DISCUSSION
THROUGH SUNDAY.
STRONG HIGH PRESSURE BUILDING ACROSS THE WESTERN US WILL ALLOW FOR A
CONTINUATION OF DRY CONDITIONS OVER THE NEXT SEVERAL DAYS. THE ONLY
SIGNIFICANT WEATHER IMPACTS EXPECTED THROUGH MID-WEEK WILL BE
PERSISTENT NORTHERLY WINDS DOWN THE COLORADO RIVER VALLEY, WHERE
SURFACE PRESSURE GRADIENTS REMAIN TIGHT. THE STRONGEST WINDS ARE
EXPECTED NEAR AND BELOW DAVIS DAM, WHERE GUSTS OF 30 TO 40 MPH WILL
BE POSSIBLE. WAVE HEIGHTS BETWEEN COTTONWOOD COVE AND DAVIS DAM WILL
LIKELY BE IN THE 1 TO 3 FOOT RANGE, AND BOATERS OPERATING IN THESE
AREAS SHOULD EXERCISE CAUTION.
AS THE RIDGE BUILDS OVER THE AREA, TEMPERATURES WILL CONTINUE TO
CLIMB A FEW DEGREES THROUGH MID-WEEK BEFORE LEVELING OFF DURING THE
SECOND HALF OF THE WEEK. TEMPERATURE INVERSIONS ABOVE THE SURFACE
MAY KEEP GROUND LEVEL TEMPERATURES A LITTLE COOLER IN SHELTERED
VALLEYS; HOWEVER, READINGS A FEW DEGREES ABOVE NORMAL ARE STILL
EXPECTED. AS THE HIGH BEGINS TO SLOWLY WEAKEN BY THE WEEKEND, A
SLIGHT COOLING TREND IS EXPECTED, ALTHOUGH READINGS WILL STILL
LIKELY REMAIN NEAR TO SLIGHTLY ABOVE NORMAL THROUGH SUNDAY. NO
PRECIPITATION IS EXPECTED THROUGH THE SEVEN-DAY PERIOD.
