AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SALT LAKE CITY UT 928 AM MDT TUE JUL 10 2007 .SYNOPSIS...HIGH PRESSURE WILL REMAIN ACROSS THE EASTERN GREAT BASIN. INCREASING MID-LEVEL MOISTURE WILL BRING AN INCREASING CHANCE OF THUNDERSTORMS TO THE HIGHER TERRAIN THROUGH THE END OF THE WEEK. && .DISCUSSION...HIGH PRESSURE OVER THE NORTHERN PLAINS HAS CREATED AN EASTERLY PRESSURE GRADIENT BETWEEN EVANSTON WYOMING AND THE NORTHERN WASATCH FRONT. THIS GRADIENT CAUSED LOCAL CANYON WINDS TO DEVELOP THIS MORNING IN SEVERAL LOCATIONS. THESE WINDS ARE ALREADY DIMINISHING AND SHOULD END LATER THIS MORNING. SMOKE ALOFT FROM WILDFIRES AROUND THE WEST WILL REMAIN OVER MOST OF THE AREA TODAY. HOWEVER...RESTRICTIONS TO SURFACE VISIBILITY WILL BE LOCALIZED TO AREAS IMMEDIATELY ADJACENT TO ONGOING WILDFIRES. WILL UPDATE LATER ON THIS MORNING TO REMOVE MENTION OF LOCAL CANYON WINDS...OTHERWISE CURRENT FORECAST IS ON TRACK. MID-LEVEL MOISTURE WILL CONTINUE TO INCREASE OVER THE REGION FOR THE NEXT SEVERAL DAYS AS THE RIDGE AXIS MOVES INTO A MORE FAVORABLE LOCATION. PRECIPITABLE WATER VALUES OF OVER .80 INCHES ARE FORECAST BY BOTH THE GFS AND NAM BY FRIDAY. GFS MAINTAINS THESE VALUES THROUGH MONDAY. CURRENT POP FORECAST REPRESENTS THIS PATTERN WELL.
