VALID 081200Z - 131200Z
...DISCUSSION...
CONSIDERABLE VARIABILITY EXISTS AMONG THE MEDIUM RANGE FORECAST
GUIDANCE CONCERNING THE MAGNITUDE OF BLOCKING AND DEGREE OF
AMPLIFICATION WITHIN THE LARGE-SCALE PATTERN FOR THIS FORECAST
PERIOD. IT DOES APPEAR POSSIBLE THAT THE REMNANTS OF A COUPLE OF
CLOSED LOWS COMPRISING A PORTION OF THE STILL EVOLVING EASTERN
PACIFIC BLOCK COULD EVENTUALLY MIGRATE INLAND ACROSS PARTS OF THE
INTERMOUNTAIN WEST AND ROCKIES BY LATE NEXT WEEK. HOWEVER...
POTENTIAL FOR SIGNIFICANT SURFACE CYCLOGENESIS TO THE LEE OF THE
CENTRAL AND SOUTHERN ROCKIES APPEARS LOW THROUGH THE END OF THIS
FORECAST PERIOD...WHICH PROBABLY WILL PRECLUDE ANY RISK FOR A
SUBSTANTIVE REGIONAL SEVERE WEATHER EVENT.
