Synopsis
High pressure slowly builds in across the area into Wednesday
and shifts into the western atlantic Wednesday night. Low
pressure slowly moves through the area Thursday into Friday
night, before departing to the northeast on Saturday. High
pressure then builds to the south while weak low pressure moves
across the great lakes and slowly approaches the area into early
next week.

Near term until 6 am Wednesday morning
High pressure continues to build into the region. With the
pressure gradient continuing to relax, expect winds to diminish
overnight. Conditions will remain mostly clear allowing for near
ideal conditions for radiational cooling. Lows tonight will
fall into teens and 20s. Some downward adjustments were made
with the evening update. Much depends on wind forecast.

Short term 6 am Wednesday morning through Wednesday night
The high pressure axis over the region slowly drifts east during
the day Wednesday and Wednesday night. Sky conditions will
generally be mostly sunny, with just some over-the-ridge cirrus
anticipated. Highs on Wednesday will reach the lower and middle
40s, with lows Wednesday night falling into the 20s and 30s.

Long term Thursday through Tuesday
Main focus on the extended will be potential flooding rainfall set
to occur Thursday night into Saturday.

An upper trough moving into the pacific northwest is expected to
phase with an upper low over the southwest, significantly
strengthening meridional flow into the late week. As a result,
strong southerly flow will allow not only an unseasonably warm air
mass, but also an influx of gulf moisture that will lead to pwat
potentially near record values by Friday. With a warm front moving
through Thursday night, the area will be in the warm sector by
Friday, with at least weak instability aloft increasing the
potential for thunderstorms that may locally enhance rainfall rates
as well. Ensemble and deterministic forecasts have trended higher
with potential precipitation amounts, generally ranging from 1-3
inches for the duration of the event.

There remains uncertainty as to how much wind can mix to the
surface, with most deterministic models continuing to show low level
winds peaking around 60-70kt at 925 mb by Friday. As mentioned by
the previous forecaster, a strong inversion just above the surface
will likely limit gust potential on land with exception of any heavy
rain which could bring down the higher gusts of perhaps 40kt.

The region remains in the warm sector Friday night with showers
becoming more occasional in frequency and fog will be possible as
well with the moisture laden grounds and decreasing winds. Min
temperatures forecast Friday night are only in the low to upper 40s.

The system finally departs on Saturday, though with a final
vorticity maximum and attendant surface trough moving through
leading to the potential for a brief line of showers Saturday
morning. Thereafter, gusty northwest flow dominates, with a cooler
and drier air mass into early next week. Temperatures return to
closer to normal values overall this weekend.

Aviation 00z Wednesday through Sunday
High pressure builds in from the west, while strong low pressure
tracks northeast across the canadian maritimes. This will
result in a gradually diminishing NW flow andVFR conditions.

Frq gusts have subsided, however an ocnl gust up to 20kt
through 02-03z is possible. Winds become SW 5-10kt on Wed as
the high passes to the S and moves offshore.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
