.SYNOPSIS...A DRY AND MILD SOUTHWESTERLY FLOW WILL PERSIST
THROUGH THE WEEKEND. A DRY COLD FRONT WILL PUSH INTO NORTHERN
UTAH TONIGHT BRINGING A BRIEF COOL-DOWN WHILE SOUTHERN UTAH
REMAINS SEASONAL.

&&

.DISCUSSION...TODAY IS EXPECTED TO BE MUCH LIKE YESTERDAY...WITH
WARM TEMPERATURES AND GUSTY SOUTHWEST WINDS AHEAD OF AN
APPROACHING TROUGH. THIS SYSTEM...CURRENTLY OVER THE PACIFIC
NORTHWEST WILL CROSS TO THE NORTH OF THE CWA OVERNIGHT...PUSHING A
COLD FRONT INTO NORTHWEST UTAH LATE THIS EVENING...AND THROUGH
CENTRAL UTAH BY TOMORROW MORNING. WITH LITTLE UPPER LEVEL
SUPPORT...THIS FRONT WILL NOT PROGRESS PAST CENTRAL UTAH. WITH
GRADUALLY INCREASING MID LEVEL MOISTURE AHEAD OF THE
SYSTEM...BUILDUPS ARE EXPECTED OVER THE HIGHER TERRAIN AGAIN THIS
AFTERNOON...SO UPDATED THE FORECAST FOR THIS AFTERNOON TO INCREASE
CLOUD COVER IN THE MOUNTAINOUS AREAS. ALSO...INCREASED TEMPS
ACROSS THE NORTHERN PART OF THE CWA BY A COUPLE OF
DEGREES...PUTTING FORECAST MAX TEMPS CLOSE TO THOSE OBSERVED
YESTERDAY. WITH DECENT 700MB WINDS...AND WARMING 700MB TEMPS
THROUGH THE DAY...EXPECT THAT TODAY WILL BE AT LEAST AS WARM AS
YESTERDAY.

A SECOND WAVE WILL MOVE ACROSS THE CWA TUESDAY...SENDING ANOTHER
WEAK FRONT INTO THE AREA. LIKE TONIGHTS FRONT...THIS SECOND FRONT
WILL ALSO BE QUITE DRY...AND OTHER THAN INCREASED CLOUDS...ITS
MAIN IMPACT WILL BE KEEPING TEMPS FROM REBOUNDING RAPIDLY.

HIGH PRESSURE BUILDS INTO THE AREA WEDNESDAY.

THE GFS HAS TRENDED TOWARDS THE EC...WITH RIDGING LIKELY THROUGH
THE END OF THE WORK WEEK.
