...SYNOPSIS...
THE MID LEVEL SHORTWAVE TROUGH NOW MOVING FROM CENTRAL CA INTO NV
WILL CONTINUE EWD OVER THE FOUR CORNERS BY THIS EVENING...REACHING
THE HIGH PLAINS EARLY MONDAY.  THE APPROACHING WAVE WILL INDUCE LEE
CYCLOGENESIS ACROSS ERN CO AND SLY LOW-LEVEL FLOW ACROSS THE SRN
PLAINS.  A FEW SHALLOW CONVECTIVE SHOWERS ARE EXPECTED ACROSS SE TX
WITHIN A MOISTENING WAA REGIME.  HOWEVER...LOW-LEVEL TRAJECTORIES
AND MID LEVEL LAPSE RATES DO NOT SUPPORT SUFFICIENT DESTABILIZATION
FOR THUNDERSTORMS THIS PERIOD.

...CENTRAL CA TODAY AND THE FOUR CORNERS THIS AFTERNOON...
ISOLATED LIGHTNING STRIKES HAVE BEEN NOTED IN NLDN DATA ACROSS
CENTRAL CA WITH THE INITIAL SHORTWAVE TROUGH.  THIS THREAT SHOULD
DIMINISH THIS MORNING AS THE WAVE MOVES E OF THE SIERRA

HALF OF THE DAY AS A SECOND SHORTWAVE TROUGH MOVES INLAND.  THERE 
WILL ALSO BE SOME THREAT FOR ISOLATED THUNDERSTORMS THIS AFTERNOON
INVOF THE FOUR CORNERS WHERE DAYTIME HEATING...ASCENT/COOLING MID
LEVEL TEMPERATURES...AND GRADUAL MOISTENING IN ADVANCE OF THE MID
LEVEL WAVE SHOULD RESULT IN THE DEVELOPMENT OF WEAK INSTABILITY.
