Areas affected...eastern Oklahoma...northern Arkansas...and southern-east-central Missouri

Concerning...Severe potential...Watch unlikely=20

Valid 042053Z - 042230Z

Probability of Watch Issuance...20 percent

SUMMARY...Scattered strong thunderstorms are possible this afternoon
and evening from eastern Oklahoma across northern Arkansas and into
Misosuri.

DISCUSSION...Scattered thunderstorms have developed along and ahead
of a cold front from eastern Oklahoma into northwest Arkansas and
into Missouri. The airmass ahead of this cold front is moderately
unstable with MLCAPE around 1500 to 2000 J/kg. Effective shear is
relatively weak (<30 knots per SPC mesoanalysis), but VWPs closer to
the cold front (INX and SGF) are sampling greater 0-6 km shear
between 25 and 30 knots. This, in addition to low-level convergence,
will support more robust updrafts near the cold front. A few strong
to isolated severe storms will be possible this afternoon. However,
height rises and broad synoptic scale subsidence should preclude a=20
more organized severe weather threat and the need for a watch.
