SYNOPSIS. A warm front will continue to approach from the south overnight, stalling just south of Long Island Sunday morning. Weak low pressure and a trailing cold front will then move across the area Sunday night. Low pressure over the western Great Lakes and New England weakens Monday into Tuesday. Another low will pass well south and east during the middle of the week, followed by high pressure to close out the week.

NEAR TERM /UNTIL 6 AM SUNDAY MORNING/. Area of convection across southeast PA may influence how widespread rain is for some of the night. PoPs may have to be lowered a bit after this batch of rain currently over the area moves through. Otherwise, the forecast is on track.

A closed upper low will track toward the Great Lakes tonight, while a high amplitude ridge will work off the eastern seaboard. This will place the area under prolonged period of large scale warm advection. Occasional rain will continue through the night and at times could become moderate. Toward daybreak, as mid level dry air works in aloft, the rain may transition to light rain and drizzle. While all the dynamics are displaced well west of the area, there is decent thermal forcing through the overnight as a 35-40 kt southerly LLJ works across the area.

East winds will strengthen through tonight with the potential for gusts up to 25 mph, mainly near the coast.

Lows will remain well above normal, generally in the mid 40s.

SHORT TERM /6 AM SUNDAY MORNING THROUGH SUNDAY NIGHT/. Warm front stalls just south of Long Island on Sunday with occasional rain and drizzle through most of the day. Gusty east winds along the coast in the morning will diminish through the afternoon. A frontal wave will then approach from the west in the afternoon. While there is marginal elevated instability in the afternoon with height falls aloft, there is no surface based instability and the forcing is week. There could be a brief shower in the evening hours as a weak cold front passes through the area, otherwise any light rain and/or drizzle will taper off during the evening hours.

Highs Sunday will be around 50, with lows again the 40s.

LONG TERM /MONDAY THROUGH SATURDAY/. Stacked low pressure over the western Great Lakes region will track southeast into northern and central New York Monday morning into Tuesday morning, weakening as it does so. Associated cold pool aloft will lead to some instability, while at the surface, an inverted trough will be in place. This will allow enough instability and lift for some light showers through the period, though exactly where they will be is still uncertain. However, highest chances would be for areas closest to the stacked low, which would be for more northern portions of the forecast area. Best chances for showers would be Monday afternoon into the first part of Monday night.

Mainly dry conditions are then forecast Tuesday afternoon through the rest of the week. However, there will be chances for passing showers as a coastal low passes well south and east late Tuesday night into Wednesday, mainly across western and southern sections.

As the storm intensifies and expands well east of the region Thursday night, the western edge of the precipitation field will move westward toward our area. Some vorticity maxima may move through aloft, as well as spokes of surface troughs rotating around the low which will aid in the possibility for showers, but right now, looks to only be a slight chance for extreme eastern areas.

Thereafter, dry conditions are forecast through the end of the week with high pressure building in.

Other than some above normal temperatures for Monday, seasonable temperatures are expected through the week.

AVIATION /00Z SUNDAY THROUGH THURSDAY/. A warm front will approach from the south through tonight. The front becomes stationary south of Long Island on Sunday.

Conditions will continue lowering to MVFR and then IFR through 03z in rain. Timing of lower flight categories this evening may be off by 1-2 hours. The rain should become intermittent overnight and could be in the form of drizzle. Conditions will likely lower to LIFR early Sunday morning in ceilings. Visibilities lower to IFR, but may also become LIFR briefly. IFR, possibly LIFR at times, is expected through Sunday in light rain and drizzle. Some improvement is possible late in the day.

NE winds around 10 kt this evening. NE-E winds become 10-15 kt overnight especially near the coast. Gusts up to 20 kt are also expected near the coast into Sunday morning. NE-E winds around 10-15 kt Sunday morning and afternoon gradually weaken late in the day.

OUTLOOK FOR 00Z MONDAY THROUGH THURSDAY. Sunday Night. IFR or LIFR early, then improving to VFR late. Monday. Mainly VFR. A few showers possible in the afternoon and at night. Tuesday-Wednesday. Mainly VFR. Slight chance of showers Tuesday morning and then again on Wednesday. Thursday. VFR.

MARINE. East winds will continue to gradually strengthen through the evening with SCA conditions developing across all waters with gusts 25 to 30 kt. Seas will build to 5 to 8 ft on the ocean and 2 to 4 ft on the sound, possibly as high as 5 ft in spots. Winds will diminish from west to east on Sunday as the pressure gradient relaxes. However, SCA seas are expected to linger on the ocean waters through Sunday night.

Waves on the ocean waters will remain around 5 ft Monday, diminishing slowly through the day, falling below 5 ft early Monday night. Thereafter, light winds will lend to sub SCA waves.

A coastal storm will pass well south and east of the region in the middle of the week, however it will pass far enough south to allow winds to remain below 25 kt through the forecast period.

HYDROLOGY. Rainfall amounts through Sunday evening will range from 0.50 to 0.75 inches. This will be falling over a long period of time, so no hydrologic impacts are expected with this system. No hydrologic impacts are anticipated through the coming week.

EQUIPMENT. NYC NOAA Weather Radio Station KWO35 (162.55 MHz) is undergoing its final stages of testing, and is operating at full 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.
