WESTERN NEVADA AND EASTERN CALIFORNIA FORECAST DISCUSSION NATIONAL WEATHER SERVICE RENO NV 215 PM PDT TUE JUL 22 2003 MAIN AREAS OF CONVECTION THIS AFTERNOON INCLUDE MONO AND MINERAL COUNTIES TO THE SOUTH AND NORTHERN PORTIONS OF LASSEN AND WASHOE COUNTIES TO THE NORTH. CUMULUS BUILDUPS WERE OCCURRING IN THE RENO AREA BUT NOT TO THE POINT OF PRODUCING THUNDERSTORMS AS OF 215 PM. WITH THE HOT TEMPERATURES AND HIGH DEW POINTS THE COVERAGE OF THUNDERSTORMS SHOULD INCREASE AS THE AFTERNOON GOES ON. THE MORNING MODELS CONTINUED THE SOUTHEAST FLOW ALOFT OVER THIS AREA AND PRODUCED SOME QPF OVERNIGHT. WILL ACCEPT THAT SOLUTION AND KEEP NOCTURNAL SHOWERS OR THUNDERSTORMS IN THE FORECAST TONIGHT AND WEDNESDAY NIGHT. A WEAK VORTICITY LOBE MOVES THROUGH NORTHWEST NV WEDNESDAY AFTERNOON AND IF TIMING IS RIGHT WILL PRODUCE HEAVY RAIN WITH THUNDERSTORMS. THE HIGH WEAKENS ON THURSDAY AND FLOW BECOMES SOUTHWEST AND INCREASES DURING THE DAY. THIS SHOULD HELP TO PUSH CONVECTION INTO THE NORTHERN AND EASTERN PORTIONS OF THE CWA. THE SOUTHWEST FLOW INCREASES OVERNIGHT AND BY FRIDAY CONVECTION IS LIMITED TO THE EASTERN PORTIONS OF CHURCHILL...PERSHING AND MINERAL COUNTIES. RC IN THE EXTENDED...SATURDAY THROUGH TUESDAY...SATURDAY WAS KEPT DRY ALTHOUGH GFS INDICATED SOME INSTABILITY IN WEST CENTRAL NV. MOST MOISTURE WAS JUST EAST OF CHURCHILL AND MINERAL COUNTIES WHILE THERMAL TROUGH FOR FOCUSING SURFACE CONVERGENCE WAS WELL INTO EASTERN NV BY 00Z...MAKING LESS FAVORABLE CONDITIONS FOR ORGANIZED TSTM DEVELOPMENT IN WEST CENTRAL NV. FROM SUNDAY THROUGH TUESDAY...MODELS DIFFERED IN LOCATION AND MOVEMENT OF THE REBUILDING RIDGE CENTER. GFS REBUILT THE RIDGE OVER NV BY MONDAY WHILE CANADIAN MOVED THE CENTER FROM THE FOUR CORNERS TO SOUTHERN CA AND THE ECMWF HAD AN UNDETERMINED RIDGE LOCATION BY MONDAY AS IT DID NOT PLOT A 594 DM HEIGHT CONTOUR. WITH THIS UNCERTAINTY...THERE IS NO CONVINCING REASON TO CHANGE MUCH FROM THE CURRENT FORECAST WHICH KEEPS SLIGHT CHANCES IN THE SOUTHERN AND EASTERN ZONES EACH AFTERNOON FROM SUNDAY THROUGH TUESDAY. TEMPS WILL AGAIN APPROACH 100 DEGREES BY EARLY NEXT WEEK ESPECIALLY IF THE GFS SCENARIO OCCURS. MJD .REV...NONE.
