Synopsis for the long island and connecticut coastal waters.. The area will reside under weak high pressure today between frontal systems located to the north and south. Developing low pressure over the mid mississippi valley tonight heads up into the great lakes through Sunday, with a secondary low developing to the south of the area. Both lows lift north and east of the area Sunday night into Monday dragging a cold front through the area. High pressure returns for Tuesday. Another wave of low pressure develops off the middle atlantic coast Wednesday.

SYNOPSIS
The area will reside under weak high pressure today between frontal systems located to the north and south. Developing low pressure over the Mid Mississippi Valley tonight heads up into the Great Lakes through Sunday, with a secondary low developing to the south of the area. Both lows lift north and east Sunday night into Monday, dragging a cold front through the area. High pressure returns for Tuesday. Another wave of low pressure develops off the Middle Atlantic coast Wednesday, followed by high pressure for Thursday. The next frontal system may approach next Friday.
NEAR TERM /UNTIL 6 PM THIS EVENING/
Just minor update to current observations based on latest trends. Otherwise, forecast remains on track.
An amplifying shortwave trough over the Plains today will become a player later tonight into Sunday, but in the meantime the forecast area will reside under weak high pressure. A weak cold front sags south across the the Northeast today, while another frontal system offshore will be stalled to the south and east. After some morning clouds and fog, there very well could be some breaks in the cloud cover. For the time, highs are forecast to be mainly in the lower to mid 50s, but a few warmer readings are possible, especially if more sun is achieved. Wind will light W/SW.
SHORT TERM /6 PM THIS EVENING THROUGH MONDAY/
A confluent upper flow across eastern Canada, ahead of an amplifying trough over the mid section of the country, will allow for high pressure to remain in place across eastern Canada. This will allow a dissipating cold front to get close to the area tonight or pass just to the south. Lows will be mild in the 40s. At the same time, an amplifying shortwave trough lifts across the Mid Mississippi Valley tonight and across the Great Lakes on Sunday. At the surface, developing low pressure follows a similar track with a secondary low developing to the south of the area on Sunday. A deep SW flow aloft and strengthening low-level easterlies across the area will allow for a decent overrunning rain event starting late tonight and continuing through much of the day Sunday before drying out at night. Rainfall amounts across the area will average between 0.75-1.00". East winds and rain will keep temperatures on Sunday from getting any higher than the upper 40s inland and the lower 50s along the coast.
A double-barreled low structure from the eastern Great Lakes to east of New England will lift north and east Sunday night into Monday with drying conditions and a gusty west flow to follow.
Modest cold advection follows with temperatures returning to more seasonable levels.
LONG TERM /MONDAY NIGHT THROUGH FRIDAY/
High pressure briefly returns for the forecast area Tuesday. A weak surface low dives south from the Northern Plains into the mid-West Monday night, while the flow aloft within the upper trough begins to amplify Tuesday into Tuesday night as energy is progged to dive southeastward towards the coast. Additionally, a weak cold front or surface trough moves through Tuesday. This surface feature will move through dry. The surface low weakens as it passes south and west, with a secondary low developing off shore by Tuesday night. A large majority of the global models and ensembles keep the secondary low pressure development well south and east off the Middle Atlantic coast late Tuesday night into Wednesday. However, there are some ensembles members that have an inverted trough near the area or the low close enough to support a slight chance (20 percent) PoP. Based on the currently modeled pattern, the upper trough amplification occurs too far offshore for any impacts to the region. Temperatures Tuesday will be in the lower to middle 40s and then only upper 30s to middle 40s on Wednesday.
The mean upper trough should push offshore later Wednesday into Thursday. The deterministic runs diverge for the end of the week, but ensemble means indicate a near zonal flow aloft with some potential of a frontal system to approach on Friday. The forecast remains dry with surface high pressure largely in control. Highs in the upper 30s to lower 40s Thursday trend closer to normal on Friday.
AVIATION /16Z SATURDAY THROUGH WEDNESDAY/
The area will reside under weak high pressure between multiple frontal systems today. Another low tracks west of the area late tonight into Sunday, with a secondary low approaching from the south.
Improvement taking place for NYC terminals, to VFR for some terminals. There are clouds with scattered coverage between 500 ft and 1000 ft so will IFR could potentially return with any increase to broken coverage going into the start of the afternoon. To the north and east, conditions are expected to improve this afternoon.
Otherwise, improvement to MVFR this afternoon and eventually VFR for a brief time late this afternoon, then MVFR and lower develops again after around 00Z Sunday. There is considerable uncertainty in vsby and cigs forecast during the TAF period. The improvement may very well be an IFR to VFR improvement with the scattering out of low clouds for today.
SW winds pick up slightly but still below 10 kt today. Winds become light and variable after 00Z Sun, but should generally shift to the W, then NW, and finally NE by tonight. Winds increase to around 10 kt just prior to 12Z Sunday.
...NY Metro(KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...
Amendments likely for changing VIS/CIGS thru the TAF period as there is considerable uncertainty in the forecast.
The afternoon KJFK haze potential forecast is YELLOW...which implies slant range visibility 4-6SM outside of cloud.
The afternoon KLGA haze potential forecast is YELLOW...which implies slant range visibility 4-6SM outside of cloud.
The afternoon KEWR haze potential forecast is YELLOW...which implies slant range visibility 4-6SM outside of cloud.
OUTLOOK FOR 12Z MONDAY THROUGH WEDNESDAY...
Monday: Mainly VFR. W winds G20-25kt, becoming more NW at night.
Tuesday: Mainly VFR. NW winds G15-20kt.
Wednesday: Mainly VFR. N winds G15-20kt.

MARINE
SCA issued for the ocean waster for Sunday into Sunday night.
While a weak W/SW flow will prevail across the waters today, guidance shows a period of about 6-8 hours where a 5 ft southerly swell could enter the ocean waters east of Fire Island Inlet. If this occurs, it looks to be mainly across the outer waters and would be during the afternoon and early evening hours before subsiding back below 5 ft. For the time, since the seas are marginal, have held off on the issuance of a SCA. However, a strengthening easterly flow late tonight into Sunday will likely bring SCA conditions to the waters on Sunday.
Winds will then shift to W/NW Sunday night with SCA conditions possibly lingering into Monday.
5 ft waves and 25 kt gusts are possible for the ocean waters Monday night as a surface trough moves through. The 5 ft waves will mainly be for the outer ocean waters. Thereafter, sub-SCA conditions expected on all waters through Thursday.
HYDROLOGY
0.75-1" is expected late tonight into Sunday night. There are no hydrologic concerns given this is a relatively long duration event.
No hydrologic impacts are expected next week.
