Areas affected...Parts of central IL

Concerning...Severe Thunderstorm Watch 39...40...

Valid 141035Z - 141200Z

The severe weather threat for Severe Thunderstorm Watch 39, 40
continues.

SUMMARY...Localized strong/damaging gusts remain possible this
morning.

DISCUSSION...A small MCS is moving across western IL early this
morning, with recent reports of severe gusts in McDonough County. An
embedded mesovortex recently developed in Knox County, IL, in
relatively close proximity to an outflow boundary and also the
synoptic warm front. MUCAPE of 1000-1500 J/kg (greater with southern
extent) and strong deep-layer shear (as noted on the KILX VWP) will
continue to support organized convection through the early morning.
While the northern part of the MCS and related MCV will continue
moving into a relatively cool/stable environment across northern IL,
some short-term threat for localized strong/damaging gusts may
persist, especially near/south of the warm front. Stronger updrafts
along the leading edge of the cold pool could also pose a transient
hail threat. Finally, a brief tornado cannot be ruled out near the
intersection of the leading outflow and warm front, though lingering
low-level stability may temper this threat to some extent.
