Area Forecast Discussion National Weather Service New York NY 640 AM EDT Wed Aug 5 2020

SYNOPSIS. A weak cold front will linger near the region through this evening. The front then shifts offshore tonight and then stalls on Thursday as high pressure builds across the northeast. Weak waves of low pressure will move along the stalled front through Saturday. High pressure should return on Sunday into early next week.

NEAR TERM /UNTIL 6 PM THIS EVENING/. Forecast on track this morning.

A dry and warm day is in store for today. A weak frontal boundary will remain near the region, but the atmosphere is dry and no precipitation is expected. Skies should be mostly sunny with highs in the middle and upper 80s. Dew points starting in the upper 60s and low 70s will mix out a bit with heating of the day and W/SW flow. Dew points will stay highest near the coast where the flow becomes more southerly in the afternoon with sea breezes.

Dangerous rip currents are likely at the ocean beaches through this evening.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM THURSDAY/. The weak front moves to the south and offshore tonight and will stall into Thursday as high pressure builds over the northeast. The region will be sandwiched between the Western Atlantic ridge and a relatively broad upper trough from the Great Lakes down into the Gulf States. Disturbances within SW flow aloft are progged to move within the southwest flow aloft into Thursday. Waves of low pressure are likely to develop along the stalled front. While middle and upper level moisture increase on Thursday, the low levels remain dry due to the proximity of the surface high. Have elected to keep the forecast dry during the daytime on Thursday. Highs will be a bit below seasonal averages, generally in the low 80s.

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

LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/. The stalled front will likely lift northward on Thursday night into Friday. This is due to the upper trough axis approaching the eastern seaboard. The models continue to differ on precipitation development across the region due to the proximity of the surface high. The bulk of the lift and precipitation may remain just offshore, closest to the frontal boundary and axis of deeper moisture. There has been a trend in the guidance for some of this moisture to push close to Long Island, so have bumped PoPs up a bit across the region. Have included mention of thunder, but instability is marginal. Any showers associated with the frontal wave should diminish Friday night with a return to dry conditions on Saturday as the upper trough axis shifts east, pushing the deeper moisture and front further offshore. Clouds and possible showers will hold high temperatures down in the low 80s.

Heights generally rise this weekend as broad ridging builds across the southern and central US. This signals the beginning of a warming trend with temperatures in the middle and upper 80s Sunday into Monday. Humidity levels will also increase as dew points rise into the upper 60s and possibly low 70s early next week.

There may be weak shortwaves along the periphery of the ridge early next week, which could provide the next chance for showers and thunderstorms.

AVIATION /12Z WEDNESDAY THROUGH SUNDAY/. A cold front lays across the area today, then drifts south of Long Island tonight.

VFR thru the TAF period. W to SSW winds today, becoming N tngt. Speeds generally blw 10 kt. Some variability in wind direction possible due to the proximity of the front and the light flow.

NY Metro Enhanced Aviation Weather Support .

Detailed information, including hourly TAF wind component fcsts, can be found at: http:/weather.gov/zny/n90

KJFK TAF Comments: No unscheduled amendments expected.

The afternoon KJFK haze potential forecast is GREEN, which implies slant range visibility P6SM outside of cloud.

KLGA TAF Comments: No unscheduled amendments expected.

The afternoon KLGA haze potential forecast is GREEN, which implies slant range visibility P6SM outside of cloud.

KEWR TAF Comments: No unscheduled amendments expected.

OUTLOOK FOR 12Z THURSDAY THROUGH SUNDAY. Thursday-Saturday. Mainly VFR, isolated-scattered showers and thunderstorms at times with locally MVFR conditions. Sunday. Mainly VFR.

MARINE. Waves will gradually subside on the ocean today. A SCA remains in effect due to these elevated seas. Elsewhere, winds and waves blw SCA lvls.

A broad area of high pressure will then build into the region thru the weekend. This will keep winds and seas blw SCA lvls thru the period on all the waters.

HYDROLOGY. No hydrologic impacts are expected into early next week.

EQUIPMENT. NYC NOAA Weather Radio Station KWO-35 (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.
