...BEACH HAZARDS STATEMENT REMAINS IN EFFECT UNTIL 8 PM EDT THIS
EVENING...

* WHAT...Air temperatures in the 70s and water temperatures in 
  the mid to upper 50s expected..

* WHERE...Knox and Coastal Waldo Counties.

* WHEN...Until 8 PM EDT this evening.

* IMPACTS...The cold water temperatures can quickly cause 
  hypothermia to anyone immersed in the water. When the water
  temperature is below 60 degrees, the average submerged person
  could lose dexterity within minutes and be unable to accomplish
  simple tasks. Anyone on boats or paddlecraft 
  should use extreme caution to avoid this threat.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Beach Hazards Statement is issued on days when a significant
number of boats and paddlecraft are expected to be out on the
water and when warm air temperatures may cause people to
underestimate the danger of the cold water. Paddle smart from the
start. Always wear your life jacket. Be aware of wind conditions,
tides, and localized currents. 

All boaters and paddlers are highly encouraged to contact the
U.S. Coast Guard Auxiliary or U.S. Power Squadrons at
www.wow.uscgaux/i_want_a_usc/index.php to receive a FREE vessel
check. This is a convenient, no consequence way to ensure your
vessel is outfitted with all required safety equipment. 
Additionally, please label your paddlecraft with your contact
information (IF FOUND Sticker) in the event it is found adrift on
the water.

Area Forecast Discussion...UPDATED
National Weather Service Gray ME
1058 PM EDT Thu Jul 10 2025

.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 /UNTIL 7 AM FRIDAY MORNING/...
The shields were up and held for much of the evening across the
forecast area. The 11.00z GYX sounding observed nearly zero
instability...and SPC mesoanalysis placed a sharp north/south
gradient of MUCAPE just east of the CT River. As a result any
strong convection that did form over VT and eastern NY tended to
fall apart rather quickly as it approached. Now with the loss of
daytime heating and synoptic forcing for ascent weakening...I
have scaled back PoP overnight. It should not be much more than
isolated to widely scattered...and mainly confined to the higher
terrain if it does form at all.

Otherwise marine layer will continue to slosh back inland...with
clouds lowering already. Visibility will also tend to gradually
drop towards sunrise...so I added some areas of fog near the
coast...especially from Casco Bay and points south.

Today will see the slow eroding of the low clouds again. Daytime
heating will support scattered convection...largely tied to
terrain heating since we lack a more synoptic scale lifting
mechanism. There is a fairly well defined MCV present across
Lake Michigan at this hour...and that could spark more
widespread convection. Current model forecast have it over NY
in the afternoon...but it will warrant some monitoring this
morning to see if that forecast remains on track.

Winds will be a little more southerly than easterly today...and
so temps should be a few degrees warmer than what we saw
yesterday.

&&

.SHORT TERM /7 AM FRIDAY MORNING 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 /03Z FRIDAY THROUGH TUESDAY/...
Short Term...Highly variable conditions expected thru mid
morning. Closer to the coast and across southern NH areas of IFR
or lower will be possible due to marine fog and stratus.
Elsewhere some patchy MVFR CIGs are likely anywhere along and
south of the higher terrain. VIS/CIGs will scatter out towards
midday...but some lingering MVFR CIGs remain possible.
Scattered SHRA/TSRA are possible in the afternoon...but are not
likely at any particular TAF site. Fri night once again areas of
IFR are possible as marine moisture moves back inland. This will
tend to target more western ME...but I cannot rule it out as far
south as PSM. Similar scattering out is expected Sat...along
with scattered SHRA/TSRA during the afternoon.

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...Areas of fog will be possible over the coastal
waters...especially from Casco Bay south. Some improving
visibility is likely during the day...but fog is expected to
thicken and move back towards the coast during the evening and
overnight hours. This will tend to occur mostly north of Casco
Bay into Sat morning. Otherwise winds and seas will remain below
SCA thresholds.

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.

ME...None.
NH...None.
MARINE...None.
