.SYNOPSIS...
Issued at 214 AM CDT Thu May 2 2024

A warm and unsettled pattern will begin to take shape today. As a
slow moving cold front approaches and eventually stalls out,
scattered showers and thunderstorms are possible starting this
afternoon through the weekend. The unsettled pattern will continue
into mid next week as a series of fronts and shortwave troughs
move through the region.

.DISCUSSION...
(Today through Wednesday)
Issued at 214 AM CDT Thu May 2 2024

Current GOES satellite depicts a cirrus shield overspreading the
area associated with fallout from ongoing convection over the
Central and Southern Plains. As a cold front slowly approaches
from the west later this morning, showers and thunderstorms will
pick up in coverage and intensity along the decaying MCS from the
Plains. By mid to late afternoon, a few thunderstorms may still
be able to hang onto enough instability to produce a few damaging
wind gusts or perhaps some hail. Kinematics look fairly bleak (~30
kts bulk shear via the HREF), so updrafts are not expected to
have much of an organized structure.

If any storms do become strong to severe this afternoon, it would
likely be west of the Mississippi River. Despite all this cloud
cover and convection today, we still have the potential to have
our first 90 degree day of the year. NBM 90th percentile suggests
that the warmest reasonable high temperatures this afternoon are
in the low 90s for much of the area.

The aforementioned cold front is expected to stall out just to our
northwest by Friday morning. Forecast surface analyses show a
shortwave trough kicking out ahead of the front, keeping the
potential for widespread showers and thunderstorms on the table
through Friday and Saturday afternoons. Dynamics look far less
impressive through the remainder of the weekend, but expect at
least a 50% chance of rain through Sunday evening associated with
mesoscale and/or diurnal processes.

A warm front finally lifts north on Monday morning, nudging
temperatures back into the mid to upper 80s for the next several
days. In addition, southerly flow returns Monday and will allow
warm, moist Gulf Coast air to contribute to further thunderstorm
potential each day next week. The pattern looks generally
unsettled well into midweek; expect 2-3 inches of rain total over
the next 7 days.

.AVIATION...
(06Z TAFS)
Issued at 1120 PM CDT Wed May 1 2024

VFR conditions will prevail through tomorrow afternoon/evening
when an MCV moves into the Mid-South. This MCV is expected to
result in an extended period of SHRA and possible TSRA persisting
through the TAF period. Rain and thunderstorms will result in
diminished vis at all sites late tomorrow and continue through
the end of the TAF cycle. IFR are expected tomorrow night as
continuous rain and thunderstorms begin.
