.DISCUSSION...A COLD FRONT WILL MOVE SOUTH THROUGH UTAH TODAY
AND WILL STALL NEAR OR JUST SOUTH OF THE PROJECT SITE THIS
AFTERNOON. WINDS WILL PICK UP OUT OF THE SOUTHWEST THIS MORNING
ONCE THE LOCAL SLOPE WINDS SWITCH TO UPSLOPE. IT DOES APPEAR THAT
WINDS WILL SHIFT TO NORTHERLY MID OR LATE AFTERNOON BUT ARE NOT
EXPECTED TO BE VERY STRONG. THE EXCEPTION WOULD BE WINDS
ASSOCIATED WITH ANY SHOWERS OR THUNDERSTORMS THAT DEVELOP MAY BE
BRIEFLY STRONG AND GUSTY...AND THERE IS A POTENTIAL FOR THESE TO
OCCUR. THIS FRONT REMAINS STALLED ACROSS SOUTHERN UTAH INTO THE
WEEKEND AND THERE WILL BE A CONTINUED THREAT OF SHOWERS AND
THUNDERSTORMS RIGHT THROUGH SUNDAY. MOST OF THESE WILL BE IN THE
AFTERNOON AND EARLY EVENING BUT THERE IS A POSSIBILITY THAT
STORMS COULD PERSIST THROUGH SATURDAY NIGHT INTO SUNDAY. WARMER
AND DRIER CONDITIONS LOOK TO RETURN TO THE AREA FOR MONDAY.
