.SYNOPSIS...A TROUGH OVER THE WEST COAST STATES WILL MOVE INTO THE
GREAT BASIN LATER TODAY.  THIS TROUGH WILL MOVE ACROSS UTAH TONIGHT
THROUGH EARLY SATURDAY.  HIGH PRESSURE ALOFT WILL RETURN TO THE
REGION EARLY NEXT WEEK.

.DISCUSSION...TAKING THE NEW 12Z ETA LITERALLY WOULD IMPLY THAT
NEARLY ALL OF THE FORECAST AREA WILL BE DOMINATED BY SUBSIDENCE AND
RELATIVELY STABLE AIRMASS THROUGH 00Z WITH SHOWERS AND THUNDERSTORMS
BECOMING WIDESPREAD AFTER THAT AND CONTINUING OVERNIGHT AND INTO
SATURDAY MORNING.

LATEST SATELLITE IMAGERY SUGGESTS ACTIVITY MAY START EARLIER IN
SOUTHWEST UT AND GOES PW SHOWS MORE MOISTURE OVER THE NW AND SE
PORTIONS OF UT THAN IN THE LATEST MODEL. JET STREAK OVER LAKE POWELL
AREA ALSO APPEARS BETTER DEFINED IN IMAGERY THAN IN MODEL ISOTACH
FIELDS.  SO HAVE UPPED POPS IN SOUTHERN MOUNTAINS FOR TODAY/TONIGHT.
CONVECTION MAY NOT PRODUCE MUCH MEASURABLE RAIN IN THE SOUTH WHERE
LOW LEVELS ARE STILL FAIRLY DRY...BUT STRONG WINDS LIKELY WITH ANY
STORMS.

ALSO UPDATED TO ADD WIND TO LAKE POWELL AND SE UT ZONES....AND MADE
SOME MINOR WORDING CHANGES TO A FEW NORTHERN ZONES TO TAKE OUT EARLY
MORNING SHOWERS NOW THAT SHORT WAVE THAT CAME THROUGH LAST NIGHT HAS
CLEARED THE AREA.
