.DISCUSSION...
KEY MESSAGE 1: High temperatures will be slightly above normal
on Tuesday, then gradually rising through the holiday weekend.
Heat Advisories could be needed during the holiday weekend
across portions of our area.

Ridging aloft will remain the dominant synoptic feature this week,
initially centered over the TN Valley on Tuesday. It will then shift
eastward towards the East Coast by the end of the week and remain in
place through the holiday weekend. The main forecast highlight will
continue to be the temperatures. Wednesday will feature highs
slightly above normal, with temperatures warming to above normal
into the holiday weekend. High temperatures could again reach into
the mid to upper 90s late week and into the holiday weekend, which
combined with dewpoint values in the 70s will likely yield heat
index values in the 100-110 range. Heat Advisories could be required
for portions of the forecast area at the end of the week and into
the holiday weekend. Generally a dry forecast has been maintained,
with PoPs trending upwards towards a more typical summertime
pattern in the later half of the holiday weekend.

.AVIATION /01Z TUESDAY THROUGH SATURDAY/...
VFR conditions are expected to prevail at CHS/JZI/SAV terminals
through 00Z Wednesday. Winds will become light from the
northeast overnight, then become more directly east Tuesday
morning and afternoon, possibly gusting upwards to 15-20 kt
during peak heating hours. A few showers and/or thunderstorms
could impact the SAV during the afternoon, but confidence
remains too low to mention in the latest TAF issuance.

Extended Aviation Outlook: VFR conditions are anticipated at
CHS/JZI/SAV terminals through late week.

&&

.MARINE...
This Evening and Overnight: East/southeast winds around 10 kt or
less this evening will shift to northeast and slightly surge to
10-15 kt overnight well behind a boundary/weak front departing
south of local waters. Seas will generally range between 2-3 ft,
possibly building a foot approaching daybreak Tuesday (largest
beyond 20 nm from the coast).

Extended Marine: The synoptic pattern will generally support
winds from the NE or E through Thursday. Then, they will clock
around to the SW by Friday morning. Friday into the holiday
weekend, winds will have a typical summertime pattern. This will
consist of some backing during the day, with the highest winds
along the land/sea interface with the formation of the sea
breeze. Gusts could approach 20 kt, especially in Charleston
Harbor as the sea breeze moves through. At night, expect winds
to veer and possibly ease a few kt. Seas should stay 5 ft or
less. No Small Craft Advisories are expected.
