Area Forecast Discussion
National Weather Service Caribou ME
948 AM EDT Thu Aug 4 2022
.SYNOPSIS...
A cold front will approach today, then begin to cross the area
tonight. The front will stall across Downeast areas later
tonight into Friday. The front will dissipate Saturday while
high pressure builds to our southeast. Low pressure will
approach on Sunday and slide south of the area Monday.
&&
.NEAR TERM /THROUGH TONIGHT/...
9:48 AM Update: Fog continues to erode along the coast this
morning as the sun rises and winds begin to increase. Mostly
clear skies will return Downeast, while overcast skies move in
across the north ahead of the approaching cold front.
Temperatures and sky forecasts were refreshed with this update
to reflect current observations and trends, but no major changes
needed to the previous forecast. Hot and humid conditions are
still expected for most of the forecast area.
Previous Discussion...
Hot and humid today. No changes to the Heat Advisories. A slow
moving cold front will approach northern Maine today. The front
will begin to cross the region tonight, stalling across Downeast
areas late. Scattered showers and thunderstorms will develop
across mostly northern and central areas this afternoon in
advance of the cold front. Precipitable water values will
increase to 1.50 to 1.75 inches this afternoon. These
precipitable water values and possible training thunderstorms
could produce locally heavy rains this afternoon into the
evening. Gusty winds are also possible with any stronger
thunderstorms, particularly in the vicinity of any collapsing
thunderstorms. Low clouds and fog will occur Downeast this
morning. Expect mostly/partly sunny skies this afternoon along
with hot and humid conditions. The showers thunderstorms will
weaken while sinking south with the front overnight, with
isolated/scattered showers and thunderstorms possible across the
entire forecast area. High temperatures today will range from
the mid 80s to around 90 north, to around 90 to the lower 90s
interior Downeast. Temperatures along the Downeast coast will
generally range through the 80s. Low temperatures tonight will
range from around 60 the mid 60s north, to the lower to mid 60s
Downeast.
&&
.SHORT TERM /FRIDAY THROUGH SATURDAY/...
A cold front will stall near the Downeast coast on Friday as weak
high pressure pushes into southern Quebec. The front will bring a
partly to mostly cloudy sky in southern areas with some showers and
isolated thunderstorms while moderately drier and cooler air pushes
into the far north. High pressure will crest across the north
overnight Friday night pushing the front just a little further south.
This will bring a mostly clear and cool night over the north as lows
drop into the mid 50s while southern areas remain partly to mostly
cloudy and more humid with isolated showers. The front across the
south will dissipate on Saturday as subtropical high pressure off
the Mid Atlantic coast pushes warm and humid air back north on a
southwesterly breeze. High pressure building into western Quebec
will push a new cold front toward the area Saturday night. We will
remain in a warm and humid airmass with a light southwesterly breeze
overnight. This will prevent the air from cooling much with lows
Saturday night expected to be in the upper 60s throughout the
area.
&&
.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
The cold front will continue to approach on Sunday possibly
bringing some showers and isolated thunderstorms across the
north Sunday afternoon. Weak high pressure will settle over
southern areas. Sunday will be very warm and humid possibly
requiring heat advisories again for parts of the interior south.
Highs will range from the mid to upper 80 north to the low 90s
over the interior south with apparent temps likely rising into
the mid 90s in some southern sections. Our focus for the start
of next week turns to a shallow but moist low pressure system
approaching from the Great Lakes. Ahead of the low, the cold
front will slowly push south Sunday night reaching the coast by
early Monday. This will bring some cooler air into the north
while Downeast remains warm and humid. Some showers will likely
accompany the push of the front across the region Sunday night.
The front will slowly press offshore and dissipate on Monday as
low pressure begins to approach from the west. The low will
track to our north later Monday into Monday night pulling warm
and humid air back north across the area and bringing a chance
of showers to the region. This low will pull a new cold front
into the region later Tuesday possibly bringing a concentrated
area of showers and thunderstorms as the low tracks through
pulling the front across.
