AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
1033 AM PDT WED AUG 9 2006

.SYNOPSIS...HIGH PRESSURE TO OUR EAST HAS STARTED TO BRING AN
INCREASE IN MOISTURE TO THE MOJAVE DESERT AND SOUTHERN GREAT BASIN
TODAY AND WILL DO SO FOR THE NEXT TWO TO THREE DAYS. THIS WILL
RESULT IN AFTERNOON AND EVENING THUNDERSTORMS OVER PARTS OF
NORTHWEST ARIZONA AND SOUTHEAST NEVADA THROUGH THE END OF THE
WEEK...ESPECIALLY OVER MOUNTAINS.
&&

.UPDATE...CURRENT FORECAST LOOKS ON TRACK AND PLAN ON UPDATE. ONE
INCH IN PW INCREASE IN MOHAVE AND SOUTHERN CLARK COUNTY THE LAS 24
HOURS QUITE IMPRESSIVE. ITEM THAT CONCERNS ME THE MOST WOULD BE
HEAVY RAIN FROM ANY THUNDERSTORMS IN TODAYS JUICY AIR.
&&

.PREVIOUS DISCUSSION...217 AM PDT WED AUG 9 2006...SHORT
TERM...TODAYS CHALLENGE IS TO FIGURE OUT WHERE AND WHEN CONVECTION
WILL FIRE IN THE SHORT TERM AS MONSOONAL MOISTURE HAS RETURNED OVER
THE SOUTHEAST THIRD OF THE CWA. CURRENTLY SOME PESKY WEAK CONVECTION
IS TAKING PLACE FROM NEAR MESQUITE DOWN THROUGH MOHAVE COUNTY. WHILE
I DONT REALLY SEE ANY DISCERNIBLE WAVE ON WATER VAPOR...IT IS IN
THE RIGHT REAR QUADRANT OF THE UPPER JET. EXPECT THIS TO WAIN AS THE
SPEED MAX MOVES DOWNSTREAM LATER THIS MORNING...BUT CONVECTION WILL
LIKELY REDEVELOP THIS AFTERNOON OVER THE HIGHER TERRAIN GENERALLY
SOUTH AND EAST OF THE LAS VEGAS VALLEY.

AFTER TODAY MODELS GENERALLY SHOW PRECIPITABLE WATER SLOWLY
INCREASING...AGAIN MAINLY CONFINED TO THE SOUTHEAST HALF OF THE
CWA...SO DAILY AFTERNOON AND EVENING THUNDERSTORMS OVER THE HIGHER
TERRAIN IS TO BE EXPECTED. BY FRIDAY ANOTHER WAVE BEGINS TO DROP
DOWN THE BACK SIDE OF THE WEST COAST TROF AND SHOULD BEGIN TO USHER
DRIER AIR IN TOWARDS THE WEEKEND.
&&

.LONG TERM...NO MAJOR CHANGES TO FORECAST IN THE EXTENDED.

A LARGE RIDGE SITTING TO OUR WEST COMBINED WITH A SLOW-MOVING TROUGH
NEAR THE CALIFORNIA COAST WILL RESULT IN DRY SOUTHWEST FLOW OVER THE
ENTIRE CWA DURING THE PERIOD. HAVE LEFT 20-30 POPS OVER MOHAVE
COUNTY DURING THE WEEKEND WITH MARGINAL MOISTURE STILL PRESENT FOR
CONVECTION...THEN HAVE TRENDED POPS DOWN AS MOISTURE IS FLUSHED FROM
THE EASTERN EDGE OF THE CWA.  TEMPERATURES WILL REMAIN TO HOVER AT
AND JUST BELOW NORMAL WITH LITTLE DAY TO DAY CHANGE EXPECTED.

&&

.AVIATION...TAFS AND TWEBS ADEQUATELY DESCRIBE EXPECTED WEATHER
CONDITIONS FOR AREA TERMINALS. SEE TAFS FOR KLAS... KVGT... KDRA...
KBIH... KDAG... KEED... FOR DETAILS.

AVIATION DISCUSSION NOT UPDATED FOR AMENDED TAFS.
