AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
957 AM MDT WED SEP 12 2007

.SYNOPSIS...HIGH PRESSURE ALOFT WILL BUILD ACROSS THE REGION
THROUGH FRIDAY. SOUTHWEST FLOW IS EXPECTED TO DEVELOP ON FRIDAY AND
INCREASE MOISTURE THROUGH THE WEEKEND.

&&

.DISCUSSION...HIGH PRESSURE IS BUILDING INTO THE STATE BEHIND THE
UPPER LOW...WHICH IS NOW SPINNING OVER COLORADO. THE RESULTING
DRY AND STABLE AIRMASS SHOULD KEEP SKIES MOSTLY CLEAR AS MAX
TEMPERATURES WARM TO VALUES WELL ABOVE CLIMO.

A LITTLE BIT MORE IN THE WAY OF CLOUD COVER IS EXPECTED
TOMORROW...BUT WITH THE RIDGE AXIS OVER HEAD THE AIRMASS SHOULD
REMAIN STABLE ENOUGH TO SUPPRESS AFTERNOON CONVECTION. A PACIFIC
TROUGH MOVING ONSHORE IS STILL EXPECTED TO SHIFT THE FLOW ALOFT
TO THE SOUTHWEST AND INCREASE IT...WHICH WILL ALLOW MOISTURE TO
SPREAD INTO THE STATE. WITH THE INCREASED FLOW...FRIDAY SHOULD BE
THE HOTTEST DAY OF THE FORECAST PERIOD.

MODELS AGREE THAT THE TROUGH WILL REMAIN ALONG THE CALIFORNIA
COAST OVER THE WEEKEND BEFORE MOVING EASTWARD. IF THIS PANS
OUT...CONVECTION WOULD BE ENHANCED MONDAY OUT AHEAD OF THE TROUGH
WITH SIGNIFICANT DRYING FOR TUESDAY. THIS WOULD ALSO PUSH A COLD
FRONT THROUGH THE STATE MONDAY AND TUESDAY...BRINGING
TEMPERATURES BACK TO SEASONAL NORMALS.

NO UPDATES EXPECTED TO THE FORECAST THIS MORNING.

&&

.AVIATION...SOUTHEAST WINDS SHOULD PERSIST AT THE SLC TERMINAL
UNTIL THE NORTHWESTERLY LAKE BREEZE DEVELOPS BETWEEN 19Z AND
20Z...A BIT LATER THAN USUAL. NO OTHER AVIATION ISSUES ARE
EXPECTED.

&&

.FIRE WEATHER...A DRY AIRMASS ACROSS THE DISTRICT SHOULD LIMIT ANY
CONVECTIVE DEVELOPMENT THIS AFTERNOON RESTRICTED TO FLAT CUMULUS
OVER THE HIGHER TERRAIN. INCREASING WESTERLY FLOW ALOFT THIS
AFTERNOON SHOULD ALLOW FOR BETTER VENTILATION THAN WHAT WAS OBSERVED
TUESDAY. ADDITIONALLY...THESE WINDS SHOULD RESULT IN CRITICAL FIRE
WEATHER CONDITIONS ACROSS THE FAR NORTHERN UT MOUNTAINS.
SOUTHWESTERLY FLOW ALOFT IS FORECAST TO SPREAD ACROSS THE DISTRICT
THROUGH THE REMAINDER OF THE WEEK INTO THE UPCOMING WEEKEND. THIS
SHOULD ALLOW FOR GOOD TO EXCELLENT MIXING ACROSS MOST OF THE
DISTRICT...WITH AN INCREASING THREAT OF AFTERNOON AND EVENING
THUNDERSTORMS ACROSS THE HIGHER TERRAIN.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...RED FLAG WARNING UNTIL 9 PM WEDNESDAY FOR UTAH FIRE WEATHER
ZONE 426.

WY...NONE.
