.SYNOPSIS...A WEAK WEATHER DISTURBANCE OVER NORTHERN UTAH WILL
EXIT THE REGION LATE TONIGHT. STRONG HIGH PRESSURE DEVELOPING
OVER THE WEST COAST FRIDAY WILL BECOME QUITE STRONG ACROSS THE
ENTIRE REGION BY EARLY NEXT WEEK.

&&

.DISCUSSION...THE WEAK SHORTWAVE RACING SOUTHEAST ACROSS NORTHERN
UTAH WILL EVENTUALLY EXIT THROUGH EASTERN UTAH LATE TONIGHT. LIFT
GENERATED BY THIS DYNAMIC FEATURE WILL REMAIN SHALLOW BUT
SUFFICIENT TO PRODUCE LIGHT SNOW THROUGH LATE TONIGHT OVER
PORTIONS OF NORTHERN THROUGH EAST-CENTRAL UTAH.

HIGH PRESSURE ALOFT BUILDING IN BEHIND THIS EXITING SHORTWAVE
WILL ELIMINATE ANY LINGERING SNOW SHOWERS FOR FRIDAY. A RATHER
ENERGETIC TROUGH ENTERING THE PACIFIC NORTHWEST FRIDAY AFTERNOON
WILL TRACK EAST ACROSS THE NORTHERN ROCKIES LATE FRIDAY NIGHT
THROUGH SATURDAY. THE SOUTHERN END OF THIS FEATURE WILL LIKELY
CLIP FAR NORTHERN UTAH LATE FRIDAY NIGHT/SATURDAY MORNING. THE
RELATIVELY DRY AND STABLE AMBIENT AIR MASS AHEAD OF THIS FEATURE
WILL WORK AGAINST SNOW...THOUGH CAN NOT RULE OUT A BRIEF PERIOD
OF SNOW NEAR THE PASSING TROUGH AXIS LATE FRIDAY NIGHT THROUGH
SATURDAY MORNING.

NIGHT WILL GRADUALLY DEVELOP INTO A BROAD AND QUITE STRONG UPPER
RIDGE ACROSS THE WESTERN CONUS FOR MUCH OF THE UPCOMING WEEK.
LOOKING AT INCREASING VALLEY FOG/URBAN HAZE FROM THE VERY STABLE
CONDITIONS UNDERNEATH THE RIDGE...WITH HIGH ELEVATION LOCATIONS
LOOKING AT A SUBSTANTIAL WARMING TREND DURING THE FIRST HALF OF
THE WEEK.
