Area Forecast Discussion National Weather Service New York NY 109 PM EDT Sun Aug 9 2020

SYNOPSIS. Weak high pressure will remain over the area today, then merge with high pressure over the western Atlantic, which will then dominate through mid week. A slow moving cold front will begin to approach on Wednesday, move into the area Wednesday night into Thursday, then stall to the south on Friday. The front may sink farther south on Saturday as stronger high pressure starts to build out of eastern Canada.

NEAR TERM /UNTIL 6 PM THIS EVENING/. The forecast remains on track. Weak high pressure will remain over the region today. Forecast models are indicating a shortwave moving across New England this afternoon. This shortwave along with sea breeze convergence may spark a few isolated showers or thunderstorms during the afternoon. Will continue to carry some slight chance PoPs across southern Connecticut, along with eastern Westchester and eastern Putnam as well as northern half of Long Island.

Temperatures today are expected to climb into the middle and upper 80s for most of the CWA, with lower 80s closer to the coast. This will be the first day of a warming trend across the region as the air mass moderates and warm air advects into the region from the west.

There is moderate risk of rip current at the ocean beaches today due to a long period 2-3ft swells.

SHORT TERM /6 PM THIS EVENING THROUGH MONDAY NIGHT/. As the shortwave moves east of the area tonight, upper ridging will builds further into the area into Monday. The weak surface high will merge with a larger Western Atlantic high pressure, with heat and humidity expected to return for the first half of the new work week. High temperatures will reach the upper 80s to low 90s across the NYC metro and interior, with middle and upper 80s elsewhere. Heat index values will come close to 95 across NE NJ, staying just below in the NYC metro, with heat indices near 90 elsewhere.

Forecast guidance is indicating there may be a few showers or thunderstorms mainly north of NYC Monday afternoon. Will introduce some slight chance POPs across the Lower Hudson Valley and southern CT.

Warm and humid conditions continue Monday night with the ridge over the region.

There is moderate risk of rip current at the ocean beaches on Monday due to a long period 2-3ft swells.

LONG TERM /TUESDAY THROUGH SATURDAY/. Weather features across the Northeast will be slow moving during much of this time frame, with the area sandwiched between a slow moving closed low moving from Ontario into Quebec, and an upper ridge over the western Atlantic. A developing omega block over Canada will further slow progression going into late this week.

Before a slow moving cold front begins to approach on Wed, we will have to contend with heat relates issues Tue into Wed, with widespread lower/mid 90s for highs on Tue, which along with dewpoints in the upper 60s/lower 70s should yield heat index values 95-100 away from south facing shores. High temps and fcst heat index values are more marginal on Wed despite higher dewpoints with the approach of the front, but could be underdone if there is more sunshine and/or positive low level theta-e advection ahead of the front. Shower/tstm chances will be confined mostly to the interior well NW of NYC.

The front will be slow to move through Thu into Fri, with less in the way of heat issues (mid 90s heat index values only in urban NE NJ) and more in the way of convection, with some potential for flooding, See Hydrology section for details.

The front will take some time to clear the area. Because of this it remain uncertain whether Sat will be dry despite high pressure starting to build out of eastern Canada, so maintained chance PoP for most of the area.

AVIATION /18Z SUNDAY THROUGH FRIDAY/. High pressure over the terminals today shifts to the Western Atlantic tonight into Monday.

Mainly VFR through the forecast period. However, there is a chance for IFR or MVFR near the coast. The highest chance for seeing low conditions is at GON. Have left out of the TAF at ISP, JFK, and BDR for now as the stratus will likely stay to the east of these terminals.

S-SW flow this afternoon around 10 kt, slightly higher at JFK. A SE sea breeze is still possible at KEWR after 19z. Winds diminish tonight before becoming W-SW Monday morning under 10 kt. Sea breezes are likely late morning into the afternoon.

OUTLOOK FOR 18Z MONDAY THROUGH FRIDAY. Mon Afternoon-Tue. VFR. MVFR or lower stratus/fog possible for eastern terminals at night. Isolate shower or storm NW of NYC possible in afternoon. Wed-Fri. Increasing chance for afternoon/evening showers and thunderstorms with MVFR or lower possible.

MARINE. A weak pressure gradient in place through early next week will lead to winds and seas below SCA criteria.

HYDROLOGY. There appears to be some potential for flooding Thu into Fri, with a slow moving cold front Thu into Fri. PW increasing to over 2 inches and flow aloft aligning more with the approaching front could lead to tstms capable of producing heavy rain, as well as training cells especially Thu afternoon/evening. Still lots of uncertainty here as frontal timing would have have to coincide with peak daytime heating/instability to realize this potential.

OKX WATCHES/WARNINGS/ADVISORIES. CT . None. NY . None. NJ . None. MARINE . None.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
