...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...

INTENSIFICATION OF WRN CONUS TROUGH IS FORECAST DURING THE DAY TWO
PERIOD WITH STRONG HEIGHT FALLS DEVELOPING THROUGH THE LOWER CO
VALLEY...FOUR CORNERS REGION INTO CNTRL ROCKIES.  IN THE
LOW-LEVELS...SURFACE COLD FRONT WILL PUSH SEWD THROUGH THE UPPER MS
VALLEY AND UPPER GREAT LAKES WITH THIS BOUNDARY EXTENDING SWWD TO
DEEPENING LOW PRESSURE OVER CO.  COLD FRONT WILL THEN TRAIL SWWD
FROM THIS LOW INTO THE LOWER CO VALLEY AND EVENTUALLY INTO SRN
ROCKIES.

...S FL AND THE KEYS...

A MOIST AND WEAKLY UNSTABLE AIR MASS IS EXPECTED TO PERSIST INVOF
STALLED FRONTAL BOUNDARY.  WEAK CAPPING COUPLED WITH PERSISTENT
LOW-LEVEL CONVERGENCE AND APPROACH OF SRN STREAM IMPULSE /NOW OVER
THE NWRN GULF OF MEXICO/ SHOULD ALL CONTRIBUTE TO ISOLATED/SCATTERED
TSTM DEVELOPMENT.  WEAK LAPSE RATES AND SHEAR WILL PRECLUDE ANY
SEVERE THREAT.

OTHER MORE ISOLATED TSTM ACTIVITY WILL BE POSSIBLE FROM ERN PORTIONS
OF THE GREAT BASIN THROUGH THE FOUR CORNERS REGION INTO CNTRL CO
INVOF SURFACE FRONT AS STRONGER HEIGHT FALLS SPREAD EWD.  MODEST
LAPSE RATES WILL EXIST THOUGH RELATIVELY DRY AIR MASS WILL LIMIT
DESTABILIZATION.  THIS THREAT SHOULD REMAIN QUITE ISOLATED AND NO
GENERAL THUNDER AREA WILL BE INCLUDED ATTM.
