245 AM PST SUN MAR 24 2002
THE UPPER LEVEL LOW CENTER OVER NORTHEAST OREGON AND CENTRAL IDAHO
REMAINS IN PLACE THIS AFTERNOON. IT IS SLOWLY WEAKENING...BUT AREAS
OF ENHANCED CLOUD CONTINUE TO DEVELOP IN IDAHO...JUST EAST OF
WALLOWA COUNTY. PRECIP RATES ARE STILL EXPECTED TO DECLINE SLOWLY
OVERNIGHT...BUT VISIBLE SATELLITE IMAGERY INDICATES SOME CONVECTIVE
CLOUDS IMBEDDED WITHIN THE GENERAL CLOUD COVER. THUS HAVE UPGRADED
THE SNOW ADVISORY TO A HEAVY SNOW WARNING FOR THE REST OF TODAY AND
TONIGHT. PRECIP HAS BEEN PERSISTENT AND AT TIMES MODERATE IN THE
BLUE MOUNTAINS...BUT SO FAR SNOW ACCUMULATIONS HAVE BEEN BELOW
ADVISORY LEVELS. EXPECT FURTHER SNOWFALL THIS EVENING TO AGAIN
REMAIN BELOW ADVISORY LEVELS THERE. A WAVE MOVING ON TO THE OREGON
COAST HAS SO FAR NOT DONE MUCH WEST OF THE CREST...BUT DO FEEL THAT
THIS WAVE MAY GET SOME SHOWERS GOING ALONG THE OREGON CASCADE EAST
SLOPES THIS EVENING. SHOULD SEE A GRADUAL WIND DOWN OF PRECIP IN THE
BLUE MOUNTAIN FOOTHILLS AND ONLY SOME DIURNAL SHOWERS ELSEWHERE.
WEAK RIDGING TO BUILD IN MONDAY TO FINALLY DRY THE AREA OUT AND TO
ALLOW SOME WARMING OF TEMPS WHERE IT HAS RAINED ALL WEEKEND. A WEAK
WAVE WILL APPROACH THE AREA TUESDAY AFTERNOON. THIS WAVE MAY CREATE
ENOUGH INSTABILITY FOR A FEW SHOWERS OVER THE CASCADE EAST SLOPES.
GKH
EXTENDED...A BROAD AREA OF HIGH PRESSURE...LOCATED EAST OF THE
OREGON COAST ON WEDNESDAY WILL BE THE DOMINATING INFLUENCE IN THE
WEATHER FOR THE FIRST HALF OF THE EXTENDED PERIOD AS THE SKIES
BECOME PARTLY CLOUDY. HOWEVER...A WEAK LOWER LEVEL SHORT WAVE TROUGH
WILL MOVE THROUGH NORTH CENTRAL WASHINGTON WEDNESDAY AND WILL
PRODUCE ISOLATED SHOWERS FOR THE EASTERN SLOPES OF THE CASCADES.
ALSO... UPSLOPING WINDS COMBINED WITH MODERATE AMOUNTS OF MOISTURE
IN THE LOWER LEVELS WILL PRODUCE ISOLATED SHOWERS OVER THE MOUNTAINS
OF EASTERN OREGON. ON THURSDAY AND FRIDAY...THE RIDGE WILL INTENSIFY
OVER THE REGION PRODUCING MOSTLY SUNNY TO PARTLY CLOUDY SKIES AND
WARMER TEMPERATURES ACROSS THE REGION. A COLD FRONT WILL DROP TO THE
SOUTH FROM CANADA FOR THE WEEKEND AND WILL BRING COOLER TEMPERATURES
AND A CHANCE FOR MORE PRECIPITATION. HENRY.
