.DISCUSSION...
KEY MESSAGE 1...Warm and dry this weekend through early next
week.

KEY MESSAGE 1 DESCRIPTION...
The upper level trough will finally exit to the east this
weekend. A broad ridge of high pressure will settle in its
place. This will lead to a southwest dominant flow across our
forecast area, advecting warm air into the region. The
particular airmass that is entering the region will contain
abnormally warm temperatures across the eastern half of the
CONUS. For our area, at the northern end of the ridge,
temperatures will rise above average by around 5 degrees or so.
This may lead to temperatures into the low 70s across the region
this weekend. If the departing upper level trough takes longer
to shift east or the center of the incoming high pressure sets
up further south, these temperatures may not warm as much. If
the ridge that develops is stronger than currently projected, it
may have a more dominant influence over our forecast area and
temperatures could trend warmer than currently projected.

Skies will be mostly clear during the subsidence pattern into
this weekend, with limited available atmospheric moisture as
PWATs are forecast to be less than 1 inch, falling to less than
a half inch by Sunday night into Monday. Some fair weather
cumulus may develop during Saturday afternoon. On Sunday, a weak
trough will move through the area which could bring isolated
light rain showers early Sunday morning before conditions dry
out once more into Sunday afternoon, along with continued wind
gusts up to 30 mph. Heading into Monday, there exists the
potential for rapidly dropping dewpoints resulting in relative
humidity that could plummet below 30 percent, as forecast
soundings show steep lapse rates and a deep pocket of dry air in
the mid levels.

KEY MESSAGE 2...Scattered thunderstorms possible Tuesday and
Wednesday afternoons.

KEY MESSAGE 2 DESCRIPTION...
Southwest winds return the warm, more moist air advection to
the area Tuesday into Wednesday, re-energizing the atmosphere
with fuel that could support isolated thunderstorm development.
Early global guidance suggests CAPE values could approach 1000
J/kg with around 40 kts of bulk shear, and these ingredients
could help with not only thunderstorm development but sustaining
thunderstorms for a longer duration. Thunderstorms could be
possible across the forecast area, but forcing and available
moisture will be greatest in the north closer to the lingering
warm front.

...National Weather Service Cold Water Safety Message...

* The warm air temperatures this weekend in the upper 60s to mid 70s may
  cause people to underestimate the dangers of the cold water
  temperatures which are currently only in the mid 40s on the lakes
  and in the mid 40s on the rivers.

* The cold water temperatures can quickly cause hypothermia to
  anyone immersed in the water. According to the Maine Warden
  Service, when the water temperatures are below 50 degrees, the
  chance of immediate incapacitation due to cold shock is extremely
  high. Anyone on small boats, canoes or kayaks should plan
  accordingly if recreating this weekend and use extreme caution to
  avoid this threat. Paddle smart from the start and always wear
  your life jacket!
