Area Forecast Discussion National Weather Service New York NY 437 PM EDT Tue Jul 14 2020

SYNOPSIS. A back door cold front will pass through the area tonight. High pressure then builds in for mid week. The next frontal system will affect the region late Thursday through Friday night. High pressure will build in for the upcoming weekend. Another frontal system may impact the region for the beginning of next week.

NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/. Lingering scattered showers and thunderstorms will primarily impact southeast CT through early this evening, but a few pop up showers will be possible elsewhere.

The upper low along the New England coast will work offshore tonight, while a back door cold front drops NE to SW across the area overnight. At the same time, an upper ridge over the Ohio Valley and Great Lakes builds east.

Skies will generally be mostly clear the first half of the night with some wraparound clouds dropping south across New England and into the area by daybreak.

Overnight lows will be nearly seasonable, in the 60s most places to around 70 across the NYC metro.

There is a moderate risk for the development of rip currents at the ocean beaches through this evening.

SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/. An upper ridge builds across the area during this time, while surface high pressure over the Canadian maritimes builds southward across the area.

Models continue to show low-level moisture gradually working in beneath the subsidence inversion around 85h on Wednesday and then lower level moisture at night with an E/SE flow. Thus, skies will likely vary with partly sunny skies tomorrow to possibly becoming mostly cloudy at night.

Highs on Wednesday will be in the upper 70s to lower 80s, with lows in the 60s. This is near or slightly below normal.

There is a moderate risk for the development of rip currents at the ocean beaches Wednesday.

LONG TERM /THURSDAY THROUGH TUESDAY/. A sub tropical ridge along the eastern seaboard will be moving into the western Atlantic during Thursday as a trough across central Canada moves slowly to the east. A weak shortwave will be moving into the region along with a developing warm front. There have been some timing differences in how quickly this wave will move into the region, and the trend has been to slow down the movement. While there may be minimal chances for precipitation into the far western zones Thursday afternoon, the better chances now are Thursday night into Friday. The wave weakens Friday night as a boundary sinks to the south of the area.

The sub tropical ridge becomes reestablished Saturday and Sunday, and extends into eastern Canada. With the strong ridge in place a weak shortwave moving through the flow Sunday will dampen, and remain mainly to the north, having little impact for the area. A deep return flow with the ridge in place will bring above normal temperatures for the upcoming weekend, along with increased humidity levels. Guidance temperatures and dew points are now a little higher than previous guidance, and heat indices Saturday through Monday will range in the mid to upper 90s. A frontal boundary moving into the region Monday and Tuesday may affect high temperatures for Monday. And any storms that develop may be more across the northern tier, along the northern periphery of the ridge. A weak trough remains into Tuesday along with a surface frontal boundary. And with energy moving through the flow chances of precipitation will remain Tuesday.

There is a moderate risk for the development of rip currents at the ocean beaches Thursday.

AVIATION /20Z TUESDAY THROUGH SUNDAY/. A backdoor cold front will cross the area overnight, followed by high pressure building in for Wednesday.

VFR through the TAF period. There is a chance of MVFR ceilings tonight, but think if these occur they are likely to be confined to far eastern terminals.

North to Northwest flow will turn more westerly right along the coast as seabreezes try to develop this afternoon. Winds then shift to the NE after the frontal passage with speeds less than 10 kt tonight. Winds shift around to the SE Wednesday afternoon.

OUTLOOK FOR 21Z WEDNESDAY THROUGH SUNDAY. Wednesday. MVFR cigs possible in the morning, otherwise VFR. Thursday. VFR. Thursday night-Friday night. Chance of SHRA/TSRA with MVFR or lower conditions. Saturday and Sunday. VFR.

MARINE. Finally, a period where seas have gone below 5 ft on the ocean after a prolonged SE swell. Tranquil conditions are forecast on the waters as high pressure builds in late tonight into Wednesday.

A frontal system impacts the waters Thursday night into Friday night with the chance of thunderstorms. High pressure returns Saturday and Sunday, and then another frontal system impacts the area Monday. Winds and seas are expected to remain below SCA levels across the forecast waters Thursday through the upcoming weekend. With a prolonged southwest flow, that strengthens Monday, gusts and seas on the ocean waters may reach small craft levels.

HYDROLOGY. No significant hydrologic impacts forecast during the period.

EQUIPMENT. NYC NOAA Weather Radio Station KWO35 (162.55 MHz) is undergoing its final stages of testing, and is operating at full power.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
