AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
232 PM PDT TUE JUL 16 2013

.SYNOPSIS...THUNDERSTORM CHANCES WILL BE LIMITED TO EASTERN LINCOLN
AND MOHAVE COUNTIES THROUGH THURSDAY...WITH DRY WEATHER AND NEAR
NORMAL TEMPERATURES EXPECTED ELSEWHERE. MOISTURE WILL RETURN FRIDAY
THROUGH THE WEEKEND...WITH INCREASING THUNDERSTORM CHANCES AREAWIDE
AND A RISK OF LOCALLY HEAVY RAIN.
&&

.SHORT TERM...SATELLITE LOOP SHOWED CUMULUS CLOUDS LIMITED TO CLARK
LINCOLN AND MOHAVE COUNTIES THIS AFTERNOON...WITH THUNDERSTORMS
CONFINED TO NORTHERN AND EASTERN MOHAVE COUNTIES. CIRRUS BLANKETED
MOST OF THE REST OF THE CWA...WITH THE THICKEST CIRRUS EAST OF A
LINE FROM THE MOJAVE NATIONAL PRESERVE TO ELGIN AS OF 130 PM. SMOKE
FROM THE MOUNTAIN FIRE NEAR IDYLLWILD WAS ALSO ADVECTING NORTH
ACROSS SAN BERNARDINO COUNTY. COARSER MODELS DID A PRETTY GOOD JOB
OF OUTLINING THE CONVECTION AREA TODAY...AND TRENDS SUGGEST EVEN
LESS COVERAGE TOMORROW. ONE POTENTIAL CONCERN IS NORTHEAST MID LEVEL
FLOW OVER SOUTHERN MOHAVE COUNTY WHICH COULD PUSH STORMS OFF THE
HIGHER TERRAIN INTO THE DESERT IN THE EVENING. SMOKE FROM THE
MOUNTAIN FIRE WILL BE A CONCERN OVERNIGHT AND IN THE MORNING AS THE
PLUME DESCENDS...AND INCLUDED SMOKE IN THE GRIDS FOR A LARGE PART OF
SAN BERNARDINO COUNTY. TEMPERATURES SHOULD CHANGE LITTLE FROM TODAY
TO TOMORROW.

.LONG TERM...THURSDAY THROUGH MONDAY...HIGH PRESSURE WILL REMAIN
CENTERED ROUGHLY OVER THE NEVADA/UTAH STATE LINE THURSDAY WITH AN
INVERTED TROUGH MAKING ITS WAY WESTWARD ACROSS NORTHERN MEXICO. THIS
TROUGH WILL HELP TO PUSH THE HIGH CENTER FURTHER WEST ON FRIDAY WITH
THE HIGH BECOMING CENTERED OVER NORTHERN NEVADA. MODELS STILL
INDICATE THAT THE MOISTURE BOUNDARY WILL REMAIN OVER THE FAR
SOUTHEAST PORTIONS OF THE CWA WITH MAINLY MOHAVE COUNTY SEEING THE
BEST THUNDERSTORM CHANCES. STILL LEFT IN SOME MENTION OF
THUNDERSTORMS OVER THE SOUTHERN NEVADA MOUNTAINS AND PORTIONS OF
LINCOLN COUNTY AND EASTERN SAN BERNARDINO COUNTIES. HOWEVER...ANY
THUNDERSTORMS WEST OF THE COLORADO RIVER WILL LIKELY REMAIN CONFINED
TO THE HIGHER TERRAIN. BY SATURDAY...THE HIGH IS FORECAST TO BE
CENTERED OVER WESTERN NEVADA WHILE THE INVERTED TROUGH WILL BE
POSITIONED JUST OFF THE WESTERN MEXICO COAST. THIS WILL TURN THE
FLOW MORE EAST TO SOUTHEAST WHICH WILL OPEN THE DOOR FOR MOISTURE TO
ADVECT INTO THE REGION. PW VALUES WILL START TO INCREASE OVER THE
SOUTHEAST PORTIONS OF THE CWA ALONG WITH GREATER INSTABILITY. THIS
WILL LEAD TO MORE SCATTERED THUNDERSTORMS FOR THE SOUTHEAST PORTIONS
OF THE CWA...INCLUDING EASTERN SAN BERNARDINO...CLARK...LINCOLN AND
MOHAVE COUNTIES. SUNDAY AND MONDAY LOOK TO SEE THE MOST THUNDERSTORM
COVERAGE AS MOISTURE CONTINUES TO ADVECT INTO THE REGION. GREATER
INSTABILITY...HIGH DEWPOINTS AND GENERALLY LIGHT EASTERLY FLOW WILL
LEAD TO INCREASED THUNDERSTORM COVERAGE AND THE GREATER POTENTIAL OF
HEAVY RAIN PRODUCING STORMS. IT LOOKS LIKE THE MAJORITY OF THE CWA
WILL SEE AT LEAST A CHANCE OF THUNDERSTORMS BOTH DAYS AND HAVE
INCREASED POPS TO REFLECT THIS. NOTHING REALLY POINTS TO ANYTHING
SCOURING OUT THE MOISTURE DURING THE EXTENDED PERIOD SO IT LOOKS
LIKE THUNDERSTORMS WILL REMAIN IN THE FORECAST TO MUCH OF THE AREA
THROUGH AT LEAST THE MIDDLE PART OF NEXT WEEK. TEMPERATURES WILL BE
CLOSE TO NORMAL THURSDAY AND FRIDAY BUT WILL LIKELY DROP A FEW
DEGREES BY THE WEEKEND AND EARLY NEXT WEEK DUE TO THE INCREASED
MOISTURE AND CLOUD COVER.
&&

.AVIATION...FOR MCCARRAN...THERE WILL BE A PERIOD OF SOUTHEASTERLY
WINDS IN THE LATE MORNING AND EARLY AFTERNOON EACH DAY THROUGH
THURSDAY...WITH A MORE PRONOUNCED EAST WIND POSSIBLE ON THURSDAY.
LATE AFTERNOON AND EVENING WINDS WILL CONTINUE TO BE SOUTHERLY OR
SOUTHWESTERLY WITH GUSTS UP TO 20 KNOTS WEDNESDAY AND LIGHTER SPEEDS
THURSDAY. THERE WILL BE ISOLATED THUNDERSTORMS IN THE PEACH SPRINGS
AND MORMON MESA CORRIDORS THROUGH THURSDAY...THEN THUNDERSTORM
CHANCES WILL INCREASE AREAWIDE OVER THE WEEKEND.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...THUNDERSTORM CHANCES WILL BE CONFINED TO EASTERN
LINCOLN AND MOHAVE COUNTIES THROUGH THURSDAY...THEN PUSH BACK WEST
ACROSS THE ENTIRE AREA OVER THE WEEKEND. OUTSIDE OF THUNDERSTORMS
OPERATIONALLY SIGNIFICANT CLOUDS AND WINDS ARE NOT EXPECTED.
