AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE RENO NV 310 AM PDT SUN SEP 19 2004 .SHORT TERM... STRONG EASTERN PACIFIC JET MAXIMA CONTINUES TO FORCE COLD AIR/UPPER TROUGH SOUTHWARD INTO CALIFORNIA THIS MORNING WITH LIGHTNING NEAR THE NORTHERN CALIFORNIA AND OREGON COASTLINE INDICATIVE OF THE ASSOCIATED DEPTH AND INSTABILITY OF THIS SYSTEM. SOME OF THIS JET ENERGY IS EXPECTED TO ROUND THE TROUGH TODAY AND WORK ACROSS THE CENTRAL SIERRA. A COMBINATION OF DYNAMICS AND STEEPENING LAPSE RATES WILL ALLOW FOR SCATTERED SHOWERS TO DEVELOP...MOST NUMEROUS IN THE TAHOE BASIN INTO NORTHEAST CALIFORNIA THIS AFTERNOON AND EVENING. QPF IS EXPECTED TO REMAIN GENERALLY LIGHT WITH MUCH LOWER SNOW LEVELS ALLOWING SOME HIGHER ELEVATIONS TO RECEIVE AT LEAST A DUSTING OF SNOW AND PERHAPS AS MUCH AS A FEW INCHES IN LOCALLY HEAVIER SHOWERS. THE SNOW LEVELS WILL FALL CLOSE TO LAKE LEVEL ALTHOUGH ANY SNOW ACCUMULATION WILL LIKELY STAY CONFINED TO LOCATIONS ABOVE 7000 FEET. STEEP LAPSE RATES ASSOCIATED WITH H5 TEMPERATURES CLOSE TO -25C AND AFTERNOON HEATING WARRANTS ISOLATED THUNDER NORTHERN HALF TODAY. COLD UNSTABLE CYCLONIC FLOW WILL REMAIN OVER THE AREA AT LEAST INTO EARLY MONDAY AS TROUGH AXIS SWINGS EASTWARD INTO THE GREAT BASIN. SOME LINGERING SNOW SHOWERS WILL STILL BE POSSIBLE MONDAY.

FLAT RIDGE REDEVELOPS OVER CA-NV BY WED AND ALLOWS FOR A GRADUAL WARMUP TO NEAR NORMAL TEMPS BY THUR WITH TEMPS PEAKING IN THE LOWER 80S IN THE WRN NV VALLEYS FOR FRI-SAT. SOME OF THE MEDIUM RANGE MODELS INDICATE A WEAK UPPER LOW OFF THE NORTHERN CA COAST FROM THUR-SAT WHICH COULD INCREASE AMOUNT OF HIGH CLOUDS OVER THE FORECAST AREA...BUT POSITION OF THIS LOW WOULD BE TOO FAR AWAY TO PRODUCE UNSTABLE CONDITIONS OR PRECIP OVER THE REGION. SKY FIELDS WERE INCREASED TO PARTLY CLOUDY OVER MOST AREAS FOR THUR AND SAT IN GENERAL AGREEMENT WITH GFS 500-300 MB RH LAYER. MJD && .REV WATCHES/WARNINGS/ADVISORIES... NV...NONE. CA...NONE. &&
