LizardMafia Posted July 19, 2012 Share Posted July 19, 2012 MESOSCALE DISCUSSION 1502 NWS STORM PREDICTION CENTER NORMAN OK 0227 PM CDT THU JUL 19 2012 AREAS AFFECTED...PARTS OF E CNTRL IL INTO CNTRL IND CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE VALID 191927Z - 192100Z PROBABILITY OF WATCH ISSUANCE...60 PERCENT SUMMARY...TRENDS ARE BEING MONITORED FOR AN INCREASING SEVERE WEATHER THREAT THAT COULD REQUIRE A WATCH AS EARLY AS 21-22Z. DISCUSSION...SIGNIFICANT DESTABILIZATION IS ONGOING NEAR A SURFACE LOW...NOW CENTERED NORTH OF CHAMPAIGN...AND DEVELOPING SOUTHEASTWARD TOWARD THE INDIANAPOLIS AREA. LOW-LEVEL LAPSE RATES ARE BECOMING RATHER STEEP WITH CONTINUED HEATING...AND OBJECTIVE ANALYSES INDICATE THAT CAPE FOR THE MOIST BOUNDARY LAYER IS INCREASING IN EXCESS OF 2000 J/KG. DEEP LAYER NORTHWESTERLY MEAN FLOW IS GENERALLY WEAK TO MODEST IN STRENGTH...ON THE ORDER OF 20-30 KT...BUT VERTICAL SHEAR MAY BE MARGINALLY SUFFICIENT TO ENHANCE POTENTIAL CONVECTIVE ORGANIZATION...AND PERHAPS SUPPORT AT LEAST SHORT-LIVED UPDRAFT ROTATION. COUPLED WITH THE THERMODYNAMIC PROFILES...THE ENVIRONMENT IS EXPECTED TO CONTINUE BECOMING INCREASINGLY CONDUCIVE TO SEVERE STORMS. A BRIEF TORNADO MAY NOT BE OUT OF THE QUESTION...BUT THE RISK FOR DAMAGING WIND GUSTS APPEARS MORE PROMINENT...ALONG WITH SOME HAIL. INHIBITION MAY WEAKEN SUFFICIENTLY FOR STORM DEVELOPMENT WITHIN THE NEXT COUPLE OF HOURS...WHICH SHOULD TEND TO SPREAD EAST SOUTHEASTWARD NEAR A WARM FRONT/REMNANT OUTFLOW BOUNDARY ACROSS CENTRAL INDIANA LATE THIS AFTERNOON.
