.DISCUSSION...
(Today through Tuesday)
Issued at 241 AM CDT Wed May 14 2025

A calm night can be found across the region at this hour as upper
level ridging builds in from the west. This ridging will return
mostly dry conditions and allow temperatures to soar into the upper
80s today and tomorrow. Some areas could see their first 90
degree day of the year today. Probabilities of exceeding 90 on
Thursday are a bit higher as the ridge centers over the Mid-
South. Southerly winds increase today allowing for plenty of Gulf
moisture transport to increase dewpoints into the 60s and 70s.

With ample moisture and hot conditions, this brings an increased
focus on severe weather chances as a negatively tilted trough
traverses across the Central Plains. The greatest height falls
remain well north of the Mid-South. Guidance however does show a
decent QPF signal, hinting at organized convection. Confidence is
low at this time for anything more than a marginal severe threat
on Thursday night into Friday morning. If this threat does
materialize, the at risk areas would be confined to areas north of
I- 40.

Friday does have more favorable kinematics for severe weather, but
soundings are showing a stout EML. This EML looks to set in the core
of the upper level jet with very little height falls until after the
primed environment has settled some. Instability has continued to
trend downwards (down to 1500 J/kg from near 4000 J/kg) with this
activity, but lapse rates remain very steep (nearing 8 C/km). If
guidance continues to hold onto the deep EML, the best severe
weather window may occur along the warm front surging back north
Friday night. This would promote large hail as a primary threat. As
diurnal trends takeover after sunset, the LLJ will intensify and
transition to a damaging wind threat with around 60 kts of effective
shear.

Hot and humid conditions will continue with temperatures in the 80s
and continuing to near 90 degrees into early next week. Another
storm complex will take aim from the Southern Plains to keep an
unsettled weather pattern in affect. As a summer-like regime,
instability will not be hard to come by resulting in thunder storm
chances through at least early next week.

Issued at 1206 PM CDT Wed May 14 2025

A brief period of MVFR ceilings is expected this afternoon across
northern sections of the Mid-South. Otherwise, VFR conditions will
be found for much of the forecast period. Winds will remain from
the south at 10 to 15 knots with higher gusts. Low-level wind
shear could occur overnight across western and southern sections
of the region.
