SYNOPSIS
Coastal low pressure tracks up the Atlantic coast and passes east tonight and into Friday. A series of weak waves of low pressure will track close to the area Saturday night into early next week. A deepening area of low pressure will then track across the Lower Great Lakes region Tuesday into Tuesday night, becoming nearly stationary across the Northeast for the middle of next week. The associated frontal system will impact the area during this time.
NEAR TERM /UNTIL 6 AM FRIDAY MORNING/
A secondary cold front is slowly moving through the area allowing for a focus for a plume of moisture ahead of a coastal low to advect into the area. A jet streak over the area and down stream of the approaching trough is providing for ample deep level ascent which is providing for widespread rainfall to continue into tonight.
Though rain has lessened in intensity for western portions of the area, another wave of moisture will make its way into the region on the northwestern side of the approaching coastal low. This will allow rainfall to fill back in by this evening and persist through much of the first half of the night. Rain should then slowly continue to end from west to east into the early morning hours as the coastal low pushes into the Canadian Maritimes.
Lows tonight will be in the middle to upper 30s for much of the area.
SHORT TERM /6 AM FRIDAY MORNING THROUGH FRIDAY NIGHT/
The coastal low continues to progress further northeast into Southeast Canada with high pressure building in from the west into Friday. This will allow for gradually clearing skies during the day Friday. The tight pressure gradient over the area on Friday will also allow for gusty NW winds to develop, possibly upwards of 30-35 mph, especially near the coast. Highs on Friday will be in the low to middle 50s.
Gusty NW flow continues Friday night as weak high pressure continues to move in from the west and the strengthening low pressure to the northeast moves into Southeast Canada. Winds will begin to relax a bit late in the night and into early Saturday. Lows will be in the low to middle 30s for inland areas with temps near 40 for the NYC metro.
LONG TERM /SATURDAY THROUGH THURSDAY/
A nearly zonal flow at the start of the period will allow for multiple waves of low pressure to track close enough to the area for chances of mainly light rain. The first of which will bring in a low chance for rain late Saturday afternoon and night, followed by weak high pressure on Sunday. Another wave passes to the south Sunday night into Monday, with another shot of weak warm advection rain. A cutoff low over the Great Basin then gets kicked eastward out into the Northern/Central Plains Monday, and then across the Great Lakes Monday night into Tuesday. This will be associated with a deepening surface low that sends a warm front toward the area Monday night into Tuesday, followed by a cold frontal passage on Wednesday. There are differences in the globals in the timing and evolution of the energy that lifts out of the intermountain west, but there are commonalities with an overrunning rain during this time. It also looks like the area remains north of the warm front, but could come close with marginal instability and perhaps some embedded convection Tuesday night. It's too early to be too specific with the details. Digging jet energy across the Great Lakes on Wednesday leads to a closed off upper low that tracks into the Northeast.
Cyclonic flow and the potential for secondary low formation in the vicinity of New England would keep clouds and low chances of precipitation into Thursday.
Temperatures will be several degrees above normal over the weekend with daytime highs in the mid and upper 50s, with lows in the upper 30s inland, and in the 40s at the coast. Unsettled conditions and easterly flow to start the week will result in cool, damp conditions with temperatures at or just below normal for highs, but slightly above normal for lows due to cloud cover.
AVIATION /20Z THURSDAY THROUGH TUESDAY/
A cold front eventually gives way to low pressure offshore moving northeast during the TAF period.
Rain will linger across most of the terminals into the evening. Rain may occasionally pass by KSWF with much of it to the SE by this evening, so mainly dry conditions anticipated there. For much of the rest of the terminals, the rain will taper off late tonight from west to east. KGON will have some rainfall early Friday morning before the rain tapers off there for latter half of Friday morning.
MVFR ceilings will continue through the rest of this afternoon into early evening for most terminals except for KISP and KGON where IFR will be more likely. For tonight, eventual improvement to VFR expected for all terminals except east of NYC terminals for KISP and KGON where mainly IFR will continue. KISP has improvement to MVFR late tonight and for KGON, improvement to MVFR early Friday morning.
Winds will be northerly near 10 kt this afternoon. Tonight into Friday, winds will be more NW. The wind speed increases to 10-15 kt this evening, and then increases to 15-20 kt overnight into Friday.
Gusts develop this evening to near 20 kt and then mainly in the 25- 30 kt range overnight into Friday.
NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...
Low chance of IFR before 00Z. Gusts to 20 kt could develop 1-2 hours earlier than forecast.
OUTLOOK FOR 18Z FRIDAY THROUGH MONDAY...
Friday: VFR. NW wind gusts 20-25 kt.
Saturday: Mainly VFR during the day. Chance of showers and MVFR at night, possibly mixed with snow for KSWF. W wind gusts near 20 kt day. Gusts diminish at night.
Sunday: Mainly VFR. NW wind gusts 15-20 kt afternoon into early evening.
Monday: MVFR possible with a chance of showers.
Tuesday: Rain with MVFR or lower conditions. E wind gusts near 20 kt.

MARINE
Winds increase tonight as a low pressure system approaches the area from the south. Gusts will be 25-30kt over all waters tonight and through much of the day Friday so a Small Craft Advisory is in effect for all waters. While there may be an occasional gust to 35 kt on the ocean tonight, gusts will not be widespread enough to warrant a gale warning.
Strong wind gusts of up to 30 kt will be possible for all waters through Friday afternoon. Winds may increase a bit by Friday evening such that near gale force gusts will be possible on the ocean zones.
A Gale Watch is in effect for 00Z Saturday through 10Z Saturday. All other waters will see SCA conditions with gusts up to 30 kt.
SCA conditions will linger on the ocean waters into Saturday behind departing low pressure over the Canadian Maritimes.
Elsewhere, brief SCA gusts are possible in the morning. Winds and seas will gradually subside through the day with sub-SCA conditions likely by evening. The next chance for a SCA will be on Tuesday in a strengthening easterly flow.
HYDROLOGY
Up to another inch of rainfall is possible tonight across the eastern half of the CWA This should not provide for any hydrologic impacts.
Otherwise, no hydrologic impacts are expected through the end of the week.
