Area Forecast Discussion
National Weather Service Boston/Norton MA
141 AM EDT Fri Jul 13 2018

.SYNOPSIS...
High pressure brings dry weather with seasonable temperatures
and comfortable humidity through Saturday morning. Hit or miss
heavy rainers and thunderstorms are possible at times over the
weekend into next week. Near or above seasonable conditions
throughout.

&&

.NEAR TERM /THROUGH TODAY/...
10PM Update...
No significant changes to the previous forecast. Most of the
diurnal clouds have since dissipated across the region, apart
from some high level clouds that continue to linger across
northern MA. High pressure continues to move eastward over the
northeast providing clear and dry conditions through tonight
for much of SNE. However, fog remains possible for parts of the
region, especially along the coast and SE MA and as onshore
winds drop below 5kts.

Previous discussion...
Main concern revolves around present onshore sea-breezes.
Dewpoints have jumped up as high as 10 degrees into the upper
50s, especially around Narragansett Bay. With radiational
cooling on tap and forecast lows down into the low to mid 50s
for typically prone spots, there is the threat of shallow ground
fog for some locations. Per the rapid refresh short-term
ensemble, or NARRE, the risk appears greatest for SE-coastal New
England where presently dewpoints have risen. Visibility less
than 4 miles is entirely possible. Can't rule out issues for
some of the Islands especially Marthas Vineyard.

&&

.SHORT TERM /TONIGHT THROUGH 6 PM SATURDAY/...
Trough moves off to the east of our area while upper ridge moves
in. Expect sunny skies and dry weather with another round of
diurnal cumulus for the midday and afternoon. The mixed layer
once again goes deep, up to 800 mb, tapping similar temperatures
to today...thus supporting max sfc temps in the upper 70s to mid
80s inland. Light flow at the surface will again allow sea
breezes along the coast with sfc temps in the 70s.

Still under the influence of the ridge, we expect quiet weather
for Friday night with light surface flow. Temps will cool to
between 55 and 65 degrees.

&&

.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
*/ Highlights...

 - Weekend hit or miss heavy rainers, thunderstorms
 - Tuesday sweeping line of heavy rainers, thunderstorms
 - Late week shot of wet weather
 - Near or above seasonable conditions throughout

*/ Overview...

Weekend into following week scattered showers and thunderstorms at
times. Interrogating the atmosphere, interestingly a phase 5/6 MJO
however lately we've seen strong H85 and H2 westerly anomalies for
early July over the N Pacific and CONUS, negligible anomalies along
the equator. Signals that suggest excessive heat, humidity remain
out of our region. More notable is a +2 AO. Dominant polar low with
a negative anomaly extending on up through the stratosphere. Take-
away are less pronounced trof-dips across the N Hemisphere. So its
no surprise ensemble means signal near-zonal flow from the N Pacific
through the CONUS with a subtle H5 trof pattern and weak wave action
over the E-half of N America into late July.

That being said, forecasting a series of sweeping weak disturbances
for the foreseeable future. Trailing cold fronts along which we'll
see hit or miss heavy rainers, thunderstorms followed by refreshing
airmasses.

*/ Details...

The weekend looks busy with hit or miss elements, perhaps Saturday
associated with remnant MCS activity that re-flares over-night into
Sunday round a dominant SE-CONUS H5 ridge. Better chances of W wet-
weather outcomes. While on Sunday a stout H5 trof axis digs in from
the N renewing focus. Marginal shear, weak steering flow throughout.
Precipitable waters up to 2-inches. Watching K-indices, high values
of theta-E. Hit or miss, heavy rainers and thunderstorms, perhaps
gusty winds.

Over the week, another sweeping cold front Tuesday, more pronounced,
perhaps late. SW inflow of decent moisture, instability. Marginal
shear, however good lift and forcing, seemingly better chances of
widespread outcomes rather than hit or miss. Looking like a line of
convective outcomes.

Another round of wet-weather by the end of the week. Further out in
time, a low confidence forecast however looking like Friday impacts.

.TIDES/COASTAL FLOODING...
Astronomical tides will be rather high during the night time
high tide cycles tonight through Sat night. Fortunately wave
action will not be much of a factor and surge is limited.
However, leftover SE swell may result in minor splashover for
vulnerable areas along east coastal MA tonight.

Tides are slightly higher Fri night and Sat night so additional
rounds of splashover are possible during these high tide
cycles.

Interesting to note...astronomical high tides will again be
high in mid-August but a little lower than the current set of
astro tides. The next set of high astronomical tides in Jan-
Feb will be lower than the August tides. This trend to lower
values for the high astronomical tides continues through the
end of 2019.
