TODAY THROUGH TUESDAY: A MILD, DRY SATURDAY IS EXPECTED AS A
WEAK RIDGE PATTERN IS OVER THE REGION BEHIND YESTERDAYS COLD
FRONT. HIGHS WILL REACH INTO THE 50S. IT WILL BE SHORT LIVED AS
ANOTHER LOW WILL SLIDE DOWN THE COASTLINE FROM BC TO OREGON
THROUGH SUNDAY. ENSEMBLES HAVE COME INTO BETTER AGREEMENT ON THE
TIMING AND TRACK. THE LOW WILL SLOWLY TRACK OVER OREGON THROUGH
MONDAY. IT HAS POTENTIAL TO BRING LIGHT SHOWERS ACROSS THE
INLAND NORTHWEST. THE AMOUNTS ARE NOT LOOKING TO BE MUCH AS
PRECIPITABLE WATER AMOUNTS STRUGGLE TO GET ABOVE HALF AN INCH.
THE DAILY 25-75 PERCENT PROBABILITIES ARE: 0-0.1 ON SUNDAY,
0.1-0.3 ON MONDAY, AND 0.05-0.2 (HIGHEST AMOUNTS OVER SOUTHEAST

AROUND 4500 FT. AN INCH OF SNOW IS POSSIBLE FOR THE HIGHER
ELEVATIONS. HIGHS WILL BE IN THE UPPER 40S TO LOW 60S. OVERNIGHT
LOWS WILL BE IN THE UPPER 20S AND 30S.
WEDNESDAY THROUGH FRIDAY: ENSEMBLES ARE INDICATING ANOTHER
SYSTEM PUSHING INTO THE REGION FROM THE GULF OF ALASKA. AGAIN,
THERE IS A LOT OF UNCERTAINTY ON THE TRACK OF THE LOW. AROUND 35
PERCENT OF MEMBERS HAVE THE LOW OVER THE PACIFIC NORTHWEST. THE
OTHER 65 PERCENT HAVE A MORE GENERALLY BROAD TROUGH PATTERN
OVER THE REGION. EITHER WAY, THERE IS NOT A LOT OF MOISTURE
ASSOCIATED WITH THE SYSTEM. IT WILL PUSH SOME COLDER AIR INTO
THE REGION. HIGHS WILL BE IN THE UPPER 30S TO LOW 50S. OVERNIGHT
LOWS WILL BE IN THE 20S TO LOW 30S. /JDC
