Area Forecast Discussion
National Weather Service Caribou ME
241 AM EDT Tue Aug 12 2025

.SYNOPSIS...
High pressure will remain ridged southeast of the region
through tonight. A cold front approaches from the northwest on
Wednesday, then crosses the area Thursday. High pressure then
builds down from Quebec behind the front through Friday. High
pressure will shift overhead Saturday as a cold front approaches
from the northwest.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
...Heat Advisory continues today...

Upper ridge remains across the region today with a continuation of
sunny skies and hot and humid conditions. High temperatures this
afternoon are expected to once again climb into the low to mid
90s in most areas away from the coast. Apparent temperatures
will once again climb into the upper 90s in some locations, thus
the current heat advisories remain in effect. Record high
temperatures are once likely to be tied or broken, most
specifically for Caribou, Houlton, and Millinocket (please
refer to climate section below).

The upper ridge continues to break down tonight with another mainly
clear, unseasonably warm and muggy night expected. Patchy late night
fog not totally out of the question. Lows tonight are expected
to generally range from the mid to upper 60s across much of the
region.

Another hot and humid day is expected for Wednesday. Highs on
Wednesday are expected to be a few degrees cooler than those of
today, generally in the upper 80s to lower 90s. Thus, we will
likely remain just shy of heat advisory criteria, although it
will still be quite uncomfortable. Expect mostly sunny skies to
start, followed by increasing afternoon clouds ahead of an
approaching upper trough and surface cold front from Quebec.
Most guidance has now trended slower with the approaching front.
There will be the chance for showers or a thunderstorm later
Wednesday afternoon, mainly across the north Maine Woods. But at
this time no widespread strong storms are expected.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH THURSDAY NIGHT/...
The timing of the cold front has slowed from previous model
runs, so it is not expected to cross the area until early
Thursday morning. Thunderstorms developing in the warm sector
ahead of the front will persist through Wednesday evening,
turning into showers overnight as solar heating is lost and CAPE
decreases. On Thursday, showers and thunderstorms will continue
across the region just ahead of the cold front. There is not a
lot of bulk shear associated with the system at this point, so
the possibility of severe weather is limited, although one or
two storms could put out some gusty winds with precip loading in
the downdraft. That being said, the storms with the heaviest
precip are more likely to occur on Wednesday and Wednesday
evening in the warm sector, when the warm cloud layer will be
thickest and PWATs are closer to 1.75 inches. Overall this does
not look like a significant chance for severe thunderstorms or
flash flooding.

In terms of QPF, the forecast has become a little more positive
for our drought-risk areas with some QPF now showing along the
southern edges of the front, possibly due to the overnight
frontal passage. Total QPF amounts will still be less than 0.5"
in the north and closer to 0.2" across Downeast and Bangor, so
this will by no means make up for the current precip deficit in
these areas. Still, it will hopefully provide a little relief
for these extra dry locations.

&&

.LONG TERM /FRIDAY THROUGH MONDAY/...
The cooler air will persist through Friday, but by Saturday
temps will slightly rise in as the high builds in from Quebec.
On Sunday, another cold front will cross the region, bringing
another chance for showers and thunderstorms. Although this
front is a little stronger in terms of a temperature drop, it
still does not look like it will be a drought buster. Monday and
Tuesday will feel quite cool compared to the hot temperatures
from this week, with highs only reaching the upper 60s to mid
70s. Northerly winds behind the front on Monday could be a bit
gustier than we have seen in recent frontal passages, perhaps
gusting to 20 mph in the north. This could be impactful for fire
weather, in particular if the current QPF forecast pans out in
terms of minimal rainfall amounts between now and then.

&&

.AVIATION /06Z TUESDAY THROUGH SATURDAY/...
NEAR TERM: VFR conditions are once again expected at all the
terminals through Wednesday. The only exception is the
potential for patchy late night or early morning fog, especially
vicinity KBHB. S to SW wind 5 to 10 kt through Wednesday.

SHORT TERM:

Wed night-Thu...MVFR in rain showers and possible
thunderstorms. S winds 5-10 kts, switching to W on Thu.

Thu night-Sat...VFR. NW winds 5-10 kts, then SW on Sat.

&&

.MARINE...
NEAR TERM: Winds/seas are expected to remain below SCA levels
through Wednesday. Patchy late night and early morning fog may
reduce visibility to 1NM or less at times.

SHORT TERM: Winds and seas will remain below SCA conditions
through this time period.

&&

.CLIMATE...
Record high temperatures are possible in some locations
Tuesday.

Record Highs for today Aug 12:

Caribou: 93 in 1944, forecast high 93
Houlton: 92 in 2020, forecast high 94
Millinocket: 94 in 1944, forecast high 95
Bangor: 100 in 1944, forecast high 95
