.SYNOPSIS...HIGH PRESSURE ALOFT WILL WEAKEN TONIGHT AHEAD OF A
SERIES OF PACIFIC STORM SYSTEMS IMPACTING THE NORTHERN GREAT
BASIN DURING THE MIDDLE OF THE WEEK.

&&

.DISCUSSION...THE UPPER RIDGE OVER THE WESTERN GREAT BASIN THIS
EVENING WILL CONTINUE TO WEAKEN AHEAD OF THE NEXT ROUND OF PACIFIC
WEATHER DISTURBANCES ARRIVING ON TUESDAY. THE EMBEDDED SHORTWAVE
ENERGY IN THIS ZONAL MID-LATITUDE PATTERN ACROSS THE CENTRAL
PACIFIC THROUGH WESTERN CONUS WILL CONCENTRATE ON THE PACIFIC
NORTHWEST/NORTHERN ROCKIES THROUGH TUESDAY NIGHT.

THE STRONGEST SHORTWAVE IN THE MODEL GUIDANCE MOVING THROUGH THE
NORTHERN ROCKIES LATE TUESDAY WILL SHOVE A COLD FRONT SOUTH ACROSS
NORTHERN/CENTRAL UTAH LATE TUESDAY AFTERNOON/EVENING. SOLID LOW-
LEVEL COLD ADVECTION WILL GET LITTLE HELP TO GENERATE LIFT AS THE
MID-LEVEL COLD AIR AND DYNAMIC LIFT REMAINS MAINLY NORTH OF THE
STATE. CURRENT LOW-END POPS IN THE FORECAST LOOKS GOOD FOR NOW.

THE AMPLIFYING RIDGE ALONG THE WEST COAST ON WEDNESDAY WILL SHIFT
EAST IN TO THE GREAT BASIN ON THURSDAY. TEMPS SHOULD CLIMB QUICKLY
ONCE AGAIN HEADING INTO FRIDAY AHEAD OF THE NEXT SPLITTING PACIFIC
TROUGH FOR FRIDAY NIGHT/SATURDAY.
