.PREV DISCUSSION... /ISSUED 0212 AM CDT TUE JUL 07 2015/

...SYNOPSIS...
THE UPPER RIDGE OVER THE SOUTHWESTERN U.S. WILL BEGIN TO SHIFT
EASTWARD AS THE UPPER LOW OFF THE CENTRAL CA COAST WEDNESDAY MORNING
MOVES INLAND BY THE END OF THE PERIOD. THIS WILL RESULT IN ENHANCED
DEEP LAYER SOUTHWESTERLY FLOW OVER THE SOUTHWESTERN DESERTS AND
SCOURING OUT OF THE MIDLEVEL MOISTURE THAT HAS PERSISTED OVER THE
LAST SEVERAL DAYS/WEEKS FROM THE LOWER CO RIVER VALLEY INTO SOUTHERN
UT AND CENTRAL AZ.

...PORTIONS OF THE LOWER CO VALLEY INTO NORTHWEST AZ...

FUEL CONDITIONS WILL BE THE MAIN LIMITING FACTOR AT THIS POINT FOR
THE LOWER CO VALLEY AND NORTHWEST AZ AS THE APPROACHING UPPER LOW
SERVES TO ERODE MIDLEVEL MOISTURE THAT HAS RESIDED OVER THE REGION
AS OF LATE. AS SUCH...FUELS ARE GENERALLY MIXED WITH POCKETS OF DRY
CONDITIONS. RH VALUES WILL FALL INTO THE TEENS AS TEMPERATURES WARM
INTO THE 90S TO NEAR 100 DEGREES IN THE LOWER ELEVATIONS. AS DEEP
BOUNDARY LAYER MIXING OCCURS...SOUTH/SOUTHWEST WINDS WILL INCREASE
TO AROUND 15 MPH WITH GUSTS TO 20-30 MPH DURING THE AFTERNOON. WHERE
FUELS ARE DRY...AN ELEVATED FIRE WEATHER THREAT WILL EXIST.
