.DISCUSSION...
KEY MESSAGE 1: Above seasonal temperatures and rain-free
conditions will prevail throughout the week. A cold front will
bring cooler temperatures this weekend.

With the remnants of Isaias well away from the region, high
pressure will continue to build into the area yielding drier and
warmer conditions throughout the week. There`s some concern for
near record high temperatures a couple days this week (see
Climate section below). Expect temperatures to range in the mid
to upper 80s through the end of the work week, before dropping
into upper 60s and low 70s this weekend after a cold front
passes through on Friday night. This will bring significantly
cooler conditions to region this weekend compared to previous
several days.

&&

.AVIATION /12Z MONDAY THROUGH FRIDAY/...
VFR conditions will prevail at KCHS, KJZI, and KSAV through 12z
Tuesday.

Extended Aviation Outlook: VFR.

&&

.MARINE...
Today and tonight: Offshore west-northwest flow will start off
in the 15-20 knot range this morning and will then steadily
diminish through the evening. Overnight, winds will turn more
northerly and mostly stay in the 5-10 knot range. Seas will
steadily diminish through the period, becoming 2-3 feet
overnight.

Tuesday through Friday: Overall, quiet conditions are expected
across the local waters with winds and seas remaining below
Small Craft Advisory thresholds through the week. High pressure
will be the dominant weather feature across the region, and wind
speeds will mostly stay below 10 knots. Seas should remain in
the 2-3 ft range through the week.
