Area Forecast Discussion National Weather Service New York NY 143 PM EDT Thu Jul 2 2020

SYNOPSIS. A weakening upper level low along the New England coast this morning will gradually pull away from the area today. A back door cold front will then pass through on Friday, followed by weak high pressure for the weekend. A weak frontal system approaches early next week.

NEAR TERM /UNTIL 6 PM THIS EVENING/. The fcst remains on track. Expect a bit of a respite today from the convection associated with an upper low over New England the last couple of days. The latter of which will gradually pull away from the area today with some drier air and building heights. HiRes models still hinting at some widely scattered convection during the mid to late afternoon across the interior. Outside of a seabreeze and differential heating, there is not much of a trigger with high a LFC due to drier air in the low levels.

The bigger story will be a noticeably warmer day with less cloud cover as high temperatures get well into the 80s with a few lower 90s across the interior and possibly NYC. The immediate coast will be a bit cooler with an afternoon seabreeze kicking in. It will also be less humid with dew points possibly dropping into the 50s in some spots this afternoon (although forecast in the lower 60s).

There is a moderate risk of rip currents at the Atlantic Ocean beaches today due to a continued SE swell.

SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY/. Expect a manly clear, seasonable night tonight with lows generally in the 60s, with a few 50s possible in some of the normally colder locations.

A blocking pattern featuring a high amplitude ridge across the mid section of the country will allow for some amplification of an upper trough across eastern Canada. In turn, this will send a backdoor cold front and building high over the Canadian maritimes southeast into the area Friday into Saturday. The cold front will work from NE to SW late Friday morning into the early evening hours. Ahead of the front, scattered showers and thunderstorms are likely, which will work west in the afternoon. The axis of greatest instability looks to be across the interior, especially north and west of NYC, where temperatures will once again get into the upper 80s and possibly 90 on Friday. SPC has placed this area under a marginal risk for Friday with the main threat being damaging winds (5 percent). Shear is marginal, so any severe is likely to be of the pulse type.

The cold front works west of the area Friday night with widely scattered showers possible overnight into Saturday morning with some shortwave energy in the NW flow aloft. However, expect a mainly dry 4th of July with a considerably cooler airmass in place with an easterly flow due to high pressure along the New England coast. Highs Saturday will be in the upper 70s to lower 80s, which is a few degrees below normal.

There remains a moderate risk of rip currents at the Atlantic Ocean beaches on Friday due to a SE swell.

LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/. High temperatures Sunday will moderate slightly with a widely scattered convection possibly inland in the afternoon.

By early next week, a stronger shortwave moves through the Great Lakes by Tuesday. At the surface, a warm front pushes through the area Monday into Tuesday, which may just wash out. Temperatures are seasonable with a slight warm up expected by midweek.

AVIATION /18Z THURSDAY THROUGH TUESDAY/. An upper level low along the northeast coast will begin to weaken and drift east today. A cold front will pass through on Friday.

VFR through the TAF period. There is a slight chance for a developing afternoon shower or isolated thunderstorm mainly for KSWF.

NW winds under 10 kt. Afternoon sea breeze development is likely at coastal terminals after 18z. Winds turn west/northwest late tonight.

OUTLOOK FOR 18Z FRIDAY THROUGH TUESDAY. Fri. Mainly VFR. Aftn/eve shwrs and tstms possible. Sat. Mainly VFR. Sun-Mon. Mainly VFR. Aftn/eve shwrs and tstms possible, especially wrn areas. Tuesday. Mainly VFR.

MARINE. Conditions should remain below SCA levels across all waters through the weekend with a weak low pressure system drifting south and east of the waters and high pressure building in from the Canadian maritimes. Winds may gust up to 20kts for a short period Saturday afternoon across the ocean waters due to the gradient between the high and low.

HYDROLOGY. Locally heavy rain is possible in any thunderstorms that occur over the forecast period, but widespread hydrologic issues are not anticipated.

TIDES/COASTAL FLOODING. The combination of a SE swell and increasing astronomical tides will bring waters levels across western Long Island Sound and the south shore back bays of western Long Island close to minor coastal flood benchmarks during the evening high tide cycles through the upcoming weekend. Based on Steven's NYHOPS-E being overdone the last few high tide cycles and considering it's coarser SNAP-Ex being better, preference remains toward a blend with the lower ETSS and ESTOFS. This brings water levels close to minor coastal flood benchmarks along the south shore bays of Nassau county this evening. Thus, a statement has been issued to address this potential. That being said, guidance all indicates a gradual uptick through the weekend due to the approaching full moon. Thus, there is the potential for a statement and/or advisory level event Friday through Sunday. The south shore bays of western Nassau appear to be most susceptible.

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.
