DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0758 PM CDT TUE OCT 25 2011
VALID 260100Z - 261200Z
...NO SVR TSTM AREAS FORECAST...
...IL...IND...WRN OH...SRN LOWER MI...
LOW PRESSURE WILL CONTINUE TO SHIFT EWD FROM NRN IL TOWARDS LAKE
ERIE BY 12Z WED. SCATTERED THUNDERSTORMS WERE ALREADY ERUPTING
WITHIN A WEAK LOW PRESSURE TROUGH EXTENDING FROM NRN IL SWWD TO THE
MS RIVER...AND THESE STORMS SHOULD PERSIST FOR SEVERAL MORE HOURS. A
MARGINALLY SEVERE HAIL AS WELL AS GUSTY WINDS MAY OCCUR WITH THESE
STORMS...WITH HAIL BECOMING THE DOMINANT THREAT OVERNIGHT AS PARCELS
BECOME ELEVATED. SEVERE COVERAGE IS EXPECTED TO BE ISOLATED. FOR
MORE INFORMATION SEE MESOSCALE DISCUSSION 2272.
...SERN KS/NERN OK INTO SWRN MO...
REMOVED LOW END HAIL PROBS DUE TO EXPECTED VERY WEAK INSTABILITY.
WHILE ISOLATED THUNDERSTORMS MAY OCCUR LATER TONIGHT...PARAMETERS IN
PLACE DO NOT APPEAR TO FAVOR ANY TYPE OF SEVERE WEATHER. A RATHER
MEAGER MOIST LAYER AS DEPICTED BY FORECAST SOUNDINGS FURTHER
SUGGESTS THAT STRONG CONVECTION MAY NOT EVEN OCCUR.
