AREAS AFFECTED...E CNTRL THROUGH NERN CO

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 202225Z - 210030Z

A FEW STORMS WILL BE CAPABLE OF PRODUCING ISOLATED HAIL AND DAMAGING
WIND THROUGH MID EVENING. GIVEN THE EXPECTED ISOLATED NATURE OF THE
SEVERE THREAT...A WW IS NOT ANTICIPATED.

THIS EVENING STORMS CONTINUE DEVELOPING OVER THE HIGHER TERRAIN OF
CO INCLUDING THE FRONT RANGE W OF DENVER AS WELL AS THE PALMER
DIVIDE. OTHER STORMS ARE DEVELOPING OVER NERN CO ALONG A NE-SW
ORIENTED CONVERGENCE BOUNDARY. STRONG SURFACE HEATING AND LOW LEVEL
DEWPOINTS IN THE 50S ARE CONTRIBUTING TO STRONG INSTABILITY WITH
MLCAPE FROM AROUND 1500 J/KG NEAR THE FOOTHILLS TO NEAR 3000 J/KG
NEAR THE CO/NEB BORDER. THIS REGION IS UNDERNEATH AN UPPER RIDGE
WITH RESULTING WARM MID LEVEL TEMPERATURES...WEAK FLOW AND VERTICAL
SHEAR. WEAK VERTICAL SHEAR SUGGESTS TRANSIENT MULTICELL STRUCTURES
SHOULD REMAIN THE DOMINANT STORM TYPE. HOWEVER...THE THERMODYNAMIC
ENVIRONMENT APPEARS SUPPORTIVE OF ISOLATED DAMAGING WIND GUSTS AND
HAIL WITH THE STRONGER STORMS. ACTIVITY SHOULD BEGIN TO SUBSIDE WITH
LOSS OF HEATING.
