.NEAR TERM /THROUGH FRIDAY/...
-- Changed Discussion --
The primary concern in the near term is the threat of severe
thunderstorms today.

Upper level trough to our west will move east and cross the region
this afternoon. The atmosphere is expected to destabilize in
advance of the approaching upper trough and associated surface
cold front. This will result in scattered thunderstorms
developing, mainly after noon time. The primary threat with any
storms today appears to be the potential for strong to damaging
wind gusts. The Storm Prediction Center has placed all of
northern and downeast Maine in a Slight Risk for Severe
Thunderstorms today. Today has the potential to be the first
widespread severe weather event of the season, so please monitor
the latest forecasts on the potential severe weather threat
later today.

The severe weather threat should quickly wind down early this
evening as the cold front moves east. A few showers may linger into
early tonight, otherwise expect partial clearing late tonight.
Patchy late night fog will be possible. Lows tonight will
generally range from around 50 across the north and mid to
upper 50s for the Bangor region and Downeast areas.

A 500 MB low center will cross the region during Friday. Instabilty
associated with the cold pool aloft and diurnal heating will
result in the chance for showers and isolated thunderstorms,
mainly across northern and central areas. Freezing levels will
be lowering, so will have to watch for the potential of some
small hail with any isolated thunderstorms. Friday will feature
somewhat cooler temperatures. Afternoon highs will range from
around 70 across the north and the mid to upper 70s for the
Bangor region and Downeast.

.SHORT TERM /FRIDAY NIGHT THROUGH SATURDAY NIGHT/...
-- Changed Discussion --
The upper low which crosses the area Friday will be sliding
southeast of the region Friday night as high pressure builds to our
southwest. This will bring a mostly clear and seasonably cool night
Friday night. High pressure to our south on Saturday will bring a
mostly sunny and warm day as highs reach just above 80 inland.
A cold front will approach from the northwest Saturday night as
surface high pressure to our south slides east into the open
Atlantic. The gradient between the departing high and the
approaching cold front will bring an increasing southwesterly
breeze.

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
-- Changed Discussion --
A cold front will press into the area Sunday with showers and
scattered thunderstorms, mainly over the north. The front will
weaken and stall over the area Sunday night as it tries to press
south into high pressure to our southeast, as this high merges
with the subtropical high. A chance of showers will continue
Sunday night with the front stalled across the area. Some of the
forecast models are showing a weather disturbance tracking
along the front on Monday. This may continue the chance of
showers across the area with thunderstorms possible during the
midday and afternoon. The front will weaken and dissipate on
Tuesday although some isolated showers will continue to be
possible, mostly over southern areas. By Wednesday, very weak
high pressure will build over the region. This high will likely
not be strong enough to clear all the moisture over the region
so some clouds and isolated spotty showers may still be possible
with variable cloudiness and a chance of isolated showers
continuing into Thursday.
