0447 PM CDT TUE SEP 16 2025
AREAS AFFECTED...PORTIONS OF FAR SOUTHEAST COLORADO INTO FAR
SOUTHWESTERN KANSAS
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 162147Z - 162315Z
PROBABILITY OF WATCH ISSUANCE...20 PERCENT
SUMMARY...A FEW INSTANCES OF SEVERE HAIL MAY ACCOMPANY THE STRONGER
STORMS THAT CAN MATURE, AND A SEVERE GUST ALSO CANNOT BE RULED OUT.
DISCUSSION...THUNDERSTORMS HAVE BEEN INCREASING IN INTENSITY ACROSS
SOUTHEASTERN CO INTO SOUTHWESTERN KS OVER THE PAST 1-2 HOURS, WITH
50+ DBZ CORES OCCASIONALLY EXCEEDING 30 KFT PER MRMS MOSAIC RADAR
IMAGERY. THESE STORMS ARE DEVELOPING AMID A STEEP MID-LEVEL LAPSE
RATE ENVIRONMENT (E.G. 8 C/KM), YIELDING 1500-2500 J/KG MLCAPE.
DESPITE FAVORABLE BUOYANCY, VERTICAL WIND SHEAR IS RELATIVELY POOR,
AND FORCING FOR ASCENT SHOULD REMAIN WEAK AS WELL, WHICH SHOULD
LIMIT THE OVERALL SEVERE THREAT. NONETHELESS, GIVEN STEEP MID-LEVEL
LAPSE RATES, ANY STORM THAT CAN MATURE AND ACHIEVE AT LEAST
TRANSIENT SUPERCELL STRUCTURE MAY PRODUCE ISOLATED INSTANCES OF
SEVERE HAIL AND PERHAPS A SEVERE GUST OR TWO.
