NWS Las Vegas, NV wrote its last area forecast discussion before the first event at Sep 27, 2:15 PM PST, 27 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LAS VEGAS NV 315 PM PDT SAT SEP 27 2014 .SYNOPSIS...AN UPPER LOW WILL SLOWLY SHIFT EAST ACROSS THE GREAT BASIN TONIGHT AND SUNDAY. SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS ARE POSSIBLE UNDER THIS LOW AND WILL MOSTLY AFFECT INYO COUNTY AND SOUTHERN NEVADA. MUCH COOLER TEMPERATURES CAN BE EXPECTED SUNDAY AND MONDAY. THE REGION WILL LIE UNDER A DRY NORTHWEST FLOW FOR THE REMAINDER OF THE WEEK WITH TEMPERATURES WARMING BACK TO SEASONAL NORMALS. && .DISCUSSION... LINE OF THUNDERSTORMS THAT BROUGHT HEAVY RAIN TO PARTS OF SOUTHWEST UTAH AND NORTHWEST ARIZONA EARLIER TODAY HAS SHIFTED EAST INTO CENTRAL ARIZONA. THE FLASH FLOOD WATCH FOR MOHAVE COUNTY HAS BEEN CANCELLED. THE HEAVY RAINFALL DID LEAD TO A SIGNIFICANT INCREASE IN FLOWS ON THE BEAVER DAM WASH WHICH PROMPTED THE EVACUATION OF FOLKS LIVING NEAR THE WASH. JUST CONTACTED MOHAVE COUNTY EOC AND THE EVACUATIONS HAVE BEEN LIFTED. USGS STREAM GAGES ON THE MUDDY RIVER AND BEAVER DAM INDICATE A DOWNWARD TREND. WORST LOOKS TO HAVE PASSED SO THE PLAN WILL BE TO CANCEL THE FLOOD WARNINGS AND REPLACE WITH FLOOD ADVISORIES TO ALLOW FLOWS TO CONTINUE TO RECEDE. SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS HAVE DEVELOPED THIS AFTERNOON UNDER THE COLD UPPER LOW OVER INYO, ESMERALDA AND NYE COUNTIES. SOME OF THIS ACTIVITY SHOULD PERSIST THROUGH THE NIGHT.
