Areas affected...Portions of central Illinois into far western
Indiana

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

Valid 021448Z - 021645Z

Probability of Watch Issuance...20 percent

SUMMARY...Currently elevated storms in central Illinois will move
eastward. Marginally severe hail and isolated damaging winds are
possible. A watch is not currently expected.

DISCUSSION...A cluster of elevated storms are moving eastward in
west-central Illinois. Steep mid-level lapse rates (observed on the
12Z ILX sounding), strong shear, and strong moisture return will
allow occasionally intensification of this activity. Marginally
severe hail as well as isolated damaging winds are possible with the
strongest storms.

Muted surface heating is occurring ahead of and south of this
activity through a thick cirrus canopy. Moisture return is also
pushing dewpoints into the low 60s F as far north as Springfield,
IL. Through time, the southern fringe of this activity may become
surface based and pose a greater severe risk. At least in the short
term, however, watch is not expected.
