ANOTHER PACIFIC LOW PRESSURE SYSTEM WILL APPROACH NEVADA ABOUT MIDWEEK FOR AN INCREASING THREAT OF SHOWERS AND COOLER WEATHER BY THURSDAY. && .SHORT TERM...THE DEEP MOISTURE PLUME FROM THE PACIFIC WILL CONTINUE TO SWEEP INTO NORTHERN NEVADA TONIGHT. ISOLATED THUNDERSTORMS ARE POSSIBLE WITH THE SHOWERS NEAR THE IDAHO BORDER THIS EVENING AS A WEAK S/WV BRUSHES BY TO THE NORTH AND DYNAMICS ARE FAVORABLE. THE STRONGEST THREAT FOR SHOWERS IS EXPECTED THIS EVENING AND MILD TEMPERATURES ARE FORECAST OVERNIGHT AS PW REMAINS AROUND 1 INCH WITH PLENTIFUL CLOUD COVER. THE JET STREAM SHIFTS SLIGHTLY NORTHWARD THIS WEEKEND WITH A RISE IN H5 HEIGHTS. THE MOISTURE PLUME WILL ALSO SHIFT SLIGHTLY TO THE NORTH THIS WEEKEND. THE BIGGEST TEMPERATURE RESPONSE WILL OCCUR SUNDAY AS MIXING DEPTH INCREASES AND THE AIRMASS DRIES SOMEWHAT. MODELS IN REASONABLE AGREEMENT THRU THE WEEKEND AND USED THE SREF FOR THE WIND GRIDS IN THE SHORT TERM. MODEL HAD BEST DECOUPLING AND MOST REALISTIC WIND SPEEDS BASED ON CLIMATOLOGY. KEPT SLIGHT CHC OF SHOWERS AND THUNDERSTORMS IN THE EXTREME NORTH LATE SUNDAY AS AIRMASS DESTABILIZES AND MOISTURE IS STILL ADEQUATE ALONG THE IDAHO BORDER. .LONG TERM...SUNDAY NIGHT THROUGH NEXT FRIDAY. LATEST LONG RANGE MODEL COMPARISON FAVORS CONTINUING WITH AN ECMWF SOLUTION THROUGH THE END OF NEXT WEEK. THE CURRENT LONG WAVE PATTERN INDICATES A STRONG UPPER RIDGE OVER THE FOUR CORNER STATES WITH A SEMI-PERMANENT TROUGH POSITIONED IN THE VICINITY OF THE GULF OF ALASKA. IN BETWEEN THESE TWO FEATURES IS A STRONG WEST TO SOUTHWEST FLOW WITH AN EMBEDDED WEAK SHORT WAVE AFFECTING MAINLY THE NORTHERN PORTION OF THE CWA EARLY IN THE LONG TERM. THIS SHORT WAVE WILL BE LIFTING ACROSS IDAHO RESULTING IN SOME SHOWERS/TSTMS ACROSS NORTHERN HUMBOLDT AND ELKO COUNTIES SUNDAY NIGHT INTO MONDAY. AS THIS WEAK SHORT WAVE LIFTS TO THE NORTHEAST...THE UPPER FLOW GRADUALLY BECOMES SOUTHWEST WITH H5 HEIGHTS INCREASING TO 582-590DM NORTH TO SOUTH RESULTING IN DRY AND WARM CONDITIONS LATE MONDAY NIGHT THROUGH TUESDAY. BOTH THE GFS/ECMWF SUGGEST A RETURN TO THE SPRING PATTERN THAT HAS KEPT THE CWA COOLER THAN NORMAL WITH A STRONG UPPER TROUGH DIGGING INTO THE PACIFIC NORTHWEST AND ACROSS THE GREAT BASIN FOR THE MIDDLE AND END OF NEXT WEEK. THE COOLING ALOFT WILL COMBINE WITH AFTERNOON HEATING AND MOISTURE TO ENHANCE PRECIPITATION CHANCES ESPECIALLY ACROSS THE NORTHERN PORTION OF THE CWA DURING THE MIDDLE AND END OF NEXT WEEK. && .AVIATION...SCATTERED SHOWERS AND POSSIBLY A THUNDERSTORM WILL AFFECT MAINLY HUMBOLDT AND ELKO COUNTIES WITH PATCHY MVFR CIGS IN ADVANCE OF A WEAK COLD FRONT THROUGH THIS EVENING. THE CURRENT CLOUD COVER HAS INHIBITED THE STRONGEST WINDS ALOFT FROM REACHING THE SURFACE. HOWEVER SOME WIND GUSTS OF 35 TO 40 MPH CAN BE EXPECTED THROUGH THIS EVENING BEFORE DIMINISHING. OTHER THAN AN ISOLATED SHOWER ACROSS THE NORTH...VFR CONDITIONS WILL PREVAIL FROM LATER THIS EVENING THROUGH SATURDAY. && .FIRE WEATHER...MAIN MESSAGE NEXT COUPLE DAYS IS GRADUAL DRYING TREND AND WARMING TEMPS. PACIFIC MOISTURE PLUME IS STILL A PLAYER INTO NEXT WEEK AND MAY DROP DOWN INTO EXTREME NRN NV AGAIN LATE MONDAY WITH ANOTHER CLIPPER TROF TO OUR NORTH. NEXT SIGNIFICANT SYSTEM WILL MOVE INLAND WEDNESDAY AND INCREASE WINDS AND BRING MORE SHOWERS AND THUNDERSTORMS BY THURSDAY. DRYING OF FUELS WILL ACCELERATE EARLY IN THE WEEK ESPECIALLY ACROSS CENTRAL NV...BUT THE NEXT STORM LATER IN THE WEEK COULD BRING MORE PRECIP. LOOK FOR GOOD RH RECOVERY TONIGHT AND LESS RECOVERY THE NEXT COUPLE NIGHTS AFTERWARD. && .HYDROLOGY...AREA RIVERS CONTINUE TO RISE WITH THE MARYS RIVER...JARBIDGE AND LAMOILLE CREEK IN MONITORING STAGE. LAMOILLE CREEK AND JARBIDGE RIVER MAY REACH THE MINOR FLOOD STAGE MARK LATE THIS EVENING OR OVERNIGHT.
