Areas affected...east-central IN...west-central OH

Concerning...Severe potential...Watch unlikely 

Valid 260129Z - 260200Z

Probability of Watch Issuance...5 percent

SUMMARY...A zone of ambient low-level vorticity co-located with a
wind profile showing an enlarged hodograph may continue to pose a
severe risk.  A few supercells will be capable of isolated damaging
gusts and perhaps a weak/brief tornado or two during the next 30-60
minutes.

DISCUSSION...Radar imagery shows a couple of mini supercells near
the IN/OH border on the north-end of a broken squall line over the
Miami Valley in southwest OH.  Despite relatively cool surface
conditions (low-mid 60s temperatures), a saturated profile in the
low levels is contributing to 250 J/kg MLCAPE.  The 00z ILN raob
showed some enlargement in the hodograph (200 m2/s2 0-1 km SRH). 
Expecting the low-level mesocyclone potential and associated hazards
to gradually become more confined both temporally and spatially
during the next hour.  Until then, a localized damaging wind and
tornado risk may accompany the strongest circulations.
