SPOT FORECAST FOR WILDFIRE ACADEMY...USDA FS
NATIONAL WEATHER SERVICE GRAND JUNCTION CO
643 PM MDT TUE JUN 2 2009

FORECAST IS BASED ON IGNITION TIME OF 1200 MDT ON JUNE 03.
IF CONDITIONS BECOME UNREPRESENTATIVE...CONTACT THE NATIONAL WEATHER
SERVICE.

.DISCUSSION...A DRIER AIR MASS WILL BEGIN TO MOVE OVER THE AREA ON
WEDNESDAY. HOWEVER ENOUGH LINGERING MOISTURE WILL PERSIST FOR THE
DEVELOPMENT OF SCATTERED SHOWERS AND THUNDERSTORMS IN THE
AFTERNOON AND EVENING. COVERAGE WILL NOT BE QUITE AS WIDESPREAD AS
WE HAVE SEEN FOR THE LAST FEW DAYS AND ACTIVITY WILL QUICKLY DIE
OUT AS THE SUN SETS. THEN DRIER AND WARMER CONDITIONS ARE EXPECTED
ON THURSDAY AS THE UPPER RIDGE AXIS SHIFTS EAST.

A DEEP PACIFIC LOW PRESSURE SYSTEM WILL MOVE INTO THE GREAT BASIN
ON FRIDAY. A MODERATE SOUTHWEST FLOW WILL RESULT IN AN INCREASE
IN MOISTURE OVER THE AREA ALLOWING SCATTERED THUNDERSTORMS TO
DEVELOP IN THE AFTERNOON. HOWEVER THE TIMING OF THIS SYSTEM HAS
BEEN UNCERTAIN...SO CONFIDENCE IS NOT HIGH.
