Area Forecast Discussion National Weather Service New York NY 144 AM EDT Sat Aug 8 2020

SYNOPSIS. A stationary front will remain south of the area through early Saturday. 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 AM THIS MORNING/. A stationary front will remain to the south, with a few very weak disturbances riding along the boundary. Aloft, a deamplifying trough will move through. Associated showers over NYC and western Long Island are dissipating, and only expect isolated activity overnight.

As far as temperatures, mostly cloudy skies and humid conditions will keep temperatures from dropping too much. Expect lows to range from the mid 60s to around 70.

SHORT TERM /6 AM THIS MORNING THROUGH 6 PM SUNDAY/. The stationary front will very slowly sink south through the period. With much of the forcing for any showers and thunderstorms to remain south of the area, not much in the way of showers and thunderstorms are expected. With slightly warmer conditions inland, instability will be higher, so slightly higher PoP (chance) is warranted across northeast New Jersey and the Lower Hudson Valley. Otherwise, just a slight chance is expected. Many of the mesoscale models support this thinking.

Temperatures will continue to run at or just below normal on Saturday with highs in the upper 70s to lower 80s thanks to continued light northeasterly flow. Lows at night will continue to be warm ranging from the middle 60s to lower 70s.

LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/. Upper ridging will be gradually building into the northeast Sunday as 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. The GFS and ECMWF do indicate some light precipitation Sunday afternoon. At this time have not included slight chance probabilities, however did increase POPs with sea breeze development.

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 /06Z SATURDAY THROUGH WEDNESDAY/. A stationary front will remain south of the area today before high pressure builds back into the region tonight.

MVFR ceilings will continue to develop through the overnight hours, with IFR conditions at Long Island terminals. Sub-VFR conditions will linger into mid-morning before conditions improve to VFR at all terminals by afternoon. An isolated afternoon shower or thunderstorm is possible for NYC/NJ and western terminals. MVFR or lower conditions may return 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 through Monday. Mainly VFR. Low prob of late night/early morning MVFR conds. Tuesday and Wednesday. Low prob of aft/eve rain showers and isolated thunderstorms.

MARINE. Winds and seas will remain below SCA levels through Wednesday as lack of any pressure gradient keeps winds on the light side.

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.
