AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
400 AM PDT WED JUL 13 2011

.SYNOPSIS...A LOW PRESSURE SYSTEM ALONG THE WEST COAST WILL BRING A
DRY SOUTHWEST FLOW TO THE ENTIRE REGION INTO THE WEEKEND.
TEMPERATURES ARE EXPECTED TO BE BELOW NORMAL INTO SATURDAY WITH
BREEZY CONDITIONS DURING THE AFTERNOONS.
&&

.SHORT TERM...TODAY THROUGH FRIDAY NIGHT...WATER VAPOR IMAGERY
SHOWED A CLOSED UPPER LOW CENTERED NEAR SEATTLE WITH THE AXIS OF THE
BROAD TROUGH EXTENDING DOWN THE WEST COAST. THE MEAN TROUGH IS
FORECAST TO HOLD ITS POSITION THROUGH FRIDAY WITH DRY STABLE
SOUTHWEST FLOW ACROSS THE ENTIRE REGION. THE MAIN WEATHER PROBLEM
WILL BE GUSTY SOUTH TO SOUTHWEST WINDS EACH AFTERNOON AND EVENING.
OBSERVATIONS ACROSS CENTRAL NYE AND WESTERN LINCOLN COUNTIES TUESDAY
REVEALED WINDS WERE ABLE TO GUST OVER 35 MPH AT NUMEROUS AUTOMATED
SENSORS AND THE LATEST NAM INDICATES SPEEDS SHOULD BE SLIGHTLY
HIGHER THIS AFTERNOON. DECIDED TO ISSUE A RED FLAG WARNING IN
COORDINATION WITH WFO ELKO FOR THESE ZONES WITH LOW RH VALUES AND
FINE FUELS DRY TO VERY DRY...ESPECIALLY IN THE DESERTS OF CENTRAL
NYE AND WESTERN LINCOLN COUNTIES. THE NAM INDICATES WIND SPEEDS
SHOULD TREND DOWNWARD SLIGHTLY THURSDAY AND FRIDAY. ONE OTHER THING
TO WATCH IS THAT THERE WILL LIKELY BE SOME CUMULUS DEVELOPMENT OVER
THE SOUTHERN SIERRA AND OWENS VALLEY EACH AFTERNOON AND ISOLATED
THUNDERSTORMS COULD DEVELOP THURSDAY AND FRIDAY. THE NAM INDICATES
MORE INSTABILITY NEAR BISHOP THAN THE GFS SOLUTION BUT MORE
FAVORABLE CONDITIONS FOR CONVECTION ARE INDICATED FARTHER NORTH.
TEMPERATURES WILL CONTINUE TO TREND DOWNWARD AND THE FORECAST VALUES
ARE IN LINE WITH THE LATEST MOS GUIDANCE.

.LONG TERM...SATURDAY THROUGH TUESDAY...NOT MUCH DIFFERENT TO
FORECAST WITH THIS PACKAGE. MODELS STILL HAVE TROUGHING OFF THE WEST
COAST AND HIGH PRESSURE OVER THE CENTRAL STATES WITH OUR AREA UNDER
SOUTHWEST FLOW TO START OUT WITH SATURDAY. THE HIGH IS FORECAST TO
GRADUALLY MOVE WEST AND HAVE THE FLOW GRADUALLY BACK TO THE SOUTH
AND THEN VEER BACK TO THE SOUTHWEST BY MIDWEEK. MOISTURE IS ALSO
EXPECTED TO WORK ITS WAY INTO THE EASTERN PART OF THE CWA EARLY NEXT
WEEK. MODELS CONTINUE TO SHOW THE BEST MOISTURE INCREASE IN MOHAVE
COUNTY WHILE THE REST OF THE CWA WILL AT LEAST SEE INCREASED
DEWPOINTS. HAVE KEPT THE AFTERNOON AND EVENING THUNDERSTORMS IN
MOHAVE COUNTY AS THERE IS NO INDICATION NOW THE MOISTURE WILL BE
PUSHED FURTHER WEST. MODELS ARE ALSO SUGGESTING A RETURN TO
SOUTHWEST FLOW MIGHT BE ON TAP MIDWEEK. THERE ARE SIGNIFICANT
DIFFERENCES IN HANDLING THE NEXT PACIFIC NORTHWEST TROUGH. THE ECMWF
WANTS TO PROGRESS IT INTO THE NORTHWEST SATES WHILE THE GFS AND GEM
KEEP IT ALONG THE COAST. EITHER SCENARIO WOULD LEAD TO PUSHING THE
MOISTURE BACK OUT OF THE AREA.
&&

.AVIATION...FOR MCCARRAN...
6 TO 10 KNOT SOUTHWEST WINDS WILL GIVE WAY TO MORE SOUTHEASTERLY
WINDS AROUND 15Z. THERE MAY BE A BIT OF A MORE EASTWARD VARIABLE
COMPONENT IN THE WINDS LATE IN THE MORNING BUT THAT SHOULD GENERALLY
BE LIMITED AND BELOW 12 KNOTS. STRONGER 10 TO 15 KT SOUTHWESTERLIES
WILL SET UP AROUND 19Z WITH GUSTS IN THE 20 TO 25 KT RANGE. SKIES
ARE EXPECTED TO BE CLEAR THROUGH THE PERIOD.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...TYPICAL DIURNAL WIND PATTERNS WITH CLEAR SKIES CAN BE
EXPECTED THROUGH MID MORNING. GENERALLY SOUTH TO SOUTHWEST WINDS
WILL PICK UP IN THE 16 TO 19Z RANGE...DEPENDING ON THE
TERMINAL...WITH GUSTS OF 15 TO 25 KNOTS LASTING THROUGH THE
AFTERNOON. WINDS IN WESTERN SAN BERNARDINO COUNTY WILL LIKELY BE
MORE WESTERLY. SKIES ARE EXPECTED TO BE CLEAR THROUGH THE PERIOD.
&&

.FIRE WEATHER...A BROAD AREA OF LOW PRESSURE IS FORECAST TO HOLD
ALONG THE WEST COAST THROUGH THE REST OF THE WEEK. THIS PATTERN WILL
PRODUCE GUSTY SOUTH TO SOUTHWEST WINDS AND LOW RELATIVE HUMIDITY
DURING THE AFTERNOON AND EVENING HOURS EACH DAY THROUGH AT LEAST
SATURDAY. GUSTS OVER 35 MPH WERE REPORTED BY NUMEROUS SITES TUESDAY
AFTERNOON OVER THE DESERTS OF SOUTH CENTRAL NEVADA AND WIND SPEEDS
SHOULD BE SLIGHTLY HIGHER THIS AFTERNOON THROUGH EARLY EVENING. A
RED FLAG WARNING IS IN EFFECT FOR NV FIRE WEATHER ZONES 460>462 TO
ADDRESS THIS.
&&
