.DISCUSSION...BROAD HIGH PRESSURE EXTENDS E-W FROM THE NRN CA COAST
ACROSS THE GREAT BASIN INTO THE CENTRAL ROCKIES THIS EVE. DEEP
MOISTURE IN PLACE S OF THE RIDGE AXIS CONTINUES TO GENERATE LOCAL
HEAVY RAINS ACROSS FAR SRN UT. THESE HAVE ENDED FOR THE MOST PART
ALTHO SMALLER STORMS CONTINUE ACROSS FAR SRN WASHINGTON COUNTY AT
THIS TIME.

CONSIDERABLE ANVIL BLOWOFF FROM THE STRONG STORMS EARLIER HAS SPREAD
DENSE CIRRUS ACROSS MUCH OF THE CWA WITH SOME OF THIS MAKING IT ALL
THE WAY TO THE ID BORDER. THIS WILL TEND TO DISSIPATE AS THE NIGHT
GOES ON BUT SOME IS LIKELY TO LINGER INTO TUE KEEPING MIN TEMPS

THE RIDGE AXIS IS FORECAST ROTATE ANTI-CYCLONICALLY TOMORROW VEERING
THE FLOW ACROSS THE SWRN 1/2 OF THE CWA TO MORE SOUTHERLY AND
ALLOWING THE MOISTURE IN PLACE ACROSS THE SOUTH TO START SPREADING
