…LOWLAND SNOW AND STRONG FRASER RIVER OUTFLOW WINDS POSSIBLE
SUNDAY AND MONDAY WITH COLD TEMPERATURES THROUGH EARLY NEXT
There is a threat of lowland snow showers across Western
Washington Sunday and Monday as a cool and moist weather system
tracks over the region. Snow levels will be close to sea level.
Given the showery nature of this system, snow amounts will not be
uniform across the region. However, heavy accumulations are
possible with stronger showers. Showers may decrease in coverage
on Monday as this system exits south of the area.
In addition, strong north to northeast winds are possible due to
Fraser river outflow. This typically affects western Whatcom
county and the San Juan Islands. Winds may peak early Monday
morning then gradually ease.
Expect cool temperatures Monday through Wednesday with highs only
in the 30s and lows in the teens to 20s. This is around 10 to 15
degrees cooler than normal.
