(Rest of today through Friday)
Issued at 1157 AM CDT Thu Apr 18 2024
We started off cloudy this morning, but the clouds have been
breaking up and we expect temps to take off into the low to mid
80s this afternoon. As temps warm, the atmosphere will destabilize
with capes rising to 1000-2000 J/kg by late afternoon. This will
set the stage for development of showers and thunderstorms.
The first storms will form late this afternoon and evening as
an impulse moves northeast from the Southern Ms Valley. This
impulse will bring a first round of scattered thunderstorms
starting as early as 3 PM in our western counties, with storms
peaking in coverage and intensity from 7 PM to 10 PM. Later this
evening, another batch of thunderstorms in the form of a
weakening QLCS will come from the west ahead of a cold front.
Each of these rounds of storms has the potential to produce severe
wx, although latest models are not very impressive bringing shear
and instability together. Generally, the greatest thunderstorm
coverage and severe potential will exist west of I-65. It looks
like the first batch will arrive with fairly strong cape but weak
to marginal deep layer shear. A handful of warnings may bee issued
for localized wind gusts over 60 mph and severe hail over 1 inch
in diameter. Later in the evening, the instability wanes, but
shear values will become higher as the QLCS approaches. Damaging
wind gusts of 60 mph appear to be the main concern for late
evening and overnight, but a tornado cannot be ruled out for our
far northwest counties. The incoming band of storms may fall apart
pretty quickly while encountering mediocre lapse rates and more
stable surface air, possibly already worked over by early evening
storms.
Otherwise, a few spots may have some brief street flooding with
any heavy downpours this evening. We don't expect widespread
flooding problems.
Showers and few leftover storms will move out Friday morning. We
will be left with mostly cloudy and cooler conditions as a north
breeze drops temps back to normal or a little cooler than normal.
