AREA FORECAST DISCUSSION...CORRECTED NATIONAL WEATHER SERVICE RENO NV 328 PM PDT SUN SEP 1 2013 .SYNOPSIS... SMOKE FROM WILDFIRES WILL CONTINUE TO AFFECT PARTS OF THE SIERRA AND WESTERN NEVADA THIS WEEK. SUBTROPICAL MOISTURE WILL BRING INCREASING CLOUDS WITH ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS EARLY IN THE WEEK. HIGH TEMPERATURES NEAR NORMAL THROUGH THE HOLIDAY WEEKEND WILL RISE TO A FEW DEGREES ABOVE AVERAGE FOR MID TO LATE WEEK. && .SHORT TERM... MAIN CHANGES TO THE SHORT TERM FORECAST WERE ADDING NOCTURNAL SHOWERS TONIGHT AND MONDAY MORNING FOR ALL OF EASTERN CALIFORNIA AND WESTERN NEVADA AND FOR NORTHERN WASHOE, PERSHING, AND CHURCHILL COUNTIES LATE TOMORROW NIGHT. SMOKE FROM THE RIM FIRE IS ONCE AGAIN MAKING ITS PRESENCE KNOWN AS SOUTH-SOUTHWEST FLOW ALOFT PUSHES IT INTO THE LAKE TAHOE BASIN AND FAR WESTERN NEVADA. UNFORTUNATELY, THE FLOW ALOFT WILL REMAIN SIMILAR TO TODAY THROUGH AT LEAST TUESDAY SO SMOKE WILL CONTINUE TO SPREAD OVER THE SIERRA (MAINLY NORTH OF MONO LAKE) AND WESTERN NEVADA, ESPECIALLY IN THE AFTERNOON AND EVENING. LOOKING AT THE WATER VAPOR SATELLITE, SURFACE OBSERVATIONS, AND PRECIPITABLE WATER PLOTS FROM NEAR MAMMOTH LAKES AND RENO, MOISTURE CONTINUES TO WORK ITS WAY INTO THE NORTHERN SIERRA AND WESTERN NEVADA AROUND A RIDGE CENTERED OVER THE FOUR CORNERS AND ROCKIES. THE PRECIPITABLE WATER IS RAPIDLY RISING AND HAS REACHED TO NEAR 0.90" THIS AFTERNOON. PRECIPITABLE WATERS WILL REMAIN ELEVATED AT BETWEEN 0.75" AND 1.1" THROUGH AT LEAST TUESDAY. WITH PLENTY OF MOISTURE BECOMING ESTABLISHED TODAY, THE NATURE AND INTENSITY OF CONVECTION WILL BE DETERMINED BY ANY SUBTLE UPPER WAVES AND INSTABILITY. FOR TONIGHT, AFTER DIURNAL CONVECTION DIES OUT THIS EVENING THERE COULD STILL BE A SHOWER JUST ABOUT ANYWHERE WITH THE MOISTURE IN PLACE AND A POSSIBLE UPPER DISTURBANCE (IN SOME MODELS AND NOT OTHERS) APPROACHING FROM SOUTHERN CALIFORNIA. MONDAY, SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS ARE EXPECTED OVER WESTERN NEVADA AND THE SIERRA SOUTH OF HIGHWAY 50 AS MOISTURE COMBINES WITH DAYTIME HEATING. THUNDERSTORMS ARE EXPECTED TO BE LIMITED SOMEWHAT BY COPIOUS CLOUD COVER (CUTTING DOWN INSTABILITY). WHILE STORMS WILL HAVE DECENT MOVEMENT WITH MODERATE WINDS ALOFT THE HIGH PWATS WILL ALLOW LOCALLY HEAVY RAIN WITH THE STRONGER STORMS. ON TUESDAY, SCATTERED THUNDERSTORMS ARE EXPECTED TO BEGIN SHIFTING FARTHER SOUTH AND EAST AS MORE SOUTHWESTERLY FLOW ALOFT KICKS IN AS AN UPPER LOW APPROACHES THE OREGON COAST. STILL, THE LOWER LEVEL FLOW LOOKS TO REMAIN SOUTHERLY ENOUGH TO BRING ANOTHER BOUT OF SMOKE NORTH INTO THE RENO-TAHOE AREA IN THE AFTERNOON. SNYDER .LONG TERM...WEDNESDAY THROUGH SUNDAY... THE LAST FEW MODEL RUNS ARE IN CONSIDERABLY BETTER AGREEMENT THEN PREVIOUS DAYS ON THE EVOLUTION OF THE LOW PRESSURE OFF THE OREGON COAST. MODELS HAVE TRENDED TOWARDS THE LOW PRESSURE BEING CUT OFF FROM THE MAIN FLOW AND STALLING AS IT APPROACHES THE OREGON COAST ON TUESDAY. SLOW NORTHEAST PROGRESS BEGINS AGAIN ON WEDNESDAY AS THE LOW SLOWLY MOVES OVER THE OLYMPIC PENINSULA BY FRIDAY. AFTER FRIDAY MODELS LOSE CONSENSUS ON THE EXACT TRACK OF THE LOW BUT AGREE ON THE OVERALL TREND OF HIGH PRESSURE BUILDING BACK INTO CA/NV FROM THE SOUTHWEST WITH OVERALL DRYING CONDITIONS. ONLY MINOR CHANGES TO FORECAST. COOLED TEMPS A LITTLE AND CONTINUED TO DRY OUT FRIDAY AND BEYOND AS CONFIDENCE HAS INCREASED ON WHEN DRY AIR WILL WORK ITS WAY BACK INTO THE AREA. EXTENDED HAZE AND AREAS OF SMOKE THROUGH THURSDAY AS CONSISTENT SOUTHWEST FLOW ALOFT WILL KEEP THE SIERRA AND WESTERN NEVADA DOWNWIND OF THE RIM FIRE. CONDITIONS WILL CONTINUE TO BE SIMILAR TO THE PREVIOUS WEEK WHERE SMOKE CONDITIONS WILL FLUCTUATE FROM DAY TO DAY DEPENDING ON SMOKE OUTPUT FROM THE FIRE AND SMALLER SCALE MOUNTAIN FLOWS. TOLBY && .AVIATION... MAIN CONCERN CONTINUES TO BE SMOKE FROM THE RIM FIRE. EXPECT BIGGER IMPACTS TO KCXP, KTVL (BASED ON HIGHER MINS), AND KRNO WITH LESS AT KMMH/KTRK. BEST VIS TO OCCUR DURING MORNINGS/EARLY AFTERNOONS BEFORE MORE SMOKE MOVES IN DURING THE LATE AFTERNOON. WITH WINDS STRONGER MONDAY AND MIDWEEK, THE SMOKE PLUME WILL TRAVEL FURTHER NORTH ASSUMING THE FIRE IS STILL VERY ACTIVE (WHICH IT LIKELY WILL BE).
