AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE LAS VEGAS NV
219 PM PDT TUE JUL 23 2013
.SYNOPSIS...THE THREAT OF THUNDERSTORMS WILL CONTINUE THROUGH THE
WEEK AS MONSOON MOISTURE REMAINS OVER THE REGION. FLASH FLOODING
REMAINS A CONCERN...AND MORE ORGANIZED STORM CELLS COULD PRODUCE
ISOLATED SEVERE WINDS IN SOME AREAS. THUNDERSTORM COVERAGE WILL
BEGIN TO DECREASE DURING THE SECOND HALF OF THE WEEK FROM WEST TO
EAST...WITH STORMS MAINLY LIMITED TO SOUTHERN NEVADA AND NORTHWEST
ARIZONA LOCATIONS BY THE WEEKEND.
&&
.SHORT TERM...TODAY THROUGH WEDNESDAY...CLOUDS ASSOCIATED WITH A
POTENTIAL VORTICITY ANOMALY CONTINUE TO SLOWLY PROGRESS NORTH ACROSS
INYO..ESMERALDA...AND LINCOLN COUNTIES EARLY THIS AFTERNOON. THIS
FEATURE WILL BE THE FOCUS OF SHOWER AND THUNDERSTORM DEVELOPMENT
THIS AFTERNOON...PARTICULARLY ON THE NORTH SIDE ACROSS CENTRAL
NEVADA WHERE DEEP MOISTURE ADVECTION IS UNDERWAY. TO THE
SOUTH...DRIER UPPER LEVELS /BUT STILL ABOVE NORMAL PRECIPITABLE
WATER/ ARE NOTED IN SATELLITE AND SOUNDING DATA. WITH THE LACK OF
ANY SYNOPTIC FORCING EXPECT DIURNALLY DRIVEN ISOLATED TO WIDELY
SCATTERED SHOWER AND THUNDERSTORMS TO CONTINUE TO DEVELOP OVER THE
HIGHER TERRAIN. AROUND NOON THE STEERING FLOW WAS TO THE
NORTHWEST...BUT THIS IS EXPECTED TO BECOME MORE SOUTH TO NORTH BY
LATE THIS AFTERNOON. FLASH FLOODING IS THE MAIN THREAT WITH ALL
STORMS TODAY. GUSTY WINDS AND HAIL WILL ALSO BE POSSIBLE WITH
STRONGER STORMS.
FOR WEDNESDAY...THE NORTHWARD MOISTURE ADVECTION CONTINUES NORTH OF
THE CWA...LEAVING LESS MOISTURE AVAILABLE ACROSS OUR FORECAST AREA.
THIS SHOULD LEAD TO A SLIGHT DOWNWARD TREND IN CONVECTION...
ESPECIALLY IN SOUTHWESTERN THIRD OF THE FORECAST AREA. WITH THE
DOWNWARD TREND IN CONVECTION...WILL NOT BE EXTENDING THE FLASH FLOOD
WATCH THROUGH WEDNESDAY AT THIS TIME. THE CURRENT WATCH IS VALID
THROUGH 1100 PM TODAY.
.LONG TERM...THURSDAY THROUGH TUESDAY...MINIMAL CHANGES TO THE
FORECAST. HIGH PRESSURE OVER NORTHERN ARIZONA ON THURSDAY SLOWLY
DRIFTS SOUTH TOWARDS THE NM/AZ/MEXICO BORDER BY SATURDAY. AS THIS
HIGH DRIFTS SOUTH...SOUTHERLY FLOW WILL ALLOW FOR MOISTURE TO STREAM
BACK INTO THE REGION. BOTH THE GFS/ECMWF SHOW A WEAK DISTURBANCE
ROTATING AROUND THE HIGH AND SHOULD KICK OFF MORE CONVECTION ACROSS
THE REGION FRIDAY AND SATURDAY. HOWEVER...BY SUNDAY AN UPPER LEVEL
TROUGH MOVES OVER THE WEST COAST AND THE UPPER LEVEL FLOW WILL TURN
MORE SOUTHWESTERLY TO WESTERLY WHICH WILL ALLOW FOR DRY AIR TO
SPREAD INTO THE REGION FROM WEST TO EAST. BY MONDAY...MOISTURE
SHOULD BE SCOURED OUT OF THE AREA WHICH WILL ALLOW FOR TEMPERATURES
TO INCREASE A FEW DEGREES BY THE MIDDLE OF NEXT WEEK.
&&
.AVIATION...FOR MCCARRAN...STORMS HAVE BEGUN TO FORM OVER THE
MOUNTAINS SURROUNDING THE LAS VEGAS VALLEY AND ARE MOVING IN A
NORTHWESTERLY DIRECTION. THE STEERING FLOW FOR THESE STORMS IS
EXPECTED TO BECOME MORE SOUTHERLY LATER THIS AFTERNOON AND COULD
PUSH THUNDERSTORMS ACROSS THE VALLEY FROM THE MOUNTAINS TO THE
SOUTH. CIGS COULD LOWER TO 6-10K FEET AROUND THUNDERSTORM ACTIVITY.
AT THE TERMINAL WINDS ARE EXPECTED TO BE SOUTHERLY UNDER 12 KTS
OUTSIDE OF ANY THUNDERSTORM OUTFLOW BOUNDARIES IMPACTING THE
AIRPORT. ALL APPROACH CORRIDORS WILL SEE THUNDERSTORMS TODAY.
SIMILAR CONDITIONS ARE EXPECTED WEDNESDAY.
FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...ISOLATED TO SCATTERED THUNDERSTORMS EXPECTED AREAWIDE
ONCE AGAIN TODAY...WITH THE GREATEST COVERAGE EXPECTED NORTH OF LAS
VEGAS. WINDS WILL GENERALLY BE OUT OF THE SOUTH AT AROUND 10
KTS...BUT STRONGER AND ERRATIC NEAR THUNDERSTORMS. CIGS 6-10K FEET
WHERE STORMS DEVELOP OTHERWISE...AOA 14K FEET. SIMILAR CONDITIONS
ARE EXPECTED WEDNESDAY...WITH FEWER THUNDERSTORMS EXPECTED.
