AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE RENO NV 318 PM PDT MON JUL 14 2008 .SHORT TERM... SCATTERED...VERY SLOW MOVING SHOWERS AND THUNDERSTORMS HAVE DEVELOPED NEAR THE SIERRA CREST SOUTH OF LAKE TAHOE...WITH ISOLATED CONVECTION ELSEWHERE. THE CONCERN WITH STORMS SOUTH OF TAHOE IS HEAVY RAIN WITH SLOW MOVEMENT AND RADAR STORM PRECIP ESTIMATES OF 1 TO 1.5 INCH INDICATED THROUGH 3 PM. THE CONCERN FOR STORMS ELSEWHERE...ESPECIALLY OVER NORTHWEST LASSEN COUNTY (NORTH OF EAGLE LAKE)...IS OUTFLOW WINDS COMBINED WITH ISOLATED LIGHTNING STRIKES. THE RAWS AT ASH VALLEY OVER FAR NORTHERN LASSEN COUNTY HAD A TEMPERATURE/DEWPOINT SPREAD OF 62 DEGREES AT 2 PM...MORE THAN SUFFICIENT TO DROP SOME VERY GUSTY WINDS WITH THUNDERSTORMS. CONVECTIVE ACTIVITY WILL BE WANING AFTER THIS EVENING AS SOUTHWEST FLOW ALOFT INCREASES WITH ENERGY MOVING INTO THE NORTHWEST STATES. THE INCREASED SOUTHWEST FLOW ALOFT IN SUMMERTIME MEANS DRIER AND MORE STABLE ATMOSPHERIC CONDITIONS...WHICH WILL CONTINUE THROUGH AT LEAST THURSDAY. THE SLIGHT CHANCE OF THUNDERSTORMS WILL BE CONFINED TO SOUTH OF A BRIDGEPORT TO WALKER LAKE LINE TUESDAY AFTERNOON AND EVENING. HOWEVER...WHILE THUNDERSTORMS ACTIVITY WILL BE WANING...STRONGER WESTERLY FLOW IN THE AFTERNOON AND EVENING WILL LIKELY THROW MORE HAZE AND SMOKE OUR WAY THROUGH LATE WEEK. SORRY FOLKS...BUT UNTIL THE NORTHERN CALIFORNIA FIRES ARE WELL IN HAND THERE WILL BE AN AMPLE SUPPLY OF SMOKE TO SEND OUR WAY. .LONG TERM...FRIDAY THROUGH MONDAY... LITTLE CHANGE WAS MADE TO EXTENDED FORECAST WHICH WILL KEEP TEMPS ABOVE NORMAL THRU EARLY NEXT WEEK WITH SOME VALLEYS IN W-CNTRL NV TOPPING 100 DEGREES. RIDGE OVER THE FOUR CORNERS REGION AND ERN GREAT BASIN IS EXPECTED TO REMAIN NEARLY STATIONARY THRU THE WEEKEND AND MAY DRIFT A BIT EAST AS NEXT TROF OR UPPER LOW APPROACHES THE WEST COAST. OVERALL MODEL GUIDANCE HAS NOT BEEN VERY CONSISTENT ON STRENGTH OF RIDGE AND WHERE NEXT UPSTREAM TROF WILL TRACK...BUT WITHOUT ANY MAJOR JET ENERGY THE RIDGE IS MORE LIKELY TO WIN OUT AND DELAY THE ARRIVAL OF THE NEXT TROF OR CLOSED LOW. THEREFORE NO TSTMS WERE ADDED AT THIS TIME BUT MONDAY MAY BEAR WATCHING FOR POSSIBLE CONVECTION...ESPECIALLY IF THE ECMWF SOLUTION OF A CLOSER APPROACH OF THE LOW INTO NRN CA VERIFIES. MJD && .AVIATION... SMOKE AND HAZE CONDITIONS HAVE IMPROVED SOMEWHAT TODAY WITH VSBY CURRENTLY AT OR ABOVE 6 SM. HOWEVER...INCREASED WEST WINDS LATER TODAY AND UNSTABLE CONDS WILL RAISE THE POSSIBILITY OF NEW SMOKE PLUMES CARRIED IN FROM THE ACTIVE FIRES NEAR BLUE CANYON AND BUTTE/PLUMAS/TEHAMA COUNTIES IN NERN CA. RIDGE LEVEL AND 700 MB WINDS EXPECTED TO BECOME WEST BY THIS EVENING...WHICH WILL LIKELY PRODUCE VSBY THIS EVENING AND LATER TONIGHT SOMEWHAT LOWER THAN YESTERDAY. WILL MENTION PREDOMINANT VSBY 5-6SM AFTER 02Z FOR THE KRNO-KTVL-KTRK SITES. ONE OF MORE OF THESE SITES MAY SEE VSBY DROP TO 3 OR 4 MILES AT TIMES LATE TONIGHT THRU TUES MORNING. ONE UNCERTAINTY IS WHETHER OUTFLOW WINDS AND RAIN FROM SHOWERS AND TSTMS WILL PROVIDE A PERIOD OF REDUCED SMOKE COVERAGE THROUGH PART OF THE EVENING. ISOLD-SCT SHWRS/TSTMS EAST OF THE SIERRA WILL SPAWN A FEW SHORT LIVED OUTFLOW-INDUCED CELLS IN PARTS OF WRN NV AND NERN CA THRU 03Z THIS EVENING MAINLY SOUTH AND WEST OF A CEDARVILLE TO PYRAMID LAKE TO FALLON LINE. LOCALLY HEAVY RAIN...SMALL HAIL AND OUTFLOW OR DOWNDRAFT GUSTS OF 40-50 MPH WILL BE MAIN THREATS FROM THE STRONGER CELLS. MJD && .REV WATCHES/WARNINGS/ADVISORIES... NV...NONE.
