NWS Las Vegas, NV wrote its last area forecast discussion before the first event at Aug 5, 8:58 PM PST, 3 hours 2 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LAS VEGAS NV 958 PM PDT MON AUG 5 2013 .SYNOPSIS...A DISTURBANCE MOVING NORTH THROUGH WESTERN ARIZONA WILL BRING A CHANCE OF SHOWERS AND THUNDERSTORMS LATE TONIGHT THROUGH TUESDAY...MAINLY OVER MOHAVE AND FAR SOUTHEAST SAN BERNARDINO COUNTIES. AFTER THIS DISTURBANCE MOVES THROUGH...THE REGION IS EXPECTED TO REMAIN DRY INTO NEXT WEEKEND. TEMPERATURES THIS WEEK WILL BE AROUND NORMAL. && .UPDATE...MID AND HIGH LEVEL MOISTURE CONTINUES TO STREAM INTO THE EASTERN CWA FROM THE SOUTH. THE VAD WIND PROFILE OUT OF YUMA HAS SOUTH WINDS UP TO 25 KTS THROUGH 4000 FEET WITH SURFACE DEWPOINTS IN THE 50S ALONG THE COLORADO RIVER VALLEY. NO SHOWER ACTIVITY WAS NOTED HOWEVER ANYWHERE WITHIN THE FORECAST AREA THIS EVENING AND THE AREA IS EXPECTED TO REMAIN DRY OVERNIGHT. ONGOING FORECAST LOOKS GOOD AT THIS POINT AND NO UPDATES ARE NEEDED. && .PREVIOUS DISCUSSION...305 PM PDT... .SHORT TERM...TONIGHT THROUGH WEDNESDAY NIGHT...MOISTURE HAS BEEN INCREASING TO OUR SOUTH TODAY AS A DISTURBANCE CONTINUES TO PUSH NORTH OUT OF NORTHERN MEXICO. YUMA VAD WIND PROFILE SHOWS SOUTHEAST TO SOUTH WINDS AROUND 15 KTS UP TO 6K FEET THIS AFTERNOON AND DEW POINTS TO OUR SOUTH HAVE ALSO BEEN INCREASING. PW SENSORS IN SOUTHEAST CALIFORNIA AND SOUTHERN ARIZONA HAVE ALSO SHOWN INCREASES THROUGHOUT TODAY. THIS TREND IS EXPECTED TO CONTINUE AS THIS DISTURBANCE TRACKS NORTH TONIGHT AND TUESDAY. NAM12/GFS ARE SHOWING THE 1 INCH PW LINE EXTENDING ACROSS SOUTHERN MOHAVE THROUGH SOUTHERN CLARK AND FAR SOUTHEAST SAN BERNARDINO COUNTIES BY 12Z TUESDAY WITH THE 1.25 INCH LINE JUST ENTERING FAR SOUTHERN MOHAVE COUNTY. ACCORDING TO THE NAM12/GFS ADDITIONAL MOISTURE DOES NOT ADVECT INTO THE REGION...HOWEVER INSTABILITY DOES. LI VALUES BETWEEN -2/-4 AND CAPE VALUES OVER 500 J/KG PLUS THE DISTURBANCE PUSHING NORTH THROUGH WESTERN ARIZONA SHOULD LEAD TO AN INCREASED CHANCE OF THUNDERSTORMS OVER THE FAR SOUTHEAST PORTIONS OF THE CWA TUESDAY. MOISTURE IS NOT SIGNIFICANTLY DEEP...BUT ISOLATED FLASH FLOODING COULD BE A CONCERN. STRONG WINDS AND HAIL MAY ALSO ACCOMPANY THESE STORMS DUE TO THE MUCH DRIER MID LEVEL AIR POTENTIALLY ADVECTING INTO THE AREA. ITS POSSIBLE SOME CU MAY DEVELOP OVER THE SIERRA...BUT MOISTURE DOES NOT LOOK TO BE DEEP ENOUGH TO GENERATE ANY STORMS FURTHER SOUTH THAN MONO COUNTY. AN UPPER LOW OFF THE NORTHERN CA COAST WILL MOVE INLAND LATE TUESDAY AND THE DRIER SOUTHWEST FLOW WILL HELP TO PUSH ANY MOISTURE TO THE EAST...SO WEDNESDAY LOOKS TO BE DRY AREAWIDE. TEMPERATURES WILL RUN CLOSE TO NORMAL FOR THIS TIME OF YEAR. .LONG TERM...THURSDAY THROUGH MONDAY...A TROUGH OF LOW PRESSURE JUST OFF THE COAST WILL MOVE VERY LITTLE THROUGH THE PERIOD AND KEEP THE FORECAST AREA UNDER A DRY AND STABLE SOUTHWESTERLY FLOW. THE ONLY FORECAST CONCERN WILL BE WIND SPEEDS ON THURSDAY AND FRIDAY...WHICH ARE CURRENTLY FORECAST TO BE JUST UNDER SPEEDS THAT WOULD RESULT IN CRITICAL FIRE WEATHER CONDITIONS. IF BOUNDARY LAYER WINDS LOOK TO BE ANY STRONGER THAN CURRENTLY EXPECTED OVER THE NEXT COUPLE DAYS...FIRE WEATHER PRODUCTS MAY BE NEEDED. SLIGHTLY BELOW NORMAL TEMPERATURES CAN BE EXPECTED THROUGH THE PERIOD. && .AVIATION...FOR MCCARRAN...SOUTHWEST WIND BETWEEN 15-25 KTS INTO THIS EVENING BEFORE DIMINISHING TO AROUND 10 KTS AFTER 03Z. WINDS TUESDAY ARE FORECAST TO TURN MORE 160-180 DEGS AFTER 16Z WITH SPEEDS GENERALLY BETWEEN 8-10 KTS. BKN CLOUDS AOA 20K FEET TONIGHT WITH FEW-SCT CLOUDS AROUND 14K FEET AFTER 08Z TONIGHT THROUGH TUESDAY. SCATTERED THUNDERSTORMS ARE POSSIBLE IN THE PEACH SPRINGS AND MORMON MESA CORRIDORS TUESDAY. FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST CALIFORNIA...BKN CLOUDS AOA 20K FEET OVER THE EASTERN HALF OF THE CWA TONIGHT WITH GENERALLY CLEAR SKIES ELSEWHERE. ISOLATED TO SCATTERED THUNDERSTORMS ARE FORECAST OVER PORTIONS OF MOHAVE...SOUTHEAST SAN BERNARDINO AND FAR SOUTHERN CLARK COUNTY TUESDAY WITH CIGS POSSIBLY LOWERING TO AROUND 10K FEET.
