AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1030 AM MDT WED AUG 1 2007

.SYNOPSIS...UPPER LEVEL RIDGE WILL REMAIN CENTERED OVER COLORADO
THROUGH THURSDAY EVENING...WITH A SERIES OF WEAK MID LEVEL
DISTURBANCES PIVOTING AROUND RIDGE.  VERY MOIST AIRMASS WILL REMAIN
OVER THE INTERMOUNTAIN REGION THROUGH THURSDAY.

&&

.DISCUSSION...A WEAK IMPULSE OVER WEST CENTRAL UTAH IS CONTRIBUTING
TO MORNING SHOWERS OVER NORTHWEST AND WEST CENTRAL UTAH TODAY. THIS
WAVE AND ASSOCIATED SHOWERS AND EXPECTED AFTERNOON THUNDERSTORMS
WILL SLIDE NORTH AND EAST THROUGH THIS AFTERNOON.
MEANWHILE...SIGNIFICANT MIDLEVEL CLOUD COVER IS PRESENT OVER
PORTIONS OF WESTERN AND SOUTHERN UTAH THIS MORNING. ONCE THESE
CLOUDS THIN OUT IN THE AFTERNOON...EXPECT TO SEE SCATTERED TO
NUMEROUS SHOWERS AND THUNDERSTORMS DEVELOP OVER THE AREA. WITH
SIGNIFICANT MOISTURE OVER THE CWA TODAY.../PRECIPITABLE WATER
GENERALLY AN INCH TO AN INCH AND A HALF OVER MOST OF THE
AREA/...EXPECT ANY THUNDERSTORMS THAT DEVELOP TO HAVE THE POTENTIAL
FOR HEAVY RAIN.

MORE OF THE SAME CAN BE EXPECTED TOMORROW...WITH MOISTURE REMAINING
OVER THE AREA AND THE SHORTWAVE DISTURBANCE THAT IS CURRENTLY OVER
SOUTHERN NEVADA LOOKING TO IMPACT NORTHWEST AND WEST CENTRAL UTAH
AGAIN IN THE MORNING. A SOUTHWESTERLY FLOW ON FRIDAY WILL DRAW DRIER
AIR INTO WESTERN UTAH...BUT CONVECTION IS STILL A GOOD BET FOR MOST
OF THE MOUNTAINS AND EASTERN PORTIONS. DRIER AIR CONTINUES TO WORK
ITS WAY INTO WESTERN AND CENTRAL UTAH THIS WEEKEND BEFORE ANOTHER
SURGE BRINGS ADDITIONAL MOISTURE INTO SOUTHERN AND EASTERN UTAH FOR
THE EARLY PART OF NEXT WEEK.

CURRENT PACKAGE LOOKS GOOD. NO UPDATES THIS MORNING.

&&

.AVIATION...SOUTHERLY DRAINAGE WINDS WILL PREVAIL INTO THE MORNING.
THE SHIFT TO THE NORTHWESTERLY BREEZE IS EXPECTED AROUND 19Z...CLOSE
TO THE USUAL TIME. OUTFLOW FROM NEARBY THUNDERSTORMS WILL LIKELY
CAUSE PERIODS OF GUSTY WINDS WITH ERRATIC DIRECTIONS...PRIMARILY
DURING THE LATE AFTERNOON AND EARLY EVENING. THERE IS A 30 PERCENT
CHANCE THAT A THUNDERSTORM WILL DIRECTLY IMPACT THE SLC TERMINAL
TODAY.

&&

.FIRE WEATHER...A MOIST AIRMASS WILL REMAIN IN PLACE WITH HIGHER
HUMIDITIES AND SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS
ACROSS THE DISTRICT. MOST STORMS TODAY WILL PRODUCE WETTING RAINS.
SOME DRYING IS POSSIBLE STARTING FRIDAY AND CONTINUING OVER THE
WEEKEND BUT AFTERNOON AND EVENING CONVECTION SHOULD STILL OCCUR
THROUGH SUNDAY.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...NONE.
WY...NONE.
