 .SHORT TERM...
 RIDGE OVERHEAD TO REMAIN NOW INTO MONDAY BEFORE A SPLITTING SYSTEM
 ARRIVES FOR TUESDAY. MODELS ARE IN GOOD AGREEMENT FOR THE NEXT 48 HOURS
 BUT CONTINUE TO DIFFER WITH THE SPLITTING TROUGH TUESDAY. AT THIS
 POINT, WILL LEAN TOWARD THE CONSISTENT EC SINCE IT HAS THE SUPPORT
 NOW OF THE GFS AND GEFS. THIS SOLUTION IS MAINLY DRY FOR OUR AREA
 WITH MORE ON THAT BELOW.
 
 AT LEAST FOR THE NEXT 48 HOURS UNDER THE RIDGE, THE FLOW ALOFT
 WILL BE VERY WEAK. STILL EXPECT ONY A FEW HIGH CLOUDS FOR INTO
 SUNDAY NIGHT WITH LIGHT WINDS. ANY WINDS WILL BE DRIVEN BY THE
 SURFACE GRADIENT WHICH WILL BE STRONGEST OVERNIGHT DUE TO
 RADIATIONAL COOLING. TEMPERATURES WILL CONTINUE TO HOLD STEADY AND
 NEAR NORMAL THROUGH MONDAY.
 
 BY MONDAY AFTERNOON INTO MONDAY NIGHT, CLOUDS WILL INCREASE AHEAD
 OF THE SPLITTING TROUGH. THEREFORE A MILDER NIGHT IS EXPECTED
 MONDAY NIGHT. THEN EC AND GFS KEEP THE SOUTHERN END OF THE SPLIT
 OFFSHORE AS IT MOVES SOUTHEAST TUESDAY. THE EC IS COMPLETELY DRY
 EVEN FOR THE SIERRA. THE GFS HAS ENOUGH MOISTURE TO BRING A FEW
 LIGHT SHOWERS TO THE SIERRA WITH SNOW LEVELS NEAR 6000 FEET. THE
 NAM IS AN OUTLIER SHOWING MOISTURE MAKING IT INTO WESTERN NEVADA
 WITH A 1/2 TO 3/4 INCH QPF. GIVEN THE UNCERTAINTY, LEFT THE
 FORECAST FOR TUESDAY ALONE EXCEPT TO HAVE A BETTER CHANCE OF
 PRECIP IN THE AFTERNOON COMPARED TO THE MORNING. WITH ABUNDANT
 CLOUD COVER NO MATTER THE SOLUTION AND WEAK WINDS ALOFT OVER THE
 AREA, TEMPERATURES WILL REMAIN NEAR NORMAL. WALLMANN
 
 .LONG TERM...WEDNESDAY THROUGH SATURDAY...
 COOLED DOWN HIGHS NEXT SATURDAY A FEW DEGREES, OTHERWISE LITTLE TO 
 NO CHANGE TO THE EXTENDED GRIDS. UPPER RIDGE TO BUILD IN WEDNESDAY 
 THROUGH FRIDAY WITH HIGHS RISING TO 5-10 DEGREES ABOVE AVERAGE FOR 
 THURSDAY AND FRIDAY. 
 
 THE ONLY THING OF NOTE TO DISCUSS WILL BE THE POSSIBLE APPROACH OF A 
 ELONGATING/SPLITTING DISTURBANCE MOVING INTO THE WESTERN CONUS AND 
 BRITISH COLUMBIA NEXT FRIDAY NIGHT AND SATURDAY. THE PROBLEM WITH 
 GETTING ANYTHING INTO OUR REGION WILL BE THE MEAN RIDGE OVER THE 
 WEST, WHICH WILL TEND TO TEAR APART AND WEAKEN ANY ENERGY TRYING TO 
 MAKE IT INLAND. THE ECMWF DOES NOT EVEN LET ANY ENERGY GET TO US 
 WITH THE SOUTHERN PART OF THE SPLIT GOING SOUTH WELL OFF THE 
 CALIFORNIA COAST WITH JUST SOME MID AND HIGH CLOUDS AT BEST BY 
 FRIDAY NIGHT AND SATURDAY. THE GFS IS MORE PROGRESSIVE AND BRINGS A 
 WEAK DISTURBANCE IN FOR LIGHT PRECIPITATION. 
 
 FOR NOW, I DO NOT BUY THE GFS AS IT TENDS TO BE TOO PROGRESSIVE AND 
 THE 12Z CANADIAN ENSEMBLE SPAGHETTI PLOTS SEEM TO SUPPORT THE IDEA 
 OF AN EARLY SPLIT OFF THE COAST SIMILAR TO THE 12Z OPERATIONAL 
 ECMWF. HOWEVER, EVEN THE ECMWF COOLS TEMPS ALOFT AND BRINGS IN 
 INCREASING HIGH MOISTURE/CLOUDS FRIDAY NIGHT AND SATURDAY. THEREFORE, 
 I COOLED DOWN HIGH TEMPS (ESPECIALLY RIDGES) ON SATURDAY AND ALLOWED 
 DRY RIDGE HUMIDITIES FROM EARLIER IN THE WEEK TO RISE WITH THE 
 COOLING ALOFT. SNYDER      
 
 .AVIATION...
 VFR CONDITIONS AND LIGHT WINDS WITH HIGH PRESSURE OVER THE SIERRA 
 AND WESTERN NEVADA THROUGH MONDAY. LOW CHANCE OF FOG AT TRUCKEE LATE 
 TONIGHT AND SUNDAY MORNING. HOWEVER, IT COULD JUST BE PATCHY NEAR 
 THE TERMINAL SO CONFIDENCE IS TOO LOW TO INCLUDE IN THE TERMINAL 
 FORECAST (ALTHOUGH I MAY GO WITH A BCFG TO COVER PATCHY FOG).
