.SHORT TERM...A FEW SPRINKLES STILL PASSING THROUGH OUR CWA EARLY
THIS MORNING.  BUT THE MAIN TROUGH...CURRENTLY IN WRN WA/OR...IS
FORECAST TO DIG SEWD TODAY AS IT MOVES FARTHER INLAND.  THE MAIN
PCPN IS FORECAST TO HIT NRN NEVADA WHILE LARGELY BYPASSING OUR CWA.
OUR ZONES NEAR THE NEVADA BORDER WILL GET RAIN SHOWERS...WITH SNOW
ABOVE 4500 FEET MSL...BUT SHOWERS WILL BE FEWER TO THE NORTH.
TROUGH WILL NARROW AS IT CONTINUES TO MOVE EAST...AND IT WILL TAKE
UNTIL NOON SUNDAY TO FINALLY GET EAST OF OUR CWA.  TROUGH WILL
STILL BE CLOSE ENOUGH TONIGHT FOR SHOWERS TO CONTINUE IN IDAHO
MOUNTAINS BUT THEY WILL GRADUALLY RETREAT EAST OVERNIGHT AND
SUNDAY MORNING.  WEST/NORTHWEST WINDS WILL INCREASE SUNDAY AS THE
TROUGH MOVES AWAY.  TEMPS WILL BE QUITE COOL TODAY AND TONIGHT BUT
MAX TEMPS WILL RISE ABOUT 5 DEGS IN IDAHO AND 10 DEGS IN OREGON
ZONES SUNDAY COMPARED TO TODAY.

.LONG TERM... SUNDAY NIGHT THROUGH SATURDAY. AN UPPER LEVEL RIDGE
WILL PROVIDE DRY WEATHER WITH MOSTLY CLEAR SKIES AND A WARMING TREND
THROUGH TUESDAY. HIGHS ON TUESDAY WILL BE 10-15 DEGREES ABOVE
NORMAL. MODELS SHOW THE RIDGE SHIFTING SOUTH AND EAST OF OUR AREA
AND WEAKENING WEDNESDAY AND THURSDAY...AND THEY AGREE ON WARM
SOUTHWEST FLOW ALOFT KEEPING TEMPERATURES ABOVE NORMAL...ALTHOUGH
THEY DIFFER ON HOW THEY HANDLE AN UPPER LEVEL TROUGH AS IT MOVES
OVER THE COAST ON THURSDAY. THIS TROUGH IS EXPECTED TO BRING SHOWERS
AND COOLER TEMPERATURES TO OUR AREA FRIDAY AND SATURDAY...BUT
INCREASING MODEL DIFFERENCES RESULT IN GREATER THAN AVERAGE
UNCERTAINTY IN TIMING...LOCATION...AND AMOUNTS OF PRECIPITATION.
