MESOSCALE DISCUSSION 0849
NWS STORM PREDICTION CENTER NORMAN OK
0920 PM CDT TUE MAY 28 2013
AREAS AFFECTED...NERN KS...SERN NEB...NRN MO...SRN IA
CONCERNING...TORNADO WATCH 233...
VALID 290220Z - 290315Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 233 CONTINUES.
SUMMARY...IT IS POSSIBLE THAT REMAINING VALID PORTIONS OF TORNADO
WATCH 233 MAY BE EXTENDED LOCALLY IN TIME FOR AN HOUR OR SO...BUT A
NEW WW MAY NOT BE NEEDED WITH THE SEVERE WEATHER THREAT EXPECTED TO
GRADUALLY DIMINISH WITH TIME.
DISCUSSION...LOWER/MID TROPOSPHERIC WARM ADVECTION PROBABLY WILL
MAINTAIN VIGOROUS CONVECTIVE DEVELOPMENT ACROSS THE REGION...AT
LEAST A COUPLE OF HOURS BEYOND 03Z. MID-LEVEL LAPSE RATES REMAIN
RATHER STEEP AND SUPPORTIVE OF FAVORABLE THERMODYNAMIC PROFILES FOR
A CONTINUING RISK FOR SEVERE HAIL IN STRONGEST CELLS. BUT ACTIVITY
CURRENTLY SUGGESTS LITTLE POTENTIAL FOR FURTHER ORGANIZATION AND
UPSCALE CONVECTIVE GROWTH...WITH CONDITIONS EXPECTED TO GRADUALLY
CONTINUE TO BECOME EVEN LESS FAVORABLE LATER THIS EVENING INTO THE
OVERNIGHT HOURS.
