AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE RENO NV 300 AM PST THU DEC 22 2005 .SHORT TERM... SHOWERS CONTINUE TO COME OVER THE SIERRA AND INTO THE LEESIDE VALLEYS EARLY THIS MORNING BEHIND LAST NIGHTS HEAVY RAINS. CURRENT RADAR MOSAIC SHOWS A DECREASE IN SHOWER ACTIVITY OVER THE CENTRAL VALLEY WITH THE NEXT BAND OF PRECIP BEGINNING TO MOVE ONSHORE. EXPECT A BRIEF LULL IN THE PRECIP THIS MORNING BEFORE PICKING BACK UP THIS AFTERNOON AS THE NEXT WAVE MOVES INTO THE PACNW. THIS WAVE CURRENTLY SHOWS UP WELL ON WATER VAPOR IMAGERY AROUND 40N 140W WITH PLENTY OF MOISTURE AHEAD OF IT AND TAPPED INTO IT. MODELS CONTINUE TO GENERATE RATHER SIGNIFICANT QPF OVER THE SIERRA AND EXTREME WRN NEVADA BUT FEEL THAT THEY CONTINUE TO UNDERDO SUCH A MOIST AIRMASS. HOWEVER... THE DYNAMICS AND FORCING ASSOCIATED WITH THIS WAVE ARE NOT AS STRONG AS LAST NIGHTS SYSTEM...SO RAINFALL IS NOT EXPECTED TO BE AS IMPRESSIVE. SNOW LEVELS CONTINUE TO BE VERY HIGH SO ALL RAIN IS EXPECTED EXCEPT OVER THE HIGHEST PASSES. THE SATURATED GROUND CONTINUES TO BE PROBLEMATIC SO WILL EXTEND THE SMALL STREAM AND URBAN FLOOD ADVISORY THROUGH THIS EVENING TO COVER THE THREAT OF LOCALIZED FLOODING LATER TODAY. SHOWERS LINGER OVERNIGHT TONIGHT MAINLY OVER THE MOUNTAINS AS RIDGE BEGINS TO BUILD BACK INTO THE WEST COAST. AS HEIGHTS CONTINUE TO RISE FRIDAY ALL SHOWER ACTIVITY WILL BE PUSHED INTO THE NRN SIERRA. TEMPERATURES WILL REMAIN MUCH ABOVE NORMAL FRIDAY AND SATURDAY. WITH SO MUCH LOW LEVEL MOISTURE AS THE RIDGE BUILDS IN...THERE IS SOME CONCERN FOR FREEZING FOG FRIDAY NIGHT BUT LEFT OUT ANY MENTION AT THIS TIME AS IT IS EXPECTED TO REMAIN LOCALIZED TO THE MOST FOG PRONE AREAS. THE RIDGE BEGINS TO BREAK BACK DOWN SATURDAY NIGHT AS ANOTHER TROUGH MOVES ONSHORE. JORDAN .LONG TERM...SUNDAY THROUGH WEDNESDAY... WITH THE LACK OF A LONG WAVE TROUGH OVER THE EASTERN UNTIED STATES...PROGRESSIVE PATTERN IS LIKELY TO CONTINUE THROUGH MID WEEK. NEXT SYSTEM SHOULD HIT THE SIERRA ON SUNDAY NIGHT OR EARLY MONDAY MORNING AND CONTINUE THROUGH MONDAY NIGHT. BUMPED POP UP A BIT HIGHER AND SHOULD SEE POPS IN THE LIKELY CATEGORY IF MODEL CONSISTENCY HOLDS. THIS SYSTEM MAY BE A BIT COOLER WITH SNOW LEVELS LOWERING TO 7000 FEET. THAT WOULD CUT DOWN ON THE AMOUNT OF RUNOFF...BUT WITH SATURATED SOILS BELOW 7000 FEET IN THE SIERRA AND ALONG THE SIERRA FRONT MINOR FLOODING AND ROCK SLIDES WILL STILL BE AN ISSUE. MODELS ARE HINTING AT A FLATTER RIDGE FOR TUESDAY...AHEAD OF THE NEXT SYSTEM WHICH COULD ARRIVE ON TUESDAY NIGHT/WEDNESDAY MORNING. STRENGTH OF THE RIDGE WILL DETERMINE THE TIMING...WITH A FLATTER RIDGE YIELDING A FASTER ARRIVAL TIME. BRONG && .AVIATION... MINIMAL IMPROVEMENTS TO CEILINGS TODAY...ESPECIALLY ALONG THE SIERRA WHERE MVFR CONDITIONS WILL CONTINUE. BRONG && .REV WATCHES/WARNINGS/ADVISORIES... .NV...URBAN SMALL STREAM FLOOD ADVISORY NVZ002-003 UNTIL 9 PM THU. .CA...URBAN SMALL STREAM FLOOD ADVISORY CAZ071-072 UNTIL 9 PM THU. &&
