SYNOPSIS. High pressure centered over eastern Canada will continue to build across the Northeast tonight and settle off the New England coast on Monday. The high will gradually give way to a slow moving cold front during the middle of the week, which passes through the area late Thursday into Friday. High pressure may briefly return Saturday ahead of another cold front for Sunday.

NEAR TERM /UNTIL 6 AM MONDAY MORNING/. Forecast was updated with a decrease of min temperatures of a few degrees across the region. Min temperatures were lowered more across the interior and rural sections of the region. Min temperatures forecast range from the mid 40s to lower 60s.

High pressure continues to build in at the surface and a high amplitude ridge builds in aloft. A northerly flow and dry air mixing down to the surface has allowed dewpoints to drop into the upper 40s and lower 50s for much of the area making for a comfortable feel.

The blend of MET/MAV MOS and their relatively cooler solutions for tonight's lows were further lowered slightly under this regime. Great radiational cooling conditions under clear skies, light winds and a dry airmass will allow the interior and the LI Pine Barrens to drop to the mid 40s. The NYC metro area will drop to the lower 60s and the rest of the area into the 50s, which is around normal for mid September.

SHORT TERM /6 AM MONDAY MORNING THROUGH TUESDAY/. High pressure shifts off of the New England coast Monday morning and in return we see a more southeasterly flow. This onshore flow will allow the lower levels to gradually moisten under subsidence aloft.

Another dry and sunny day is expected, with highs in the 70s around the area. Lows will be warmer than Sunday night due to an onshore flow. There is a chance that fog and/or stratus develop early Tuesday morning as the lower levels reach saturation. Have introduce patchy fog late Monday night into early Tuesday morning for most of the area. Confidence is low in coverage, especially across Long Island where winds may be too high.

LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/. The long term will start out with a large and anomalous ridge over the eastern seaboard and western Atlantic. Large surface high pressure will be centered near the Canadian Maritimes, but dominate the surface pattern across the northeast. The GFS and NAM soundings indicate a strong subsidence inversion on Tuesday, with moisture becoming trapped below it. Scattered to broken stratus or stratocumulus may result, especially across the western half of the area. The closer proximity to the surface high further east may limit the degree of cloud cover there on Tuesday. Highs will be close to seasonable levels in the lower and middle 70s.

The upper ridge gradually shifts offshore on Wednesday as an amplifying upper trough digs across the Great Lakes down into the southeast. The models are starting to come into better agreement that trough will become a cut-off upper low somewhere near the Ohio Valley or Great Lakes on Wednesday night. A cold front associated with the trough will gradually approach. However, the modeling continues to slow the system, down and this is largely due to the upper level low. The offshore ridging has also trended stronger and is likely playing a key role in slowing down the progress of the trough and front. With the trough cutting off, the associated surface low is progged to occlude as the system slowly lifts north Thursday into Friday. The global models and ensembles are still in disagreement with how quickly this occurs. In fact, there are still a respectable number of ensemble members that are showing a faster evolution with the cold front moving across the area sometime on Thursday or Thursday night. However, the latest deterministic runs have slowed down with the front moving through late Thursday night into Friday. Given the uncertainty with the upper low and offshore ridge, feel any of these scenarios are still plausible. The biggest change to the forecast was to lower PoPs on Wednesday and Wednesday night, which are below the NBM. Have indicated a gradual increase in PoPs Thursday into Thursday night. Due to a potential slower timing, have bumped PoPs up a bit on Friday.

As for sensible weather, a few warm advection showers cannot be ruled out on Wednesday/Wednesday night due to persistent onshore flow. However, the main axis of deep moisture, lift, and showers should reside west of the area until sometime on Thursday or Thursday night. Since the low pressure is likely to occlude, the overall large scale forcing may end up waning as the front moves across our area. This could play a role in how much rainfall would occur. Overall, there remains a risk of a widespread rainfall, potentially seeing amounts around one inch to one half inch on average. Forecast confidence remains low on specific rainfall amounts, rainfall rates, and potential impacts, if any.

The front may finally push offshore on Saturday as the upper trough to the west potentially amplifies further with a secondary cold front approaching for the second half of the weekend. Have currently gone with a mostly dry forecast for the weekend with the main axis of moisture offshore. If the trough were to be more amplified, the secondary front could bring some showers by next Sunday.

While somewhat cooler conditions are possible this weekend, temperatures overall should average close to normal.

AVIATION /04Z MONDAY THROUGH FRIDAY/. High pressure will continue to build across the region tonight through Monday morning and then will slowly slide east into coastal New England Monday afternoon into Monday night.

VFR conditions are expected through the TAF period. Winds will be near 5 kts or less and variable in direction but generally E-NE for NYC terminals tonight. Winds for all terminals will become more SE and increase to near 7-10 kt Monday.

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

Timing of SE wind shift may be off by 1-2 hours Monday.

OUTLOOK FOR 00Z TUESDAY THROUGH THURSDAY. Mon PM. Mainly VFR. Possible MVFR/IFR late with patchy fog and stratus. Tue. Chance of MVFR AM in patchy fog and stratus. Otherwise, VFR. Wed. MVFR or lower possible in showers mainly PM hours. SE winds 10-15 kt with gusts up to 20 kt. Thu. MVFR or lower possible in showers. Slight chance of thunderstorms afternoon into evening. SE winds 10-15 kt gusts 20-25 kt. SE-S winds near 10 kt with gusts more in the 15-20 kt range at night. Fri. MVFR or lower possible in showers. SW-W winds near 10 kt with gusts 15-20 kt.

Detailed information, including hourly TAF wind component forecasts, can be found at: https:/www.weather.gov/zny/n90

MARINE. Winds and seas will remain below SCA through Monday.

High pressure continues to slowly moves away from the waters Tuesday into Wednesday. SE flow between the high and a slow moving cold front will increase late Wednesday into Thursday. This may lead to ocean seas building to SCA levels on the ocean as well winds approaching 25 kt on the ocean. SCA conditions could continue on Friday, especially if the cold front moves through slower.

HYDROLOGY. No hydrologic impacts are expected through Wednesday.

A significant rainfall is possible with a slow moving cold front Thursday into potentially Friday. However, specific rainfall amounts and any impacts are too uncertain at this time.

TIDES/COASTAL FLOODING. There is a moderate rip current risk through Tuesday due to persistent easterly swells.

Water levels are expected to remain just below minor coastal flooding benchmarks across the south shore back bays of Nassau county with this evening and Monday evening high tides.
