1006 am edt Sun jul 22 2018
Low pressure will move to our northwest today and this will
allow for showers, possibly heavy at times today. There could be
a few rumbles of thunder. A tropical air mass will remain in
place through at least mid week with scattered tropical showers
and thunderstorms each day, mainly across the far interior. A
cold front crosses the region Thursday or Friday and moves
Near term until 6 pm this evening
10 am update: a narrow tropical band of heavy showers currently
extends across southern nh moving north. Other showers also
developing offshore and further north ahead of this main band of
showers. All of the showers moving north. Increased QPF amounts
and pops in a few areas as well as massaged temps dewpts a few
degs all based on latest radar and mesonet data. The tropical
air mass to our south moving north over the cold waters later
today should generate widespread fog along the coastal plain so
made some adjustments in those areas for the next 24 hours.
605 am update... Have delayed the arrival of rainfall by a few
hours this morning as narrow atmospheric river to our south has
slowed. It will move northward this morning with rain
overspreading the region in a few hours. Heaviest rain continues
to be expected over southern nh with lesser amounts further
north and east.
a deep layer meridional flow will set up today with a closed
low well to the west of the region. This will allow for a high
pwat air mass to flow northward into our region today. Rain
associated with the short wave trough embedded in the deep layer
southeasterly flow is making northward progress across ct and ma
as of 06z. The northward trend will continue allowing widespread
showers to move from south to north across our CWA this morning.
Some may be heavy but thunder chances look low this morning at
this time. Best chance for a few rumbles will be across southern
The forcing for ascent responsible for the steadier
precipitation will move off to the northeast this afternoon.
This means the precipitation will become more showery and less
widespread. We have lowered pops to chance and low likely across
much of nh and southern me for this afternoon. The best chance
for thunderstorms will be across southern nh INVOF warm front
where a few breaks of Sun will be possible which should allow
weak SBCAPE to form. Low level hodographs in this area will be
somewhat large... Supporting 0-1km SRH of 100-150 m2 s2. If
enough instability does develop to support a couple of
persistent updrafts, a few rotating storms will be possible with
a low but non-zero chance of a brief tornado or isolated strong
wind gusts later this afternoon.
Short term 6 pm this evening through 6 pm Monday
A warm and muggy night is expected tonight with this air mass
remaining in place right through Monday. Deep layer meridional
flow will continue overnight allowing for occasional bursts of
showers and perhaps a few thunderstorms. Areas of dense fog will|
be possible. The same story GOES for Monday, but with deep layer
ridge to our east pushing westward, much of the shower and
thunderstorm activity may be across the far interior allowing
the coast to have a drier day.
Long term Monday night through Saturday
The deterministic model solutions remain in decent agreement on
the long wave pattern through next weekend... Which lends increased
confidence for latter portions of the forecast. We begin the
period with a western atlantic ridge and an upper trough over the
eastern third of the conus. The ridge will briefly build westward
into northern new england for Tuesday and Wednesday which should
help inhibit convective potential... Especially over coastal
sections. Meanwhile... The upper ridge initially over the western
two thirds of the CONUS will weaken with shortwave energy eventually
carving out a broad upper trough stretching from the northern
plains to the northeast CONUS by the end of the forecast period.
The period begins with an offshore high transporting warm and
increasingly humid air northward into the region. Daytime heating
and a series of passing weak shortwave impulses will produce
scattered convection accompanied by tropical downpours at times.
There'll be little change in sensible weather until a series of
cold fronts cross the area Thursday through Saturday accompanied
by more organized and widespread convection. By Sunday we should
finally see a brief respite from the heat and humidity.
Aviation 14z Sunday through Thursday
Short term... Clouds will continue to lower today with ifr for
most terminals the norm. Rain showers will be locally heavy, and
areas of fog are likely, especially near the coast. Low
conditions continue tonight with moist air mass remaining in
place. Some improvement... MVFR to possiblyVFR interior
terminals on Monday but the coast will likely hold on to lower
tue - thu... Areas of MVFR in shra tsra... With LCL ifr in
Short term... Prolonged southeast onshore flow will allow seas
to build today so a SCA for the outer waters has been issued for
late this afternoon into Monday.
tue - thu... Sca's are psb... Especially outside the bays.
Some smaller rivers and streams may need to be monitored today
through Monday as bursts of heavy rains and scattered
thunderstorms produce locally up to 1.5 inches of rain with some
locally higher amounts possible.

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.
