SYNOPSIS. A front remains nearly stationary south of Long Island, gradually dissipating into Friday. Low pressure well south of Long Island on Friday will be moving northeast within the Western Atlantic through the weekend, passing well southeast of Long Island. Meanwhile, a weakening cold front approaches the local region Saturday with high pressure eventually taking over for the latter half of the weekend into early next week. The high pressure area will start moving offshore by the middle of next week.

NEAR TERM /UNTIL 6 PM THIS EVENING/. A frontal boundary remains south of Long Island this afternoon with thunderstorms along the boundary where convergence is occurring. Otherwise showers and isolated thunderstorm will be possible this afternoon as daytime heating peaks. With the scattered nature and low probabilities have kept with the coverage wording. Much of the day will remain nearly overcast across the region.

With high moisture content, around 1.75 inches of precipitable water, any thunderstorm can produce locally and briefly heavy rainfall which may result in nuisance and poor drainage flooding. Slow movement of storms if persistent enough may produce a more substantial flood concern, as such, WPC has much of the area in a marginal risk for excessive rainfall today. The highs today will be in the middle to upper 70s.

SHORT TERM /6 PM THIS EVENING THROUGH FRIDAY NIGHT/. Any stronger storms this evening gradually weaken though there will remain a chance for showers through much of the overnight period with onshore moist flow interacting with the stalled frontal boundary. Lows tonight will be in the middle to upper 60s.

The models remain coherent in their forecast depiction of a low off the coast of Carolinas. While the National Hurricane Center continues to indicate potential tropical development of this low, the models indicate a track of the low that passes southeast of the 40N/70W benchmark late Friday night and continue to track northeast farther away from the region for the upcoming weekend.

For Friday, with a narrow upper level jet streak off the coast of New England and right rear quadrant near the region, along with positive vorticity advection in the mid levels, there will be factors for lift during the day. These factors shift farther east Friday night eventually leaving the region. The surface pressure gradient between an offshore low and high pressure in the Canadian Maritimes will lead to easterly flow. With some frictional convergence and aforementioned factors aloft, there will be chances for showers through the day and into early evening and with weak instability, a slight chance for thunderstorms. Chances for showers lower Friday night with mainly dry conditions getting reestablished from west to east. Across the interior, with low level moisture, cooling of temperatures, and lighter winds, patchy fog is expected to develop Friday night into early Saturday morning.

LONG TERM /SATURDAY THROUGH WEDNESDAY/. For Saturday, a weak cold front approaches from the west. There will be a slight chance of showers and thunderstorms across Northeast NJ, Lower Hudson Valley, NYC, western parts of Long Island as well as Southwest Connecticut. These locations will be closer to the cold front and will be warmer and therefore more unstable relative to locations farther east.

For Saturday night into the rest of the weekend, high pressure will return and become established across the Northeastern Seaboard with dry weather forecast. A trough aloft and associated upper level jet will help accelerate the low in the Western Atlantic farther northeast, getting to a vicinity of southeast of the Canadian Maritimes.

Ridging increases Sunday night into early next week with high pressure at the surface remaining along the Northeastern Seaboard. This will be a large ridge of high pressure so expecting the weather to remain dry with subsidence from the high pressure. The high pressure area will start moving more out into the Atlantic by the middle of next week. Weather will remain mainly dry.

Temperatures are not much different from previous forecast with high temperatures averaging a few degrees above normal during the long term. One exception is Saturday with the relatively highest temperatures of the long term period, getting near 5 degrees above normal, as max temperatures reach more into the lower 80s.

AVIATION /15Z THURSDAY THROUGH TUESDAY/. A stationary front remains just off to the south of the terminals today.

Mostly VFR to start, but bcmg MVFR into this aftn. Showers this afternoon, and potentially additional showers this evening. IFR conds expected late tonight. Can't completely rule out a thunderstorm at any point today, but confidence is too low to include in TAFs at this time.

NE to ENE winds 10-15 kt.

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

Timing of flight category changes could be off by an hour or two. Timing of prevailing shra might be off by 1-2 hours as well. It's also possible prevailing shra does not occur today.

The afternoon KJFK/KLGA/KEWR haze potential forecast is RED . which implies slant range visibility less than 4sm outside of cloud.

OUTLOOK FOR 12Z FRIDAY THROUGH MONDAY. Friday. MVFR with a chance of showers and slight chance of tstms. Saturday-Monday. VFR.

MARINE. The line of thunderstorms along the stalled frontal boundary have moved to just south of the forecast waters. No changes were made at this time to the forecast waters winds, seas, and weather.

Sub SCA conditions are expected into late tonight, though seas start building over the ocean waters around daybreak Friday.

Residual higher ocean seas of near 5 to 6 ft are forecast that will keep ocean with SCA level seas Friday into Saturday with otherwise sub-SCA conditions for non-ocean waters. Conditions are below SCA criteria for all waters by daybreak Sunday through early next week as strong high pressure moves across the waters, making for a weak pressure gradient.

HYDROLOGY. Showers and possibly a thunderstorm cannot be ruled out today. A few downpours are possible which may lead to nuisance minor urban flooding, however, the best chances for heavy rain is over the ocean, along a stalled frontal boundary.

TIDES/COASTAL FLOODING. There will be a moderate risk of rip currents today for the ocean beaches with 2 to 3 ft ocean seas with residual southerly swell and E-SE winds of near 10 kt. For Friday, ocean seas will be building to 5 to 6 ft with more of an easterly swell and winds will be E-NE near 10-15 kt, making for a high risk of rip currents for the ocean beaches.
