DISCUSSION
THROUGH THIS WEEKEND.
THE SYSTEM THAT BROUGHT STRONG WINDS TO THE REGION LAST NIGHT PULLS
AWAY FROM THE AREA TODAY. WITH THE TROUGH AXIS CURRENTLY CENTERED
OVER NORTHEAST UTAH, THE AREA REMAINED UNDER COOL, DRY NORTHERLY
FLOW THROUGH THE MORNING. WINDS ARE NOT NEARLY AS STRONG AT LAST
NIGHT, BUT GUST 25-35 MPH WERE REPORTED IN MANY LOCATIONS THROUGH
THE MORNING HOURS. THE STRONGEST WINDS TODAY HAVE BEEN IN THE
COLORADO RIVER VALLEY, THOUGH EVEN THERE THE NORTH WINDS HAVE BEEN
ON A DOWNWARD TREND IN THE PAST FEW HOURS AFTER THE STRONGEST GUSTS
TOPPED OUT AROUND 40 MPH THIS MORNING. WINDS WILL CONTINUE TO
DIMINISH THROUGH THE REST OF THE AFTERNOON AND BY 4 PM, GUSTS WILL
BE 25 MPH OR LESS IN FOR MOST OF THE REGION. WITH THE STRONGEST
WINDS AND HIGHEST RISK FOR WIND IMPACTS BEHIND US, LET THE HIGH WIND
WARNING IN THE COLORADO RIVER VALLEY EXPIRE. ISOLATED GUSTS TO 40
MPH ARE POSSIBLE HERE THROUGH THE EARLY AFTERNOON WHICH COULD CAUSE
IMPACTS ON THE LAKES, OTHERWISE WIDESPREAD WIND IMPACTS ARE NOT
EXPECTED. WITH NO SIGNIFICANT SYSTEMS ARE EXPECTED THE REST OF THE
WEEK, SO NOT EXPECTING WIDESPREAD WIND IMPACTS THROUGH THE WEEKEND
BREEZY AFTERNOONS WITH GUSTS 20-30 MPH ARE POSSIBLE AT TIMES,
ESPECIALLY TOMORROW AND WEDNESDAY IN THE COLORADO RIVER VALLEY AS
NORTH WINDS LINGER A FEW MORE DAYS.
TODAY WILL BE MUCH COOLER COMPARED TO RECENT CONDITIONS AS HIGH
TEMPERATURES THIS AFTERNOON ARE EXPECTED TO RUN ABOUT 10 DEGREES
BELOW NORMAL. HEIGHTS WILL INCREASE THROUGH THE WEEK AS TROUGHING
WEAKENS, WHICH WILL RESULT IN DRY CONDITIONS AND A WARMING TREND.
TEMPERATURES WILL WARM EACH DAY WITH HIGH TEMPERATURES RETURNING TO
NORMAL BY WEDNESDAY. THE WARMING TREND THEN CONTINUES INTO THE
WEEKEND, WITH ABOVE NORMAL TEMPERATURES THURSDAY ONWARD CLIMBING A
FEW DEGREES EACH DAY THE SECOND HALF OF THE WEEK. BY THE WEEKEND,
HIGH TEMPERATURES WILL RUN 5-8 DEGREES ABOVE NORMAL.
