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

   Concerning...Severe potential...Watch unlikely 

   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.
