Day 3 Convective Outlook

0220 AM CST Sun Mar 01 2026

Valid 031200Z - 041200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Isolated to scattered thunderstorms will be possible from Tuesday
into Tuesday night from parts of the southern and central Plains
eastward into the mid Mississippi Valley. Isolated storms may also
develop in south Florida.

...Southern and Central Plains/Mid Mississippi Valley...
At mid-levels, a shortwave ridge will move eastward into the Ozarks
on Tuesday, as flow becomes southwesterly over the south-central
U.S. Further west, an upper-level trough will move through the Four
Corners region. At the surface, a moist airmass with surface
dewpoints in the 50s and 60s F will advect northward across the
southern Plains and Arklatex. A cold front will move southeastward
into the central Plains. To the south of the front, an axis of
instability is forecast to develop in the afternoon from northwest
Texas into southeast Kansas and the northern Ozarks. The airmass is
expected to be capped across much of Texas and Oklahoma, although an
elevated storm or two will be possible Tuesday night. The greatest
chance for storms will be from eastern Kansas into the northern
Ozarks, where convective development will be aided by lift
associated with the exit region of a 40 to 50 knot low-level jet.
Considerable variance exists among the model solutions concerning
instability, suggesting that any severe threat will be highly
conditional. If moisture return ends up being greater than is
currently forecast, a marginal severe threat may need to be added in
later outlooks.

Valid 021200Z - 031200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorms will be possible on Monday and Monday night across
parts of the central U.S. and from the Intermountain West into the
central Rockies.

...Synopsis...
A broad fetch of isentropic ascent will likely become established
across the central U.S. Monday through Monday night as
south/southwesterly 925-850 mb winds gradually increase in response
to the approach of an upper wave from the West. While buoyancy
profiles will likely be fairly modest due to poor mid-level lapse
rates, adequate low-level moistening should take place to support
isolated elevated thunderstorms from the southern Plains northward
into the mid-MS River Valley. Although surface-based buoyancy should
be maximized across western TX in proximity to a meandering dry
line/lee trough and south of a weak front, very warm temperatures at
850 mb/strong capping will subdue convective potential. Across the
Intermountain West, cold temperatures aloft associated with the
upper wave should support isolated lightning flashes.
