THE SEVERE WEATHER THREAT FOR TORNADO WATCH 203 CONTINUES.

SUMMARY...ONGOING TSTM ACTIVITY IS EXPECTED TO CONTINUE NEWD WITH
THE THREAT FOR VERY LARGE HAIL...DAMAGING WIND GUSTS...AND A FEW
TORNADOES CONTINUING FOR AT LEAST THE NEXT SEVERAL HOURS.

DISCUSSION...KFTG RADAR IMAGERY SHOWS A PAIR OF SUPERCELL TSTMS IN
THE VICINITY OF THE DENVER METRO WITH MRMS MESH RECENTLY ESTIMATING
HAIL SIZE APPROACHING 2 INCHES. SURFACE ENVIRONMENT IMMEDIATELY
DOWNSTREAM OF THIS CURRENT ACTIVITY IS CHARACTERIZED BY TEMPERATURES
IN THE MID 70S...DEWPOINTS IN THE UPPER 40S/LOW 50S...AND SELY WINDS
AROUND 15 KT. RECENT MESOANALYSIS ESTIMATES MLCAPE APPROACHING 1000
J PER KG. SLIGHTLY BETTER LOW-LEVEL MOISTURE EXISTS A BIT FARTHER
DOWNSTREAM /ACROSS NE CO/ WITH MESOANALYSIS ESTIMATING MLCAPE CLOSER
TO 1500 J PER KG.

IN ADDITION TO THIS FAVORABLE THERMODYNAMIC ENVIRONMENT...THE
KINEMATIC ENVIRONMENT IS EXPECTED TO REMAIN SUPPORTIVE OF SUPERCELLS
WITH SOME ADDITIONAL STRENGTHENING OF THE MID-LEVEL FLOW POSSIBLE.
SELY UPSLOPE FLOW IS EXPECTED TO PERSIST FOR AT LEAST THE NEXT
SEVERAL HOURS...CONTRIBUTING TO INCREASED SHEAR AND CONTINUED
LOW-LEVEL MOISTURE ADVECTION.

GIVEN ALL OF THESE FACTORS...THE SVR THREAT IS EXPECTED TO PERSIST
FOR AT LEAST THE NEXT SEVERAL HOURS. ALL SEVERE HAZARDS...INCLUDING
A FEW TORNADOES...ARE POSSIBLE.
