AREA FORECAST DISCUSSION...UPDATED FIRE WEATHER
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
405 AM MDT THU JUL 14 2011

.SYNOPSIS...SOUTHWESTERLY FLOW ALOFT WILL BRING A CONTINUED DRYING
TREND ACROSS THE REGION THROUGH SATURDAY. MOISTURE LOOKS TO RETURN
TO THE REGION LATE IN THE WEEKEND INTO EARLY NEXT WEEK.

&&

.DISCUSSION...AN UPPER LEVEL TROUGH OVER THE PACIFIC NORTHWEST COAST
WILL SLOWLY PROGRESS INLAND TODAY. THIS WILL ALLOW A DRY SOUTHWEST
FLOW TO CONTINUE TO SPREAD INTO UTAH. PRECIPITABLE WATER VALUES HAVE
ALREADY FALLEN TO BELOW A HALF INCH ACROSS THE SOUTHWESTERN HALF OF
THE CWA. THIS DRY AIRMASS WILL CONTINUE TO SPREAD INTO THE REMAINDER
OF THE AREA TODAY. HOWEVER...BEFORE IT DOES SO...ISOLATED CONVECTION
IS STILL POSSIBLE MAINLY ACROSS THE HIGH TERRAIN OF NORTHEAST AND
FAR NORTHWEST UTAH THIS AFTERNOON.

SEVERAL SHORTWAVE DISTURBANCES WILL CONTINUE TO SWING ACROSS THE
PACIFIC NORTHWEST OVER THE NEXT FEW DAYS...KEEPING A MEAN TROUGH
POSITION OVER THE WEST COAST THROUGH THE WEEKEND. HOWEVER...THE HIGH
PRESSURE OVER THE CENTRAL PLAINS WILL RETROGRADE ENOUGH TO ALLOW
MOISTURE TO SPREAD BACK INTO THE EASTERN PORTIONS OF THE AREA OVER
THE WEEKEND AND INTO THE EARLY PART OF NEXT WEEK.
OTHERWISE...TEMPERATURES WILL BE NEAR TO SLIGHTLY BELOW NORMAL THE
NEXT COUPLE OF DAYS BEFORE WARMING OVER THE WEEKEND AS HEIGHTS RISE.

THE TROUGH IS EXPECTED TO EJECT INLAND DURING THE FIRST HALF OF THE
WEEK...PUSHING THE RIDGE AXIS EAST. THIS WILL BRING A DRYING TREND
TO THE AREA FOR THE MIDDLE PART OF NEXT WEEK.

&&

.AVIATION...VFR CONDITIONS ARE EXPECTED AT THE SLC TERMINAL THROUGH
THE FORECAST PERIOD. SOUTHEAST WINDS WILL PREVAIL THROUGH ABOUT
15-16Z THEN SHIFT TO MORE SOUTHERLY AND INCREASE WITH GUSTS OVER 25
KTS LIKELY AFTER 16Z.

&&

.FIRE WEATHER...A BROAD SOUTHWEST FLOW AHEAD OF A TROUGH SETTLING
ALONG THE PACIFIC NORTHWEST AND NORTHERN CALIFORNIA COAST WILL BRING
DRY AIR IN ACROSS THE DISTRICT TODAY AND FOR THE NEXT SEVERAL DAYS.
ALTHOUGH SOUTH WINDS WILL BE AT OR JUST ABOVE CRITICAL LEVELS AND
RHS BELOW 15 PERCENT ACROSS THE WESTERN AND SOUTHERN PORTIONS OF THE
AREA TODAY THE NATIVE GRASSES AND SAGE AS REPORTED BY THE EASTERN
GREAT BASIN GACC REMAIN ON THE GREEN SIDE FOR ALL BUT THE DIXIE AREA
OF UTAH. CONTINUOUS DRY WINDS...GUSTY WINDS AND LOW RHS FOR THE NEXT
FEW DAYS WILL LIKELY CHANGE THE FUEL STATUS BY THIS WEEKEND FOR
OTHER SOUTHERN AND WESTERN ZONES. THIS WILL NEED TO BE CLOSELY
WATCHED AS WINDS FOR SATURDAY AND SUNDAY GET VERY CLOSE TO EXCEEDING
CRITICAL LEVELS.

.SLC WATCHES/WARNINGS/ADVISORIES...
