.SYNOPSIS...A COLD FRONT WILL MOVE ACROSS UTAH TODAY AND TONIGHT.
ANOTHER STORM SYSTEM WILL IMPACT THE AREA FRIDAY NIGHT WITH HIGH
PRESSURE BUILDING FOR THE WEEKEND.

&&

.DISCUSSION...CLOUDS ARE BUILDING ACROSS THE STATE AS A COLD FRONT
ENTERS THE AREA. LINE OF PRECIP OVER WESTERN UTAH LOOKS TO BE IN
ASSOCIATION WITH THE BOUNDARY. ADDITIONAL DEVELOPMENT IS EXPECTED
LATER THIS AFTERNOON...PRIMARILY IN THE NORTH... WITH THE ARRIVAL
OF THE ASSOCIATED UPPER TROUGH. OVER SOUTHERN UTAH...DRIER
CONDITIONS WILL PREVAIL...AND WINDS WILL INCREASE THIS AFTERNOON
AS THE FRONT MOVES CLOSER. SHOWER ACTIVITY WILL SHIFT SOUTH THIS
EVENING AND INTO THE OVERNIGHT HOURS AND MILD FGEN FORCING WILL
RESULT IN BETTER QPF IN CENTRAL AND SOUTHERN UTAH THAN IN
NORTHERN UTAH TODAY.

SURFACE RIDGING SHOULD MOVE IN FOR THURSDAY AS THE SYSTEM EXITS
INTO COLORADO...RESULTING IN A RELATIVELY QUIET DAY. BEHIND THE
FRONT...MAXES SHOULD BE ABOUT 10F COOLER THAN YESTERDAY...RIGHT
AROUND CLIMO...SO TYPICAL SPRING CONDITIONS SHOULD CONTINUE TO
PREVAIL. ALL MODELS BRING ANOTHER STORM SYSTEM/COLD FRONT THROUGH
THE STATE ON FRIDAY. THIS ONE LOOKS SIMILAR TO THE SYSTEM TODAY

EXPECTED TO DEVELOP SATURDAY AFTERNOON THROUGH THE END OF THE
WEEKEND.
