.MESOSCALE UPDATE...
Issued at 940 PM CDT Sun Jun 8 2025

The forecast reasoning is generally on track for the overnight
into Monday morning concerning a convective system expected to
move across the forecast area. Considerable convective rainfall
may develop well ahead of the system in the very moist and
buoyant airmass per recent CAM guidance consensus, but any
organized severe threat continues to correlate with our latest
severe weather timing graphic for the early to mid morning hours.

.DISCUSSION...
Issued at 513 PM CDT Sun Jun 8 2025

Through Monday...

A well-organized convective complex is expected to develop overnight
as the result of the upscale growth of numerous strong to severe
storms across the Southern Plains this evening. This system will
reach its peak intensity upstream of our area and tracking eastward.
By the time it reaches our CWA, likely beginning in the predawn
hours Monday, severe weather potential will have diminished somewhat
compared to what the Moderate Risk area to our west will have likely
seen. However, the remains of this energy will still allow for a few
cells or bowing segments to produce damaging winds and some hail as
the convective complex interacts with an airmass that will be
moderately unstable (~2000-3000 SBCAPE), somewhat uncommon for the
5am-9am timeframe which typically sees the daily minimum in terms of
diurnally driven thermodynamic instability. Timing on the severe
weather appears most likely Monday morning (between 2-10AM west to
east), and given the trend in timing lately don't be surprised if
the primary window for the most intense storms ends up being closer
to between 5am and 1pm Monday. Some chance for redevelopment is
possible in the evening tomorrow should the early morning activity
clear out in time for a substantial diurnal upward temperature swing
prior to dusk. Any stronger cores with this activity will likely be
both transient and isolated, dissipating during the evening. /OAJ/86/

No changes to the long term:

Tuesday through the weekend...

Global guidance continues to show a cold front shifting southward
and stalling across the southeastern CONUS heading into Tuesday.
This front will provide some relief from the triple digit heat index
readings over much of our forecast area. This front will also keep
higher chances of showers and t-storms around for the rest of the
period/area for the afternoon hours and subsequently peter off after
sunset. /CR/OAJ/

.AVIATION...
(00Z TAFS)
Issued at 648 PM CDT Sun Jun 8 2025

VFR conditions with southwesterly breezes will be the general
rule for the forecast area through this evening, then expect MVFR
category stratus to become prevalent late tonight into Monday
morning. Short duration TS conditions, and potential +T with
damaging wind, may occur with a convective system moving from
west to east during the early to mid morning hours. In the wake of
the system, expect improving aviation weather from late morning
through afternoon. /EC/
