.SYNOPSIS...A COLD UPPER LOW OVER THE FOUR CORNERS AREA WILL SLOWLY
DRIFT EAST INTO THE CENTRAL ROCKIES THROUGH FRIDAY. A COOL NORTHWEST
FLOW WILL FOLLOW FOR THE WEEKEND.

&&

.DISCUSSION...A BROAD UPPER LOW REMAINS IN PLACE OVER THE FOUR
CORNERS THIS EVENING. MOISTURE CONTINUES TO ROTATE AROUND THE LOW
INTO UTAH...KEEPING PARTLY TO MOSTLY CLOUDY SKIES OVER MUCH OF THE
AREA. PRECIPITATION IS NOW CONFINED MOSTLY TO SOUTHERN UTAH...AND AS
THE LOW FINALLY STARTS SHIFTING EAST OVERNIGHT...A DOWNWARD TREND IN
PRECIPITATION COVERAGE IS EXPECTED. OTHERWISE...LOCALLY GUSTY
WINDS...NORTHERLY ACROSS SOUTHERN UTAH AND EAST-NORTHEAST ACROSS
NORTHERN UTAH AND SOUTHWEST WYOMING...WILL CONTINUE THROUGH LATE
TONIGHT. TEMPERATURES IN GENERAL WILL BE WARMER THAN LAST NIGHT AS
THE AIRMASS HAS MODIFIED QUITE A BIT TODAY...AND CLOUD COVER AND
WINDS WILL HELP HOLD TEMPERATURES UP IN MANY AREAS. AS A
RESULT...NOT EXPECTING WIDESPREAD HARD FREEZE CONDITIONS
OVERNIGHT...BUT CANNOT RULE OUT THAT OCCURRING IN SOME ISOLATED AND
NORMALLY COLDER SPOTS.

EXPECT LINGERING VALLEY RAIN AND MOUNTAIN SNOW SHOWERS ACROSS THE
SPINE OF UTAH AND EASTERN VALLEYS TOMORROW BEFORE THE LOW PULLS OUT
OF THE AREA.

MADE ONLY A FEW MINOR UPDATES TO THE FORECAST FOR THE REST OF
TONIGHT.

&&

.AVIATION...NORTH NORTHEAST WINDS ARE EXPECTED TO GENERALLY PREVAIL
AT THE SLC TERMINAL THROUGH ABOUT 09Z TONIGHT BUT PERIODIC SHIFTS TO
THE SOUTHWEST OR OTHER DIRECTIONS ARE POSSIBLE DUE TO EDDYING
EFFECTS. AFTER 09-10Z EXPECT A SHIFT TO THE SOUTHEAST ALTHOUGH THERE
IS A 20 PERCENT CHANCE OF REMAINING NORTHERLY THROUGH FRIDAY
MORNING. NO CIG ISSUES ARE ANTICIPATED.
