SYNOPSIS. Weak low pressure passes south and east of Long Island through tonight. The low strengthens east of New England Monday into Monday night. Meanwhile another low well to the northwest will weaken into a trough as it approaches on Monday, then merge with the offshore low Monday night into Tuesday. Yet another low will pass well south and east during mid week, followed by high pressure for late week. A cold front will approach next weekend.

NEAR TERM /UNTIL 6 AM MONDAY MORNING/. A vort max rounding the base of an upper low over the Great Lakes passes to our NW overnight. This has generated some convection mainly to the north and east of the region. A trough axis in the middle levels around 850 mb is also crossing the region. The axis of convection will quickly move east of Long Island in the next few hours.

A weak surface low also passes south and east of Long Island along a stationary front. The main cold front is located across western PA and western upstate NY closer to the parent low over the Great Lakes. The front likely stays to the west overnight with the region remaining under low clouds and patchy fog. The latest forecast sounding data shows some drier air works its way south under a light northerly flow. This should help prevent any of the fog from becoming dense.

Lows tonight will be in the 40s.

SHORT TERM /6 AM MONDAY MORNING THROUGH MONDAY NIGHT/. Stacked low to our northwest weakens as it heads towards us. Limited instability will be present in the associated cold pool aloft. This will maintain clouds and trigger sct to numerous mainly afternoon showers. especially inland. With partial clearing and deeper mixing in the afternoon, temps should reach the lower 60s in NE NJ, and 50s elsewhere.

Chances for showers continue Mon night, then begin to shift westward late as associated low level convergence/lift also shifts west due to strengthening of the offshore low. Some wet snowflakes could mix in with any showers inland as temps there fall to the mid 30s, with upper 30s/lower 40s for the coast and metro area.

LONG TERM /TUESDAY THROUGH SUNDAY/. Light showers (or rain/snow showers across the interior) are possible Tuesday morning as a surface trough associated with the surface low over the western Great Lakes region continues to weaken. These showers will continue to push southwest, and mainly dry conditions return to the region by Tuesday afternoon.

A coastal storm will eject off the southeast U.S. coast and track well south and east of the region Tuesday night through Thursday. Dry conditions are therefore expected through then.

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 late Thursday night into Friday.

Thereafter, a cold front approaches for the weekend, but as of right now, due to uncertainty and light precipitation, only looks to be slight chance from Saturday afternoon through Sunday.

High temperatures will be slightly below normal Tuesday and Wednesday, then slight above normal through the rest of the long term.

AVIATION /03Z MONDAY THROUGH FRIDAY/. Weak low pressure passes south and east of Long Island through tonight. The low gradually strengthens off the New England coast on Monday as another low approaches from the NW.

IFR to LIFR conditions are likely to continue through 06z at most TAF sites. Gradual improvements are expected early Monday morning with MVFR becoming VFR through the day. Timing of improving conditions may be off by 1-2 hours. VFR prevails into Monday afternoon, but showers are possible which could bring conditions back to MVFR at times.

N-NE winds around 10-15 kt should weaken overnight with many locations becoming light and/or variable into Monday morning. The wind direction forecast for Monday afternoon and evening is of low confidence. The current forecast has winds becoming more W and then NW late around 10 kt.

OUTLOOK FOR 00Z TUESDAY THROUGH FRIDAY. Monday Night. MVFR likely with IFR possible. Chance of showers. Tuesday. Chance of MVFR in showers. Wednesday-Friday. VFR. NW G15-20kt Thursday and Friday.

MARINE. Visibilities have improved on the waters and do not anticipate dense fog redeveloping overnight. Winds and seas have also subsided on Long Island Sound. As the pressure gradient continues relaxing tonight, seas will diminish, though the ocean waters will remain above 5 ft into Monday night.

Some gusts up to 25 kt are possible late Mon night into Tue morning E of Moriches Inlet as low pressure off to the east strengthens somewhat. Thereafter, hazardous ocean seas there should linger through the day on Tue, possibly into Wed morning.

HYDROLOGY. No hydrologic impacts expected.

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

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
