Areas affected...southeast Missouri into southern Illinois...western
Kentucky and Tennessee

Concerning...Severe potential...Watch possible

Valid 190441Z - 190645Z

Probability of Watch Issuance...60 percent

SUMMARY...Scattered storms are likely to persist through the early
morning hours, and some may produce damaging hail.

DISCUSSION...Southwest winds of 20-25 kt at 850 mb are aiding
theta-e advection into the region, in the wake of the earlier MCSs.
Storms have already formed over the MO/IL/KY border area, with signs
of incipient development to the northwest into central/eastern MO.
Although the storms are elevated in nature, substantial instability
is present to support strong updrafts, and shear is favorable in the
cloud-bearing layer due to 50 kt mid and high-level winds. As such,
at least isolated severe storms capable of hail are anticipated,
from MO into TN, for a several hour period. If too many storms form
in this zone, storm mode could conceivably interfere destructively
and reduce hail potential.
