MESOSCALE DISCUSSION 1848
NWS STORM PREDICTION CENTER NORMAN OK
0110 PM CDT WED JUL 30 2025
AREAS AFFECTED...COLORADO FRONT RANGE
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 301810Z - 302015Z
PROBABILITY OF WATCH ISSUANCE...5 PERCENT
SUMMARY...SCATTERED THUNDERSTORMS CAPABLE OF ISOLATED OCCURRENCES OF
SEVERE HAIL OR SEVERE WIND GUSTS WILL BE POSSIBLE THIS AFTERNOON
ACROSS THE COLORADO FRONT RANGE INTO PORTIONS OF THE EASTERN
COLORADO PLAINS. GIVEN THE LOCALIZED NATURE OF ANY SEVERE THREAT,
WEATHER WATCH ISSUANCE IS NOT EXPECTED AT THIS TIME.
DISCUSSION...DAYTIME HEATING AND BOUNDARY-LAYER MIXING OVER THE
CENTRAL AND FRONT RANGE OF THE ROCKY MOUNTAINS HAS RESULTED IN
WIDESPREAD THUNDERSTORM DEVELOPMENT THAT IS EXPECTED TO CONTINUE AND
PERSIST INTO EASTERN COLORADO. WITH MOST UNSTABLE CAPE ONLY REACHING
500-1000 J/KG AND A RELATIVE DEARTH OF DEEP-LAYER VERTICAL SHEAR,
THERE IS NOT MUCH ENVIRONMENTAL SUPPORT FOR WIDESPREAD ORGANIZED
SEVERE CONVECTION. HOWEVER, WITH FREEZING LEVELS NEAR THE
SURFACE-BASED PARCEL LFC HEIGHTS, AND INVERTED-V BOUNDARY LAYER
PROFILES EVIDENT IN PROXIMITY SOUNDINGS, SOME ISOLATED INCIDENTS OF
<= 1.25 IN HAIL AND SEVERE WIND GUSTS (LARGELY <= 60 MPH) ARE
POSSIBLE. SOME LOCALLY HIGHER WIND GUSTS COULD OCCUR IF ANY
CONVECTION DEVELOPS LEADING-EDGE OUTFLOW OR SHOWS SIGNS OF TRANSIENT
ORGANIZATION INTO LINEAR CLUSTERS.
