AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
744 PM PDT TUE OCT 24 2006

.SYNOPSIS...DRY NORTHWEST FLOW ALOFT TO MOVE OVER THE AREA TONIGHT
RESULTING IN LOCALLY BREEZY CONDITIONS WEDNESDAY AND THURSDAY WITH
BELOW NORMAL TEMPERATURES.
&&

.UPDATE...SATELLITE SHOWS UPPER LOW CONTINUING TO TREK EAST OVER
NORTHERN MOHAVE COUNTY. WARM CONVEYOR BELT AND ASSOCIATED DEEP
CLOUDS/PRECIP CHANCES HAVE EXITED OUR AREA. WRAPAROUND CLOUDS OVER
LINCOLN...CLARK...AND MOHAVE COUNTIES ARE THINNING OUT AS LARGE
SCALE DESCENT TAKES OVER. NEXT NORTHERN STREAM DISTURBANCE KICKING
FEW CIRRUS AND MOUNTAIN INDUCED ALTOCUMULUS OVER THE FAR NORTHWEST
CWFA...WITH CLEAR SKIES IN BETWEEN THE TWO SYSTEMS. WILL UPDATE ZONE
PACKAGE SHORTLY FOR CURRENT TRENDS...WITH NO CHANGES ANTICIPATED
BEYOND THE FIRST PERIOD.
&&

.PREV DISCUSSION...
320 PM PDT TUE OCT 24 2006

.SHORT TERM...UPPER LOW SHIFTING EAST THIS AFTERNOON WITH EXPECTED
DRYING TAKING PLACE OVER THE SOUTHEAST PORTION OF THE CWA. MAIN
PRECIPITATION BAND WHICH HAS BEEN OVER MOHAVE COUNTY DURING THE DAY
RAPIDLY PUSHING EAST WITH ONLY SCATTERED SHOWERS/ISOLATED
THUNDERSTORMS EXPECTED THIS EVENING BEFORE NORTHWEST FLOW ALOFT
ASSOCIATED WITH PACNW SHORTWAVE KICKS IN AND DRIES AREA OUT BY
WEDNESDAY. COLD FRONT ASSOCIATED WITH NORTHERN SHORT WAVE TO PUSH
INTO THE NORTHERN PORTION OF THE CWA AROUND 12Z AND EXPECTED ACROSS
THE KLAS VALLEY AROUND 18Z WEDNESDAY. INCREASED SURFACE PRESSURE/
THERMAL GRADIENTS TO KICK WINDS INTO THE BREEZY/WINDY CATEGORY MOST
AREAS AS FRONT PASSES. ALTHOUGH LOCALIZED WIND GUSTS MAY REACH
ADVISORY CRITERIA...OVERALL WIND SPEEDS SHOULD STAY BELOW CRITERIA
ON WEDNESDAY. EXCEPTION BEING THE LAKE MEAD NRA WHERE NORTH/SOUTH
CHANNELS WILL LIKELY ENHANCE NORTH FLOW AND WILL ISSUE LAKE WIND
ADVISORY FOR THIS AREA. EVE/MID SHIFTS HOWEVER WILL NEED TO WATCH
GRADIENTS OVERNIGHT TO SEE IF BROADER ADVISORY IS NEEDED. BY 12Z
THURSDAY FLOW ALOFT TO BECOME MORE NORTHERLY AS SHORT WAVE TROUGH
PUSHING EAST OUT OF THE SOUTHERN ROCKIES AND SHORT WAVE RIDGE BEGINS
TO BUILD OVER THE AREA FOR CONTINUED DRY CONDITIONS. ALTHOUGH NORTH
WINDS WILL STILL BE SEEN ON THURSDAY ONLY AREA OF CONCERN WILL BE
THE COLORADO RIVER VALLEY AND WILL KEEP BREEZY IN THE FORECAST.
TEMPERATURES NEXT SEVERAL DAYS TO BE A CHALLENGE. CLOUDS/SHOWERS
OVER THE SOUTHEAST TODAY DID NOT ALLOW FOR FULL HEATING POTENTIAL.
THUS WITH COLD AIR ADVECTION EXPECTED ON WEDNESDAY...TEMPS WILL
ACTUALLY WARM ACROSS THE SOUTHEAST DUE TO MORE SUN...WHILE COOLING
OVER THE NORTH. FURTHER COOLING THEN EXPECTED ON THURSDAY AS THE
COOL AIR ADVECTION CONTINUES...BEFORE WARMING INTO THE LONG
TERM.

.LONG TERM...NOT TOO MUCH CHANGE TO PREVIOUS FORECAST WITH DRY
CONDITIONS EXPECTED FRIDAY THROUGH THE FIRST HALF OF NEXT WEEK. A
BROAD AND FLAT RIDGE OVER THE WRN CONUS/ERN PAC ON FRIDAY WILL
SLOWLY SLIDE EAST DURING THE PERIOD AS UPR LVL WINDS OUT OF THE NW
SLOWLY BACK TO THE SW AS RIDGE MIGRATES...KEEPING US IN DRY FLOW. ON
MONDAY A MINOR SHORTWAVE WILL MOVE ACROSS THE CWA...BUT EFFECTS WILL
BE MINIMAL WITH NO MOISTURE TO WORK WITH.  NOT MUCH CHANGE TO
PREVIOUS NIGHTS TEMP GRIDS WITH MODELS STILL INDICATING WEAK NW FLOW
DURING THE PERIOD. WHICH WILL HELP MITIGATE QUICK TEMPERATURE
RECOVERY FRIDAY AND SATURDAY...BUT SHOULD BE BACK TO NORMAL BY THE
END OF THE WEEKEND. ALL IN ALL THE DRY/BENIGN SOLUTION SEEMS MOST
LIKELY...HOWEVER CONFIDENCE DROPS SIGNIFICANTLY BEYOND SUNDAY WITH
LARGE MODEL SPREAD AND RUN TO RUN DIFFERENCES.

.AVIATION...WIDELY SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS WILL
CONTINUE ACROSS THE PEACH SPRINGS CORRIDOR THROUGH THIS EVENING.
TOMORROW...SKIES WILL MUCH MORE CLEAR...BUT SURFACE WINDS WILL BE
STRONGER OUT OF THE N WITH SUSTAINED VALUES NEAR 20KTS WITH HIGHER
GUSTS BY 20Z. TAFS AND TWEBS ADEQUATELY DESCRIBE EXPECTED WEATHER
CONDITIONS FOR AREA TERMINALS. SEE TAFS FOR KLAS...KVGT...KDRA...
