NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1245 PM MDT SUN MAY 31 2009

.DISCUSSION...HIGH PRESSURE OVER THE AREA IS BEGINNING TO
WEAKEN...AND WILL MOVE OFF TO THE EAST BEGINNING MONDAY NIGHT. THE
MOISTURE THAT HAS BEEN RESPONSIBLE FOR THE AFTERNOON CONVECTION OVER
THE PAST FEW DAYS IS STILL IN PLACE. HOWEVER...DRIER AIR IS STARTING
TO MAKE ITS WAY INTO THE EXTREME SOUTHERN PORTION OF THE STATE. AS A
RESULT...THUNDERSTORM ACTIVITY WILL START LATER AND HAVE LESS
COVERAGE THAN HAS BEEN THE CASE OVER THE PAST FEW DAYS.
BECAUSE OF THE HIGH PRESSURE IN PLACE...WINDS WILL BE TERRAIN
DRIVEN. HOWEVER....WINDS IN THE VICINITY OF THUNDERSTORMS MAY BE
GUSTY AND ERRATIC AT TIMES.

A LOW PRESSURE SYSTEM IS EXPECTED TO MOVE ONTO THE CALIFORNIA COAST
MONDAY EVENING. THIS WILL RESULT IN A SOUTHWESTERLY FLOW THAT WILL
BRING A DRYING TREND TO THE AREA. THIS LOW PRESSURE SYSTEM WILL
REMAIN RELATIVELY STATIONARY THROUGH MID WEEK...KEEPING THE BURN
AREA IN A WINDY AND DRY PATTERN.
