 .SHORT TERM...
 UPPER RIDGE BUILDING OVERHEAD IS BEGINNING TO BRING SUBSIDENCE
 WARMING TO THE SIERRA/WHITE MOUNTAIN RIDGETOPS...WITH OBS SITES
 ABOVE ABOUT 8500 FEET INDICATING WARMING ALONG WITH LOWERING
 HUMIDITIES. MEANWHILE...A 1028 MB SURFACE HIGH PRESSURE HAS BUILT
 INTO THE GREAT BASIN AND SET UP A NEGATIVE PRESSURE GRADIENT FROM
 THE CENTRAL VALLEY TO THE BASIN. THIS IS DRIVING EAST-NORTHEAST
 WINDS GUSTING OVER 60 MPH TO THE SIERRA CREST THIS MORNING. RIDGE
 WINDS SHOULD DIMINISH THIS AFTERNOON AND EVENING AS THE RIDGE
 ALOFT SETTLES DIRECTLY OVERHEAD.
 
 NOT MUCH TO DISCUSS THROUGH THE SHORT TERM...WITH AN UPPER RIDGE
 IN PLACE INTO TUESDAY. THE MAIN STORY WILL BE HIGHS WARMING TO
 ABOVE AVERAGE MONDAY AND WELL ABOVE AVERAGE BY TUESDAY ALONG WITH
 LIGHT WINDS AND PLENTY OF SUNSHINE. SNYDER 
 
 .LONG TERM...WEDNESDAY THROUGH SATURDAY...
 MODEL AGREEMENT WITH THE LARGE SCALE FEATURES IS BETTER THAN IN PREV 
 DAYS AND SUBSEQUENTLY CONFIDENCE IS HIGHER THIS MRNG. MAIN CHANGES 
 THIS MRNG WERE TO INTRODUCE ISOLD SHOWERS TO SRN AREAS THU AND LOWER 
 DEWPOINTS AND RH FRI-SAT.
 
 AT BEGINNING OF PD...S/W TROF MOVG THRU THE PACNW WL HELP PUSH A 
 BAND OF LOW-MID LVL MOISTURE SEWD INTO THE AREA. DAYTIME TEMPS WL 
 STILL BE PUSHING 10 DEGREES ABV NORMAL WITH INSTBY BLDG ACRS THE 
 BASIN AND RANGE AND ALG SIERRA. THE GFS SHOWS MORE INSTBY AND 
 LIGHTER WIND PROFILES ALG WITH SOME SPOTTY QPF LATE WED. HOWEVER 
 BELIEVE INSTBY MAY STILL BE TOO MARGINAL AND SIDED WITH THE ECMWF 
 WED WHICH MAINLY BRINGS SOME CLOUDS INTO AREA WITH A BIT MORE FLOW 
 IN THE MID AND UPR LVLS. THERE COULD BE SOME VIRGA SO LEFT GHOST 
 POPS IN GRIDDED DATA BASE. MODELS THEN SHOW S/W DROPPING SWD INTO 
 THE ERN GREAT BASIN LATE WED NGT-THU WITH THE ECMWF MOST AMPLIFIED 
 WITH FEATURE. BOTH DETERMINISTIC RUNS CONT TO INDICATE INSTBY FROM 
 MONO-MINERAL CO NEWD INTO CNTRL NV AND WITH LGT WIND FLOW AT TAIL 
 END OF S/W...MORE LIKELY TO SEE A FEW SHOWERS THU AFTN AND EARLY 
 EVENING. QPF IS GOING TO BE MEAGER AND GENERALLY ONLY A FEW 
 HUNDREDTHS. THE PROBABILITY FOR THUNDER IS VERY LOW AS MID LVL LAPSE 
 RATES ARE MARGINAL AND INSTBY SHALLOW. SOUNDINGS DO NOT INDICATE 
 ENOUGH MOISTURE OR SFC HEATING TO OVERCOME MID LVL WARM LAYER. 
 
 MUCH DRIER AMS WL REPLACE MOISTURE AND INSTBY THU NGT WITH BONE DRY 
 CONDS UNDER RDG FRI. ANOTHER S/W SYST BRUSHES AREA FRI NGT-SAT 
 MAINLY RESULTING IN SOME INCR IN WIND...ESPECIALLY AT UPR ELEVATIONS 
 IN THE NRN SIERRA. THE ECMWF SHOWS SOME LGT QPF ALG AND JUST NORTH 
 OF OR BORDER FRI NGT. HOWEVER BAND OF MOISTURE IS VERY NARROW AND 
 FAST MOVING. SO DO NOT EXPECT ENOUGH MOISTURE TO BE PRESENT TO 
 OVERCOME ANTECEDENT DRY AMS AND PRODUCE MEASURABLE PRECIP. MAYBE A 
 FEW CLOUDS. TEMPS COOL SLIGHTLY TWD END OF PD BUT WL REMAIN ABV 
 SEASONAL NORMALS FOR MID MARCH. HOHMANN
