8/26/2020 The 7 day forecast is taking about 5 seconds to load but it will eventually load. NOAA is still working on it. 8/18/2020 NOAA continues to have trouble. Wind guest will occasionally be left off graphs. I am working with NOAA to resolve the issue. 12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed. 10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. |

SYNOPSIS. Weak surface low pressure to the north sends several weak cold fronts through the area by Friday night. High pressure builds in from the west Saturday and Saturday night, and settles over the region Sunday. The high weakens Monday as low pressure approaches. The low passes south of the area Monday night and Tuesday. High pressure returns for the middle of next week.
NEAR TERM /UNTIL 6 AM FRIDAY MORNING/. Winds decoupled and temperatures dropped during this evening, especially in the normally colder locations. Over the next few hours winds are expected to pick up slightly along with increasing cloud cover as another weak trough moves into the region and will affect the temperatures. Thus temperatures will likely rise again in the colder locations as mixing occurs.
During the overnight period, the low pressure to the north of the region will send another weak cold front through the area. This produces more in the way of clouds or some very light passing snow showers for northern portions of the CWA which should end by sunrise which has been handles with slight chance POPs.
SHORT TERM /6 AM FRIDAY MORNING THROUGH FRIDAY NIGHT/. More of the same for Friday with a mix of clouds and sun and the potential for some scattered flurries or sprinkles during the afternoon as the low pressure sends yet another weak cold front through the area. The additional mixing from daytime heating and the cold upper-levels thanks to the departing trough will allow for the development of a few convective showers of snow or rain, especially during the afternoon. High temperatures will be seasonable, generally in the low 40s.
Winds then shift more out of the NW by Friday night. The trough shifts eastward as strong high pressure starts to build into the area from the west. The pressure gradient tightens over the area allowing brisk winds with gusty conditions developing through Friday night and into early Saturday. Lows on Friday night will generally be in the 20s with some of the coldest spots dropping into the teens.
LONG TERM /SATURDAY THROUGH THURSDAY/. The northern stream will somewhat remain dominate and progressive through the weekend and into Monday. A ridge builds into the northeast and mid Atlantic coast by Sunday and then weakens as a northern stream trough moves into eastern Canada Sunday night and Monday.
A cold airmass will be in place for Saturday with a gusty northwest flow as temperatures are expected to be a few degrees below seasonal normals, with wind chills in the teens and lower 20s. Saturday night the gusty northwest flow gradually diminishes as the cold airmass remains and temperatures will be around 5 degrees below normal. Wind chill values will be mostly in the single digits.
Meanwhile a southern stream shortwave moves out of the southwest and quickly reaches the mid Atlantic coast Tuesday. There is some phasing of the northern and southern stream Tuesday into Tuesday night, however, the southern stream surface low will dominate as the surface low reaches the Ohio Valley by 00Z Tuesday. There remain some differences in the guidance with the timing and placement of another low developing off the mid Atlantic coast Monday night and tracking east into the Atlantic through Tuesday night. The trends remain to keep the low to the south of the area as arctic high pressure to the north noses down along the northeast coast. The ECMWF continues to be the furtherest north with the low, while the GFS and Canadian keep the precipitation shield across the southern portions of the forecast area. Will keep the probabilities at chance throughout the region for late Monday night through Tuesday. The airmass remains cold and precipitation is expected to be in the form of light snow.
Thereafter high pressure returns for later Tuesday into Thursday. And the is a chance another low moves south of the area late Thursday.
AVIATION /04Z FRIDAY THROUGH TUESDAY/. A weak cold front clears the area as it moves east overnight. A second cold front moves across Friday.
VFR. WSW-W less than 10 kt overnight. Gusts return late Friday morning with W winds.
NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty . Timing of gusts returning on Friday may be off by 1 to 3 hours.
OUTLOOK FOR 0Z SATURDAY THROUGH TUESDAY. Friday Night. VFR. WNW 10-15g20kt. Saturday. VFR. NW gusts 25-30kt. Sunday. VFR. WNW 7-15g20kt. Monday. VFR. NW-N Light. Tuesday. Chance of sub-vfr early in mixed precip or snow with NE gusts 20-25kt.

MARINE. The SCA for the eastern Long Island Sound, and the Long Island bays was allowed to expire as winds have decoupled and fallen well below 25 kt.
Small craft conditions on the oceans will persist through at least Friday night with gusty winds over 25 kt becoming more persistent through the day Friday and continuing into the night. The SCA for the ocean was extended through Friday night.
Small craft conditions will be on going for Saturday across all the forecast waters, with a strong northwest flow. There will even be a chance of gales across the eastern ocean waters late Saturday afternoon into the early evening.
High pressure will build in slowly from the west Saturday and Saturday night, and wind gusts will be gradually diminishing below SCA levels Saturday night through Sunday, with ocean seas below SCA by late day Sunday. Sub advisory conditions are then expected across all the waters from late Sunday night through Tuesday night as high pressure gradually weakens with approaching low pressure to the south.
HYDROLOGY. Mainly dry conditions are expected through the upcoming weekend. No hydrologic concerns are anticipated through the middle of next week.
