region, instability will be on the decrease and mid level lapse rates do not seem too impressive. SPC has placed the northeast New Jersey, the Lower Hudson Valley and much of southern CT in a marginal risk for severe storms, with the primary threats being damaging winds and large hail, so an isolate severe storm or two is not out of the question.

Flash flooding is also a possibility with any storms with PWAT values 1.75" to close to 2".

Warm overnight lows expected tonight, with the possibility that some parts of the metro area may not dip below 80, but for the most part, looking at lows in the upper 70s here. Lower 70s are expected for much of the rest of the area. Any showers and thunderstorms will diminish around and just after sunset with the loss of the instability.

Slightly warmer temperatures are possible Sunday as models continue to show 850 temperature rise into the 20-21C range. This will translate to highs in the middle 90s for NYC, and upper 90s to possibly just over 100 for northeast NJ. Elsewhere upper 80s to lower 90s are expected. Given an increasing southerly flow, more in the way of mixing is expected, which will help to lower dew points during the afternoon, and despite the fact that temperatures will be slightly warmer than Saturday, we are still expecting maximum heat index values to range from 95-104 for the most part. Again, in and around EWR may see 105+, but it is expected to be isolated.
Therefore, Heat Advisories continue.

The cold front approaches on Sunday, but a prefrontal trough will move through before the front. This will allow another round of showers and thunderstorms to move through late Sunday morning and Sunday afternoon, followed by more rounds of showers and thunderstorms Sunday night with the cold front. Dynamics may be a bit stronger as compared for Saturday, but once again instability looks to decrease as the higher shear values move into the area.

Similar PWAT values continue the possibility of flash flooding as well.

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.

Key Points:

* Heat wave ends Monday with a cold frontal passage.

* A couple of hot days are expected Tuesday and Wednesday ahead of a cold front that moves through Wednesday night into Thursday.

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

No significant changes with this forecast update, with a slightly slower trend in the cold front Wednesday night into Thursday, allowing for another hot and humid day Wednesday.

The heat wave ends Monday with a cold frontal passage, and a chance of showers and thunderstorms continuing until Monday evening, as the front moves east of the region.

Temperatures rebound Tuesday as high pressure moves off the mid Atlantic coast and a return flow develops later in the day.
Inland temperatures may once again reach 90 degrees, with heat indices close to the air temperatures, as dew points will be in the upper 50s to lower 60s.

With the return flow continuing Wednesday, and a little slower timing with the approach of another cold front, temperatures will be several degrees higher than Tuesday, with inland highs in the lower to mid 90s. Heat indices inland will be in the mid 90s as dew points climb into the mid 60s.

A slow moving cold front will bring an end to this shorter spell of heat, with chances for thunderstorms from late day Wednesday into Thursday morning.

Dry weather returns Friday as another high builds into the region.

SCA issued for winds and seas on the ocean water Sunday as S-SW flow strengthens with the approach of the cold front helping to increase the pressure gradient with the high off shore.
Gusts up to 30 kt possible Sunday afternoon for the ocean, as well as the south shore bays and the eastern sound zone, where SCAs were also issued. All other near shore waters are expected to occasional gust to 25 kt at this time, but this may change with further model runs.

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, and the SCA on the ocean waters goes through Sunday night because of the elevated wave heights.

A strong SW flow in the morning will be slowly diminishing, and becoming westerly, as high pressure builds toward the waters. Small craft conditions, mainly seas, will be on-going on the ocean waters Monday morning, with seas falling below advisory levels Monday night as winds become northwest.

Winds and seas across all the waters remain below advisory levels Tuesday and Tuesday night. SCA conditions will once again become possible on the ocean waters Wednesday with the approach of another cold front, as southerly winds increase.

Low and localized flash flood threat on today 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.

There is a chance for locally heavy rain from late day Wednesday afternoon into Wednesday night with a front moving through the region.

A moderate rip current risk should continue at the ocean beaches on today 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 to 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 today.
