AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1003 AM MDT FRI OCT 2 2009

.SYNOPSIS...A WEAK RIDGE OVER THE AREA TODAY WILL BE FOLLOWED BY A
COLD PACIFIC TROUGH ARRIVING LATE IN THE WEEKEND. COOLER
TEMPERATURES AND PRECIPITATION WILL SETTLE INTO THE STATE
SUNDAY...AND REMAIN OVER THE REGION THROUGH EARLY NEXT WEEK.

&&

.DISCUSSION...MOSTLY CLEAR SKIES EXIST ACROSS MUCH OF THE FORECAST
AREA THIS MORNING...WITH ONLY SOME PASSING CIRRUS TO SPEAK OF.
THIS WILL REMAIN THE CASE THROUGH TODAY...AS WEAK HIGH PRESSURE
PERSISTS OVER THE AREA. SLOW BUT STEADY WARMING AND DRYING WILL
CONTINUE THROUGH TOMORROW...WITH MOST AREAS EXPECTED TO SEE
AFTERNOON HIGHS ONLY A COUPLE DEGREES BELOW SEASONAL NORMALS ON
SATURDAY.

HOWEVER...THESE WARMER TEMPS WILL BE SHORT-LIVED...AS ANOTHER COOL
PACIFIC TROUGH IS EXPECTED TO MOVE INTO THE AREA LATE SATURDAY
INTO SUNDAY. THIS WILL LEAD TO COLDER...MOISTER...AND MORE
UNSTABLE WEATHER HEADING INTO THE BEGINNING OF NEXT
WEEK...PARTICULARLY IN THE NORTHERN HALF OF THE CWA. DETAILS
BEYOND MONDAY ARE SOMEWHAT UNCERTAIN...AS THE TROUGH SPLITS
DIRECTLY ON TOP OF THE WESTERN CONUS...WITH MOST SOLUTIONS
PRODUCING A CUT-OFF LOW OVER SOUTHERN CALIFORNIA BY WEDNESDAY
MORNING. WILL TRY TO GLEAN SOME MORE CERTAINTY FROM THE 12Z MODEL
RUNS AND ENSEMBLES...BUT SUSPECT THAT THE SOLUTIONS WILL CONTINUE
TO WAVER OVER THE NEXT COUPLE DAYS IN THIS UNCERTAIN PATTERN.

THE CURRENT FORECAST LOOKS GOOD AND NO UPDATES ARE PLANNED FOR
THIS MORNING.

&&

.AVIATION...SURFACE WINDS AT THE SLC TERMINAL ARE EXPECTED TO
SWITCH TO THE NORTHWEST BETWEEN 17Z AND 19Z. VFR CONDITIONS UNDER
MOSTLY CLEAR SKIES WILL PERSIST THROUGH TODAY.

&&

.FIRE WEATHER...HIGH PRESSURE OVER UTAH WILL GRADUALLY MOVE EAST
TODAY ALLOWING SOUTHWESTERLY FLOW ALOFT TO SPREAD ACROSS THE REGION.
THIS SOUTHWESTERLY FLOW WILL ALLOW FOR A WARMING TREND TODAY THROUGH
SATURDAY. AS THIS FLOW STRENGTHENS ON SATURDAY IT WILL RESULT IN
WINDY CONDITIONS ACROSS THE SOUTHERN THIRD OF UTAH...AND COMBINED
WITH A VERY DRY AIRMASS WILL CREATE FIRE WEATHER CONCERNS. WINDS
WILL BE STRONGER SUNDAY MORNING AHEAD OF THE COLD FRONT EXPECTED
AROUND NOON BUT HUMIDITY WILL BE ABOVE 15 PERCENT. HAVE NOT
DISCUSSED FUEL MOISTURE AND POSSIBLE FIRE HEADLINES WITH THE EGBCC
YET...BUT WILL BEFORE AFTERNOON PACKAGE. THE COLD PACIFIC STORM
SYSTEM EXPECTED SUNDAY WILL LINGER THROUGH EARLY NEXT WEEK. THIS
WILL BRING COLDER TEMPERATURES...ALONG WITH ANOTHER ROUND OF VALLEY
RAIN AND MOUNTAIN SNOWFALL TO THE NORTHERN HALF OF UTAH.
