.DISCUSSION...
Issued at 420 AM CDT Tue Jun 18 2024

Today and Tonight...High pressure at both the surface and aloft,
centered east of the region, will build west and into the forecast
area over the next 24 hours.  This will result in easterly to
southeasterly flow across the CWA, which in turn will begin bringing
in a slightly drier airmass.  This will also cause less coverage of
showers and storms this afternoon and evening, by forcing the best
rain chances over western portions of the area.

Skies today will remain mostly cloudy, but a few peaks of sun will
be seen across the area through the course of the day.  Highs will
range from the lower 80s to around 90.  For tonight, clouds will
remain a staple across the area as lows fall into the low and middle
70s. /19/

Wednesday Through This Weekend: The rather strong 595 dam mid level
ridge will have expanded from its origin over the mid-atlantic
states across much of the Mid MS Valley. This will result in strong
southerly wind flow that will keep moisture constant with rain and
storm chances through mid-week. These rain and storm chances will
mainly be focused along our southern counties and the highest rain
totals will be along the coast nearer to the tropical airmass coming
from the Gulf of Mexico.

Thursday-Monday: Ridging at the surface and aloft will help mitigate
rain chances as the more moist tropical airmass will be in place
further west southwest as the disturbance/depression continues its
track west through Mexico. Through the longterm period we can expect
to see seasonably warm temps with mid 90s high temperatures expected
through late week. It is also worth noting there will also be a
chance for triple digit temps as we transition into the
weekend./KP/

.AVIATION...
(06Z TAFS)
Issued at 1231 AM CDT Tue Jun 18 2024

High clouds as a result of this afternoon`s convection will
plague the area through much of the overnight hours. Some
scattered low clouds, and potentially some patchy fog, are
possible across mainly Southeast Mississippi around day break.
This could cause flight categories to briefly fall to MVFR/IFR
status between mainly 09-13Z. Both ceilings and any reduced
visibility will quickly begin improving after sunrise. VFR flight
categories will then prevail at all area TAF sites through the
remainder of the forecast period. Winds will be calm to light from
the east overnight, increasing to between 8-10 knots by late
morning, with a few gusts reaching to around 20 knots possible at
times. /19/
