MESOSCALE DISCUSSION 0713
NWS STORM PREDICTION CENTER NORMAN OK
0821 PM CDT SUN MAY 19 2013
AREAS AFFECTED...CNTRL AND SRN MN INTO NRN IA
CONCERNING...TORNADO WATCH 180...
VALID 200121Z - 200215Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 180 CONTINUES.
SUMMARY...THE THREAT FOR ORGANIZED SEVERE WEATHER IS EXPECTED TO
DIMINISH ACROSS REMAINING VALID PARTS OF WATCH AREA. AS SUCH...THE
WATCH CAN BE ALLOWED TO EXPIRE AT 02Z.
DISCUSSION...THE 00Z MPX SOUNDING INDICATES THAT CONSIDERABLE
CONVECTIVE OVERTURNING HAS OCCURRED WITH THE EARLIER PASSAGE OF
SEVERE STORMS. MOREOVER...REGION IS LIKELY IN A ZONE OF SUBSIDENCE
IN THE WAKE OF AN MCV PROGRESSING NWD INTO N-CNTRL MN. AS
SUCH...THE REMAINING VALID PORTION OF THE WATCH CAN BE ALLOWED TO
EXPIRE AT 02Z.

MD 0712 CONCERNING TORNADO WATCH 181... FOR ERN - NERN - AND N-CNTRL KS / SERN NEB / NWRN MO
MESOSCALE DISCUSSION 0712
NWS STORM PREDICTION CENTER NORMAN OK
0755 PM CDT SUN MAY 19 2013
AREAS AFFECTED...ERN - NERN - AND N-CNTRL KS / SERN NEB / NWRN MO
CONCERNING...TORNADO WATCH 181...
VALID 200055Z - 200200Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 181 CONTINUES.
SUMMARY...THE TORNADO THREAT IS SEEMINGLY CONFINED TO THE QLCS ALONG
THE KS/MO BORDER AND OVER SERN KS.
DISCUSSION...SUBJECTIVE SURFACE MESOANALYSIS SHOWS MUCH OF N-CNTRL
AND NERN KS IN A RAIN-COOLED/PARTIAL CONVECTIVELY OVERTURNED AIRMASS
WITH TEMPS IN THE 60S/LOWER 70S. SOME VIGOR HAS BEEN NOTED ON THE
WRN EDGE OF THE TORNADO WATCH OVER N-CNTRL KS WHERE UPSTREAM
MID-LEVEL LAPSE RATES ARE STILL SUPPORTIVE FOR PERHAPS A LOCALLY
STRONG WIND GUST/MARGINALLY SEVERE HAIL THREAT.
FARTHER E ALONG THE KS/MO BORDER...A QLCS CONTINUES MOVING NEWD
ACROSS PORTIONS OF THE LOWER MO VALLEY. KEAX RADAR IMAGERY SHOWS
ENHANCED POCKETS OF SEVERE WIND GUSTS IN ASSOCIATION WITH THE QLCS
PASSAGE. ALTHOUGH THE TORNADO THREAT IS SOMEWHAT LIMITED GIVEN THE
CONVECTIVE MODE...A NON-ZERO TORNADIC MESOVORTEX THREAT IS STILL
POSSIBLE GIVEN THE STRONG LOW LEVEL SHEAR PROFILE OVER THIS REGION.
MORE CELLULAR STORMS HAVE DEVELOPED OVER S-CNTRL KS AND WILL LIKELY
CONTINUE TO INGEST A MOISTURE RICH/UNSTABLE AIRMASS FROM THE S.
STEEP LAPSE RATES WOULD SUPPORT AN ISOLD LARGE HAIL / LOCALLY
DAMAGING WIND THREAT. A TORNADO OR TWO IS STILL POSSIBLE THIS
EVENING AS THE 50 KT LLJ FOCUSES TOWARDS THIS REGION.

