The City of Spokane isn’t the only one saying it (see thread below), the WSDOT agrees; it’s definetely winter. This picture from Snoqualmie Pass confirms it.
Snow piling up on the west slopes of the Cascades forced closure this morning of the uphill eastbound lanes on the pass. Apparently there were several slide offs making it too dangerous to travel the pass. Things are moving again, although it looks like slowly. Here are traffic cameras from the Pass if you want to keep an eye on how things are moving there.
