Area Forecast Discussion National Weather Service New York NY 209 PM EDT Tue Aug 11 2020

SYNOPSIS. A broad area of high pressure will continue to drift east over the Atlantic today. A cold front will approach tonight before stalling over the region through the end of the week. High pressure builds in for the weekend.

NEAR TERM /UNTIL 6 PM THIS EVENING/. The forecast remains on track this morning with only minor updates to temperatures and dew points over the next few hours to better capture the latest trends. Stratus clouds are continuing to mix into a cumulus field which should remain through the day.

Heat and humidity will continue today as surface high pressure drifts east over the Atlantic. Much like yesterday, high temperatures will rise into the lower 90s for locations from New York City north and west, and into the mid to upper 80s across Long Island and coastal Connecticut. With dew points remaining around 70 through the day, this will again result in heat index values in the mid 90s across much of the area. The Heat Advisory remains in effect through Wednesday for all but Suffolk County in New York and southern Middlesex and New London counties in Connecticut.

Once again, can't completely rule out a few diurnally driven showers and thunderstorms this afternoon and evening, but forcing remains limited. The best chances for any precipitation today will be across the interior.

There is a moderate risk of rip currents at Atlantic Ocean beaches today.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM WEDNESDAY/. Any showers and thunderstorms that do develop will quickly diminish after sunset with the loss of daytime heating. Meanwhile, a cold front will begin to approach from the west overnight before stalling across the area during the day on Wednesday. While much of the region will remain dry through the overnight hours, showers and thunderstorms ahead of the front could work eastward into portions of the Lower Hudson Valley after midnight. The better precipitation chances come during the day on Wednesday as the front stalls across the area, with showers and thunderstorms possible across much of the area.

While increased cloud cover on Wednesday will likely help hold temperatures a few degrees lower than earlier in the week, dew points will rise as moisture begins to pool along the front, resulting in another day with heat index values in the mid 90s across much of the area.

LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/. With the cold front remaining stalled across the area, shower and thunderstorm chances will continue through the beginning of the long term period. Some h5 energy embedded in the weak flow is progged to pass along and north of the surface front Thu and Fri. This would bring chances for shwrs and tstms each day. The energy is likely remnant upstream convection however, so confidence in timing, placement, and coverage is very low and probabilities were capped at the chance level. With precipitable water values increasing to around 2 inches on Thursday and weak flow aloft, can't rule out the potential for minor flooding with any showers/storms. The NBM with local adjustments was used for temps.

High pres builds in from ern Canada over the weekend. The latest 12Z model data suggests the influence will be strong enough to keep the cwa dry all weekend. Would prefer to see some consistency before pulling all pops attm, but numbers were limited to 20 percent or less, which was blw the NBM. Temps again based on the NBM.

A warm front possible for Mon. Pops were limited to slight chance as this is too far out for any timing confidence.

AVIATION /18Z TUESDAY THROUGH SUNDAY/. High pressure remains over the Western Atlantic as a weak cold front slowly approaches through this evening. The cold front then moves through the region Wednesday.

Stratus remains along the south shore of Long Island and was slowly moving northward, with periods of IFR conditions at KJFK and KISP. Otherwise VFR conditions are expected at the terminals into early this evening. Scattered showers and thunderstorms are likely along the sea breeze boundary across southern Connecticut and into northeastern New Jersey with local MVFR.

This evening IFR stratus is likely to move inland and remain through tonight. The best chance of showers and possibly a thunderstorm will be at KSWF overnight as the cold front moves into the area. At the coastal terminals just mentioned VCSH as the showers will be weakening.

The IFR stratus dissipates Wednesday morning with VFR developing.

Winds will be southerly through this afternoon with sea breezes. As the sea breeze weakens this evening wind become SW around 5 kt, with outlying terminals becoming light and variable. Wednesday morning winds will be SW 5 to 10 kt, except at KSWF where winds will be northwest. Afternoon sea breezes are expected Wednesday.

OUTLOOK FOR 18Z WEDNESDAY THROUGH SUNDAY. Wednesday aftn-Thursday. Chance for showers and thunderstorms with MVFR or lower conditions. Coastal IFR conditions possible Wednesday night. Friday. Chance of showers and thunderstorms with MVFR conditions. Saturday through Sunday. MVFR with a slight chance of showers.

MARINE. Winds and seas will remain below SCA criteria through Friday night. Increased ely flow behind a cold front over the weekend could produce sca conditions, especially on the ocean.

HYDROLOGY. Precipitable water values will increase to around 2 inches Wednesday night into Thursday as a cold front stalls across the area. With weak flow aloft, minor flooding will be possible in any showers and thunderstorms, primarily in urban and other poor drainage areas.

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.
