 .SHORT TERM...
 
 UPPER RIDGE CONTINUES TO PUSH INTO THE GREAT BASIN...WITH SOME 
 EXTREMELY DRY AIR ALOFT. SLIDE MOUNTAIN DEW POINT STILL SITTING 
 AROUND -35F. TO PUT THAT IN PERSPECTIVE...EVEN AT 32 DEGREES AT THE 
 TOP OF SLIDE...THAT RELATIVE HUMIDITY IS ONLY 3-4 PERCENT. EXPECTING 
 700MB TEMPS TO INCREASE TODAY TO 2-3C...WITH HIGH TEMPS HITTING THE 
 LOW 60S TODAY ACROSS THE LOWER VALLEYS AND LOW 50S IN THE SIERRA 
 VALLEYS. SHOULD SEE SEVERAL DEGREES WARMER ON TUESDAY...AS WE GET 
 INCREASED SOUTHWEST FLOW.
 
 A SHORTWAVE TROUGH WILL PASS TO THE NORTH OF OUR AREA ON 
 TUESDAY...MOVING INTO THE PAC NW BY TUES NIGHT. THIS WILL HELP TO 
 FLATTEN OUT THE RIDGE AND INCREASE THE SOUTHWEST WIND FLOW ALOFT. 
 MODELS HAVE INDICATED SOME MEAGER INSTABILITY OVER THE LAST SEVERAL 
 RUNS..LIFTED INDEX 0 TO -1C. COULD SEE SOME ISOLATED SHOWERS ON WED 
 AFTN...BUT WITH LIMITED MOISTURE AND DRY BOUNDARY LAYER...MAY NOT 
 SEE MUCH MORE THAN VIRGA. EVEN THE SREF IS STARTING TO HINT AT THE 
 WED CONVECTION. DID BUMP UP POPS AND ADD A SLIGHT CHANCE OF SHOWERS 
 TO THE FORECAST FOR TAHOE AND MONO. IF THIS WAS APRIL...WOULD BE 
 THINKING MORE ALONG THE LINES OF THUNDERSTORMS WITH THOSE LIFTED 
 INDICES...BUT FOR NOW WILL THUNDER OUT OF THE FORECAST.  HOON
 
 .LONG TERM...THURSDAY THROUGH SUNDAY...
 
 FEW CHANGES. SHORTWAVE STILL PROGGED TO BE PASSING SWD THRU THE 
 GREAT BASIN WITH MODELS CONTG TO INDICATE ENOUGH INSTBY AND LGT QPF 
 SIGNATURES TO WARRANT THE SLGT CHC OF SHOWERS MAINLY SRN/ERN ZNS. 
 ACTIVITY MAY BEGIN AS FAR NORTH AS ERN PERSHING/CHURCHILL COUNTIES 
 IN THE MRNG BUT QUICKLY MOVE TO SRN COUNTIES OF MONO/MINERAL AS DRY 
 NLY FLOW ON SYSTEMS BACK SIDE PUSHES INSTBY SWD. OTHERWISE MUCH 
 DRIER AIR PUSHING ACRS RGN THU NGT-FRI WITH AMS UNLIKELY TO RECOVER 
 MUCH OVR THE WEEKEND. JUST AS DEWPOINTS SHOW SOME SLIGHT MODERATION 
 SAT NGT...A DRY SWLY FLOW SETS UP AHD OF NEXT PAC TROF ON SUN. 
 
 MODELS CONT TO SHOW TROF LATE WEEKEND INTO EARLY NEXT WEEK. THE 
 ECMWF WAS A BIT SLOWER WITH MAIN SYST PASSAGE NOW LATE SUN NGT-MON 
 WHICH WAS IN LINE WITH THE DETERMINISTIC GFS. ALTHOUGH THE GFS WAS A 
 BIT FLATTER AND NORTH WITH TRACK. THE CANADIAN WAS CLOSER TO THE 
 ECMWF TNGT. BOTTOM LINE...ANOTHER DAY OR TWO IS GOING TO BE NEEDED 
 TO BETTER PINPOINT IMPACTS AND TIMING. FCST WL CONT TO REFLECT LOW 
 POPS ACRS THE NORTH BEGINNING SUN NGT WITH INCRG WINDS SUN AFTN-SUN
