MOJAVE DESERT/SOUTHERN GREAT BASIN AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LAS VEGAS NV 315 PM PDT FRI SEP 6 2002 .SYNOPSIS...A VERY MOIST SOUTHWEST FLOW OVER THE SOUTHERN GREAT BASIN AND THE MOHAVE DESERT WILL KEEP SCATTERED SHOWERS AND THUNDERSTORMS OVER THE AREA THROUGH THE FIRST PART OF THE WEEKEND. DRYING WILL BE SEEN BY SUNDAY AS THE FLOW CHANGES DUE TO A TROUGH OF LOW PRESSURE MOVING EAST ACROSS THE NORTHERN PORTION OF NEVADA. HOWEVER THIS WILL RESULT IN CONINUED COOL TEMPERATURES AND BREEZY CONDITIONS. .DISCUSSION...CONSIDERABLE MOISTURE CONTINUES TO STREAM NORTHEAST FROM OFF THE CALIFORNIA COAST AND OVER THE CWA THIS AFTERNOON. CONVECTION SO FAR HAS BEEN LIMITED WITH THE BEST AREA BEING THE SOUTHERN PORTION OF MOHAVE COUNTY. OVERNIGHT THE ETA/12Z AVN HAD A BROAD AREA OF NEGATIVE LI OVER MUCH OF THE EASTERN 2/3 OF THE CWA WITH GOOD OMEGA STRETCHING FROM NW NYE COUNTY TO MUCH OF MOHAVE COUNTY WITH A BULLSEYE OF -5 CENTERED OVER SRN NV BY 12Z SAT. ALTHOUGH BEST 700/500 MB COUPLET TO THE NORTH...BELIEVE ENOUGH DYNAMICS...THAT THE OVERNIGHT PERIOD TO BE MUCH MORE ACTIVE THAN TODAY WAS. WEAK COUPLET THEN FORMS OVER THE EASTERN PORTION OF THE CWA SATURDAY WITH GOOD OMEGA AND NEGATIVE LI FOR CONTINUATION OF SHWR/TSTORMS. HOWEVER OFFSHORE TROF TO BEGIN TO BRING MUCH DRIER AIRMASS INTO THE WESTERN ZONES AND STABILIZATION BEGINS TO TAKE PLACE AND WILL REMOVE MENTION OF ACTIVITY THIS AREA. ETA/12Z AVN ARE IN FAIR AGREEMENT WITH KEEPING MOISTURE OVER THE EXTREME EASTERN PORTION OF THE CWA INTO SUNDAY AND DRIER CONDITIONS OVER THE WEST AND WILL GO THIS WAY. BEYOND THE WEEKEND HOWEVER...MODELS BEGIN TO DIVERGE AND QUESTIONABLE WHAT SOLUTION TO FAVOR. EXTENDED...GOING INTO MONDAY...AVN IS FORMING A WEAK LOW OVER/JUST OFF THE SOUTHERN CA COAST...THUS KEEPING SOUTH TO SOUTHWEST FLOW ALOFT OVER THE CWA. AT THE SAME TIME CONSIDERABLE LOW LEVEL MOISTURE REMAINS CAUGHT IN THE FLOW AND SPREADS BACK OVER THE ENTIRE CWA INTO TUESDAY. STABILITY ALSO DECREASES WITH NEGATIVE LIS OVER THE AREA BY TUE AFTN. AT THIS TIME THE AVN IS GENERALLY DOING ITS OWN THING WITH THE LOW FORMATION SO A LITTLE SUSPECT. HOWEVER ANOTHER POINT WHICH MAY COME INTO THE EQUATION IS TROPICAL DEPRESSION ELEVEN E WHICH IS PROGGED TO MOVE NORTH ALONG THE WEST SIDE OF THE BAJA PENISULA THROUGH ATTM 12Z MON. AVN NOT DEPICTING THIS MOISTURE INTRUSION AT THE PRESENT...BUT IF THE TD DOES MOVE NORTH THIS IS SOMETHING THAT WILL POTENTIALL CAUSE SOME PROBLEMS OVER THE DESERT SOUTHWEST. WITH THE UNCERTAINTY WILL GO WITH A BROADBRUSH AND MIDDLE OF THE ROAD FORECAST FOR NOW FOR THE MONDAY THROUGH FRIDAY PERIOD...INTRODUCE CLOUDS AND KEEP TEMPERATURES MODERATE AND WILL GO DRY FOR NOW. JENSEN .LAS..NONE.
