.DISCUSSION...
KEY MESSAGE 1...Thunderstorms, some severe producing damaging
winds, will continue for the next hour or two mainly over
Downeast areas.

KEY MESSAGE 1 DESCRIPTION...
Main cold front located along the coast with temps dropping into
the 60s behind it. Secondary cold front located along the St.
Lawrence with dewpoints currently in the 30s. Ongoing
thunderstorms will shift south over the waters by evening. These
storms may still have the potential to produce damaging winds
as they exit the area this afternoon.

KEY MESSAGE 2...Next chance for showers and thunderstorms will
be Saturday afternoon into Sunday, with locally heavy rain
possible Sunday night.

KEY MESSAGE 2 DESCRIPTION...
The next chance for showers and storms is this weekend as low
pressure moves in from the Great Lakes. Thinking that since the
greatest forcing will arrive overnight, thunderstorms will be
more isolated although cannot rule out some thunder with
elevated instability Saturday night. PW values of 1.50+ inches,
which is > 90th percentile for this time of year. Locally heavy
rainfall is possible with any storm as storms train over the
same area. QPF amounts range from 0.80-1 inch from Katahdin to
Houlton north with 0.50-0.75 inches to the south. WPC has
included the northern areas in a marginal risk for flash
flooding mainly for Saturday night.
