The local office's own words before this special weather statement went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Reno, NV wrote its last area forecast discussion before this special weather statement went out at Aug 8, 12:44 PM PDT, 4 hours 22 minutes earlier.
Area forecast discussion, Aug 8, 12:44 PM PDT, 4 hours 22 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE RENO NV 1244 PM PDT FRI AUG 8 2014 .SYNOPSIS... ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS ARE EXPECTED THROUGH THE WEEKEND, MAINLY IN THE AFTERNOON AND EVENING, BUT A FEW STORMS ARE POSSIBLE SUNDAY NIGHT. THUNDERSTORM COVERAGE MAY DECREASE BY EARLY TO MID NEXT WEEK. HIGH TEMPERATURES WILL REMAIN NEAR AVERAGE. && .SHORT TERM... THE SHORT TERM FORECAST HAS REMAINED RELATIVELY UNCHANGED TODAY. MID TO UPPER LEVEL FLOW IS MAINLY ZONAL AND FAIRLY LIGHT ALTHOUGH A SLIGHT INCREASE IN WESTERLY FLOW IS EXPECTED LATE THIS AFTERNOON. LIGHT FLOW...ABUNDANT RESIDUAL MOISTURE AND DAYTIME HEATING IS ALREADY STARTING TO PRODUCE SHOWERS AND THUNDERSTORMS IN FAVORED DEVELOPMENT AREAS FROM MONO COUNTY TO THE EAST NORTHEAST AND ACROSS PARTS OF THE BASIN AND RANGE. CONVECTION SHOULD BECOME MORE WIDESPREAD THROUGH THE AFTERNOON. WITH SOME INCREASE IN WESTERLY FLOW WE ARE EXPECTING ACTIVITY TO PUSH OUT OF THE TAHOE BASIN BY LATE AFTERNOON. FLOW BECOMES MORE SOUTH-SOUTHWEST SATURDAY AS MODELS TRY TO DIG A CLOSED LOW DOWN THE CA COAST. THIS WOULD ALLOW A BIT MORE MOISTURE TO BE DRAWN INTO THE SOUTHERN CWA...BUT MAY INHIBIT THE NORTHERN CWA FROM DEVELOPING QUITE AS MUCH. THE PRESENCE OF INCREASE SOUTH- SOUTHWEST FLOW MY ALSO ACT TO TEMPORARILY PUSH ACTIVITY OUT OF TAHOE SATURDAY AFTERNOON AND EVENING...BUT FOR NOW WE DO NOT HAVE THE CONFIDENCE TO MAKE THAT CHANGE. THE BETTER CHANCE FOR SCATTERED COVERAGE WOULD APPEAR TO BE FROM MONO COUNTY NORTH INTO THE PINE NUTS AND JUST EAST OF THE CARSON RANGE IN WESTERN NEVADA. THE UPPER LOW DEEPENS A LITTLE BY SUNDAY AND DIGS FARTHER SOUTH. THIS SHOULD PUT THE NORTHERN CWA IN THE MORE FAVORABLE NE QUADRANT AND INCREASE THE UPPER DIVERGENCE OVER NE CA AND FAR NW NV. LOW TO MID BACKING OF THE FLOW SHOULD ALSO ALLOW MORE MOISTURE TO BE DRAWN NORTH. UNLIKE TONIGHT AND SATURDAY WHEN STORM MOTIONS WILL BE FAIRLY LIGHT AND HEAVY RAIN THE BIGGEST THREAT...THE STORM MOTIONS SUNDAY ARE LIKELY TO INCREASE OVER THE NORTHERN HALF OF THE CWA AS MID LEVEL SHEAR INCREASES. THE SOUTHERN HALF WILL CONTINUE TO SEE SLOW STORM MOTIONS AND HEAVY RAIN. FOR THE NORTH STORMS COULD BE A MIXED BAG OF HAIL...GUSTY WINDS AND TRAINING CELLS THAT PRODUCE HEAVY RAINS. THERE IS ALSO THE POTENTIAL FOR DRY LIGHTNING STRIKES OUTSIDE OF THE CELLS SUNDAY...BUT FUELS REMAIN SOMEWHAT MOIST OVER MUCH OF NE CA...SO FOR NOW THE FIRE WEATHER THREAT MAY BE MUTED. 20 .LONG TERM...TUESDAY THROUGH FRIDAY... AN UPPER LOW NEAR THE CA COAST SHOULD PROVIDE ONE MORE DAY OF FAVORABLE CONDITIONS FOR SHOWERS AND THUNDERSTORMS MONDAY. BY TUESDAY THERE IS A LARGE SPREAD AMONG THE VARIOUS MODEL FORECASTS IN TERMS OF THE INLAND TRACK OF THE UPPER LOW AS A STRONGER TROUGH APPROACHES THE PAC NW COAST. MOST FORECASTS INDICATE A DRIER AIR MASS FOR THE SIERRA AND WESTERN NV TUESDAY BUT SOME FORECASTS SHOW FAIRLY STRONG FORCING FOR LIFT. AS SUCH, A SLIGHT CHANCE FOR THUNDERSTORMS WAS INTRODUCED FOR THE EASTERN SIERRA AND WESTERN NV, EXCLUDING MONO AND MINERAL COUNTIES, FOR TUESDAY AFTERNOON AND EVENING. THE SPREAD AMONG MODEL FORECASTS HAS BECOME LARGER THAN IT WAS YESTERDAY, WHICH MAKES WED-FRI A LOW CONFIDENCE FORECAST. FOR NOW, THE FORECAST WILL CONTINUE TO REFLECT THE MORE CONSISTENT GFS WITH DRY CONDITIONS AND LIGHT WINDS WED-FRI. JCM && .AVIATION... STORMS ARE DEVELOPING ACROSS THE SIERRA AGAIN THIS AFTERNOON. A LITTLE MORE WESTERLY FLOW COMPARED TO YESTERDAY WILL HELP PUSH THE CONVECTION EAST OF THE TAHOE BASIN AND MOST LIKELY EAST OF THE RENO-CARSON CITY AREA BY 00Z. MAIN IMPACT FROM STORMS WILL CONTINUE TO BE HEAVY RAINFALL. ABUNDANT MOISTURE WILL LIMIT OUTFLOW TO 20-25KT IN THE SIERRA AND AROUND 35KT FOR LOWER ELEVATIONS. UPPER LOW WILL DEVELOP NEAR THE CENTRAL CA COAST AND KEEP SCATTERED SHOWERS AND THUNDERSTORMS ANCHORED TO THE EASTERN SIERRA THIS WEEKEND. GIVEN THE LOCATION OF THE UPPER LOW, ISOLATED NOCTURNAL STORMS ARE POSSIBLE SAT/SUN NIGHTS. PATCHY FOG IS POSSIBLE IN THE MARTIS VALLEY BURNING OFF AROUND 16Z EACH MORNING WHEN IT DOES FORM.
