.SYNOPSIS...Scattered showers will continue into tonight along
with low clouds and fog. Clearing tomorrow except for a isolated
shower across the interior in the afternoon. The Bermuda high
will be in place through the weekend, supplying mostly dry and
warm weather. The ridge breaks down for the start of the new
work week, with a return of hit and miss showers. Heat will
begin to build by the middle of the next week once again.
&&
.NEAR TERM /THROUGH TONIGHT/...
This evening there is the diminishing chance for locally heavy
rain north of the Whites and across the CT River Valley. Storm
motion has been rather slow today with heavy rain showers
anchoring on the terrain causing the heavier showers to drop
close to 2" per hour rainfall. A few localized areas across
Northern NH have received some heavy rain already today, so
threat is if the same area gets hit again. Overall threat is
very isolated, but a Flash Flood Warning can`t be ruled out at
this time as the mid- level short wave is still moving across
the region. Second sensible weather impact is the potential for
locally dense fog developing tonight along the coast. HREF props
are showing a good push of low visibilities tonight and marine
stratus is hanging along the coast today. LAMP guidance is also
very low. Will have to see how dense the fog becomes tonight.
&&
.SHORT TERM /FRIDAY THROUGH FRIDAY NIGHT/...
Weather Impacts:
* No significant weather impacts expected
* Dense morning fog on the coast can`t be ruled out
Friday...Shortwave trough pushes through for tomorrow with
westerly flow expected. Slightly drier air moves into the region
with partial clearing expected as morning fog and stratus burns
off. This should lead to clearing by the afternoon for all
areas. CAM guidance shows potential for a few convective
showers or weak storms over the terrain tomorrow afternoon.
Overall areas coverage looks limited and severe parameters are
weak. Not expecting and significant storms at this time but will
let the night shift take another look.
Friday Night...Clearing is expected, with potential for some fog
development. Overall no weather impacts expected with high
pressure in control.
&&
.LONG TERM /SATURDAY THROUGH THURSDAY/...
Overview: High pressure will be over the Gulf of Maine come
Saturday morning. This will keep mostly dry conditions through the
forecast area Saturday and Sunday, but will need to watch for
afternoon showers or storms near stalled boundary to the west.
Additional showers and storms will organize along a incoming cold
front Sunday night through Monday. This front will lead to broad
ridging into midweek, allowing for another potential stretch of day
with hot temperatures.
Details: Saturday: While high pressure will be moving out of the
Gulf of Maine through the day, onshore flow and high PWATs over the
region will tend to bring afternoon showers or thunderstorms. Global
models are hinting at a rather large footprint of QPF in NH through
the afternoon and early evening. However in the absence of better
jet dynamics and lifting feature, believe precip chances will lie
close to topographic features vs. a widespread rainfall. This also
aligns with diurnal trend of instability before coverage tails off
in the evening.
Sunday-Monday: A cold front will advance eastward out of the Great
Lakes Sunday. Ahead, onshore flow moderates temperatures w/ areas
remaining dry through much of the afternoon. PoPs begin to increase
into the evening hours as weak forcing arrives while any daytime
instability remains. Presently little conviction on coverage here as
low levels are dry.
Present rain chances focus on Sunday night-Monday associated with
the frontal approach through Mon evening. Because the parent low
drives north and occludes over Hudson Bay Sunday, forward
progression slows. The result is precip influence from the boundary
potentially through Mon night into Tuesday. There will be
instability ahead of the front to bring the chance for thunder,
mainly during the afternoon. Elevated instability will bring the
chance for a few rumbles overnight and evenings as well.
On the heels of that weather maker, a return to hot temperatures
appears likely should the front move through by Tuesday afternoon.
Daytime highs into midweek could again top out in the upper 80s to
lower 90s with dewpoints reaching the upper 60s to around 70 degrees.
&&
.AVIATION /19Z THURSDAY THROUGH TUESDAY/...
Short Term...IFR and LIFR expected at most TAF terminals tonight
as the marine layer surges back into the area with low ceilings
and possible fog formation. Conditions improve by tomorrow
morning
Long Term...MVFR to IFR ceilings return Friday night into
Saturday morning. Additionally, stratus may build down during
the late evening hours leading to vis restrictions due to fog.
While fog will tend to thin into the Sat morning hours,
ceilings remain MVFR to IFR through the day. LIFR is probable
Saturday night along with additional fog development.
&&
.MARINE...
Short Term...Fog is expected across the coastal waters tonight.
Improving visibility is expected tomorrow through the weekend.
Overall seas and winds will remain well below SCA conditions
with high pressure in control.
Long Term...Conditions remain below SCA through the period.
There will be the chance for marine stratus and fog to cause
reduced visibility through this weekend and into early next
week.
&&
