AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE RENO NV 915 PM PDT FRI JUL 21 2006 .UPDATE... WOW...LINE OF STORMS CONTINUING TO MOVE NORTHWEST. EXPECT TO GRADUALLY WEAKEN AS INSTABILITY WANES BUT SHOULD CONTINUE WITH GOOD CONVERGENCE ALONG LEADING EDGE INTO EARLY MORNING. LOCALLY HEAVY RAINS STILL POSSIBLE. WALLMANN && .PREV DISCUSSION...ISSUED AT 300 PM SHORT TERM... TEMPERATURES TO CONTINUE CONSIDERABLY ABOVE NORMAL THROUGH THE SHORT TERM...WITH CHANCES OF STORMS EACH DAY WITH PLENTY OF MOISTURE AND DAYTIME HEATING AVAILABLE. THE COMBINATION OF AN EXITING JET STREAK OVER NORTHERN CALIFORNIA AND A DISTURBANCE MOVING UP THE WESTERN SLOPES OF THE SIERRA CAUSED SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS INTO THE AFTERNOON HOURS. A PRONOUNCED DRY SLOT IS MOVING NORTH ALONG THE CALIFORNIA AND NEVADA BORDER BEHIND THE EXITING DISTURBANCE. SWITCHING TO THE VISIBLE SATELLITE...ISOLATED THUNDERSTORMS ARE FIRING OVER CENTRAL NEVADA DUE TO HEATING. BUILDING CUMULUS ARE SHOWING SIGNS OF SPREADING INTO MINERAL AND CHURCHILL COUNTIES AT THIS TIME...AND WILL LIKELY CONTINUE TO SPREAD NORTH AND WEST DURING THE REST OF THE AFTERNOON AS HEATING IMPINGES UPON THOSE AREAS. TONIGHT...I CANNED THE AFTER MIDNIGHT POPS. WITH THE JET STREAK AND THE UPPER DISTURBANCE EXITING THIS EVENING AS DRIER AIR ALOFT WORKS IN...I SEE NO REASON THAT WE WILL GET ANY DYNAMICALLY INDUCED SHOWERS OR STORMS ANYWHERE. ALSO...LOOKING AT SATELLITE WINDS AND MODELS...I CANT FIND ANY KIND OF JET STREAK ANYWHERE TO JUSTIFY ELEVATED SHOWERS OR STORMS. SATURDAY...FLOW ALOFT TURNS SOUTHERLY AROUND THE RIDGE NEAR THE UTAH AND NEVADA BORDER. WITH STRONG HEATING AND PLENTY OF MOISTURE STILL REMAINING...A LIGHT WESTERLY WIND IN THE LATE AFTERNOON (EXPECTED) SHOULD BE ALL IT TAKES TO FIRE SCATTERED THUNDERSTORMS ALONG THE SIERRA AND FAR WESTERN NEVADA. SUNDAY...THE FLOW IS PROGGED TO TURN MORE SOUTHWESTERLY ALOFT...WHICH SHOULD PUSH THE BEST CONVERGENCE EVEN FURTHER OFF THE SIERRA INTO THE GREAT BASIN. BY MONDAY...THE TREND OF STRONGER AFTERNOON WESTERLIES WILL CONTINUE...WHICH THEORETICALLY SHOULD SEND THE BEST MOISTURE/STORMS EAST OF THE RENO AND TAHOE ZONES. I HAVE HELD ONTO THE RUNNING SLIGHT CHANCE EVERYWHERE FOR NOW AS I WOULD HATE TO HAVE TO FLIP FLOP POPS BACK INTO THE RENO AND TAHOE ZONES IF THE FLOW MONDAY IS NOT AS STRONG AS CURRENTLY PROGGED. SNYDER .LONG TERM...TUESDAY THROUGH FRIDAY... ON TUESDAY THE STRONG RIDGE REMAINS CENTERED OVER THE SWRN CONUS. EVEN WITH A PROGRESSIVE UPPER FLOW ACROSS THE NRN TIER...THIS RIDGE SHOULD STAY IN PLACE THROUGH THE EXTENDED SINCE THERE WILL BE NO SYSTEMS TO HELP AMPLIFY THE UPPER FLOW AND THUS IMPINGE ON THE RIDGE TO THE SOUTH. AS A RESULT CONDITIONS WILL CONTINUE TO BE RELATIVELY WARM THROUGH FRIDAY ACROSS WRN NEVADA AND THE ERN SIERRA. DID NOT MAKE ANY MAJOR CHANGES TO THE EXTENDED FORECAST. KEPT AFTN HIGHS IN THE TRIPLE DIGITS ACROSS MUCH OF WRN NEVADA. TEMPERATURES WILL ALSO CONTINUE TO BE WARM IN THE SIERRA WITH AFTN HIGHS IN THE UPPER 80S TO NEAR 90 DEGREES. WITH THE STRONG LLVL HEATING EACH DAY INSTABILITIES WILL BE HIGH. A SERIES OF VORT MAXIMA ROUNDING THE WRN EDGE OF THE RIDGE WILL ALSO PROVIDE SOME UPPER LEVEL SUPPORT FOR CONVECTION...SO WILL CONTINUE WITH MENTION OF AFTN AND EVENING TSTMS ACROSS MOST OF THE CWFA. OHARA && .AVIATION... VFR CONDITIONS EXCEPT GUSTY WINDS AND LOCALLY HEAVY RAINFALL NEAR ISOLD TSTMS...MAINLY OVER ERN ROUTES FROM 21Z TO 04Z. OHARA && .REV WATCHES/WARNINGS/ADVISORIES... NV...NONE. CA...NONE. &&
