THE EVENING AND OVERNIGHT, BRINGING ADDITIONAL SNOW TO THE HIGH
MOUNTAINS AND RAIN TO THE LOWLANDS. THIS PROGRESSIVE PATTERN WILL
CONTINUE TO BRING MOSTLY BENEFICIAL PRECIPITATION THROUGH THE REST
OF THE WEEK. SMALL CREEKS AND RIVERS MAY SEE SOME RISES,
PARTICULARLY PARADISE CREEK. WILL ALSO SEE SOME GUSTY WINDS AROUND
30-35 MPH IN THE BLUES, COLUMBIA BASIN, AND SPOKANE AREA MUCH OF THE

A PERIOD TO WATCH IS THURSDAY EVENING THROUGH FRIDAY IN THE CASCADES

PASS KEEP THE LIKELIHOOD OF 8 INCHES OR MORE MUCH LOWER AT 10%.
SUNDAY THROUGH TUESDAY: MODELS ARE STILL HINTING AT DRIER CONDITIONS
