Area Forecast Discussion National Weather Service New York NY 751 PM EDT Sat Jul 4 2020

SYNOPSIS. Weak high pressure remains over the region through Monday with a series of surface troughs developing over or shifting through the area Sunday and Monday. A warm front approaches late Tuesday into Tuesday Night, moving north through the region Wednesday morning. Weak high pressure builds into the region through the end of the week. A cold front and southern low pressure system will approach the area on Saturday, and then move east of the region Saturday Night into Sunday. Canadian high pressure builds in for the start of the workweek.

NEAR TERM /UNTIL 6 AM SUNDAY MORNING/. One shortwave slides east this evening, while the next shortwave approaches overnight. With weak instability and weak trough in the area, an isolates shower is possible overnight.

Outside of valley fog across the Interior, potential for stratus/fog across coastal SE CT and E LI.

Temps near seasonable, mainly in the 60s, except around 70 for NYC/NJ metro.

SHORT TERM /6 AM SUNDAY MORNING THROUGH MONDAY/. Weak high pressure remains over the region Sunday and Monday. For Sunday, shortwave shifts through during the morning to midday hours. Probably not enough moisture and instability for a mention of showers during this period. Additional shortwave lift could come into play late in the day to early evening for the NE portion of the forecast area. Mid level lapse rates will be probably be highest here, however lower levels will be more stable within the sea breeze influence. Will maintain a slight chance of a shower/TSTM for the inland NE CT zones. Elsewhere, mid level dry air and/or capping will probably overcome any lift and keep things dry.

It'll be warmer on Sunday versus today, with 850mb temps at around 17C. Highs in the mid 80s to lower 90s with the highest readings in NE NJ. Relatively dry air from aloft will mix down to the surface with daytime heating to offset some of moisture from a southerly surface flow, so heat indices are expected to remain below 95.

Weak low pressure shifts SE through New England Sunday night, moving offshore late at night. This will bring a surface trough through forecast area. Can't completely rule out a shower over parts of SE CT, otherwise dry with the passage of the trough.

Monday looks similar to Sunday with a thermal trough setting up over the region during the afternoon. What's different is that models imply that the surface trough that moves offshore late Sunday night drifts back north towards us with moisture convergence along it. Mechanical lift aloft appears to be lacking with with primarily NVA, so lift will probably need to come from sea breezes or higher SBCAPE to produce showers and thunderstorms. Will go with slight chance to chance PoPs in the afternoon. There could be more clouds to offset higher 850mb temps on Monday, so high temps again in the mid 80s to lower 90s with heat indices below 95.

There is a moderate rip current risk for the Atlantic Ocean facing beaches on Sunday and Monday, due to combination of long period SE swell, a small S wind wave, onshore flow of 10 to 15 kt, and large tidal range.

LONG TERM /MONDAY NIGHT THROUGH SATURDAY/. Models in good agreement with weekend shortwave troughing moving east on Monday, and the region lying on the northern edge of broad CONUS ridging through the week. This will be a dirty ridge though, with a weak closed low over the Mississippi River Valley early in the week slowly shearing/lifting towards the east coast through the week, before interacting and amplifying a bit with a northern stream shortwave and slowly sliding through the area this weekend. Before then, a midweek northern stream shortwave moving through S Canada may buckle the ridge enough to provide a trigger for afternoon diurnal convection, particularly Wed.

At the surface, the area will initially be under the influence of a moderating Canadian maritime airmass Monday and Tuesday with surface high pressure slowly sliding east through the Canadian maritimes in wake of departing shortwave energy. This should keep the area fairly quiet to start the week, with onshore flow and any focus for convection staying to the W and SW of the region.

A warm front approaches late Tuesday into Tuesday Night and likely lifts through the area Wednesday morning, with some indication of an earlier mentioned very weak shortwave/buckling of trough moving through aloft. This will present a trigger for convection Wed, particularly in the aft/eve, although the focus is a bit more vague at this point. This warm frontal passage and SW flow will begin a stretch of very warm and humid weather into at least Friday, and possibly Saturday. Heat indices of around 95 degrees possible for NE NJ, NYC metro and Lower Hud, with widespread highs in the mid to upper 80s, to around 90 NYC metro and NE NJ and Interior valleys.

Indication of building heights on Thursday and Friday, with region warm sectored. Progress of the earlier mentioned shearing southern closed low will determine if there is a trigger for afternoon convection both days, but at this point doesn't looks so. Looks like this feature still may be well SW/S of the region. So only a conditional potential for some isolated convection off terrain and seabreeze boundaries in a moderate to highly unstable airmass, but likely weakly capped and weak shear. Widespread temps in the upper 80s to lower 90s likely for Thursday with heat indices of 95-100 likely. Temps and heat indices on Friday become a bit more uncertain, predicated on evolution of southern low, and timing and track up the coast. Potential for temps and heat indices to rise to similar levels as Thursday, but potential onshore flow and increased cloud cover ahead of the southern low may limit potential heating.

Then, as mentioned the interaction of the next northern stream shortwave and the southern low, will likely result in amplification of troughing down the East Coast. Indication of the southern low tracking up the coast on Saturday, as a cold front approaches the region. Quite a bit of spread in the evolution of this low and interaction with the frontal boundary, but potential exists for more widespread shra/tsra activity in very moist (PWATS of 2-2 1/2") and unstable environment. If the southern low interacts with the front as it moves through the area, an excessive rainfall threat would exist. Will of course have to monitor NHC forecast for any tropical/sub tropical characteristics to this low as well. Otherwise, very warm and very humid conditions likely for Saturday, but high temperatures and heat indices will depend on evolution of upper low.

Fairly good agreement on mean troughing lingering Sunday into Monday, with cold front coming through the area Saturday Night. A very warm but drier airmass likely as Canadian high pressure sliding across Northern New England.

AVIATION /00Z SUNDAY THROUGH THURSDAY/. Weak high pressure will remain over the area.

Mainly VFR through the TAF period. Will have to keep an eye on some terminals for low ceilings overnight into early Sunday morning. Most likely this will occur at KGON, and possibly KISP. Elsewhere cannot totally rule out brief MVFR cigs right around or just after daybreak.

Light winds tonight will become more westerly, then northwesterly towards daybreak. Coastal sea breezes are expected once again Sunday afternoon.

OUTLOOK FOR 00Z MONDAY THROUGH THURSDAY. Sunday night. Mainly VFR. Monday through Thursday. Afternoon/evening showers and thunderstorms possible, mainly from the NYC metros north/west.

MARINE. Sub SCA conditions are expected across all waters through next week due to a weak flow. Seas of 2 to 3 ft to start the week, with a persistent S/SW flow will have wind waves building to 3 to 4 ft for mid to late week, with a background E/SE swell.

HYDROLOGY. Widespread hydrologic issues are not anticipated at this time.

TIDES/COASTAL FLOODING. A Coastal Flood Advisory is in effect for southern Nassau County tonight.

A light SE flow, and weak SE swell, in conjunction with high astronomical tides and background anomaly will have water levels a few tenths above minor flood thresholds for the the south shore bays of Nassau county, while vulnerable locales along Jamaica bay, lower NY/NJ harbor, and the shoreline of southern Fairfield and southern Westchester will likely touch or slightly exceed minor flood thresholds.

The threat for localized minor coastal flooding should lessen on Sunday as tide levels slowly fall.

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