Synopsis
A tropical air mass will remain in place through at least mid
week with scattered tropical downpours in showers and thunderstorms
each day, mainly across interior sections. A cold front slowly
crosses the area Friday then moves offshore over the weekend. In
its wake a much drier and more comfortable air mass will move
into place.

Near term until 6 pm this evening
Update...

have updated the forecast based on current conditions and latest
set of mesoscale models. Showers continue, mainly over far
northern and western portions of our forecast area. Will
continue this trend this afternoon, with some of the showers and
widely scattered thunderstorms producing locally heavy rainfall.

Along the coast and the rest of southern maine and southeast new
hampshire, an onshore flow and lack of any dynamics should
prevent most of the precipitation from effecting the region,
despite a deep, tropical airmass in place.

Made minor adjustments to MAX temperature, dew point and cloud
cover forecasts for today as well. Temperatures will reach the
lower 80s over southern new hampshire and portions of the
connecticut river valley once again today.

Prev disc...

600 am... For this estf update I ingested the current mesonet
into near term grids.

Prev disc...

at 06z... GOES water vapor imagery showed an upper low over the
eastern great lakes with an upper high centered over the western
atlantic. Between these two features a deep plume of tropical
moisture with pwats from the 00z raobs near 2 inches being
transported northward along the eastern seaboard. NWS doppler
radar mosaic showed areas of convection continued to break out
and track northward in this rich moisture plume. Instantaneous
precipitation rates of up to 2 inches per hour have been noted
by nearby radars. Fortunately... Convection has been fast moving
and brief resulting in hourly amounts well under that amount.

The issue through today will be areas that see frequent repeat
or training echoes where localized amounts of 2 to 3 inches
can't be ruled out... Along with potential for localized drainage
and small stream flooding and ponding of water. Available
guidance... Including the hires short range models... Suggest the
convection will become more scattered and shift further west
today in response to the upper trough closed low and offshore
ridge retrograding westward. This should help mitigate the
potential for flooding across much of the cwa. Otherwise... It'll
be a mostly cloudy and humid day with highs mainly in the 70s.

Short term 6 pm this evening through 6 pm Tuesday
Widespread fog and haze in our tropical airmass tonight as the
upper ridge continues to retrograde westward. There could be a
brief shower or thunderstorm this evening... Otherwise just a
warm humid night with some patchy drizzle. Lows in the mid 60s
to lower 70s. On Tuesday... The fog and haze should lift with a
mix of clouds and sunshine. The ridge should limit convective
potential... Especially along the coastal plain with only
scattered convection expected inland. With some sunshine and
only widely scattered convection expected... We'll be quite a bit
warmer than today with readings mainly in the 80s. When
combined with dewpoints near 70f... It'll feel downright
oppressive with apparent temperatures heat indices in the upper
80s and lower 90s in many locations away from the coast.

Long term Tuesday night through Sunday
After getting a bump W early this week... Deep sly flow and high
pwat air mass will move back across the area for the middle of
the week. The moisture plume will be ushered along the by next
approaching S WV trof... Set to cross the area late Wed into thu.

Deterministic and ensemble guidance are in agreement that pwat
values make another run at 2 inches across much of the forecast
area. Given the broad agreement... I have included enhanced
wording for heavy rainfall into early thu. This air mass will
also likely bring continued mild nights and new rounds of
fog low clouds. The high dewpoints will also allow for at least
marginal CAPE to develop in the afternoons... Despite meager
lapse rates in the moist environment. That will likely keep any
severe threat more on the localized scale than a more widespread
threat. But given the amount of precip loading possible... Any
stronger convection will need to be watched for some gusty
winds.

After thu... Model forecasts bring a much drier... Continental air
mass into the region. This will bring some relief from the muggy
air... And also cut down the significant rain chances.

Aviation 14z Monday through Friday
Short term through Tuesday ... Ifr lifr conditions in areas of
stratus and fog along with sct shra tsra. Conditions improve to
vfr on Tuesday wth LCL MVFR in -shra -tsra.

Long term... Will likely see another round of ifr conditions wed
into Thu as deep moisture sloshes back across the area from the
w. Areas of fog stratus should develop along the coast and
extend inland ahead of the next approaching S WV trof late wed.

The chances for shra tsra will also increase thru the day wed
into Thu as the surface front approaches. At this time +ra looks
to be a threat in any convection... And local ifr or lower
conditions as a result.

Marine
Short term through Tuesday ... Have added patchy dense fog to
the marine forecast. Otherwise, will continue the SCA for haz
seas for the outer waters through tonight. The onshore flow,
although generally only 10-20 kt, and long southeast fetch will
continue to produce seas of 3-6 ft.

Long term... Flow will remain stubbornly sly thru the middle of
the week. This will keep areas of fog across the waters with the
high dewpoint air mass in place. It will also gradually build
seas. As nearshore waves start to creep towards 5 ft... A
moderate risk for rip currents may develop.

Hydrology
Showers and a few thunderstorms will continue, mainly over
northern and western portions of our forecast area. Rivers
remain relatively low with our recent dry conditions. Away from
the coast... Thunderstorms could produce locally heavy rainfall
which could adversely affect low lying and urban areas.

Otherwise... We'll need to watch for training echoes which could
result in localized flooding concerns.

Gyx watches warnings advisories
Me... None.

Nh... None.

Marine... Small craft advisory for hazardous seas until 2 am edt Tuesday
for anz150-152-154.
