AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
907 AM MDT MON SEP 13 2010

.SYNOPSIS...A WARM AND DRY SOUTHWEST FLOW WILL REMAIN OVER THE AREA
TODAY. A WEAK DISTURBANCE WILL CROSS NORTHERN UTAH TUESDAY NIGHT.
THE RIDGE WILL REDEVELOP OVER THE REGION WEDNESDAY AND BEYOND.

&&

.DISCUSSION...STRONG HIGH PRESSURE REMAINS CENTERED OVER THE
SOUTHERN GREAT PLAINS THIS MORNING WHILE A TROUGH REMAINS SITUATED
JUST OFF THE WEST COAST. THIS SCENARIO WILL KEEP UTAH UNDER A
GENERALLY LIGHT TO MODERATE SOUTHWEST FLOW. MOISTURE IS SCARCE
WITH PRECIPITABLE WATER VALUES REMAINING UNDER HALF AN INCH. ONLY
SIGNIFICANT MOISTURE IS CURRENTLY NEAR THE FOUR CORNERS AREA...OR
BASICALLY OUT OF THE CWA. A VERY WEAK DISTURBANCE WILL EJECT OUT
OF THE TROUGH AND LIFT NORTHEAST ACROSS UTAH TODAY. THIS WILL
CAUSE SOME MOISTURE TO BE PULLED UP INTO SOUTHERN NEVADA LATER
TODAY AND THEN DRIFT NORTH TOMORROW. THIS COULD KICK OFF A FEW
THUNDERSTORMS WHICH MAY DRIFT EAST INTO SOUTHWEST UTAH...BUT THE
CHANCES ARE SMALL. NO UPDATES NEEDED.

&&

.AVIATION...VFR CONDITIONS WILL PREVAIL AT THE KSLC TERMINAL UNDER A
GENERALLY DRY AND STABLE SW FLOW ALOFT. LIGHT EAST WINDS AT
MID-MORNING WILL TURN MORE TO THE SOUTHEAST AND INCREASE THROUGH THE
BALANCE OF THE MORNING. THE DIURNAL WIND SWITCH TO THE NORTHWEST
SHOULD HOLD OFF UNTIL 18-20Z THIS AFTERNOON.

&&

.FIRE WEATHER...A RATHER DRY SOUTHERLY FLOW REMAINS OVER MUCH OF
UTAH THIS MORNING. THE EXCEPTION TO THIS IS THE 4-CORNERS REGION
WHERE SOME MOISTURE DID WORK NORTH THROUGH ERN AZ OVERNIGHT.
MOISTURE WILL WORK NORTH THROUGH WRN AZ/SRN NV TODAY...THEN SPILL
OVER INTO WRN UTAH THIS EVENING. ISOLATED SHOWERS/STORMS ARE
POSSIBLE TONIGHT...WITH THIS ACTIVITY SPREADING EAST WITH THE
MOISTURE TUESDAY. A WEATHER DISTURBANCE MOVING EAST THROUGH SRN UTAH
WEDNESDAY WILL SPAWN SOME SHOWERS/STORMS...THEN A DRIER AIRMASS WILL
SPREAD IN ROM THE WEST AND END THE THREAT FOR LATE IN THE WEEK.

INCREASING SOUTHERLY WINDS COMBINED WITH ALREADY LOW SURFACE
HUMIDITIES WILL BRING A THREAT OF HAZARDOUS FIRE WEATHER CONDITIONS
TO THE WRN FIRE DISTRICTS BY TUESDAY AFTERNOON. THE GREATEST THREAT
WILL CENTER ON THE NORTHWESTERN AND WEST CENTRAL VALLEY AREAS. THE
ONLY CAVEAT TO THIS WOULD BE IF THE MOISTURE WORKING INTO WRN UTAH
OVERNIGHT IS SUFFICIENT TO RAISE RH VALUES ABOVE THE 15 PERCENT
THRESHOLD. WILL MAINTAIN THE FIRE WEATHER WATCH FOR NOW...WITH A
FINAL DECISION ON A RED FLAG WARNING PLANNED FOR THE AFTERNOON
PACKAGE.

RIDGING WILL BUILD IN FROM THE WEST DURING THE LATTER HALF OF THE
WEEK. DRY CONDITIONS AND WARMING TREND ARE EXPECTED THROUGH THE
COMING WEEKEND.

     EVENING FOR FIRE WEATHER ZONES 420-434.
