...CONTINUED HOT AND HUMID WITH SCATTERED STORMS...

.UPDATE...
High Pressure ridge axis responsible for the widespread heat and
humidity continues to slowly flatten and drift southward today.
This combined with a few high clouds will take just a slight edge
off the temps this afternoon, but overall still expect Highs in
the lower to middle 90s across NE FL and middle to upper 90s
across SE GA and still combined with the humidity expect heat
indices/"feels-like" values still peaking around 105 degrees early
to mid afternoon hours. Morning soundings showing just a slight
nudge downward in Precipitable Water Amounts (PWATs) into the 1.8"
to 2.0" range along with some slight warming at 500mb to around -6C.
This all leads to slightly less storm coverage to 40-50% this
afternoon and early evening and with ridge axis weakening even
slower storm motion around 5 mph or less as sea breeze fronts push
even slower inland and storm mergers/outflows taking over through
the rest of the afternoon and evening. Isolated strong to severe
storms with 40-60 mph winds still possible in local wet microburst
potential in the most intense storms. The usual decrease in storm
activity after sunset with the all-clear around midnight. The
slight increase in westerly flow aloft across SE GA will push a
few of the storms all the way to the beaches, while storms along
the East Coast Sea Breeze in NE FL should just stay inland from
the coast and drift slowly Southwest through the rest of the day.

&&

.AVIATION...
Mainly VFR conds this morning with a few high clouds, otherwise
deep moisture in place will continue a chance for storms at the
TAF sites once again today, just a bit later than y'day with
timing mainly in the 19-22z time frame with TEMPO gusty winds to
25 knots and potential IFR VSBYS and MVFR CIGS. Again becoming
VFR after 00z as storms fade again after sunset.

&&

.MARINE...
High Pressure Ridge Axis across the waters will continue south
winds through tonight at 10-15 knots with seas 1-3 ft. Just enough
upwelling to continue to drop SAUF1 (St Augustine Pier) water
temps down into the upper 70s during the morning hours. Storms
will develop once again right at the sea breeze along the coast
and will mainly stay inland along NE FL coast, but may push into
the nearshore SE GA waters with some light westerly winds aloft.
