Synopsis
High pressure ridges over the area tonight. A warm front will
lift northward across the area Monday. A cold front will cross
the region Monday night. High pressure will cross the
region Tuesday. A cold front will approach later Wednesday then
cross the region Thursday. Another cold front is possible
Friday.

Near term through Monday
The southerly onshore flow and elevated dew points will make
another round of fog and low clouds for tonight. It will start
near the coast where fog has remained all day and advect inland.

Fog and stratus will spread northward through the night,
covering the entire area after midnight. The denser fog will be
towards the coast and in higher upslope terrain. By late night
into the morning, a weak shortwave currently in upstate ny and
pa will propagate into the forecast area. This feature will
bring some morning showers and even higher dew points. Can't
rule out embedded thunder around hancock county near dawn. The
warm front will also prolong the duration of the low clouds
through the morning into the early afternoon and reduce
instability. The pre-frontal trough ahead of the cold front
will arrive in the afternoon. By that time, some clearing will
be possible along the western border of the forecast area. Bulk
shear will be increasing from the north during the afternoon and
will be favorable. Expect afternoon thunderstorms to develop
near the western border of the forecast area and move eastward
into a more stable environment towards the eastern border and
downeast during the late afternoon into the evening. The threats
with storms will be heavy precip and winds. Pws will be
approaching 2 inches in the afternoon ahead of the front. With
good surface heating bringing highs around 80f and dew points
near 70f, the best SBCAPE in the forecast area will likely be in
the southern half of piscataquis county, maybe spreading into
sw penobscot. In this area, a number of parameters such as 0-1km
shear and ehi, low lcls, sig tor and supercell composite
approach interesting values in some guidance, but the window of
opportunity is fairly narrow late in the day. SPC maintains the
forecast area in general risk for thunderstorms.

Short term Monday night through Wednesday
A weak cold front will cross the region Monday night, with high
pressure building toward the region late. Expect a chance of
showers thunderstorms with the cold front early Monday night.

Clouds then decrease overnight with building high pressure. High
pressure crosses the region Tuesday with mostly sunny skies.

High pressure moves to the east Tuesday night through Wednesday,
with a developing return flow across the region. Uncertainty
exists regarding a possible disturbance approaching the region
from the southwest Tuesday night. Expect partly cloudy skies
downeast Tuesday night, with mostly clear skies north. A cold
front crossing quebec province will approach the saint lawrence
river valley late Wednesday. The approaching cold front,
possible upper disturbance and diurnal instability will support
a chance of morning showers with a chance of afternoon
showers thunderstorms. Temperatures will be at near normal, to
slightly above normal, levels Tuesday Wednesday.

Long term Wednesday night through Sunday
The cold front approaches northern maine Wednesday night, then
crosses the region Thursday. Expect a chance of
showers thunderstorms in advance of the front. An upper low
moves northeast of maine Friday into Saturday, though the exact
track is uncertain. A disturbance moving around the low and a
surface cold front trof crossing the region could support a
chance of showers across mostly the north and mountains Friday.

Dependent on the proximity of the upper low, a slight chance of
showers could persist Saturday. High pressure will cross the
region later Saturday then begin to exit across the maritimes
Sunday with generally partly cloudy mostly clear skies. Expect
near normal level temperatures Thursday Sunday, with below
normal level temperatures Friday Saturday.

Aviation 20z Sunday through Friday
Near term: conditions will again deteriorate overnight with fog
returning to coastal sites such as bhb this evening. Fog and
ifr CIGS will move into bgr later this evening and overspread
all sites after midnight. Conditions will slowly lift Monday
morning, but will likely be slower to rise than today with the
warm front lifting north and some rain drizzle. Bhb could be ifr
all day. In the afternoon, concerns turn to thunderstorms
moving across the area ahead of cold front. Some of these storms
could be quite strong.

Short term:
Monday night... Occasional MVFR early with a chance of
showers thunderstorms.VFR late.

Tuesday...VFR.

Wednesday... GenerallyVFR. Chance of a shower thunderstorm.

Wednesday night through Thursday... Variable conditions with
showers thunderstorms.

Friday... GenerallyVFR. Occasional MVFR possible across the
north and mountains.

Marine
Near term: fog continues as the predominant issue over the
waters through Monday. Long period south swell continues near 3
to 4 feet. Winds will pick up towards 15 kts Monday afternoon.

There's a chance of thunderstorms arriving from the north by
evening.

Short term: winds seas will remain below small craft advisory
levels Monday night through Wednesday. Visibilities will be
reduced in fog Monday night. Could also have the chance of a
shower thunderstorm Monday evening, with another chance of
showers thunderstorms Wednesday.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
