SYNOPSIS. Low pressure system north of Maine meanders over eastern Canada through Friday as a high pressure over central Canada dives south into the Great Lakes region. The high will build over the region Sunday and remain in control Monday, and then shift to the south and east into the middle of next week. The high moves offshore Wednesday night and Thursday as a cold front slowly approaches from the west.
NEAR TERM /THROUGH TODAY/. Forecast is generally on track. Just a few minor adjustments with respect to winds over land, thus adjusted up with winds for the next few hours.
High pressure north of the Great Lakes Region continues to force dry air from the northwest into the local area. Winds around 15-20 mph drive dew points down from the teens into the single digits overnight. Likewise a chilly night is in store as ambient temperatures fall into the low 20s and upper teens. Sky cover remains rather clear with possibly some mid-level clouds creeping in prior to sunrise as a weak reinforcing cold front pushes south into Long Island.
SHORT TERM /TONIGHT THROUGH 6 PM SATURDAY/. Trough north of Maine remains quasi-stationary through Friday with dry conditions dominating for the day. As the surface low over eastern Canada slowly fills, the high pressure system over central Canada nudges south following the upper level southwesterly flow. Locally this maintains and even slightly strengthens the pressure gradient over the Northeast states and northwest winds over souther New York remain stable 15-20 mph with gusts up to 30 mph. Temperatures by the afternoon will be around 10 degrees colder on average that the day prior settling back in the mid to low 30s. Additionally, wind chills will make it feel like the low 20s even with clear skies.
As the Sun sets expect winds to decouple and gusts to come to a end for the evening. The relaxing winds and end to the mixing should allow dew points to slightly recover overnight. This does help overnight minimums which are expected to be in the mid to low 20s throughout the area.
LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/. Upper ridging will be building into the eastern U.S. beginning Saturday, as a deep closed upper low over eastern Canada and the northeast weakens and slowly tracks east, and continuing into Wednesday. A cool airmass will remain over the northeast Saturday with weak cold advection gradually ending into Saturday night. With surface high pressure to the west Saturday, a gusty northwest flow will dominate, and temperatures will remain up to 10 degrees below normal. Deep northwest flow will continue Saturday night through Sunday night as heights slowly rise with the approach of the ridge axis. Below normal temperatures are expected into Monday, however, weak warm advection begins to setup during Monday as low level winds gradually back, and a warming trend begins. The warming will then continue into the end of the week, with stronger warming expected Wednesday and Thursday as the surface high and upper ridge begin to move offshore. By Thursday temperatures may be as much as 10 to 15 degrees above normal seasonal levels. The southwesterly flow that does set up Tuesday through Thursday will keep temperatures along the coast several degrees lower as ocean water temperature remain in the lower 40s. A frontal system will be approaching for Thursday, however, the trend has been for the eastern ridge to be slower to move offshore as the trough deepens across the central U.S. As a result, will have low to slight chance probabilities for Thursday, with the possibility of Thursday remaining dry.
AVIATION /07Z FRIDAY THROUGH TUESDAY/. VFR with gusty NW winds as the region remains between high pressure over the Midwest and low pressure over the Canadian Maritimes.
NW winds 15-20G25-30kt, which may lull somewhat to 15-20G20-25kt right before the into the AM push, then pick up again to 15-20G25- 30kt, while shifting slightly right of, on, or just left of 310 mag.
. NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty .
Occasional gusts around 30-35 kt are possible through 09z.
OUTLOOK FOR 06Z SATURDAY THROUGH TUESDAY. Friday night and Saturday. VFR. NW winds 10-15G20kt. Saturday night through Tuesday. VFR.

MARINE. With the gusty winds, elevated seas, and low temperatures expected later tonight into Friday morning, updated to add a chance of light freezing spray to the ocean waters and eastern Long Island Sound.
Persistent SCA criteria offshore winds remain through the short-term forecast. Particularly offshore gusts between 25-30 kts are expected through Saturday morning. Waves are anticipated to hold around 4 feet through late Friday before beginning to wane possibly Saturday morning.
Small craft advisory wind gusts will be possible across all the forecast waters Saturday morning as deep low pressure continues to meander through the Canadian Maritimes and high pressure builds to the west. In addition, ocean seas will be subsiding to below 5 feet in a west to northwest flow. Conditions will be gradually improving through Saturday from west to east, as high pressure builds toward the waters from the northwest. There is some uncertainty as to how quickly the high builds toward the forecast waters, and SCA conditions may linger into late Saturday. After Saturday tranquil conditions are expected into early next week as high pressure dominates.
HYDROLOGY. The dry weather regime will continue, thus there are no hydrologic concerns into the middle of next week.
