Synopsis
Showers and thunderstorms will move through the region this
evening. A cold front will sweep across the region early
tomorrow followed by cooler and drier air. High pressure will
build in over the weekend and early next week allowing for fair
weather.

Near term through tonight
Warm front is beginning to sneak into southern new hampshire at
this time... With associated thunderstorm activity beginning to
weaken as it heads east into retreating cooler airmass.

Attention through this evening will turn to convective line
associated with prefrontal trough now over eastern new york.

Watching cloud trends on GOES 16 visible imagery suggests that
some partial clearing will work into far southern nh ahead of
this line... And expect this to be the focus of the severe threat
through the evening hours. While instability will be beginning
to wane... 0-6km shear will remain AOA 30kts with afternoon cams
suggesting a linear mode with bowing segments. In fact... 0-3km
shear also remains rather impressive... With 0-3km storm relative
helicity values suggesting some threat for not only damaging
winds... But mesovortex development with an isolated tornado
still possible. This matches well with what has occurred with
the line over eastern new york.

Beyond the convection... Expect ample boundary layer moisture to
result in areas of fog overnight as temperatures fall back into
the 60s... With the potential for it to be locally
dense... Particularly along the midcoast.

Short term Thursday through Thursday night
Trailing cold front will move through the region Thursday
afternoon. While moisture will be more limited than
today... There will be a rather impressive wind field aloft. At
this time... Expect a line of scattered showers to move
southeast through the region in the afternoon with the greatest
threat for thunder along the midcoast where instability will be
greatest as the front will reach here last . Will include
thunder mention... But not enhanced wording at this time given
lower confidence in occurrence. Temperatures in the mountains
remain in the 70s... But ahead of the front temperatures will
reach the mid upper 80s.

Front settles south of the region Thursday night with clearing
skies. Temperatures will fall into the 50s with valley fog
likely.

Long term Friday through Wednesday
Looks like a fairly quiet extended period. Long term starts with a
long wave trough dominating the upper level pattern over the eastern
united states, with west to southwest flow over new england. This
looks to be a fairly dry and cool pattern for us. The trough
migrates off to the east on Saturday as upper level ridging moves in
from the west. The upper level ridge will remain in place through at
least Tuesday of next week. High temperatures through this time
frame should be in the 70s, with overnight lows in the 40s and 50s.

The next chance for appreciable precipitation won't be until
Wednesday night and Thursday of next week.

Aviation 19z Wednesday through Monday
Short term through Thursday night ...

showers and embedded thunderstorms will impact the terminals
through this evening before moving east of the area overnight.

Best threat for a severe thunderstorm will be at leb con mht psm
through this evening. Otherwise... Local ifr likely in the
showers and storms before the focus turns to fog overnight with
ifr likely throughout the region and vlifr lifr more likely for
aug and rkd.

Long term... MostlyVFR with early morning valley fog.

Marine
Short term through Thursday night ...

south southwesterly winds continue through Thursday before
shifting westerly and then northwesterly behind a cold front
Thursday night. Winds will near SCA levels for a time overnight
tonight over the outer waters.

Long term... No flags expected.

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.
