Synopsis for the long island waters and new york harbor.. A warm front moves through overnight. Low pressure then develops to the southwest into Wednesday. The low is expected to move over the area Wednesday night, as a cold front approaches from the north in advance of building high pressure over new england. The cold front moves through Thursday, followed by building high pressure that will remain centered over the southeast into the weekend. Another weak cold front moves slowly through the area Saturday night. The front stalls to our south Sunday with a wave of low pressure developing along it.

Low pressure then develops to the southwest into Wednesday. The low is expected to move over the area Wednesday night, as a cold front approaches from the north in advance of building high pressure over new england. The cold front moves through Thursday, followed by building high pressure that will remain centered over the southeast into the weekend. Another weak cold front moves slowly through the area Saturday night. The front stalls to our south Sunday with a wave of low pressure developing along it possibly impacting the region early next work week. Near term until 6 am Wednesday morning Pops increased for orange county mainly for showers and thunderstorms. One complex of showers and thunderstorms is moving northeast of orange county, leaving just some showers across orange county through mid evening. A warm front will move through tonight, and with cloud cover as well as continued SW flow allowing for warm air advection, muggy conditions will return. Forecast temperatures only fall to the low to mid 70s, and dew points return into the upper 60s to lower 70s. Otherwise, not expecting much shower and thunderstorm activity for the remainder of tonight as instability decreases with decreasing temperatures in agreement with mesoscale models showing a decrease in reflectivity after 00z. Temperatures are relatively warmer along the coast and with warm air advection and more moist low level environment, instability is more across the coast for overnight. Therefore did not go totally dry and kept the slight chance of showers and thunderstorms for the region for late tonight into early Wednesday. A weak convectively induced vorticity maximum upstream is expected to pass through tonight, which combined with the warm front may lead to isolated thunderstorms overnight. Timing and placement of any showers and thunderstorms will be difficult to pinpoint, but with increased moisture a brief heavy downpour may be possible as well. So with this forcing and the warm front boundary that will be moving through, so there are enough factors there to keep a slight chance of showers and thunderstorms in the forecast. Short term 6 am Wednesday morning through Wednesday night Heights will fall on Wednesday as an upper trough to the north phases with a short wave trough containing the remnants of tropical cyclone barry. Despite an associated increase in cloud cover, strengthening west-southwest flow will lead to continued warm advection, with temperatures rising into the 80s to lower 90s. Expect uncomfortable conditions, with a few locales in northeastern nj and nyc achieving heat indices in the afternoon around 95 degrees as dew points remain in the low to mid 70s. The quick increase in temperatures will also allow any remaining cinh to erode by afternoon, and between a thermal trough developing across the interior and sea breezes near the coast, there may be enough forcing for ascent for thunderstorms to develop at any time. Most shower and thunderstorm activity will develop by late afternoon into the evening as the trough nears and a surface low deepens across the coast. The remnants of barry will bring a significant increase in deep layer moisture, with forecast pwat values well in excess of 2.00-2.25". Although weak mid level lapse rates may limit updraft strength, low level lapse rates are expected to steepen, with dcape values in the 500-1000 j kg range, a subtle increase in low level flow, and evaporative cooling likely supporting downdrafts in storms that do develop. Additional storms will likely be triggered along the subsequent outflow boundaries. Expect heavy downpours and potentially strong to severe wind gusts in any storms that develop. Storms then develop into a complex or complexes overnight as flow aloft becomes parallel to the developing surface low. |
Training of storms and convective nature may lead to an enhanced threat for localized flooding as well. Refer to the hydrology section for more information. Muggy conditions will continue Wednesday night as lows only fall into the 70s, and dew points remain in the 70s as well. There is a moderate rip current risk at the ocean beaches for Wednesday. Long term Thursday through Tuesday Weak low pressure associated with the remnants of barry shifts through the area on Thursday. Model average suggests that the the center of this passes over or just to our south. This in turn brings the wind forecast trend more towards an east to east-northeast direction. Even if this doesn't pan out, plenty of cloud cover should prevent temperatures from rising as high as previously forecast. Won't go with a mav met blend just yet for high temps, but will trend towards that direction. Regarding rainfall potential, the general trend will be for chances lowering as the day progresses with the low drifting east. Pwats in this airmass will be high at the start of the day - perhaps near 2.5 inches. This, combined with a light steering flow presents at least a low chance of flash flooding with heavy rainfall. Rain chances continue to diminish through Thursday night with the low moving farther out to sea. Dry weather is expected by sunrise. Heights aloft build on Friday along with surface ridging. Models show some subsidence with some capping along with relatively low moisture. Will go with a dry forecast. The subsidence will also have impacts on high temperatures. Looks like mixing would be limited to 900mb. Highs therefore reaching the mid 90s for the urban corridor of NE nj, lower 90s for the city and lower hudson valley, and 85-90 for most of LI and ct. All models show a band of 6-12c 850mb dewpoints shifting through during the late morning to mid-afternoon hours. This would promote lowering surface dewpoints with mixing of the boundary layer, however the surface flow will be sw, offsetting this. Still think surface dewpoints could mix out a little. This leads to maximum heat indices averaging in the upper 90s to around 100 for all but ct and most of li. Mixing to 850 mb is more probable on Saturday, and temps at this level are expected to average around 23c. 850mb dewpoints will be higher this time, around 14-17c, making it more difficult for surface dewpoints to lower, but this could be offset by more of a wsw surface flow. Expecting highs around 100 for NE nj, and some locations within the city, and 90s elsewhere. Heat index values will likely reach at least advisory levels everywhere, and a good portion of the forecast area could potentially reach warning levels. Dry weather should continue with relatively low rh through the atmospheric column. A weak cold front is progged to move through late Saturday night, but this will do little to send any relief from the heat. 850mb temps progged at 21-22c with a westerly flow could have temperatures getting to near 100 once again for some areas on Sunday, but for now will go with highs mostly in the mid to upper 90s. Some areas could reach heat warning levels once again, and most areas would probably reach advisory criteria. A wave of low pressure moves in on Monday, with a chance of showers and thunderstorms along with highs in the upper 80s to lower 90s. Tuesday looks dry for now with highs a few degrees cooler than on Monday. Aviation 00z Wednesday through Sunday Vfr through Wednesday afternoon. Light southwest winds tonight, increasing Wednesday morning to 10 to 15 kt. Southerly coastal sea breezes likely Wednesday afternoon. Isolated showers and thunderstorms moving into orange county should dissipate before reaching the nyc nj metro terminals, showers and thunderstorms are possible well north and west of nyc tomorrow afternoon. Showers and possible thunderstorms likely for nyc nj metro after 22-00z as weak low pressure and the moisture remnants of barry approach from the west.
