..DISCUSSION...
UPR FLOW REGIME WILL SPLIT EARLY NEXT WEEK AS THE NRN PAC TROUGH
BEGINS TO SPREAD INLAND. THE PREFERRED 00Z GFS/ECMWF...DEPICTING
THIS SPLIT FLOW REGIME...DIFFER IN THE TIMING OF THE
TROUGH...HOWEVER...WITH THE ECMWF MUCH FASTER. RICHER BOUNDARY
LAYER MOISTURE...NOW RELEGATED TO THE SRN THIRD OF THE
COUNTRY...SHOULD BEGIN TO RETURN NWD AHEAD OF THIS TROUGH SOMETIME
DURING THE MID-WEEK TIME FRAME...POTENTIALLY INCREASING BUOYANCY.
BUT...THE SIGNIFICANT TIMING DIFFERENCES RENDER THE MEDIUM RANGE SVR
PREDICTABILITY VERY LOW AND DOES NOT JUSTIFY A RISK AREA ATTM.
