National Weather Service Caribou ME
1024 PM EDT Thu Jun 26 2025

Sunday and Sunday night. A warm front will cross the area
Monday into Tuesday.

.NEAR TERM /THROUGH FRIDAY/...
-- Changed Discussion --
10 PM Update: Mostly clear skies now persist across the forecast
area. With surface decoupling in place, temperatures have begun
to quickly drop. Min temps were lowered slightly with this
update based on current observations and trends. Some patchy
frost could develop in the sheltered valleys of the North Woods
late tonight, but any that does develop will be brief and
quickly dissipate with sunrise.

Previous Discussion:
Surface high pressure remains ridged across the region tonight
into Friday. An upper level disturbance will exit the region
early tonight with decreasing mid/high level clouds in the wake
of the disturbance. Mostly clear skies will then occur
overnight. Low pressure across the Great Lakes will begin to
draw a warm front toward the region later Friday. After a mostly
sunny morning, clouds will increase Friday afternoon. Low
temperatures tonight will generally range from around 40 to the
lower 40s across northern areas. However, localized upper 30s
are also possible across the normally coldest northwest valley
locations. Low temperatures Downeast will range from the upper
40s to around 50. High temperatures Friday will range from
around 70 to the lower 70s north, to the lower to mid 70s
Downeast.

.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/...
Clouds increase Friday evening in advance of low pressure advancing
east from the Great Lakes region. At the same time, high pressure
will continue to slide east into the western atlantic to the
south of Nova Scotia. A south to southeast flow around these
systems will result in increasing precipitable water values (1.0
to 2.0 inches) across the region Friday night. Rain is expected
to develop Friday evening, with the greatest rain chances
across the western portions of the forecast area, where the best
lift will be focused in advance of the developing warm front.
Saturday is expected to be an unseasonably cool, cloudy, and
damp day. The best lift/focus for rainfall will continue to be
across the central Maine Highlands and Downeast areas, in the
vicinity of the boundary, with lesser chances further north.
Rainfall totals through Saturday night are expected to range
from less than one-quarter inch across the St. John Valley, and
from one-inch to an inch and a half across the rest of the
region. Some locally higher amounts are possible across the
higher terrain of Piscataquis county in the favored upslope
regions. Unsettled and damp weather conditions are expected to
continue, at least through early Sunday until the 500 MB short
wave moves east.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
Ridging builds in Sunday night through Monday, with a drying trend
expected. It will become a bit more humid. Another frontal
boundary approaches from the west later Monday night and
crosses the region Tuesday into Tuesday night. Expect an
increasing chance for showers later Monday night and the chance
for showers and thunderstorms on Tuesday. Another weak ridge
build in for Wednesday night into early Thursday, before the
next system crosses the region by Thursday. Afternoon highs
will be near to a bit above normal for this time of year.
