.NEAR TERM /THROUGH TONIGHT/...
-- Changed Discussion --
Raised high temperatures a few degrees in some spots to reflect the current observations and trends of temperatures into the afternoon. Parts of the NYC metro are already into the low 80s with much of the area`s temperatures continuing to increase into the afternoon. Any clouds have diminished and pushed offshore and the rest of the day looks to remain mostly sunny. Temperatures will also continue their gradual ascent as 850 mb temps work to 10 to 12 C late in the day. With more in the way of sunshine towards the afternoon expect max temps on more of a offshore flow from the W and WNW to get into the upper 70s and lower 80s from NYC on west and well inland, to mainly 70s elsewhere, and a few 60s across far eastern coastal sections. This will get most places to 20 degrees above the seasonal averages, with somewhat lower departures from normal along eastern coastal sections. With abnormally dry air remaining in place and breezy conditions the risk of fire spread will remain high over a relatively larger area. Refer to the fire wx section for details. For tonight as the air mass in place continues to gradually warm temps will remain rather mild and a few degrees warmer in all likelihood from the previous night under a mainly clear sky. Enough of a westerly synoptic flow should preclude the formation of a marine layer with low clouds from attempting to push in most places. Out towards eastern LI the chances of a stronger maritime intrusion will be higher as temps could get down to around 50, or a few upper 40s for lows. Otherwise, lows will range from the lower 60s in the NYC metro, and mainly 50s elsewhere. See the climate sections with regard to any records through the period.

&& .SHORT TERM /THURSDAY THROUGH FRIDAY/...
-- Changed Discussion --
The trend up in temperatures continues into the latter portion of the week for Thursday and Friday. Global guidance consensus has 850 mb temps warming to about 14 C on Thursday, and 15 to 16 C on Friday. This will translate to day time maxes getting well into the 80s across the interior and away from the coast. Otherwise, a hybrid coastal sea breeze may have a better chance of getting going on Friday, with the winds during the day on Thursday likely maintaining more of a westerly component, even for some coastal communities for a good portion of the day. Low to mid 80s look likely for the NYC metro, with perhaps southern portions of the city down into Brooklyn staying in the upper 70s, with cooler lower and middle 70s for eastern sections. Some coastal communities may hit 80 towards mid day on Thursday, before localized sea breezes can get initiated. Night time conditions look to be similar for Thursday night. Southeastern coastal sections will cool down the most due to localized sea breezes setting up earlier in the night. Otherwise, look for lows to be mainly in the middle 50s to lower 60s which continues the run of well above normal temperatures. See the climate sections with regard to any records through the period.

&& .LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/... Increasing cloud cover and rain chances over the weekend will put a damper on the record warmth across the region, however, it will remain unseasonably warm. Record Min Maxs are still a possibility Friday night with a mild southerly flow and increasing cloud cover. For Saturday, highs are forecast to be 10-15 degrees above normal, but on the downward trend. This will also hinge on the extent of cloud cover increasing ahead of a southern branch low moving around the western periphery of the ridge over the western Atlantic. The latter which will bring a chance of showers Saturday into Saturday night. A stronger frontal system will then approach the area on Sunday and move through the area Sunday night into Monday morning. There is a good chance of showers at this time. Instability is marginal and will leave the mention of thunder out at this time. Behind the front, temperatures will return to more seasonable levels to start the week. In addition, global models are also in good agreement with closing off an upper low across the NE quarter of the nation, keeping the weather unsettled with a chance of showers. && .AVIATION /18Z WEDNESDAY THROUGH MONDAY/... A weak cold front stalls near or just NE of the area this morning and then slowly lifts NE through tonight. High pressure will remain south of the area. VFR. W to NW winds will increase to 10 to 15kt G20-25 kt this morning. Winds and gusts increase, with higher confidence in frequent gusts developing. Timing of the ending of the gusts late this afternoon is uncertain and gusts may continue an hour or two later. ...NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty... Winds at KJFK may stay 10-20 degrees to the right this afternoon. Direction will be mainly left of 310 magnetic. Timing of the ending of the gusts late this afternoon may vary by 1-2 hours. ...OUTLOOK FOR 12Z THURSDAY THROUGH SUNDAY... Thursday through Friday: VFR. Saturday: Chance of MVFR in showers late. Sunday: MVFR or lower possible in showers. Detailed information, including hourly TAF wind component forecasts, can be found at: https:/www.weather.gov/zny/n90. && .MARINE... SCAs have been cancelled for all zones except the easter ocean for seas near 5 ft. While there may be a few near-shore gusts to 25 kt through this afternoon, they`re expected to be occasional and not widespread enough to warrant an extension of the advisory. Sub-SCA conditions return for all waters later today into tonight. More tranquil conditions are expected on Friday with seas for a time only averaging around 2 ft on the ocean. Sub SCA conditions are expected through most of the weekend, with a weak pressure gradient over the area and high pressure over the Western Atlantic largely remaining in control. && .FIRE WEATHER... With the extended period of dry weather continuing and daytime min RH values at 25 to 30 percent and wind gusts to around 25 mph at times for today , a red flag warning has been issued for CT, with an SPS for NE NJ and all NY zones (NYC, LI, and the Lower Hudson Valley) for today. Conditions are expected to be marginal on Thu, and will be reevaluated later today and tonight. && .HYDROLOGY... No hydrologic concerns exist into early next week. && .CLIMATE...
