AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ELKO NV 438 PM PDT TUE JUL 27 2010 .SYNOPSIS...A MOIST SOUTHERLY FLOW BETWEEN A TROUGH OF LOW PRESSURE TO THE NORTHWEST AND A RIDGE OF HIGH PRESSURE TO THE SOUTHEAST WILL CONTINUE TO RESULT IN SCATTERED SHOWERS AND THUNDERSTORMS THROUGH THURSDAY FOR EASTERN AND CENTRAL PORTIONS OF THE SILVER STATE...WITH DRIER WEATHER LIKELY FURTHER WEST. THUNDERSTORMS WILL BE LESS LIKELY OVER THE WEEKEND AS WINDS ALOFT TURN MORE WESTERLY. && .SHORT TERM...TONIGHT THROUGH THURSDAY. PLENTY OF SHOWER AND THUNDERSTORM ACTIVITY IS ONGOING ACROSS THE REGION AT PRESENT...COURTESY OF THE TROUGH TO THE WEST AND THE CONTINUED SURGE OF MONSOONAL MOISTURE FROM THE SOUTH. LATEST NAM AND GFS KEEP CAPE AND NEGATIVE LI'S AROUND THROUGH THE NIGHT...THOUGH BECOMING LESS INTENSE AND MORE ISOLATED AS THE NIGHT GOES ON...SO SOME ISOLATED THUNDERSTORMS MAY LINGER THROUGH THE NIGHT AND INTO TOMORROW MORNING BEFORE WIDESPREAD DEVELOPMENT OCCURS AGAIN BY TOMORROW AFTERNOON. DEVELOPMENT TOMORROW WILL BE AIDED BY A SHORTWAVE TROUGH PASSING WELL TO OUR NORTHWEST. THIS SHORTWAVE MAY ALSO HELP SPARK OFF A FEW SEVERE THUNDERSTORMS...SO ANYONE SPENDING TIME OUTDOORS WILL NEED TO KEEP AN EYE TO THE SKY. HOWEVER...THIS SHORTWAVE WILL ALSO HELP TO CAUSE ACTIVITY TO CEASE ONCE THE TROUGH AXIS PASSES TOMORROW EVENING. THE FLOW WILL ALSO TURN A BIT MORE WESTERLY ALOFT AFTER THE SHORTWAVE PASSES...SO IT LOOKS LIKE THUNDERSTORMS THURSDAY AFTERNOON WILL BE A BIT MORE CONFINED TO THE EASTERN THIRD OF THE CWA. REGARDLESS...THERE WILL STILL BE SOME CONVECTION AROUND. WITH GREATER CLOUD COVER EXPECTED...HIGHS TOMORROW WILL BE A TAD COOLER THAN TODAY...MOSTLY STAYING IN THE 80S IN MANY VALLEYS...THOUGH GREATER SUNSHINE BEHIND THE TROUGH SHOULD ALLOW FOR A SLIGHT WARMING AGAIN ON THURSDAY.

THRU THE EXTENDED...MID-LEVEL MOISTURE IS HIGHEST ACROSS THE EASTERN HALF OF NEVADA...AND LOWER WEST. THE GFS HAS MID-LEVEL MOISTURE RELATIVELY LOW FRIDAY AND SATURDAY... WITH AN INCREASING TREND SUNDAY...MONDAY...AND TUESDAY. THE ECMWF IS SIMILAR BUT WITH A BIT MORE MOISTURE FRIDAY AND SATURDAY...AND A BIT LESS THAN THE GFS SUNDAY...MONDAY...AND TUESDAY. LOOKING AT PW'S...THEY ARE RELATIVELY HIGH FRIDAY...AND THEN LOW THRU THE REMAINDER OF THE EXTENDED...NEAR OR BELOW 0.50 INCHES...AS A SHORT WAVE PASSING TO THE NORTH ON SATURDAY DRIES THE AREA OUT. THE EXCEPTION IS WHITE PINE COUNTY...WHERE PW'S PERIODICALLY REACH 0.75 INCHES. WILL STAY CLOSE TO CURRENT FCST WITH ONLY MINOR CHANGES TO POPS AND WX GRIDS. REA && .AVIATION...ISOLATED SHOWERS AND TSTMS WILL CONTINUE THRU THIS EVENING AND THE OVERNIGHT HOURS...WITH SCT TO BKN CLOUD BASES BETWEEN 6000 AND 12000 FT...AND ISOLATED MVFR VSBYS IN TSTMS.
