.DISCUSSION...
FAST WEST TO NORTHWEST FLOW ALOFT WILL REMAIN IN PLACE ACROSS THE
COLORADO AND UTAH BORDER THROUGH THE NEXT 24 HOURS. HIGH TEMPERATURES
ARE EXPECTED TO COOL AROUND 10 DEGREES TODAY AND AGAIN ON SATURDAY AS
THIS FLOW PULLS DOWN A COLDER AIR MASS FROM THE NORTH. LAPSE RATES
ARE STEEP ENOUGH TODAY THAT WIND GUSTS AROUND 25 MPH WILL DEVELOP
OVER THE RIDGE TOPS. STRONG INVERSIONS SHOULD DEVELOP OVERNIGHT AS
COLDER AIR FILTERS IN AND THIS WILL HELP DELAY THE WARM UP ON
SATURDAY. WINDS WILL NOT BE AS GUSTY AND DIRECTED MORE FROM THE NORTH
ONCE MIXING INCREASES SATURDAY AFTERNOON. THE CHANCE OF PRECIPITATION
IS ALMOST ZERO SO DRY CONDITIONS CONTINUE THROUGH THE WEEKEND.
