.SHORT TERM...
(Today through Tuesday)
Issued at 339 AM CDT Mon Aug 12 2024

High pressure moves east to be positioned more directly over the top
of us.  This adds a degree or two to our high temps and, more
significantly, allows some Gulf moisture into the area.  PW end up
around 2.0 today and increase to 2.1ish tomorrow.  Because the high
is directly over us, winds are even lighter than the past couple
days.  Apparent Temperatures push up against the limit for a heat
advisory, but aren`t quite there...yet. The high pressure will
continue to force lower rain chances, but there are enough
temperature differentials to develop some sea/lake breeze boundaries
that may generate enough lift to kick off some convection.  Nothing
severe is expected, but there could be lightning and gusty winds
associated with any pop-up storm that does happen to form.

.LONG TERM...
(Tuesday night through Sunday)
Issued at 339 AM CDT Mon Aug 12 2024

Wednesday through the end of the period sees continued high pressure
dominance in our area, but a slight change to the synoptic pattern
sees the possibility of a trough digging in just to our east.  True
impact of this pattern is not high, but is enough to increase rain
chances slightly due to higher moisture availability as well as
increased Apparent Temperature to trigger the need for Heat Advisory
headlines.  Any rain that occurs could be accompanied by lightning
and gusty winds. /Schlotz/

.AVIATION...
(06Z TAFS)
Issued at 1137 PM CDT Sun Aug 11 2024

Overall no real issues. All terminals currently in VFR and likely
to remain that way for much if not all of the forecast. The only
slight concern would be a rogue storm or two that develops in the
afternoon along the lake breeze and/or sea breeze. /CAB/

.MARINE...
Issued at 339 AM CDT Mon Aug 12 2024

The dominant high pressure remains in place continuing the light
winds and seas. Isolated to scattered showers will be possible
daily primarily in the early morning, which could have lighting
and gusty 30-40mph winds.
