...NO SVR TSTM AREAS FORECAST...

...SUMMARY...
THUNDERSTORMS WILL BE POSSIBLE ACROSS THE ROCKIES AND THE COASTAL
SOUTHEAST STATES AND GULF COAST REGION ON MONDAY. SOME OF THE
THUNDERSTORMS ACROSS EASTERN COLORADO AND THE ADJACENT CENTRAL HIGH
PLAINS COULD BE STRONG MONDAY AFTERNOON AND EVENING.

...SYNOPSIS...
A MODESTLY PROGRESSIVE BELT OF WESTERLIES WILL EXIST OVER THE CONUS
ON MONDAY. WITHIN THIS REGIME...AN UPPER LOW WILL CONTINUE AN
EASTWARD PROGRESSION FROM THE CENTRAL ROCKIES EARLY MONDAY TO THE
NORTH-CENTRAL HIGH PLAINS MONDAY NIGHT.

ASIDE FROM THE ROCKIES/HIGH PLAINS...ISOLATED TO WIDELY SCATTERED
THUNDERSTORMS WILL ALSO BE POSSIBLE NEAR THE COLD FRONT ACROSS THE
COASTAL SOUTHEAST STATES AND GULF COAST REGION AS IT CONTINUES TO
SPREAD SOUTH-SOUTHEASTWARD ACROSS THESE REGIONS. 

...CO FRONT RANGE/CENTRAL HIGH PLAINS...
WEAK HEIGHT FALLS/DPVA WILL INFLUENCE THUNDERSTORM DEVELOPMENT
ACROSS THE REGION IN CONJUNCTION WITH A DEEPENING LEE-SIDE SURFACE
LOW/TROUGH AND INCREASING LOW-LEVEL CONVERGENCE. SUFFICIENT
HEATING/DESTABILIZATION SHOULD ALLOW SOME STRONGER UPDRAFTS TO
DEVELOP MONDAY AFTERNOON...PARTICULARLY NEAR/JUST EAST OF THE CO
FRONT RANGE WHERE MLCAPE MAY EXCEED 500 J/KG IN THE PRESENCE OF A
MOISTENING BOUNDARY LAYER. EFFECTIVE SHEAR ON THE ORDER OF 35-40 KT
COULD ALLOW FOR SOME SUSTAINED MULTICELLS/BRIEF SUPERCELLS CAPABLE
OF MARGINALLY SEVERE HAIL. CONTINUED EASTWARD ADVANCEMENT OF THE
UPPER LOW AND INCREASING WARM ADVECTION SHOULD ALLOW STORMS TO
SPREAD INTO THE CENTRAL HIGH PLAINS MONDAY NIGHT...ALTHOUGH ANY
SEVERE WEATHER POTENTIAL SHOULD GRADUALLY DIMINISH BY LATE EVENING.
