AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
948 PM MDT TUE MAR 11 2014

.SYNOPSIS...A STORM SYSTEM WILL LINGER OVER EXTREME SOUTHERN UTAH
MIDWEEK...THEN TURN EAST THROUGH NORTHERN ARIZONA ON THURSDAY. A
STORM SYSTEM IS EXPECTED TO AFFECT THE EASTERN HALF OF UTAH FRIDAY
NIGHT AND SATURDAY BEFORE HIGH PRESSURE RETURNS FOR THE LATTER
HALF OF THE WEEKEND.

.DISCUSSION...THE TROUGH THAT HAS BEEN IMPACTING THE WEATHER OVER
THE GREAT BASIN IS MOVING BACK INTO SOUTHERN NEVADA AND CALIFORNIA
THIS EVENING. STABILITY INCREASING OVER UTAH IN THE WAKE OF THE
SYSTEM AND ANY LINGERING SNOW SHOWERS HAVE DISSIPATED THIS
EVENING. UPDATED THE FORECAST EARLIER TO REMOVE POPS FROM THE
EVENING PERIOD.

PLACEMENT OF THE EXITING TROUGH HAS PUT THE FORECAST AREA UNDER
NORTHEASTERLY FLOW ALOFT WHICH IS CAUSING A BIT OF CANYON WINDS
ALONG THE WASATCH FRONT AND AROUND WASHINGTON COUNTY. MAX GUSTS SO
FAR ARE IN THE 25 TO 30 KT RANGE AND FLOW IS EXPECTED TO CHANGE
LITTLE OVERNIGHT. STRONGER GUSTS ARE EXPECTED ALONG US-6 BETWEEN
PRICE AND GREEN RIVER WHERE A WIND ADVISORY REMAINS IN EFFECT
THROUGH THE EARLY MORNING HOURS. FLOW BECOMES MORE SWLY BY
TOMORROW AFTERNOON...ENDING THE THREAT.

THE TROUGH TO OUR SOUTHWEST SLOWLY MAKES ITS WAY BACK EAST OVER
NORTHERN ARIZONA THROUGH FRIDAY. THIS SHOULD BRING A BIT OF
MOISTURE AND INSTABILITY BACK INTO SOUTHERN UTAH BY THURSDAY
BEFORE A DRIER NORTHWEST FLOW MOVES IN FRIDAY. A GRAZING SYSTEM IS
EXPECTED TO IMPACT PRIMARILY THE EASTERN HALF OF UTAH FRIDAY NIGHT
INTO SATURDAY BEFORE HIGH PRESSURE BUILDS BACK IN FOR THE EARLY
PART OF NEXT WEEK.

NO ADDITIONAL UPDATES EXPECTED TO THE FORECAST THIS EVENING.
