  affect the forecast area through Saturday.

.DISCUSSION...
Issued at 245 PM CDT Wed Apr 2 2025

18z KLZK upper air observation indicates a `loaded gun` type
sounding. MUCape of > 4000kg is indicated, with a 0-3km (supercell
discriminator) of > 275 m2/s2.

After convective inhibition erodes this afternoon, all parameters
derived from this sounding support supercell development, with
support for long track, significant or greater tornadoes. Several
brief supercells already have been noted this afternoon.  Near
term forecasts will occupied on this severe weather event, which
will last throughout the evening hours, as a cold front moves
east into the forecast area.

This cold frontal boundary that will focus this severe weather event
will stall across the forecast area on Thursday. This feature
will become nearly stationary, as it becomes parallel to the
southwesterly upper level flow. The front will likely wobble due
to convective outflow(s), but much of the area will receive
excessive rainfall through Saturday, as several waves in the
southwest flow interacts with the boundary. The rainfall will
produce not only a flash flooding threat, but a river flooding
threat as well.

Rainfall will finally come to an end late Saturday and early Sunday.

Near to below normal temperatures will prevail Sunday through
Wednesday.

(06Z TAFS)
Issued at 1214 AM CDT Thu Apr 3 2025

Expect light and variable surface winds to begin the forecast period
across all sites. CIGS and VSBY will degrade to as low as by late
Thursday morning as the cloud deck will lower to MVFR and eventually
IFR conditions as a boundary is expected to stall across Arkansas.
Additionally, expect showers and thunderstorms over the majority of
the forecast period across all sites. Surface winds will gust in
excess of 24 knots across all terminals by late Thursday morning
before losing their gusting condition late Thursday evening.
