.DISCUSSION...
KEY MESSAGE 1...Dry conditions and seasonable temperatures are expected
through early next week.

Surface high pressure continues to build north of the forecast
area through the end of the week, yielding dry conditions,
seasonal temperatures, and limited cloud cover. High
temperatures will be in the 60s to near 70s each day with
overnight lows in the 30s to mid 40s.

High pressure will build southward out of southeastern Canada and
eastern Great Lakes region Saturday through Tuesday. Dry conditions
are expected each day. There could be some areas of frost Saturday
morning. Temperatures will start out chilly Saturday with highs 5 to
7 degrees below average and highs generally in the upper 50s to
lower 60s. By Sunday, temperatures will be more seasonable. Monday
will encounter highs approaching or reaching the 70 degree mark. By
Tuesday, temperatures may be knocked down to seasonable once again.
Highs in the middle 60s.

.AVIATION /06Z WEDNESDAY THROUGH SUNDAY/...
VFR conditions continue as surface high pressure builds overhead
and dry conditions persist. Winds remain primarily out of the
north today before shifting to northwesterly on Thursday. On
Friday, winds shift to northeasterly. Terminals located near the
I-95 corridor will gust around 15 knots each afternoon.
Otherwise, terminals can expect light northerly winds, no
precipitation, and VFR conditions.

VFR conditions Saturday through Sunday night. Winds light and
variable through the period.

&&

.MARINE...
The Nor`easter off the Mid-Atlantic coast will deliver a
prolonged period of SCA conditions (mainly over the
central/lower waters). Small Craft Advisories remain in effect
and will likely need to be extended. The threat is highest in
the lower portions of the waters, with additional Advisories
possible through the end of the week. Otherwise, dry conditions
and non-hazardous marine weather is expected.

No marine hazards expected Saturday through Sunday night. Winds
light and variable through the period.

&&

.TIDES/COASTAL FLOODING...
A Nor`easter will continue to circulate offshore through
Thursday as high pressure builds to our north. This will lead to
persistent northerly flow over the waters. Minor flooding is
expected at many tidal sites tonight through the day Thursday,
but some uncertainty still remains.

&&

.LWX WATCHES/WARNINGS/ADVISORIES...

MD...Small Craft Advisory until 6 PM EDT this evening for MDZ008.
