...SYNOPSIS/FCST...
MID-LVL WAVE CURRENTLY MOVING INTO THE NRN ROCKIES IS EXPECTED TO
TRANSLATE SEWD ACROSS THE NRN/CNTRL PLNS ON THURSDAY AS A STRONGER
UPR TROUGH PROGRESSES TOWARD THE PAC CST THURSDAY NIGHT.
SUBTROPICAL IMPULSE OVER BAJA WILL EJECT NEWD INTO PARTS OF THE
DESERT SW AHEAD OF THE LATTER TROUGH.
RETURN FLOW AHEAD OF THE PLNS TROUGH WILL ADVECT A MODIFIED CP AIR
MASS NWD THROUGH TX INTO KS THURSDAY AFTN BENEATH AN INCREASING
MAGNITUDE IN THE ELEVATED MIXED LAYER. POTENTIAL INSTABILITY IN THE
COLUMN WILL GRADUALLY INCREASE OWING TO MODEST MOISTENING TIED TO
ASCENT ASSOCD WITH THE IMPULSE. HOWEVER...INHIBITION WILL LIKELY
REMAIN RELATIVELY STRONG AND LIMIT THE RISK FOR TSTMS ACROSS THE
PLNS ON THURSDAY.
ELSEWHERE...VERY ISOLD TSTMS MAY OCCUR ALONG THE CA/AZ/MEXICO BORDER
AND ACROSS CSTL CNTRL CA IN ADVANCE OF THE PAC CST AND DESERT SW
DISTURBANCES. BUT...PROBABILITY SHOULD GENERALLY BE LESS THAN 10
PERCENT.
