Area Forecast Discussion
National Weather Service Caribou ME
220 AM EDT Mon Aug 11 2025

.SYNOPSIS...
High pressure will remain ridged southeast of the region
through Tuesday night. A cold front approaches from the
northwest on Wednesday, then crosses the area Wednesday night
and Thursday. High pressure then builds down from Southeastern
Canada behind the front through Friday.

&&

.NEAR TERM /THROUGH TUESDAY/...
...Heat Advisories continue through Tuesday...

Hot and Humid weather continues today through Tuesday. 500 MB ridge
will remain across the region as surface high remains off the mid
atlantic coast. 925MB temperatures max out at around 27C across the
interior yielding high temperatures this afternoon and again
Tuesday afternoon in the lower to mid 90s. Dew points in the
upper 60s to near 70 will result in very uncomfortable
conditions this afternoon. Apparent temperatures will range
from the mid 90s to perhaps near 100 degrees in some areas
inland from the coast. Tonight will be mainly clear and muggy.
Some late night patchy fog is possible along the coast. Lows
tonight will fall back into the mid to upper 60s in most areas.
The upper ridge begins to weaken somewhat by Tuesday but it will
still be another hot day with afternoon highs in the low to mid
90s for much of the region inland from the coast.

&&

.SHORT TERM /TUESDAY NIGHT THROUGH WEDNESDAY NIGHT/...
Warm temperatures will continue Tuesday night through Wednesday
night, with southwesterly flow ahead of an approaching front.
Overnight lows both Tuesday night and Wednesday night will be in
the low to mid 60s across the region, and with dewpoints in the
same range, there will not be much relief from daytime
mugginess. Highs on Wednesday will be very slightly lower than
Tuesday, but still close to 90 across the board and the heat
advisory may need to be continued. Wednesday night, a pre-
frontal trough will cross the area, bringing the possibility of
showers and thunderstorms. However, models continue to show this
shortwave weakening and drying out as it moves into the high, so
precipitation may be somewhat limited. It appears that the
heaviest rainfall will be restricted to the mountains, the North
Woods and northeastern Aroostook County, so Bangor and Downeast
are unfortunately not going to see much relief from the
developing drought.

&&

.LONG TERM /THURSDAY THROUGH SUNDAY/...
On Thursday, the main upper level trough will cross the area and
bring some relief for the heat. The chance for showers and
thunderstorms extends through Thursday, although again, QPF
amounts look negligible and this is not promising for drought
relief. Temps Thursday through Friday will be closer to normal,
and dewpoints will drop significantly, making the air mass a
more comfortable one. High pressure will build back in over the
area Friday afternoon and Saturday, so temperatures will
gradually increase, but are unlikely to return to the highs seen
earlier in the week. The next chance for a front bringing
showers and thunderstorms will be on Sunday, with a stronger
cold front expected to cross the region. This may bring a little
more rainfall to all areas as well, but really is the first
chance for improving dry conditions for the whole week.

&&

.AVIATION /06Z MONDAY THROUGH FRIDAY/...

through Tuesday. the only exception is the possibility of
