.DISCUSSION...

Today through Tuesday...

Deep layer high pressure centered to our west will remain the
dominant influence on our weather once again today. The low-level
synoptic wind flow will remain weak enough for both sea breezes
to develop and move inland, bringing a focus for showers and
thunderstorms to mainly the interior and western portions of the
east coast metro areas. Mid-level temperatures remain on the cool
side of climatology and indications are that a few stronger storms
will be possible again today. Frequent lightning, small hail, and
gusty winds will be possible with the stronger storms.

Hot temperatures remain the main story over the next few days, as
highs climb into the mid to upper 90s away from the coasts. This
will send heat index values soaring up above 100 degrees by late
morning, with many areas remaining in the 100-106 degree range
through the afternoon. It appears that Collier and Mainland Monroe
Counties should again reach Heat Advisory criteria of 108 degrees
for two hours or more, so an advisory is in effect for these areas
today. Regardless of whether or not your area is in an advisory, be
sure to slow down and take breaks if you`re spending time outdoors.

Wednesday and beyond...

The deep layer ridge gradually retrogrades away from Florida
allowing the steering flow to become more easterly with time. This
will bring us back into a diurnal shower/thunderstorm cycle with
overnight/morning Atlantic showers followed by afternoon interior
and west coast thunderstorms. A deeper feed of moisture looks to
work into the area by late week in association with a trough of low
pressure suggesting we may end the week on a wetter note. Better
rain chances are likely to continue into the weekend with
temperatures trending closer to normal for this time of year.

&&

.MARINE...

Generally benign boating conditions are expected through
the period. The potential for showers and thunderstorms increases
around midweek and continues into the weekend.

&&

.AVIATION...

Generally VFR conditions are expected to prevail through the
period outside of any convection. Another round of SHRA/TSRA
expected with the seabreezes this afternoon, and at least VCTS is
expected for all terminals except KPBI.
