.NEAR TERM /THROUGH TODAY/...
130 AM Update: Mid to upper level cloud cover continues to clear
out from north to south tonight as the previous low pressure
system presses further east into the Canadian Maritimes. Current
Nighttime Microphysics RGB satellite product shows low level fog
development in river valleys across the North Woods, and current
trends from the KPQI ASOS indicate that fog is building into the
valleys over eastern Aroostook county as well. The previous
forecast remains largely on track with only minor adjustments
based on current observations and trends.

Previous Discussion:
Sfc low continues to sit and spin over the Downeast coast. Low
clouds are very slowly clearing acrs the north and will likely
continue to do so this evening as lopres sinks south over the
waters. Expecting skies to clear over the north right around
daybreak with patchy fog developing as winds become light and
variable. Light stratiform rain over the north, though honestly
hard to believe much is reaching the ground, will continue to
sink south this evening.

Further to the south convective showers have developed along
boundary over interior Downeast and will continue to pivot over
this area remainder of the afternoon and into the early evening
hours. Have included isolated thunder with locally heavy
rainfall in areas that continue to receive rainfall but overall
threat for this is very low.

Temps will remain above normal mins for tonight, although the
North Woods may be able to drop into the upper 40s depending on
timing of clearing skies. Most of the western zones will see
sunny skies at daybreak tomorrow while southeastern areas will
see showers initially before clearing by noon. High temps over
the area likely to top out in the lwr 80s though the shore will
only rise to around 70 degrees.

Saturday night though timing differences with the front still exist.
Expect partly cloudy skies early Saturday, with clouds then
increasing during the afternoon. Dependent on the eventual
timing of the front, could also have a slight chance/chance of
showers across mostly western portions of the forecast area
