MESOSCALE DISCUSSION 0719
NWS STORM PREDICTION CENTER NORMAN OK
1016 PM CDT SUN MAY 19 2013
AREAS AFFECTED...MUCH OF NRN-CNTRL-SWRN MO / FAR SERN KS
CONCERNING...TORNADO WATCH 186...
VALID 200316Z - 200415Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 186 CONTINUES.
SUMMARY...THE TRANSITION TO AN ISOLD DMGG WIND THREAT AS THE PRIMARY
HAZARD APPEARS TO BE EVOLVING ACROSS CNTRL AND NRN MO.
DISCUSSION...RADAR MOSAIC SHOWS A DECAYING SQUALL LINE FROM NERN MO
SSWWD TO 20 MI E OF SGF. FARTHER W...A FINE LINE IN REFLECTIVITY
DENOTES A GUST FRONT THAT HAS SURGED WELL AHEAD OF AN INTENSIFYING
SQUALL LINE ALONG THE KS/MO BORDER. SUBSTANTIAL CONVECTIVE
OVERTURNING HAS OCCURRED ACROSS NRN MO AND TO AN EXTENT PORTIONS OF
CNTRL MO --THEREBY LIMITING THE POSSIBILITY FOR A TORNADO IN THIS
AREA. FARTHER S OVER SWRN MO...A MODERATELY UNSTABLE AIRMASS
CONTINUES TO RESIDE ALTHOUGH CINH IS INCREASING OWING IN PART TO
DIURNAL COOLING.
THE AFOREMENTIONED CAPPING CONCERNS MAY PARTIALLY LIMIT THE SEVERE
THREAT...BUT A STRONG 50-60 KT LLJ SAMPLED BY THE KSGF/KLSX VWP/S
AND IMPLIED WAA REGIME IN PLACE...SUGGEST SOME WIND DAMAGE RISK WILL
CONTINUE OVER CNTRL-SRN MO...IN ADDITION TO A NON-ZERO TORNADO
POSSIBILITY.
