AREAS AFFECTED...SWRN KS / FAR SERN CO
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 021835Z - 021930Z
POTENTIAL APPEARS TO BE INCREASING FOR AN ISOLD BRIEF TORNADO OR TWO
ACROSS PARTS OF FAR SERN CO AND SWRN KS.
COMPACT AND NEARLY VERTICALLY STACKED LOW/COLD POCKET OVER SWRN KS
WILL ONLY SLOWLY DRIFT EWD OVER THE NEXT FEW HOURS. SURFACE
ANALYSIS SHOWS A MOIST AXIS CHARACTERIZED BY UPPER 50S DEWPOINTS
EXTENDING WWD FROM S-CNTRL KS TO SERN CO. WITHIN THIS
CORRIDOR...SEVERAL SMALL CB/S HAVE REPORTEDLY PRODUCED FUNNEL CLOUDS
OVER BACA COUNTY WITHIN THE PAST HOUR. LATEST VISIBLE IMAGERY SHOWS
WIDESPREAD BUT BROKEN CLOUD COVER MAINLY OVER PARTS OF SWRN KS.
STUNTED BUT SUFFICIENT DIABATIC HEATING HAS LEAD TO A MARGINALLY
UNSTABLE AIRMASS /250-750 J/KG MLCAPE/ WITHIN A SHELTERED LOW LCL
ENVIRONMENT /AOB 1000 M/. STRONGLY VEERING WIND PROFILES IN EXIT
REGION OF UPPER JETLET MAY SUPPORT TRANSIENT SUPERCELL STRUCTURE
WITH TIME IF STORMS CAN ORGANIZE. LARGE LOW LEVEL CAPE AMIDST
ABUNDANT LOW LEVEL VORTICITY /PER STRONGLY VEERED PROFILES/ IN
BACKED SURFACE FLOW MAY CONTINUE TO SUPPORT FUNNEL CLOUDS AND
PERHAPS A BRIEF TORNADO OR TWO. GIVEN LIMITED AREAL EXTENT AND
NATURE OF THREAT...A WW IS NOT ANTICIPATED ATTM.
