Synopsis
Low pressure passes through late tonight into Friday morning,
then intensifies as it moves slowly northeast toward the
canadian maritimes later Friday into Saturday. High pressure
builds to the south and west of the area through Sunday night,
followed by a cold frontal passage Monday. High pressure then
builds in through mid week.

Near term until 6 am Friday morning
Surface low strengthens as it heads north towards us. Its center
moves in overhead towards daybreak. Ahead of it, lift from a LLJ and
good moisture convergence and perhaps a little instability aloft
combine for moderate rainfall. The rain could be heavy at times
until these factors shift out of the area late at night. Can't
completely rule out a rumble of thunder, but will leave it out
the mention of it due its low probability and coverage. It
still appears that rainfall rates would fall short of flash
flood guidance, but minor urban and small stream flooding remain
possible.

Temperatures will drop off slightly this evening, but will remain in
the 40s for the most part.

Short term 6 am Friday morning through Friday night
Friday begins with the surface low right over the forecast area
which deepens and shifts NE more rapidly along with a closed low
aloft. Another closed low and shortwave then approach us from the
great lakes. Lingering rain directly associated with the low shifts
north out of the area during the morning, then the cold pool aloft
and approaching lift maintain a threat of showers mainly north and
west of the city. Wnw winds begin to increase in response to the
deepening surface low to the NE with gusts up to around 35 mph
possible in the afternoon. Highs range mostly in the mid and upper
40s.

The shortwave upper low shift through during the evening, bringing a
chance of pcpn to the entire area, which could be a mix of rain and
snow north of the city. Looks like only areas north and east of the
city would still have a chance of additional pcpn after midnight. It
remains breezy through the night with a gusty westerly flow
increasing, but likely remaining below advisory criteria. A few
gusts may still approach 45 mph.

Long term Saturday through Thursday
A strong upper low lifts northward across the canadian maritimes
on Saturday with shortwave ridging building in on the backside
Saturday night through Sunday. This will be short-lived though
as a polar vortex over hudson bay drops into eastern canada.

The latter of which will send a strong cold front through the
region on Monday.

Gusty wnw winds will continue on Saturday due to a strong
pressure gradient between the departing low over the canadian
maritimes and high pressure building across the ohio and
tennessee valleys. Gusts up to 40 kt will be possible in the
morning, but then begin to gradually subside through Saturday
night. High pressure builds to the south and west of the area
Sunday, then gives way to a strong cold front on Monday. There
are subtle timing differences, but consensus supports a late
morning into early afternoon passage. There is a chance of a
light post-frontal rain event, mainly in the afternoon, ending
along the coast by early evening. Upper trough at this time
looks to be too progressive for any phasing with a southern
branch shortwave trough that passes to the south. This will be
watched in subsequent days.

More importantly, an anomalously cold airmass moves into the
area Monday night into Tuesday. After highs in the 50s Sunday
and Monday, readings will struggle to get into the lower 40s on
Tuesday. Airmass will then gradually moderate through Thursday,
but remain dry.

Aviation 20z Thursday through Tuesday
Low pressure approaches from the south this eve, passes overhead
late tonight and away from the region fri.

Easterly winds increase thru 0-3z. Winds then decrease as the low
approaches, then tracks over the area. A high amount of variability
can be expected as the low passes. Winds become NW then wnw on fri
as the low exits. Speeds increase with gusts to around 30kt likely.

Low level wind shear is expected this evening for most coastal
terminals as a 40 to 50 kt jet moves into the area at 1-2 kft.

Rain, mainly light, will continue this aftn from kjfk-kswf and
points w. A heavier rain will overspread the entire region from the
s this eve. The rain will lighten late tngt as the low passes over
the area. A period of lifr is possible 8-13z INVOF the low.

Improvement toVFR aft 15z as the low pulls away.

Sct shra shsn possible aft 18z which could produce MVFR or lower.

Coverage and timing is too uncertain to include pcpn in the tafs
attm.

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.
