.SHORT TERM...
(Today through Wednesday)
Issued at 310 AM CDT TUE MAY 28 2024

Dry conditions expected today as high pressure build into the area
under northwesterly flow aloft. The main upper low slow shifts
through the Great Lakes region today through Wednesday with little
change in the overall synoptic pattern as we head into the middle
part of the week. Some guidance tries to bring in a weak upper
shortwave through the Mid-MS Valley during the day on Wednesday,
which could lead to some isolated showers and thunderstorms.
However, the probability is low given the ridge and drier air mass
in place. I`ve included 15-20% chance for rain/storms tomorrow
afternoon/evening in the far western counties, but otherwise most of
the area should remain rain-free.

.LONG TERM...
(Wednesday night through next Monday)
Issued at 310 AM CDT TUE MAY 28 2024

Weather conditions in the long term look to be dominated by rather
progressive upper level flow, with several shortwaves zipping
through periodically. Difference in timing/placement and strength of
individual shortwaves among the various models leads to a somewhat
low confidence forecast. Looks like one wave approaches the area on
Friday, and another on Saturday, both if which could lead to periods
of slightly enhanced POPs. Otherwise, we may be entering a more
summertime weather regime, with daily diurnal convective chances
being driven by mesoscale processes not handled well by the long
range global models.

.AVIATION...
(12Z TAFS)
Issued at 540 AM CDT TUE MAY 28 2024

LIFR conditions have developed across the far southeastern
portions of Central Alabama, mainly impacting TOI with low VIS and
low CIGs. This should improve soon after sunrise this morning, but
I`ve included a TEMPO for LIFR through 14z. After 14-15z,
conditions should improve at TOI, leading to VFR conditions
for all sites through the remainder of the period. We`ll likely
have a diurnal wind pattern with winds increasing during the
daytime hours before becoming light and variable near or after
00-02z.

.FIRE WEATHER...

Dry conditions expected today and tomorrow with Min RHs dropping
into the mid to upper 30% range. Northwesterly winds could be gusty
at times this afternoon before becoming light and variable during
the overnight periods. Moisture gradually increases as we go into
Thursday.
