AREAS AFFECTED...ERN CO/WRN KS/PARTS OF THE TX AND OK PANHANDLES
CONCERNING...SEVERE THUNDERSTORM WATCH 193...
VALID 270724Z - 270930Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 193
CONTINUES.
LATEST RADAR LOOP SHOWS THE STRONGEST ONGOING CONVECTION ACROSS SERN
CO ATTM...WITHIN A NARROW INSTABILITY AXIS INDICATED BY OBJECTIVE
ANALYSES. WITHIN THIS AXIS...SELY LOW-LEVEL FLOW CONTINUES TO
ADVECT LOW-LEVEL MOISTURE NWWD INTO THE HIGH PLAINS...BENEATH
STEEPENING MID-LEVEL LAPSE RATES ASSOCIATED WITH THE
EJECTING/NEGATIVELY-TILTED SHORT-WAVE TROUGH.
WHILE THE AXIS OF GREATEST INSTABILITY REMAINS MODEST AND
NARROW...CONTINUED MOISTENING DOWN LOW AND COOLING ALOFT COMBINED
WITH IMPRESSIVE FLOW FIELD WITH HEIGHT SUGGESTS POTENTIAL FOR
SEVERE/SUPERCELL STORMS WILL CONTINUE -- PARTICULARLY ACROSS SERN CO
AND A SMALL PORTION OF ADJACENT SWRN KS. ALONG WITH POTENTIAL FOR
DAMAGING WINDS AND HAIL...AN ISOLATED TORNADO ALSO CANNOT BE RULED
OUT ACROSS A SMALL PORTION OF SERN CO...GIVEN THE FAVORABLY STRONG
LOW-LEVEL SHEAR JUXTAPOSED WITH THE MORE MOIST/UNSTABLE AIRMASS
EXISTING IN THIS PORTION OF THE REGION.
STORMS REMAIN WELL-CONTAINED WITHIN THE WW GIVEN THE NNEWD CELL
MOTIONS. THIS COMBINED WITH A MUCH LESS FAVORABLE THERMODYNAMIC
ENVIRONMENT DOWNSTREAM ACROSS NWRN KS SUGGESTS THAT ANY AREAL WATCH
EXTENSION OR NEW WW ISSUANCE APPEARS UNNECESSARY ATTM.
