TUESDAY THROUGH THURSDAY NIGHT: Partly cloudy with a chance of showers and thunderstorms. Highs 71 to 81. Lows 40 to 50.
FRIDAY: Partly cloudy. Highs 69 to 79.

UPDATE (8:41 AM PDT)...SHOWERS ARE DEVELOPING OVER NORTHERN LYON CHURCHILL AND MINERAL COUNTIES AS A WAVE MOVES INTO THE AREA. ABUNDANT MOISTURE WITH THE WAVE HAS ALSO ALLOWED A LARGE CLOUD SHIELD TO DEVELOP OVER THE REGION. THIS WILL LIMIT SURFACE BASED INSTABILITY AND MAY HELP  TO INHIBIT STRONG CONVECTION THIS AFTERNOON. A FLASH FLOOD WATCH IS IN PLACE FOR TODAY ALONG AND SOUTH OF I-80 WITH HIGH SURFACE DEW POINTS, ABUNDANT MOISTURE AND LOW STORM MOTIONS. HOWEVER NOT ALL LOCATIONS WILL BE IMPACTED BY A THUNDERSTORM AND/OR HEAVY RAINFALL. WITH THE MANY LARGE OUTDOOR ACTIVITIES TAKING PLACE TODAY AROUND THE REGION, THUNDERSTORMS ARE A CONCERN EVEN IF THEY DO NOT LEAD TO FLASH FLOODING.  GUSTY WINDS AND DANGEROUS LIGHTNING ARE ALSO POSSIBLE. HAVE A PLAN TO RETURN TO SHELTER IF A THUNDERSTORM APPROACHES YOUR LOCATION, ESPECIALLY IF YOU ARE NEAR A LAKE. HEAVY RAINFALL CAN ALSO LEAD TO HYPOTHERMIA, CARRY RAIN GEAR IF YOU ARE GOING ON A HIKE TODAY.

SYNOPSIS (3:13 AM PDT)...VERY MOIST AND UNSTABLE CONDITIONS WILL ALLOW SHOWERS AND THUNDERSTORMS TO DEVELOP TODAY. A FEW STRONG THUNDERSTORMS THIS AFTERNOON MAY PRODUCE TORRENTIAL RAINFALL AND FLASH FLOODING. LOW PRESSURE NEAR THE CALIFORNIA COAST WILL KEEP THE THREAT FOR SHOWERS AND THUNDERSTORMS THE NEXT SEVERAL DAYS.

