Areas affected...portions of northeast Missouri into west-central
Illinois

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

Valid 250113Z - 250245Z

Probability of Watch Issuance...5 percent

SUMMARY...A couple of damaging gusts may occur with a
cold-pool-driven MCS over the next few hours. A WW issuance is not
expected.

DISCUSSION...A cold-pool-driven MCS has recently organized into a
quasi-bowing structure oriented roughly normal to the 20-30 kt
effective bulk shear vectors. Surface observations suggest 10-20 F
surface temperature deficits behind the main line. Given modest
forward propagation of the MCS noted into a favorable airmass
characterized by 2500+ J/kg MLCAPE, a couple of damaging gusts
cannot be ruled out along locally stronger surges of the cold
pool/convective leading line. Nonetheless, the severe threat will be
isolated at best, so a WW issuance is not expected.
