National Weather Service Caribou ME
457 AM EDT Sun Jun 25 2017

An upper level disturbance will cross the region today. A cold
front will begin to cross the region Monday.

A weakening slow moving cold front will remain across central
portions of the forecast area today, while an upper level
disturbance crosses the region. Skies will be mostly sunny this
morning. Scattered showers and thunderstorms will then develop
this afternoon along with partly sunny skies. Scattered showers
and thunderstorms will persist this evening. Another cold front
will approach northern Maine late tonight which will keep a
chance of showers across mostly northern areas overnight. High
temperatures today will range from the lower to mid 70s north,
to the upper 70s to around 80 interior Downeast with mid to
upper 70s along the Downeast coast. Low temperatures tonight
will range from around 50 to the lower 50s north, to the mid 50s

A cold front is expected to approach from the northwest Monday
then become stationary across the region. Low pressure will
develop and move northeast along the front later in the day
Monday. This is expected to produce showers across the area
Monday night and into Tuesday. Thunder is also possible Tuesday

An upper level trough is expected to move across the region
Tuesday night resulting in more showers. A second upper level
system will approach from the west and move across the area
Wednesday with additional showers. More showers are then
expected again on Thursday as a third area of weak low pressure
moves across the state.

NEAR TERM: Locally variable conditions could occur with any
patchy fog early this morning. Variable conditions will also
occur with any showers or thunderstorms this afternoon into
early tonight. Otherwise, generally VFR conditions are expected
today through much of tonight. Occasional MVFR conditions are
possible across the north and mountains later tonight.

SHORT TERM: VFR conditions are expected Monday. MVFR/VFR are
expected Tuesday through Thursday.

NEAR TERM: Winds/seas will remain below small craft advisory
levels today through tonight. Visibilities could be locally
reduced in any showers or thunderstorms later this afternoon
into early tonight. Patchy fog is then possible later tonight.

SHORT TERM: Have used the NAM to initialize sustained wind
speed. Will lower model wind speed by 10 percent due to cold sea
surface temperature. Will transition to super blend winds late
Tuesday. For Waves: South to southwesterly wind wave is expected
to be the primary wave system Monday through Thursday. A
secondary long period swell system (1-2 feet/10-12 seconds) is
possible Wednesday and Thursday. Will use the Nearshore
Prediction System for wave heights Monday and Tuesday then
transition to the Wave Watch III late Tuesday.