SIERRA LAKE TAHOE FORECAST DISCUSSION: FOR TODAY, WE HAVE ISSUED A FLASH FLOOD WATCH FOR MUCH OF THE REGION GENERALLY FROM I-80 SOUTHWARD. THERE ARE SEVERAL FACTORS FAVORING THE POTENTIAL FOR HEAVY RAINFALL CAPABLE OF PRODUCING FLASH FLOODING. THE AIR MASS REMAINS UNUSUALLY MOIST WITH DEW POINTS MAINLY IN THE 50S AND PRECIPITABLE WATER VALUES BETWEEN 1 AND 1.25 INCH THIS AFTERNOON AND EVENING, WITH PLENTY OF INSTABILITY AS LIFTED INDEX RANGES FROM -2 TO -4 C IN MOST AREAS. MODEL GUIDANCE HAS BEEN RELATIVELY CONSISTENT WITH PUSHING AN UPPER LEVEL DISTURBANCE NORTHWARD INTO THE SIERRA AND WESTERN NV THIS AFTERNOON, WHICH WOULD PROVIDE ADDITIONAL FORCING FOR GENERATING THUNDERSTORMS. MODEL SOUNDINGS ALSO INDICATE LIGHT MID LEVEL FLOW WHICH WOULD RESULT IN GENERALLY SLOW CELL MOVEMENT, WITH POSSIBLE CELL TRAINING OR REDEVELOPMENT OVER THE SAME AREAS. RECENT RAINFALL HAS PRODUCED SATURATED GROUND IN SOME LOCATIONS, AND WE HAVE ALREADY RECEIVED SOME FLOODING IN THE PAST FEW DAYS, INCLUDING THE HIGHLY SENSITIVE WASHINGTON FIRE SCAR IN ALPINE COUNTY. THE MAIN LIMITING FACTOR IS IF CLOUD COVER BECOMES TOO THICK TO ALLOW THE FULL INSTABILITY TO BE REALIZED AND REDUCING THUNDERSTORM INTENSITY. HOWEVER, WITH SO MANY FAVORABLE FACTORS IN PLAY DURING THE MIDDLE OF THIS VERY BUSY HOLIDAY WEEKEND, THE DECISION WAS MADE TO ISSUE THE WATCH FOR TODAY'S THUNDERSTORM EVENT WHICH BEEN WIDELY ADVERTISED THE PAST SEVERAL DAYS. FARTHER NORTH INTO NORTHEAST CA-NORTHWEST NV, LOCALLY HEAVY RAIN IS POSSIBLE, BUT COVERAGE IS NOT EXPECTED TO BE WIDESPREAD WITH CELL MOVEMENT A LITTLE FASTER SO THEY WERE NOT INCLUDED IN THE FLASH FLOOD WATCH. IN ADDITION TO THE FLASH FLOOD POTENTIAL, SOME HAIL OR STRONG OUTFLOW GUSTS WILL BE POSSIBLE WITH STRONGER STORMS, WITH FREQUENT LIGHTNING STRIKES ALSO IMPACTING OUTDOOR ACTIVITIES THIS AFTERNOON AND EARLY EVENING. AS THE DISTURBANCE MOVES FARTHER NORTH THIS EVENING, MOST OF THE CONVECTION WILL ALSO DECREASE. THERE MAY BE A  FEW LEFTOVER SHOWERS OR THUNDERSTORMS AFTER 9 PM, BUT FOR MOST AREAS THE WORST WEATHER CONDITIONS SHOULD HAVE PASSED THROUGH. FOR SUNDAY, LINGERING MOISTURE AND INSTABILITY WILL CONTINUE BUT FORCING IS LIKELY TO BE WEAKER, RESULTING IN LESS THUNDERSTORM COVERAGE COMPARED TO TODAY. THE AREAS MORE LIKELY TO RECEIVE CONVECTION INCLUDE AREAS SOUTH OF HIGHWAY 50 AND NORTH OF SUSANVILLE-GERLACH. BY MONDAY, UPPER LOW OVER THE EASTERN PACIFIC MOVES SLOWLY TOWARD THE CALIFORNIA COAST, WITH SOUTH TO SOUTHEAST FLOW ALOFT DRAWING IN MORE MOISTURE AND INSTABILITY DURING THE AFTERNOON. THERE APPEARS TO BE ANOTHER DISTURBANCE ROTATING INTO THE SIERRA, WHICH WOULD LEAD TO INCREASED THUNDERSTORM CHANCES AGAIN. INITIAL CELLS ARE MOST LIKELY TO FORM NEAR THE SIERRA, WITH ACTIVITY THEN SPREADING SLOWLY EAST. IF TODAY REACHES ITS POTENTIAL FOR PRODUCING HEAVY RAIN AND FLOODING, WE MAY BE DEALING WITH ADDITIONAL FLOOD POTENTIAL FOR MONDAY.

LONG TERM WEATHER....TUESDAY THROUGH FRIDAY....MEDIUM RANGE OPERATIONAL MODELS HAVE COME MORE IN LINE WITH THE EVOLUTION OF A CLOSED UPPER LOW THAT MOVES INTO CALIFORNIA DURING THE EXTENDED PERIOD BEFORE STARTING TO OPEN INTO A WAVE AND LIFT OUT OF THE AREA BY LATE FRIDAY. THE GEFS ENSEMBLE MEMBERS ALL GENERALLY SUPPORT THE TIMING OF THIS FEATURE WITH ONLY A FEW EXCEPTIONS THAT LIFT THE LOW OUT A LITTLE QUICKER EARLY FRIDAY. WHAT DOES ALL THIS MEAN FOR THE FORECAST? THE CONTINUED PRESENCE OF THE LOW TO THE WEST THROUGH MOST OF THE FORECAST PERIOD ALONG WITH A HIGH WELL EAST OF THE AREA WILL DRAW MOISTURE NORTH INTO THE REGION AND PRODUCE ENOUGH INSTABILITY TO DEVELOP THUNDERSTORMS EACH DAY. UPPER  DIFFLUENCE TO THE NORTH AND NORTHEAST OF THE LOW SHOULD CAUSE NORTHEAST CALIFORNIA AND NORTHWEST NEVADA TO HAVE THE BEST CHANCE OF CONVECTION AND POSSIBLY INTO THE OVERNIGHT HOURS. SO POPS WERE INCREASED A LITTLE EACH DAY NORTH OF INTERSTATE 80 AND POPS WERE INCLUDED FOR THE  OVERNIGHT HOURS THROUGH WEDNESDAY NIGHT. AFTER THAT THERE IS A BIT TOO MUCH UNCERTAINTY IN INSTABILITY DURING THE OVERNIGHT HOURS. WITH THE UPPER LOW GETTING CLOSER AND AN INCREASE IN CLOUD COVER...DAYTIME HIGHS SHOULD BE AT OR POSSIBLY BELOW AVERAGE DURING THE EXTENDED PERIOD. OVERNIGHT LOWS SHOULD REMAIN ABOVE AVERAGE DUE TO INCREASED CLOUD COVER.
