Areas affected...Northern IL...Far Southern WI

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

Valid 261230Z - 261400Z

Probability of Watch Issuance...20 percent

SUMMARY...Isolated hail is possible across northern IL and far
southern WI this morning.

DISCUSSION...Thunderstorm intensity has increased within the cluster
of warm-air advection storms in the western WI/IL border vicinity.
These storms are in between a southward-surging outflow moving
across southern WI and a somewhat diffuse warm front extending from
CWI to IKK. 12Z DVN sounding sampled an airmass supporting strong
elevated thunderstorms capable of isolated hail. Additionally, the
air mass downstream should further destabilize amid filtered heating
and modest low-level moisture advection. As such, a few instances of
hail are possible this morning as the cluster moves into
north-central and northeast IL. Some additional thunderstorm
development is possible farther south as well. Overall severe
coverage will likely remain isolated, and a watch is unlikely in the
near term. However, convective trends will be monitored closely for
signs of a more widespread severe potential.
