DISCUSSION
RADAR SHOWS LIGHT SNOW SHOWERS ACROSS THE CASCADES
AND PARTS OF THE NORTHERN BLUE MOUNTAINS THIS AFTERNOON.
PRECIPITATION WILL CONTINUE TO DISSIPATE AS WE THROUGH THE
LATER AFTERNOON HOURS WITH CLEARER, DRIER CONDITIONS MOVE IN.
LOW TEMPS WILL DROP BELOW FREEZING AS A RESULT DUE TO THE
EFFECTIVE RADIATIVE COOLING OVERNIGHT. WINDS WILL CONTINUE TO
STAY IN THE 10 TO 20 MPH RANGE WITH LIGHTER WINDS IN THE LATER
MORNING HOURS.
SYNOPTICALLY, WE'LL SEE A LOW PRESSURE MOVE INTO CALIFORNIA,
WITH A SECONDARY AREA OF LOW PRESSURE JUST TO THE NORTH. THIS
WILL BRING ON A SLEW OF SHORTWAVES IN THE AREA, MAKING WAY FOR
SOME LIGHT MOUNTAIN SNOW PRECIPITATION THROUGH THE WEEK. NOT
ANTICIPATING ANYTHING SIGNIFICANT AS MOST OF THESE SHOWERS WILL
BE LIGHT IN NATURE. OUR NEXT WEATHER MAKER WILL ENTER THE AREA
AROUND SATURDAY, WITH A TROUGH DIGGING DOWN IN THE PACNW REGION,
BRINGING AMPLE SW FLOW ALOFT AND MOISTURE ADVECTION. AN
ONSLAUGHT OF LIGHT RAIN TO LIGHT SNOW SHOWERS WILL DEVELOP, WITH
CHANCES OF RAIN INCREASING, WITH LOW CONFIDENCE (5 TO 15
PERCENT) OF A GLAZE OF SNOW DEVELOPING. FURTHER DOWN SOUTH INTO
CENTRAL OREGON, A CHANCE OF SNOW SHOWERS IS HIGHER (15 TO 25
PERCENT CHANCE) WITH UP TO AN INCH POSSIBLE THROUGH MONDAY. MOST
OF THE MODERATE TO HEAVY SNOW WILL BE SECLUDED TO THE MOUNTAIN
REGIONS, ESPECIALLY IN THE CASCADES AND NORTHERN BLUE MOUNTAINS.
CURRENT NBM VALUES BRING TOTALS AROUND 5 TO 8 INCHES, WITH SOME
LOCAL SPOTS GETTING 10+ INCHES. A SERIES OF ADVISORIES AND
POSSIBLY A WARNING FOR WINTER WEATHER IN THE CASCADES AND/OR
NORTHERN BLUE MOUNTAINS MAY BE NEEDED HEADING CLOSER TO THE
EVENT, BUT WILL NEED TO MONITOR THE TREND BETWEEN NOW AND THE
NEXT FEW DAYS. REGARDLESS, DRIVERS SHOULD PREPARE FOR MODERATE
TO HEAVY SNOW FOR PORTIONS ACROSS THE CASCADES AND NORTHERN BLUE
MOUNTAINS AS WE HEAD INTO THIS WEEKEND.
