Synopsis for the long island waters and new york harbor.. A weakening cold front moves through tonight. High pressure remains over the area Monday into midweek. Meanwhile, a nearly stationary frontal boundary south and east of the area will have waves of low pressure moving along the front. The boundary may move back towards the area at some point during the mid to late week period which would bring waves of low pressure closer to the area.

Area Forecast Discussion National Weather Service New York NY 1010 PM EDT Sun Aug 1 2021

SYNOPSIS. A weakening cold front moves through tonight. High remains over the area into midweek. Meanwhile, a nearly stationary frontal boundary south and east of the area will have waves of low pressure moving along the front. The boundary may move back towards the area at some point during the mid to late week period which would bring waves of low pressure closer to the area. Weak high pressure is expected to be in control Saturday and Sunday.

NEAR TERM /UNTIL 6 AM MONDAY MORNING/. Made some minor updates made to reflect current temperatures and observations. Showers will continue progressing west to east through the overnight, eventually coming to an end before sunrise.

Both instability and CAPE are low and will mention isolated thunderstorm. Will keep the isolated down to the coast at this time, however, with less instability and CAPE the possibilities are minimal.

A line of showers and thunderstorms associated with a weakening cold front, and a shortwave aloft will move through the forecast area tonight. The line is expected to weaken as it heads east overnight.

A northwest flow will develop overnight, allowing temperatures to remain a few degrees below normal for lows, which will range from the middle 50s across inland areas, to the middle 60s in the New York City metro area. Dew points will begin to fall as well tonight.

SHORT TERM /6 AM MONDAY MORNING THROUGH MONDAY NIGHT/. Dry conditions expected for Monday and Monday night as high pressure builds in from the west. Continued seasonably cool during this time frame as the northerly flow continues. Highs will be in the upper 70s and lower 80s and lows in the 50s and 60s.

LONG TERM /TUESDAY THROUGH SUNDAY/. Longwave trough remains across eastern Canada and the eastern states. The trough does become less amplified as additional weak shortwave energy rotates into the trough, and this energy become closed off and nearly cutoff from the northern stream. There will be little eastward progression of western Atlantic ridging and the trough. Meanwhile a surface boundary will remain nearly stationary offshore as wave of low pressure attempts to move northward. There is some uncertainty as to how close the boundary gets to the coast and where exactly the boundary will become nearly stationary. Therefore there remains a good degree of uncertainty for the middle and latter part of the week with regard to POPs and even sky cover. For now the best bet is to have higher chance POPs further east for a portion of this time frame, with lower POPs further north and west. Went a little more optimistic for the late week, but the uncertainty remains rather high. Thought it prudent to go more optimistic later Friday into Saturday as heights overall are expected to rise a bit. The question remains how fast and to what degree this will occur.

AVIATION /02Z MONDAY THROUGH FRIDAY/. A dissipating cold front passes through the area overnight into Monday morning. A weak trough may set up across the area Monday afternoon.

A mainly VFR forecast, but there could be a short period of MVFR conditions before the cold front comes through, especially outside of the NYC terminals. Showers will be scattered through the overnight.

Light S/SE winds may go light and variable for a time ahead of the cold front. NW winds following the cold frontal passage will ramp up to around 10 kt by daybreak. There could be a few gusts 15-18kt especially through early afternoon.

. NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty .

A brief period of MVFR conditions are possible in any showers tonight and possibly ahead of the cold front as winds go light and variable. Occasional NW gusts 15-18 kt in the morning into early afternoon.

OUTLOOK FOR 00Z TUESDAY THROUGH FRIDAY. Monday Night through Tuesday. VFR. Wednesday-Friday. Mainly VFR with a chance of showers, especially east of the NYC terminals.

MARINE. Winds and waves are expected to remain below SCA criteria over all waters with lack of a strong pressure gradient.

Conditions are expected to remain below small craft criteria for the nearshore and western ocean waters through the forecast period. Later Wednesday and Wednesday night the eastern ocean waters may experience marginal small craft seas, but otherwise conditions should remain below small craft even here throughout much, if not all of the forecast period. Overall the pressure gradient is expected to remain relatively light with weak high pressure just off to the west and a stalled or slow moving frontal boundary offshore. The frontal boundary may approach closer than expected for the mid to late week, but the exact positioning of this boundary remains rather low confidence. Therefore some adjustments to the winds and seas forecast are possible in the upcoming days.

HYDROLOGY. No hydrologic issues are anticipated through next week.

TIDES/COASTAL FLOODING. There is a moderate risk for the development of rip currents at the ocean beaches Monday and Tuesday.
