VALID 221200Z - 271200Z
...DISCUSSION...
SPLIT FLOW PATTERN WITH NEARLY ZONAL SRN STREAM WILL CHARACTERIZE
PATTERN THROUGH MUCH OF PERIOD. PROGS ARE MORE CONSISTENT THAN
YESTERDAY WITH TRACK AND TIMING OF PACIFIC SHORTWAVE TROUGH AND
EMBEDDED LOW DESCRIBED IN DAY-3 OUTLOOK...FCST TO MOVE ACROSS
CENTRAL/SRN CA LATE DAY-3 AND EARLY DAY-4. STG CONSENSUS OF MREF
MEMBERS...AS WELL AS OPERATIONAL SPECTRAL/ECMWF...IS FOR
DEAMPLIFICATION OF THIS WAVE DAYS 4-5/22ND-24TH...AS IT MOVES EWD
ACROSS SRN ROCKIES AND SRN PLAINS. HOWEVER...CONSIDERABLE
DIFFERENCES STILL EXIST REGARDING STRENGTH OF THIS FEATURE AND ITS
EFFECT ON LOW LEVEL MASS/THERMODYNAMIC FIELDS -- INCLUDING GULF
MOISTURE RETURN -- AHEAD OF SWD-MOVING SFC COLD FRONT OVER SRN
PLAINS.
