AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
405 PM MDT SAT JUL 26 2008

.SYNOPSIS...HIGH PRESSURE WILL REMAIN ACROSS THE REGION THROUGH
THE WEEKEND. A WEAK DISTURBANCE WILL MOVE ACROSS UTAH THIS MORNING
INTO THIS AFTERNOON. DRIER AIR WILL MOVE INTO NORTHERN UTAH SUNDAY
INTO MONDAY.

&&

.DISCUSSION...UPPER LEVEL HIGH PRESSURE REMAINS ACROSS THE REGION
THIS AFTERNOON. A WEAK DISTURBANCE CONTINUES TO MOVE ACROSS
PORTIONS OF SOUTHERN UTAH. THIS DISTURBANCE HAS AIDED IN THE
DEVELOPMENT OF A LARGE AREA OF SHOWERS AND THUNDERSTORMS ACROSS
THE SOUTHERN AND EASTERN PORTIONS OF THE CWA. RAINFALL RATES IN
EXCESS OF 2 INCHES HAVE BEEN OCCURRING IN SOME OF THE STORMS.
CAUTION IS ADVISED NEAR ANY SLOT CANYONS AND DRY WASHES ACROSS
SOUTHERN AND EASTERN UTAH.

CONVECTIVE ACTIVITY IS EXPECTED TO GRADUALLY DIMINISH AFTER
SUNSET. ANOTHER ACTIVE DAY IS EXPECTED TOMORROW ACROSS MUCH OF THE
CWA. DEEP MOISTURE IS LIKELY TO REMAIN ALL THE WAY NORTH TO THE
SALT LAKE CITY. A WEAK DISTURBANCE IS FORECAST TO MOVE ACROSS
NORTHERN UTAH DURING THE DAY SUNDAY. THIS MAY HELP TO INCREASE
COVERAGE A BIT MORE THAN TODAY. UPPED THE POPS IN THE FORECAST TO
ACCOUNT FOR THIS. FLASH FLOODING WILL AGAIN BE A CONCERN ACROSS
THE SOUTHERN HALF OF UTAH. MID SHIFT WILL ASSESS THE NEED FOR A
FLASH FLOOD WATCH.

DRIER AIR IS EXPECTED TO MOVE INTO NORTHERN UTAH TUESDAY AND INTO
MUCH OF THE REST OF THE STATE WEDNESDAY. BOTH GFS AND EC ARE
CONSISTENT WITH THIS DRYING TREND. THIS WILL LIKELY KEEP
CONVECTION TIED TO THE TERRAIN FOR MIDWEEK. DECREASED THE POPS
ACROSS VALLEYS LOCATIONS AND A BIT LOWER FOR MOUNTAIN LOCATIONS.
ANOTHER MONSOONAL MOISTURE SURGE IS POSSIBLE NEXT
WEEKEND...OTHERWISE TEMPERATURES WILL REMAIN NEAR TO SLIGHTLY
ABOVE NORMAL THROUGH THE NEXT SEVEN DAYS.

&&

.AVIATION...NORTHWEST WINDS ARE EXPECTED TO SETTLE IN AT THE SLC
TERMINAL FOR THE REMAINDER OF THE AFTERNOON. SOUTHERLY DRAINAGE
WINDS ARE THEN EXPECTED TO DEVELOP BETWEEN 02-03Z.
OTHERWISE...ISOLATED THUNDERSTORMS ARE POSSIBLE ACROSS THE WASATCH
FRONT THROUGH THE EVENING HOURS. ANY THUNDERSTORMS THAT IMPACT THE
TERMINAL WILL LIKELY HAVE GUSTY AND ERRATIC WINDS.

&&

.FIRE WEATHER...MOISTURE IN PLACE ACROSS THE SOUTHERN AND EASTERN
PORTIONS OF THE FIRE DISTRICT WILL PERSIST THROUGH SUNDAY THEN
SLOWLY DRY. WETTING RAINS ARE LIKELY WITH ANY STORMS IN THIS AREA
THROUGH SUNDAY. DRIER AIR IS OVER THE NORTHWEST AND WILL BECOME A
LITTLE MORE MOIST SUNDAY BUT STILL NOT ENOUGH TO BRING MUCH OF A
CHANCE OF WETTING RAIN. ISOLATED THUNDERSTORMS ARE EXPECTED OVER THE
NORTHWEST HOWEVER SO DRY LIGHTNING WILL CONTINUE TO BE A THREAT
ALONG WITH MICROBURST WINDS...MAINLY OVER THE WEST DESERTS AND ALONG
THE WASATCH FRONT. THE THREAT OF ISOLATED MAINLY DRY THUNDERSTORMS
WILL CONTINUE OVER THE NORTH MONDAY THEN OVER THE ENTIRE DISTRICT
TUESDAY. A GENERALLY DRY AIRMASS WILL THEN PERSIST THROUGH THE REST
OF NEXT WEEK.
