Area Forecast Discussion National Weather Service New York NY 1115 PM EDT Fri Jul 3 2020

SYNOPSIS. A backdoor cold front will push across the area tonight. High pressure will build in for the weekend. A weak frontal system approaches early next week and remains in the vicinity through the middle of the week. Another low system approaches from the southwest by week's end.

NEAR TERM /UNTIL 6 AM SATURDAY MORNING/. Latest surface analysis depicts the cold front south of Long Island, with drier air advecting in under light northeast flow, especially across southeast CT. Shower and thunderstorm activity has pushed offshore at this hour, with only a few remaining light showers over the lower Hudson Valley. The potential exists for some patchy fog across the interior overnight. Saturated ground from this evening's rainfall combined with light winds toward daybreak increase the possibility, but confidence is low given the drier airmass moving south, so for now have left it out of the forecast given the very patchy nature.

Temperatures will be in the mid 60s to around 70 tonight under a clearing sky.

SHORT TERM /6 AM SATURDAY MORNING THROUGH SUNDAY/. The cold front will sink further to the south on Saturday allowing a more seasonable airmass to settle into the region. Temperatures on Saturday will be in the 80s, with the immediate coast seeing temperatures in the upper 70s. A passing shortwave may spark off a few showers late in the afternoon across the northwest interior, but generally Saturday should be mainly dry.

A partly cloudy night expected with the weak wave passing overhead, with lows in the 60s across the region.

LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/. A back door cold front approaches from the north Sunday night as an upper trough located over New England heads east. As ridging builds in from the west by Monday, the front stalls to the south by Tuesday, resulting in chances for showers and thunderstorms starting Monday and continuing through next Thursday. This period will be characterized by typical summertime diurnal showers and thunderstorms as the frontal boundary appears to be weak with very Little forcing.

There is a moderate rip current risk for the Atlantic ocean facing beaches for Sunday.

By Tuesday, upper ridging moves overhead and surface winds shift to the south bringing in a warmer and more humid airmass for much of the week. Temperatures and dewpoints will increase each day starting on Tuesday. Highs will be in the upper 80s to lower 90s during this time frame, with the warmest readings expected across the New York City metro area and northeast New Jersey. The combination of heat and humidity results in heat index values in the middle to upper 90s range, leading to possible Heat Advisories being issued. Wednesday through Friday seems like the more likely days, with heat index values of 95 to 99.

A shortwave trough approaches from the southwest by Friday bringing a weak surface low toward the area, enough to warrant increased shower chances on Friday.

AVIATION /03Z SATURDAY THROUGH WEDNESDAY/. A back door cold front now just about through our local area.

Showers/tstms have come to an end, but ceilings have fallen to MVFR and IFR in most spots. These cigs are expected to remain down most of the night. Skies will start to scatter out mainly during the mid to late morning hours on Saturday with daytime heating. VFR conditions are expected for Saturday afternoon.

Winds will become E-NE with passage of the back door front. Winds are expected to southeast late Saturday afternoon.

OUTLOOK FOR 00Z SUNDAY THROUGH WEDNESDAY. Saturday night and Sunday. Mainly VFR. Monday through Wednesday. Afternoon/evening showers and thunderstorms possible, mainly across the Lower Hudson Valley and NJ terminals.

MARINE. Sub SCA conditions are expected across all waters through the weekend as weak high pressure builds in. Northeasterly winds behind a cold front on Saturday afternoon may briefly gust 15-20 kt. Waves 3 to 4 feet over the ocean Saturday relax to 3 feet Sunday as winds become more southerly during the day.

HYDROLOGY. Localized flash flooding is possible into early this evening. Rainfall amounts will generally be an inch or less, with localized amounts exceeding 2 inches.

TIDES/COASTAL FLOODING. A coastal flood statement has been issued for Lower New York Harbor and the south shore back bays of Queens and Nassau Counties for this evening's high tide cycle.

A SE swell over the last several days in conjunction with increasing astronomical high tides has gradually raised water levels. Recent guidance, in particular, Steven's NYHOPS-E has been several tenths too high the last several high tide cycles. While there is good agreement that the south shore back bays will get into minor tonight, with a diminishing swell and only slightly higher astronomical high tides this evening compared to last, confidence is not sufficient at this time to issue a coastal flood advisory for widespread minor. Thus, the reason for only a statement. This will be further evaluated later today to assess recent performance with the high tide cycle this morning.

The threat for minor coastal flooding will continue through the weekend during the evening high tide cycles.

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

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
