Synopsis for the long island waters and new york harbor.. A weak surface low pressure trough will persist nearby into Monday, before a backdoor cold front passes through Monday afternoon into night. This front will lift toward the area on Tuesday afternoon, and lift north by Wednesday morning. Weak high pressure will then briefly build in through Thursday. A southern low will approach and track near the area from the south Friday into Saturday, with a series of weak fronts moving through the area this weekend into early next week.

Area Forecast Discussion National Weather Service New York NY 745 PM EDT Sun Jul 5 2020

SYNOPSIS. A weak surface low pressure trough and frontal boundary will persist nearby into Monday night, while weak upper level disturbances pass across. A warm front will lift toward the area on Tuesday, and lift north by Wednesday morning. Weak high pressure will then briefly build in through Thursday. A southern low will approach and track near the area from the south Friday into Saturday, with a series of weak fronts moving through the area this weekend into early next week.

NEAR TERM /UNTIL 6 AM MONDAY MORNING/. Potential for an isolated shower or thunderstorm this evening over interior SW CT this evening across interior CT in response to shortwave energy moving through Central/SE New England.

Otherwise dry tonight with lows from 70-75 in and just outside NYC, to the lower 60s in the interior valleys well inland.

SHORT TERM /6 AM MONDAY MORNING THROUGH MONDAY NIGHT/. A sfc frontal boundary and thermal trough should be in the vicinity on Monday. Another very warm day expected, with highs 90-95 across much of the interior and along the north shore of Long Island, with mid/upper 80s in the higher elevations and along south facing coastlines. Another mid level shortwave trough dropping down from the NW should trigger sct to numerous showers/tstms late Mon afternoon into Mon night, with the best chances across the NYC metro area into northern NJ. Combo of MLCAPE as high as 1500 J/kg and undirectional 0-6 km NW shear of about 35 kt suggest multicell organization possible, and steep low level lapse rates/relatively dry mid levels could lead to damaging wind gusts with the strongest cells.

Chances for showers/tstms could continue overnight Mon night with the sfc boundary remaining nearby and additional mid level shortwave energy sliding across, but not expecting this to be problematic attm. Low temps Mon night should be in the lower 70s across the NYC metro area, with 60s farther north and east.

LONG TERM /TUESDAY THROUGH SUNDAY/. The region will lay 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 area to end the week. Thereafter, models with better agreement of amplifying northern stream troughing approaching/entering the area this weekend, and likely remaining over the area through at least early next week. 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 maritime airmass Tuesday with surface high pressure slowly sliding east of the Canadian maritimes in wake of departing shortwave energy. Models have trended with a warm front closer to the area on Tuesday, and perhaps impinging on far SW parts of the region. This warm front will be the leading edge of a hot and humid and unstable airmass. Forcing for convection is not distinct at this time, with main trigger being vort energy riding along the periphery of the ridge. If the warm front can work into or close to portions of the region, with sufficient trigger, there is a conditional threat of isolated strong to severe storms across far SW portions of the region (NYC/NE NJ). Further N and E, perhaps W LI and Lower Hud Valley and instability should be more elevated with low-level onshore flow, but with weak steering flow, and PWAT increasing to 2+", this presents potential for heavy downpours and a localized flash flood threat. Working farther NE towards SE CT, conditions will likely be more stable. Something to monitor, as a warm front farther to the SW will limit the severe and flash flood threat over area, while farther NE over the area would increase the threat.

A warm front is expected to lift through the area early Wednesday morning, with some indication of an earlier mentioned very weak shortwave/buckling of trough moving through aloft. This may present a trigger for late afternoon/early eve isolated to scattered convection Wed, although the focus is a bit more vague at this point and (higher terrain, perhaps sea breeze boundary). This warm frontal passage and SW flow will have widespread high temps climbing into the upper 80s to lower 90s, with widespread heat indices in mid to upper 90s degrees as dewpoints climb into the lower 70s.

Heights continue to build on Thursday, but progress of the earlier mentioned shearing southern closed low will have to be monitored as it potentially starts lifting towards the Mid-Atlantic. Quite a bit of model spread on the evolution of this feature and its associated surface wave/low. At this time this feature appears to be far enough SW/S of the region on Thursday, for another hot and humid day. Although a backing wind flow may keep coastal areas a bit cooler than Wed. Only a conditional potential for some isolated convection off terrain and seabreeze boundaries in a likely unstable, but capped and weakly shear environment. If flow remains from the S/SW widespread temps in the upper 80s to lower 90s likely for Thursday with heat indices of 95-100 possible.

Forecast details become less certain Friday into the weekend, dependent on the evolution of the southern low as it lifts/shears up the coast, but confidence is increasing in a northern stream trough amplifying down through the Great Lakes/Ohio Valley and then to the East Coast during this time.

Considerable model spread exists on the southern low tracking up the coast as early as Friday or as late as Saturday Night, as well as whether it track up the coastal plain or offshore, as well as degree of intensification, and whether it acquires any tropical characteristics. NHC is monitoring the southern system for potential tropical or subtropical development this week, giving it a 30% chance over the next 5 days as it potentially emerges off the Carolina coast. Main threat with this low at this point would be a swath of heavy rainfall along its path as it taps into Gulf and subtropical Atlantic moisture, but low confidence on any details.

Better agreement that mean troughing will be sliding towards the east coast through the weekend, with a series of surface troughs moving through the area. Depending on timing of the southern wave, very warm and humid conditions are likely for the weekend, with threat of afternoon convection both days. Each successive trough Sunday into early next week, appears to bring in slightly cooler and drier airmass, but low predictability at this point.

AVIATION /00Z MONDAY THROUGH FRIDAY/. A weak cold front slowly drops south, eventually passing through the terminals toward daybreak Monday.

VFR. Winds will be variable to light WNW winds overnight give way to late morning/early afternoon sea breezes again on Monday. Showers and thunderstorms will be possible Monday afternoon/evening, mainly late in the afternoon.

OUTLOOK FOR 00Z TUESDAY THROUGH FRIDAY. Monday night through Thursday. Afternoon/evening showers and thunderstorms possible, mainly from the NYC metros north/west. Friday. Rain with sub-VFR more likely. Chc E-SE gusts 20-25kt.

MARINE. Sub-SCA conditions expected through mid week. Potential for SCA seas Friday into the weekend with a persistent S/SW flow and strengthening wind fields with a potential coastal low.

HYDROLOGY. Conditional and localized flash flood threat on Tuesday for far SW portions of the Tri-State, if a warm front nears or works into the region and interacts with a building moist and unstable airmass.

A localized urban and poor drainage flooding threat exists with any isolated thunderstorm activity Wed and Thu, as it will be slow moving and able to tap into a very moist environment.

There is potential for more widespread downpour/thunderstorm activity and resultant urban and poor drainage flooding threat during the Friday/Saturday period, but low confidence on details at this timeframe. More details as the week progresses.

TIDES/COASTAL FLOODING. The combination of a SE swell and high astronomical tides (full moon) will have water levels approach minor flood thresholds once again tonight, but they are expected to remain below minor flood benchmarks.

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