Synopsis for the long island and connecticut coastal waters - Low pressure remains well east of the long island through through Friday night. On Saturday, the low lingers offshore as high pressure noses in from the northeast. High pressure continues to build in on Sunday and remains in control through Tuesday. A frontal system approaches from the west mid to late week.

SYNOPSIS
Low pressure remains south and east of the Long Island through through Friday night. Over the weekend, the low begins track slowly south and east and father out into the western Atlantic.
At the same time, high pressure noses in from the northeast and remains in control through Tuesday. A frontal system approaches from the west mid to late week.
NEAR TERM /UNTIL 6 AM THIS MORNING/
No changes with this update as the forecast remains on track.
An upper level trough remains over the region tonight, with a surface low remaining east of Long Island. This low remain nearly stationary, with little movement, locking the region into a persistent northeast to northerly flow.
While the forecast models have been trying to produce precipitation over area, there has been decent mid level drying, which I expect to continue, so will continue to trend the forecast in that direction and follow more of a persistence based forecast.
Expect dry conditions, except for some minimal / slight chance POPs over the eastern portions of New London CT and portions of the Twin Forks of Long Island. Can not rule out a few rain showers in bands wrapping around the spinning low, but this activity has had difficulty getting further west based on latest sat / rad trends.
Expect lows in the upper 50s to middle 60s.
SHORT TERM /6 AM THIS MORNING THROUGH 6 PM SATURDAY/
Very little change in the overall weather pattern through the short term period with the upper trough remaining over the region and a surface low remaining east of Long Island. One thing to note however, is late in the period, as the surface low and upper trough slightly shift eastward, this will allow ridging aloft to start nosing in from the north.
Similar to the short term period, models continue to trend drier this period. So will continue with a drier forecast with keeping some some low POPS mainly across eastern sections of CT and Long Island. It appears that the highest chances for any rain will remain offshore.
The region will remain under a persistent N-NE flow.
Temperatures on Friday will be in the 70s and lower 80s. Lows Friday night fall into the 50s and 60s.
LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/
**Key Points**
*Improving conditions Saturday into Sunday as high pressure builds into the region.
*Downward temperature trend to slightly below normal temperatures expected by early next week.
*A frontal system mid to late will bring with it additional chances for showers.
The offshore low will still be spinning in place to start Saturday and then slowly start to drift eastward. At the same time, high pressure to out northeast slowly noses into our area. With the surface ridging and some dry air moving into the area, much of the area will remain dry on Saturday. The best chance of any showers will be eastern Long Island and eastern CT. Given the tight pressure gradient, a gusty northeast flow is expected. Gusts 25 to 35 mph for eastern LI and eastern CT and mainly 20 to 25 elsewhere. Northeast winds will begin to relax by Sunday afternoon as the low departs and the pressure gradient weakens.
Thereafter, upper ridging begins to build in with surface high pressure nosing in from the north. Dry conditions are generally expected Sunday through Tuesday. A slightly cooler airmass advects into the area for Monday and Tuesday under easterly flow and highs in the upper 60s and low 70s.
The airmass begins to moderate somewhat on Wednesday, though still below normal in the low 70s, with increasing cloud cover and a chance of showers from an approaching frontal system to the west.
Guidance varies on timing, with some starting showers as early as Tuesday night, while others keep the rain away until Thursday morning. Overall, not expecting this to be a very impactful system, rather just another chance for passing showers as the low passes north with a front dragging through our area.
The NBM was primarily used for the forecast. Some adjustments were made to low temps Sunday night across the interior as clear skies and lightening winds may allow for some better cooling.
AVIATION /06Z FRIDAY THROUGH TUESDAY/
Low pressure remains offshore, east of Long Island through the TAF period.
VFR, except for eastern terminals at times, with KGON going MVFR overnight and into this morning, and perhaps into early the afternoon. KISP and KBDR may briefly experience MVFR ceilings for early Friday morning. KGON will have another period of MVFR Friday night.
Winds will be mainly NE and around 7-10 kt for most terminals overnight, with a few inland terminals closer to 5 kt. KGON however is expected to have gusts up to 20 kt overnight. NE winds pick up again for all terminals with gusts resuming by 14 to 15z Friday for most terminals with sustained winds 10-15 kt, and g17-25 kt.
...NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...
Confidence remains high with wind direction into Friday. Amendments may be needed for KEWR and KTEB for Friday where wind gusts may be more occasional.
OUTLOOK FOR 06Z SATURDAY THROUGH TUESDAY...
Late Friday night: Mainly VFR, pockets of MVFR possible east.
Saturday: VFR. MVFR east of the NYC terminals in possible showers, but low chance of occurring. NE gusts around 15-25 kt possible, highest gusts east.
Sunday: VFR. NE gusts 15-25 kt possible, highest gusts east.
Monday...VFR.
Tuesday..Mainly VFR, with pockets of MVFR possible.

MARINE
Small craft advisories remain up on the ocean waters through Friday night and will likely need to be expanded in the weekend as a persistent N-NE flow keep seas above 5 ft. SCA winds will be a little more challenging to reach, however its likely we see some gusts to 25 kt through parts of this time frame. For the non-ocean waters, lesser confidence of reaching SCA conditions and thus have cancelled any remaining non-ocean SCAs. Confidence of SCA conditions on the non-ocean waters is just not high enough at this time for any headlines.
6-9 ft waves and 25-30kt gusts will continue on the ocean waters this weekend and at the start of next week. While the LI Sound and Bays may not see 5+ ft waves, gusts near 25 kt will be possible until Sunday night.
HYDROLOGY
There are no hydrologic issues through the middle of next week.
TIDES/COASTAL FLOODING
Multiple rounds of coastal flooding are expected through this weekend with low pressure to the southeast slowly drifting farther out into the western Atlantic. This will result in a building easterly swell that will help to pile water into the area in conjunction with high astronomical tides. Northerly winds will also develop more of an easterly component the second half of the weekend which will contribute to the wind forcing component of the surge.
Surge forecast is generally 1 1/2 to 2 1/2 ft with the highest of the tides being during the morning into afternoon high tide cycles. This results in locations adjacent to western LI Sound and the south shore bays of western LI getting to around moderate benchmarks Friday with widespread minor elsewhere.
Thus, there are coastal flood warnings for those moderate locations and advisories elsewhere. There is also the potential for another round of moderate coastal flooding Saturday morning for southern Nassau, southern Queens, and SW Suffolk, where a coastal flood watch in in effect. Most other locations will likely see minor flooding continuing. The threat gradually lessens Sunday into Monday with any moderate flooding expected to be more localized. Astronomical levels will also be on the downswing.
In addition, due to the building easterly swell there is a high rip current risk through Saturday, which will likely need to be extended into Sunday at some point.
