SYNOPSIS. Offshore high pressure continues to move into the northern Atlantic tonight as weakening low pressure and a warm front slowly approach through Tuesday. The warm front remains to the south of the region Tuesday night and Wednesday as another low begins to develop over the Ohio Valley. Deepening low pressure moves across New England Wednesday Night into Thursday. The low will gradually weaken as it remains nearly stationary across Southeastern Canada Friday and Saturday. High pressure builds to East Coast Sunday into Monday.

NEAR TERM /UNTIL 6 AM THIS MORNING/. Temperatures have been slow to fall so far tonight with plenty of cloud cover over the region. Adjusted the hourly temperatures over the next several hours, otherwise the forecast remains on track.

Otherwise, current trends continue to delay phasing of the northern stream trough with the southern stream shortwave moving out from the southwestern mountain states. Also, the eastern ridge remains amplified across the western Atlantic. Surface ridging across southeastern Canada will suppress the warm front to the south. Much of the night will be dry with precipitation chances increasing from the south toward Tuesday morning.

SHORT TERM /6 AM THIS MORNING THROUGH 6 PM WEDNESDAY/. The southern stream low becomes absorbed into the northern trough Tuesday and weakens through Tuesday night. With a weak pressure gradient and high pressure to the north, the warm front will remain to the south through Tuesday night. There will be some frontal forcing and isentropic lift, so chances of precipitation increase through Tuesday, south to north. This forcing moves north and weakens Tuesday night with the warm front somewhere south of Long Island. Low level moisture will remain in place, and winds will be light. So will have periods of light rain and drizzle Tuesday night, with areas of fog. With the warm front to the south have leaned toward the cooler guidance.

LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/. An organizing long wave trough over the Central States will amplify heights across the eastern seaboard on Wednesday. Low pressure will be developing across the Ohio Valley and Middle Atlantic ahead of the trough. Over the northeast, lingering surface ridging and ridging aloft will make it very difficult for any substantial precipitation. A warm front to the south and some weak overrunning may promote some light rain or drizzle. At the present time, do not anticipate this to be widespread. Some areas of fog are also possible. Have lowered high temperatures for Wednesday into the middle and upper 40s.

The main bands of showers with the deepening low pressure will move across Wednesday night. There is still some marginal elevated instability to include mention of thunder. The rain bands should move across quickly and do not anticipate any flooding but there could be some brief moderate to locally heavy downpours. The rain should taper off quickly from west to east early Thursday morning. The warm front may never fully move across the region. It is becoming more likely that a triple point low will move across within the larger deepening low pressure system.

Any lingering showers quickly end Thursday morning with dry conditions as the low lifts across New England. The longwave trough will become a closed upper low over Southeast Canada and northern New England. There is good agreement among the Deterministic and Ensemble models that the upper low will linger through the first half of the weekend and then gradually move offshore Sunday into early next week. Have gone with a dry forecast for late Thursday through the weekend with a persistent NW flow around the low. Specific pieces of energy around the flow could develop some snow showers or flurries at times, but it is too difficult to determine exactly when and where. Gusty W winds are likely on Thursday behind the low, 25-35 mph. Breezy conditions should continue into Saturday as the region remains sandwiched between the low to the north and high pressure to the west. High pressure builds to the east coast Sunday into Monday.

Temperatures start out above normal Wednesday and Thursday and then run below normal Friday into the weekend.

AVIATION /06Z TUESDAY THROUGH SATURDAY/. Weak high pressure over the Northeast moves away overnight and gives way to a warm front moving northward into the Mid Atlantic states on Tuesday. A wave of low pressure along the front will pass well south and east of the area Tuesday afternoon.

VFR into Tuesday morning, although some guidance has suggested sct to bkn clouds at around 2 hundred ft towards 9-10z for city and coastal terminals. Confidence is low at this time that this would actually materialize, thus this will have to be monitored. With that said, it is mainly a VFR forecast through much of Tuesday morning, with the likelihood of MVFR conditions increasing through Tuesday afternoon in light rain. Afterwards, into Tuesday evening the chances for IFR conditions will increase, although confidence is low in the timing of IFR conditions into Tuesday evening.

The winds have gone light to calm for the overnight. The winds will then back to the E/NE around 5 kt late Tuesday morning into Tuesday afternoon.

OUTLOOK FOR 06Z WEDNESDAY THROUGH SATURDAY. Tuesday Night. IFR to MVFR with light rain. Wednesday. MVFR/IFR in light rain during the day, then a chance of showers and isolated thunderstorms in the evening. E-SE gusts 15-20 kt at night, mainly along the coast. Thursday. Improving to VFR. W gusts 25-30 kt. Friday. Mainly VFR. Chance Flurries at KSWF. W gusts around 25 kt. Saturday. Mainly VFR. W gusts around 20 kt.

MARINE. A light flow is expected across the forecast waters tonight into Tuesday evening. Late Tuesday night an easterly flow will begin to strengthen. Winds and gusts are expected to remain below SCA levels across all the waters through Tuesday night. Ocean seas will build Tuesday night and may reach minimal SCA levels across the eastern ocean waters toward Wednesday morning.

SCA conditions will be likely on the ocean on Wednesday, mainly in elevated seas. E-SE winds increase late in the day and at night as deepening low pressure approaches. SCA conditions are likely on all waters by Thursday morning. These conditions will continue through the day as the low moves to the north and a W flow increases. Gales are also likely on the ocean and will mention in the HWO. Winds will gradually diminish below SCA levels on the sheltered waters Thursday night, but should continue on the ocean into Friday. Elevated ocean seas will also continue. There is chance for SCA conditions to continue on the ocean on Saturday as winds may remain near 25 kt.

HYDROLOGY. Light rain moves into the southern portion of the region late tonight, with light rain across the region Tuesday. Periods of light rain and drizzle will be possible Tuesday night. Rainfall from late tonight through Tuesday night is expected to be a tenth to two tenths of an inch.

Rainfall of 1/2 to 3/4 inch is possible Wednesday night as low pressure moves across. No hydrologic issues are anticipated at this time.

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. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
