Area Forecast Discussion National Weather Service New York NY 431 AM EDT Sat Aug 8 2020

SYNOPSIS. A nearly stationary front will remain south of the area today. High pressure will build in for Sunday and Monday, then move out into the western Atlantic late Monday and Tuesday as a cold front approaches. The front will slowly pass across through Thursday, then stall to the south on Friday.

NEAR TERM /UNTIL 6 PM THIS EVENING/. A nearly stationary front will slowly sink south today. Meanwhile, aloft, a shortwave will pass over the region today. Not much in the way of showers or thunderstorms are expected today, especially with the best forcing south of the area. However, still can not rule out some precipitation, so will continue to carry slight chance POPs. It will start off mostly cloudy or overcast with some gradual clearing expected towards mid to late afternoon.

Temperatures today will climb into the upper 70s and lower to middle 80s. This will be just a degree or two below our normal for this time of year.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SUNDAY/. Surface high pressure begins to build into the region tonight, with mainly dry conditions. While no precipitation is expected, low stratus/fog is expected to develop around midnight and continue through sunrise Sunday morning. Uncertain how dense and fog will be so will just call it patchy for now. Lows tonight will continue to be warm ranging from the middle 60s to lower 70s.

Ridging will continue to gradually build into the northeast on Sunday. A weak shortwave moves into the ridge during the afternoon, passing mainly to the north. There will be increasing CAPE and instability during the day and isolated convection will be possible along sea breeze boundaries with increased convergence. Some of the forecast models to indicate at least some light precipitation Sunday afternoon. Have continued to not included slight chance probabilities, however did increase POPs with sea breeze development.

LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/. The building ridge will usher in increasing heat and humidity into mid week. There is increasing consensus and confidence that portions of the region will reach mid 90s heat indices Monday through Wednesday and possibly into Thursday, as temperatures will range 5 to 10 degrees above normal. The ridge will keep another shortwave moving to the north Monday. The only real change in the long term forecast is the slower trend in the longwave closed low moving across southern Canada and into the northern tier of the plains and upper midwest into the midweek period. This will delay the approach of a weak cold front, with Tuesday remaining mostly dry. There may be a few afternoon thunderstorms along the periphery of the ridge, and have slight chances into the Lower Hudson Valley.

As the mid and upper flow becomes more parallel to the cold front, the front will slow its eastward progression, and convection will once again be mainly to the west and north Wednesday. The front is expected to move through Wednesday into Thursday and then stall south of the region Friday.

AVIATION /09Z SATURDAY THROUGH WEDNESDAY/. A stationary front will remain south of the area today before high pressure builds back into the region tonight.

MVFR to IFR ceilings across Long Island this morning from KJFK/KLGA east will linger through at least mid morning before conditions improve to VFR this afternoon. Elsewhere, conditions have largely improved to VFR, although would not be surprised to see MVFR conditions return at least briefly towards daybreak. An isolated afternoon shower or thunderstorm is possible for NYC/NJ and western terminals. MVFR or lower conditions are expected to return at most terminals overnight.

Light E-NE or light and variable winds will continue through the morning. By afternoon, SE flow develops with winds remaining less than 10 kt. Winds become light and variable at all terminals overnight tonight.

OUTLOOK FOR 06Z SUNDAY THROUGH TUESDAY. Saturday Night. MVFR or lower conditions likely in stratus/fog. Sunday. Becoming VFR. MVFR or lower conditions may return Sunday night, primarily at eastern terminals. Monday . VFR. Tuesday and Wednesday. Low prob of aft/eve rain showers and isolated thunderstorms.

MARINE. Winds and seas will remain below SCA criteria through Wednesday with a light pressure gradient over the area.

HYDROLOGY. No hydrologic impacts are expected through Wednesday.

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.
