AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
237 PM PDT SUN JUL 16 2006
.SYNOPSIS...MONSOON MOISTURE WAS ON THE INCREASE OVER THE SOUTHERN
AND EASTERN MOJAVE DESERT THIS AFTERNOON...BRINGING ISOLATED
AFTERNOON THUNDERSTORMS. THE MOISTURE WILL PUSH WEST AND NORTH
MONDAY AND TUESDAY...BRINGING THUNDERSTORM CHANCES AND MORE
SEASONABLE TEMPERATURES TO THE REMAINDER OF THE MOJAVE DESERT AND
SOUTHERN GREAT BASIN FOR MUCH OF THE UPCOMING WEEK.
&&
.SHORT TERM...STORMS ARE FIRING ON THE MOGOLLON RIM AGAIN TODAY AND
WILL HEAD OUR WAY IN THE EASTERLY FLOW AROUND THE SOUTHERN PERIPHERY
OF THE MID LEVEL RIDGE. RE-RAISED POPS IN THE SOUTHEAST PART OF THE
CWFA FOR THIS EVENING AND OVERNIGHT...AS ANOTHER EASTERLY WAVE
CROSSING MEXICO MAY PROVIDE ENOUGH FORCING TO KEEP SOME ACTIVITY
GOING ALL NIGHT. MEANWHILE...HIGH HEAT IS STILL A CONCERN.
TEMPERATURES IN THE AREAS ALONG AND SOUTHEAST OF INTERSTATE 15 ARE A
TAD LOWER TODAY...THANKS TO THE SHALLOW MOISTURE SURGE PUSHED UP
OVERNIGHT BY THUNDERSTORM OUTFLOW AND A PASSING EASTERLY WAVE. KLAS
HAS REACHED 111F SO FAR VERSUS 113F YESTERDAY. EXCESSIVE HEAT
WARNING STILL LOOKS GOOD AND WILL KEEP IT GOING UNTIL 7 PM. EXPECT A
LITTLE LESS HEAT TOMORROW AS WELL AS MOISTURE AND CLOUDINESS
CONTINUE TO INCREASE...SO HAVE NOT ISSUED A WATCH FOR TOMORROW.
FORECAST FOR KLAS TOMORROW IS 109F...THREE DEGREES BELOW WARNING
CRITERION. HOWEVER...IT WILL ALSO BE MORE HUMID...WHICH WILL
INCREASE THE DISCOMFORT LEVEL. PLEASE CONTINUE TO BE CAREFUL. VERY
LITTLE CHANGE TO THE FORECAST FOR MONDAY AND TUESDAY AS THE
DEVELOPING SOUTHEASTERLY FLOW AND ASSOCIATED MOISTENING TREND STILL
LOOK ON TARGET. THIS WILL LEAD TO INCREASED THUNDERSTORM COVERAGE
AND SMALLER DIURNAL TEMPERATURE RANGES. POINT TEMPERATURES WILL BE
HIGHLY DEPENDENT ON THE TIMING AND LOCATION OF THUNDERSTORM
DEVELOPMENT NEARBY.
.LONG TERM...ALL SIGNS STILL POINT TO A VERY ACTIVE START TO THE
EXTENDED PERIOD. ALL MODELS PLACE A LOW OFF THE CALIFORNIA COAST
WITH THE CENTER OF THE HIGH WELL OFF TO OUR EAST. THE RESULT WILL BE
A SOUTH TO SOUTHEAST FLOW THAT WILL HAVE ABUNDANT MOISTURE TO TAP
INTO. FOR WEDNESDAY AND THURSDAY KEPT ALL AREAS AT LEAST AT 30 POPS
DURING DAYTIME HOURS. SLIGHTLY BUMPED UP THE NIGHT POPS AS SOME
CONVECTION WILL PROBABLY CONTINUE INTO THE MORNING HOURS. BY FRIDAY
THINGS BECOME MORE CHALLENGING AS THE HIGH STARTS TO BUILD BACK
ACROSS THE AREA. BIG ISSUE WILL BE HOW MUCH OF THE MOISTURE BECOMES
TRAPPED UNDER THE HIGH WHICH WILL HELP TO FIRE OFF STORMS EVER DAY.
CURRENTLY SUSPECT THAT IT WILL BE A SLOW PROCESS TO ENTIRELY DRY OUT
HOWEVER DID NOT MODIFY THE GRIDS IN DAYS SEVEN AND BEYOND. WILL LET
THE MID SHIFT MAKE THAT CALL WITH NEWER MODEL DATA. GFS ALSO SHOWS A
599 CENTERED OVER NORTHERN NEVADA FOR FRIDAY WHICH COULD HELP TO
MAKE TEMPERATURES SOAR IN LOCATIONS THAT REMAIN NEARLY CLOUD FREE.
&&
.AVIATION...TAFS AND TWEBS ADEQUATELY DESCRIBE EXPECTED WEATHER
CONDITIONS FOR AREA TERMINALS. SEE TAFS FOR KLAS... KVGT... KDRA...
KBIH... KDAG... KEED.
AVIATION DISCUSSION NOT UPDATED FOR AMENDED TAFS.