MD 0711 CONCERNING SEVERE POTENTIAL...WATCH LIKELY FOR CNTRL AND SRN WI INTO NRN IL
MESOSCALE DISCUSSION 0711
NWS STORM PREDICTION CENTER NORMAN OK
0746 PM CDT SUN MAY 19 2013
AREAS AFFECTED...CNTRL AND SRN WI INTO NRN IL
CONCERNING...SEVERE POTENTIAL...WATCH LIKELY
VALID 200046Z - 200145Z
PROBABILITY OF WATCH ISSUANCE...80 PERCENT
SUMMARY...AN INCREASING SEVERE WEATHER THREAT IS ANTICIPATED TO THE
EAST OF TORNADO WATCHES 180 AND 183 LATE THIS EVENING INTO TONIGHT.
THE PRIMARY HAZARDS WILL BE DAMAGING WINDS AND HAIL...THOUGH A
TORNADO OR TWO WILL BE POSSIBLE A NEW WATCH WILL LIKELY BE REQUIRED
WITHIN THE HOUR.
DISCUSSION...THE 00Z DVN AND ILX SOUNDINGS SHOWED THAT THE LOCAL
ENVIRONMENT REMAINS MODERATELY UNSTABLE THIS EVENING OWING TO STEEP
LOW TO MIDLEVEL LAPSE RATES AND A MOIST PBL WHERE LOWEST 100-MB
MEAN-MIXING RATIOS OF AROUND 13.5 G/KG WERE OBSERVED. THOUGH SFC
TEMPERATURES WILL START TO COOL...THE MOIST ENVIRONMENT COUPLED WITH
THE ABSENCE OF ANY APPRECIABLE CAP SHOULD MAINTAIN MODERATE
INSTABILITY INTO THE OVERNIGHT HOURS. AS SUCH...EXPECT ONGOING
BOWING TSTM COMPLEX OVER NWRN IL TO PERSIST...WITH ADDITIONAL STORMS
DEVELOPING ACROSS DISCUSSION AREA WITHIN THE EXIT REGION OF A 40-50
KT NOCTURNAL LOW-LEVEL WIND MAXIMUM WHERE WAA AND ISENTROPIC ASCENT
WILL BE ENHANCED. GIVEN A STEADY STRENGTHENING TO THE MID AND
UPPER-TROPOSPHERIC FLOW FIELD...THE ENVIRONMENT WILL BE SUPPORTIVE
OF EMBEDDED SUPERCELL AND BOWING STRUCTURES CAPABLE DAMAGING
WINDS...HAIL...AND PERHAPS A TORNADO OR TWO.

...THERE IS A MDT RISK OF SVR TSTMS ACROSS PARTS OF NORTHERN/EASTERN
OK AND SOUTHEAST KS INTO MO...
...THERE IS A SLGT RISK OF SVR TSTMS FROM THE CENTRAL/SOUTHERN
PLAINS TO THE MIDWEST/UPPER MS VALLEY...
...SOUTH-CENTRAL PLAINS TO MIDWEST/UPPER MS VALLEY...
A SCATTERED SUPERCELL OR TWO REMAINING CAPABLE OF A STRONG TORNADO
WILL REMAIN A DISTINCT CONCERN ESPECIALLY OVER THE NEXT FEW HOURS
/MID INTO LATE EVENING/ ACROSS EAST-CENTRAL/NORTHEAST OK...WITH
ADDITIONAL DEVELOPMENT INCLUDING SUPERCELLS ALONG A CONSOLIDATING
NORTHEAST-SOUTHWEST ORIENTED FRONTAL ZONE ACROSS KS INTO NORTHERN
OK.
MEANWHILE...TO THE NORTHEAST...MULTIPLE AMALGAMATING/UPSCALE GROWING
CLUSTERS WILL LIKELY CONTINUE TO EVOLVE ACROSS THE OZARKS/LOWER MO
VALLEY INTO THE MIDDLE/UPPER MS VALLEY. THE MOST SUBSTANTIAL UPSCALE
DEVELOPMENT/SUSTAINED LINEAR ORGANIZATION WILL LIKELY IMPACT THE
LOWER MO VALLEY/MIDDLE MS VALLEY TONIGHT...ESPECIALLY GIVEN
NOCTURNAL STRENGTHENING OF AN ALREADY MODERATELY STRONG SOUTHERLY
LOW LEVEL JET. POTENTIALLY WIDESPREAD DAMAGING WINDS WILL BE A
CONCERN ESPECIALLY ACROSS MO INTO EASTERN IA/FAR WESTERN IL...WITH A
FEW TORNADOES /POSSIBLY EVEN A STRONG ONE/ POSSIBLE IN ASSOCIATION
WITH EMBEDDED MESOVORTICES.
