AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LAS VEGAS NV 328 PM PDT FRI JUL 16 2004 .SYNOPSIS...A SLOW DECREASE IN MONSOON MOISTURE WILL OCCUR OVER THE WEEKEND AND INTO EARLY NEXT WEEK. THIS DRYING WILL BE BROUGHT ON BY A SOUTHWEST FLOW THAT WILL DEVELOP AS A LOW PRESSURE SYSTEM APPROACHES THE WEST COAST. HOWEVER...ENOUGH RESIDUAL MOISTURE WILL REMAIN THAT ONE CAN NOT RULE OUT ISOLATED TO SCATTERED THUNDERSTORMS MAINLY OVER THE MOUNTAINS. && .SHORT TERM...SIMILAR TO YESTERDAY STORMS ERUPTED OVER THE MOUNTAINS OF CLARK COUNTY EARLY THEN HAVE SINCE MOVED NORTH INTO CENTRAL NYE AND LINCOLN COUNTIES. STORMS SHOULD CONTINUE UP ACROSS SOUTH CENTRAL NEVADA WELL INTO THE NIGHT AS MODELS KEEP A WEAK VORTICITY LOBE CIRCULATING AROUND NORTHERN LINCOLN COUNTY. NEXT AREA OF CONCERN DEALS WITH STORMS MOVING OUT OF YAVAPAI/COCONINO COUNTIES INTO MOHAVE COUNTY. PRESENTLY...STRONGEST STORMS ARE OVER CENTRAL MOHAVE COUNTY WITH MOVEMENT TOWARD THE NORTHWEST. STORM OUTFLOWS AND PROPAGATION FROM ARIZONA STORMS SHOULD FIRE STORMS LATER THIS AFTERNOON AND THROUGH THIS EVENING ACROSS THE LAKE MEAD NRA...CLARK AND ERN SAN BERNARDINO COUNTY. HEAVY RAIN STILL A CONCERN FROM STORMS BUT AGAIN BELIEF AREAS WILL BE LOCALIZED THAT FLASH FLOOD WATCH NOT NEEDED. ETA MODEL SHOWING WEAK DISTURBANCE FROM DECAYING COMPLEXES OVER SOUTH CENTRAL ARIZONA DESERTS THIS EVENING WILL BE MOVING NORTHWARD INTO NORTHWEST ARIZONA OVERNIGHT SO POTENTIAL OF NOCTURNAL STORMS POSSIBLE ACROSS MOHAVE COUNTY. MODELS IN AGREEMENT THAT AS UPPER TROUGH APPROACHES THE PACIFIC NORTHWEST COAST LATE SUNDAY AFTERNOON THAT UPPER FLOW BECOMES MORE SOUTHWESTERLY AND SLOW DRYING WILL TAKE PLACE. ENOUGH RESIDUAL MOISTURE WILL STILL BE AROUND THAT ISOLATED THUNDERSTORMS STILL POSSIBLE OVER AT LEAST THE MOUNTAINS AND MOHAVE COUNTY SUNDAY AND MONDAY. && .LONG TERM...SOME KNOCK DOWN OF RIDGE STILL EXPECTED FROM PAC NORTHWEST TROUGH AND SOUTHWEST FLOW WILL DECREASE CONVECTION. IN THE FAR EXTENDED...THURSDAY AND FRIDAY...THERE APPEARS TO BE TWO CONTENDING ITEMS TO WATCH. THE GFS HAS A WEAK INVERTED TROUGH MOVING WEST OVER MEXICO AND OVER THE GULF OF CA BY THURSDAY. A PRECURSOR TO ANOTHER MOISTURE SURGE? WHILE AT THE SAME TIME GFS ALSO CENTERS UPPER HIGH OVER SOUTHERN NEVADA BY THEN. THIS WOULD RAISE TEMPERATURES AND BRING ABOUT SOME SUBSIDENCE OVER MOST OF FORECAST AREA. RIGHT NOW WILL GO WITH A MOSTLY DRY FORECAST WITH SILENT POPS OVER TERRAIN OF MOHAVE AND LINCOLN COUNTIES. && .AVIATION...THUNDERSTORMS ARE POSSIBLE FOR THE NEXT SEVERAL HOURS OVER THE LAS VEGAS VALLEY. THEY ARE ALSO POSSIBLE AGAIN TOMORROW AFTERNOON...HOWEVER PROBABILITIES FOR THIS WILL BE LESS THAN IN THE LAST TWO DAYS. && .VEF WATCHES/WARNINGS/ADVISORIES... .NV...NONE. .AZ...NONE. .CA...NONE. && PIERCE/JACQUES
