SYNOPSIS
High pressure builds down the New England coast through Friday.
The high retreats farther offshore on Saturday as a frontal system approaches from the west. This system moves slowly through the region Saturday night into Sunday with the associated cold front passing through Monday. The front then stalls south of the region and moves back north as a warm front Tuesday into Wednesday. A cold front approaches for Thursday.

NEAR TERM /THROUGH THIS AFTERNOON/
The forecast remains on track. Surface high will build down from eastern Canada and along the New England coast. NE winds will advect in moist Canadian maritime airmass under a subsidence inversion, which should allow for advection of stratus late east to west for the late night hours.

Stratus then erodes during the morning hours, but some cirrus will be around. Highs then warm up into the upper 50s and lower 60s along the coast, and 65-70 inland. This is slightly above normal.

SHORT TERM /TONIGHT THROUGH SATURDAY/
High pressure gradually retreats offshore during this time as a slow moving frontal system approaches from the SW. This will allow for increasing clouds Friday night into Saturday. ESE winds will continue during this time with temperatures remaining several degrees below normal, in fact it will be cooler for inland area versus the previous day due to increase in clouds and onshore flow. Warm advection could bring a few showers in late in the day, mainly north and west of NYC.

LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/
An upper level ridge axis shifts offshore late Saturday night into early Sunday and the flow becomes near zonal into early next week. A longwave upper trough across eastern Canada amplifies into the northeast Tuesday and moves offshore by Wednesday as another upper ridge builds to the west of the area and moves into the region, while beginning to flatten, Wednesday. The upper flow again become nearly zonal as a tough becomes sheared out across the northern plains and Great Lakes region Wednesday night into Thursday. At the surface one frontal system slowly approaches from Saturday night through Sunday, while slowly weakening, as the system moves into the upper ridge. Another system passes well to the north with its cold front passing through the region Monday. The trend for these systems Saturday night through Monday as be slower as the upper ridge over the western Atlantic remains highly amplified. The stalled frontal boundary to the south begins to track north as a warm front Monday night and is expected to the north during Wednesday. The area remains warm sectored Thursday as low pressure over the northern plains become sheared. Temperatures will be near to below normal Saturday night into Sunday, then average above normal Sunday night through Thursday, with the warmest days being Wednesday and Thursday. Generally followed the NBM guidance, and for the days with higher temperature spreads, and potential for warmer conditions blended the NBM and 75th percentile. There is still a possibility that a few locations could set record high minimum temperatures Tuesday morning.

AVIATION /06Z FRIDAY THROUGH TUESDAY/
Behind a cold frontal passage overnight, weak high pressure builds in through Friday.

VFR to start, though MVFR stratus likely works in into early this morning behind a backdoor cold frontal passage. Gradual improvement to VFR from E to W in the early to mid afternoon.
Cigs may fall once again into early Sat AM with potential stratus development.

NE flow has developed behind the front with speeds increasing to around 10 kt and gusts toward 20 kt developing by 9Z or so.
These gusts should continue thru morning push before gradual abatement. Winds continue to veer to the E/SE in the afternoon.
SE winds subside less than 10 kt thru aft/eve push.

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

NE gusts of 15 to 20 kt may be more occasional during AM push.

Timing of windshift, and stratus development/dissipation may be off by a couple of hours.

OUTLOOK FOR 06Z SATURDAY THROUGH TUESDAY...

Late Friday Night: VFR. Low chance of MVFR stratus toward morning.

Saturday: Mainly VFR. Low prob of patchy early AM MVFR stratus.
Slight chance of showers and MVFR conditions in the afternoon, increasing chances overnight.

Sunday...Likely showers, with MVFR or lower conditions. ESE winds G15-20kt.

Monday...VFR.

Tuesday... Mainly VFR. Chance of MVFR showers.
