SYNOPSIS. An approaching warm front will lift to the north tonight. A cold front will then approach on Tuesday and slowly move across from Tuesday night into Wednesday. Arctic high pressure will then follow later in the week before another potential storm system arrives next weekend.

NEAR TERM /UNTIL 6 PM THIS EVENING/. Light rain ongoing attm from NYC east, with some patchy FZRA/PL on the leading edge in CT where some sheltered valley locations have remained below freezing. As additional rain spreads up from the south, may still yet have to watch the valleys or Orange County for the same as temps in spots along/north of I-84 are still hovering around 30.

Warm advection moderate rain will continue developing and spreading north through the morning hours and continue this afternoon, with the heaviest expected this afternoon across NYC and NE NJ and also across SE CT.

Temps on the mild side today, with highs in the 50s most places, perhaps close to 60 across eastern Long Island with the warm front approaching, upper 40s in western Orange.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM TUESDAY/. Warm front should lift north tonight, with a round of moderate- heavy rain likely for much of Long Island and SE CT. Enough elevated instability present to warrant mention of thunder for the forks of Long Island this evening with warm fropa.

Winds are a tricky forecast. Could see gusts 40-45 mph across the forks and the SE CT coast this evening, but an inversion may work to prevent stronger winds aloft from reaching the sfc except in heavier precip. Will handle via shorter fused products rather than issue wind advy.

Upper dynamics shift north of the area Monday night. The warm front should also lift north as the parent low pressure moves from the Great Lakes to southeast Canada. Rain will taper off from southwest to northeast around or just after midnight. Deep moisture and stronger forcing for ascent shift to the north and east after midnight with the rain tapering off from southwest to northeast. PoP drops off significantly overnight, but cannot completely rule out some lingering light showers. Showers pick up in coverage again Tue afternoon as a cold front enters the area.

Rainfall amounts through Monday night look to range from about 1-1.5 inches, locally closer to 2 inches in SE CT.

Temperatures will continue on the mild side, with temps remaining steady or only falling a couple of degrees tonight, then another mild day expected on Tue, with highs from the 50s to lower 60s, before quickly falling back into the 40s north/west..

Fog potential appears low at this time. However, it bears watching with dewpoints in the lower/mid 50s moving over SSTs in the upper 40s ad lower 50s.

LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/. Main impacts/forecast challenges this time frame will be post frontal precipitation Tuesday night into Wednesday, and the next system over the weekend. Much depends on placement of upper jet, and eventual evolution of the upper level trough during the mid week period.

Did not make too many changes to the long term period, Based on 00Z models. A lingering upper trough and placement of upper jet should result in a continuation of post frontal precip Tuesday night into Wednesday morning. A transition from rain to snow will occur Tuesday night into Wednesday morning as colder air advects in NW to SE. With lingering QPF of a quarter to a third of an inch around the time of transition, 1 to 4 inches of snow is possible across the area. Reasonable worst case scenario of around 6 inches is possible in spots away from the immediate coast. There is still plenty of time for change, so stay tuned.

Drier weather returns Wednesday afternoon through Friday as high pressure builds over the area. Expect Thursday to be cold with temperatures around or just above freezing.

WAA precip may arrive late Friday or Friday night from the south, but model differences in upstream trough remain, so confidence in exact forecast details such as timing and coverage of precip remains low. At this time, would generally expect wet weather Saturday (mainly rain), and possibly into Sunday although dry air advecting in from the west should result in lower rain chances Sunday.

Temperatures will warm to above normal late week and next weekend.

AVIATION /09Z MONDAY THROUGH FRIDAY/. Generally IFR this morning with an rain ahead of an approaching warm front. Behind the warm front, ceilings may improve to MVFR but confidence is not high enough at this time to go with the higher category. Rain could be moderate to occasionally heavy through this evening.

Light and variable winds will become E/SE toward daybreak ahead of an approaching warm front. S winds then ramp up late morning into the afternoon at 15-20 kt with gusts 25 to 30 kt along the coast. Isolated G35-40 kt possible. LLWS with SSW winds of 40-50 kt at 2kft.

OUTLOOK FOR 09Z TUESDAY THROUGH FRIDAY. Tuesday. MVFR or lower conds in showers. SW gusts around 20 kt possible. Winds shift to the NW with gusts 25-30kt with a cold frontal passage in the late afternoon/evening. Tuesday Night into Wednesday. MVFR or lower with rain in the evening, likely becoming IFR or lower transitioning to sleet then snow late Tuesday Night, continuing into Wednesday morning push. W- NW G20-25kt possible. Potential for light snow accumulations. Snow ends Wednesday afternoon with conditions improving to VFR. Thursday into Friday. VFR.

MARINE. Will be delaying gale warning for the ocean waters W of Fire Island til tonight, with the main push of stronger winds to the east today, and gusts in S-SW flow getting close but not quite to 35 kt except on the ocean E of Moriches Inlet this afternoon.

Winds should pick up with warm fropa, and gale warning remains in effect for all the ocean waters during this time, and SCA conds on the remaining waters.

The front passes through the area Tuesday night with marginal SCA gusts possible Wednesday into Thursday morning in a W-NW flow. Seas however will remain above 5 ft through this period, so SCAs can be expected on the ocean.

Winds diminish and seas subside quite a bit Thursday afternoon and Thursday night.

There is the potential for another storm system to impact the waters at the end of the week.

HYDROLOGY. A long duration precipitation event is expected from late tonight into Wednesday. The precipitation late tonight into Tuesday will be in the form of plain rain. The precipitation transitions to frozen Tuesday night into Wednesday morning. Total liquid equivalent precipitation of 1 to 2 inches is forecast. Nuisance/poor drainage flooding may occur on Monday afternoon and Monday night when the heaviest rain falls.

Next significant rain of at least a half an inch is expected by the weekend. Too early to ascertain hydrologic impacts.

EQUIPMENT. NYC NOAA Weather Radio Station KWO35 (162.55 MHz) is still operating at reduced power.
