SYNOPSIS. A series of upper level disturbances will move across into tonight. A cold front will also pass through this evening. High pressure will then gradually build in through Thursday night before moving offshore on Friday. There is then much uncertainty with a potential coastal low this weekend.

NEAR TERM /UNTIL 6 PM THIS EVENING/. Mid level disturbances rotating around an upper low in the Canadian Maritimes, and mainly low level cyclonic flow with moisture trapped beneath an H8 inversion, should maintain cloud cover most of today. Skies were overcast at most spots, with IR satellite showing some breaks developing across NJ and eastern CT. As a weak mid level shortwave ridge passes across this morning between disturbances, it is possible that clouds could scatter out briefly late this morning or early this afternoon, the cloud up again mid to late afternoon as the next mid level shortwave trough approaches from the NW and a sfc cold front advances from the N.

High temps were slightly higher than a MOS blend, upper 30s/near 40 inland and lower 40s metro/coastal sections.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM WEDNESDAY/. Sfc high pressure will build southward into the region tonight, with gradual clearing mainly after midnight, then a mostly sunny day on Wed. Low temps tonight should be in the 20s, perhaps some upper teens in some of the interior valleys, then high temps on Wed should be fairly close to those of today, with upper 30s/lower 40s expected.

LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/. At the onset of the period, an upper trough will be pulling away from the Canadian maritimes, while ridging builds across the east as a trough begin to take shape over the mid section of the country. The latter of which poses a good deal of uncertainty for the upcoming weekend.

Before then though, high pressure builds across the northeast through Thursday night, before retreating offshore on Friday. Temperatures will be a shade below normal Thursday and then moderate into the upcoming weekend with highs around 40 and lows in the 20s inland to the lower 30s at the coast.

For days now, the global guidance has been bouncing around with the intensity and track of a coastal low that develops off the eastern seaboard Friday night into Saturday. Multiple streams within the southern branch itself and complex interaction between embedded shortwaves are producing a variety of solutions. Further compacting this interaction, is additional Pac shortwave energy moving into western Canada today. Overall though, the placement of the upper trough over the east this weekend is not too dissimilar amongst the guidance. The operational GFS is the deepest of the operational members and tracks the low just inside the 40N/70W benchmark on Saturday. The GEFS mean is farther offshore like GGEM and ECMWF, both of which also have a weaker wave passing to the south and east Friday night before the main low. For the time, have a low chance for rain or snow along the coast Friday night and again with the main low Saturday into Saturday night.

Another important fact here is the airmass is only marginally cold and the exact track will be critical in precipitation type. Even the GFS track, which is often favorable for snow at the coast, is supporting mainly rain at the onset with a transition to snow at the end.

Bottom line, it is much too early to be specific with any details at this time. Perhaps, as some of the Pac energy moves onshore today, we will begin to get more consensus in the guidance.

AVIATION /09Z TUESDAY THROUGH SATURDAY/. Low pressure over the Canadian Maritimes moves slowly east as a large area of high pressure gradually builds in from the west. This will keep the area under a NW flow.

VFR. BKN-OVC clouds 4-6 kft through the day today. There may be a brief period this morning where skies scatter for a time. If this occurs, it is expected to be short lived. SCT-BKN clouds linger through the evening 4-6 kft.

NW winds prevail 10 kt or less early, then increase slightly after 14-15Z, and a few gusts 15-20 kt are possible during the afternoon. Gusts become less frequent or end altogether by evening.

OUTLOOK FOR 06Z WEDNESDAY THROUGH SATURDAY. Late tonight through Friday night. VFR. Saturday. MVFR or lower possible in rain or snow.

MARINE. Conds on the ocean waters should be just below SCA levels into this evening, with winds gusting just over 20 kt and seas 4 ft. Expect more tranquil conditions late tonight into Friday as high pressure builds in.

The next chance of SCA conditions should be over the weekend, with the potential of a coastal low impacting the waters. Uncertainty in track and intensity remains high.

HYDROLOGY. No hydrologic impacts are anticipated through Friday.

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

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
