SNOQUALMIE PASS– It’s a cold start Thursday! Morning temperature readings in the teens, 20s and 30s are about 10-20 degrees colder than morning temperatures yesterday.
Heavy snow caused a headache for mountain pass travelers over the past 24-36 hours. Stevens Pass reopened early Thursday morning after a closure overnight. Traction tires are required there as of 7AM Thursday. Chains are required on Snoqualmie Pass for non all-wheel drive or four-wheel drive vehicles. And traction tires are advised to get over White Pass.
Officials with WSDOT sited multiple spin-outs from the snow and ice as the reason for two separate closures of the East Bound lanes of I-90 over Snoqualmie Pass Wednesday. Officials said many of the vehicles involved in the spinouts lacked the required chains or proper tires for winter driving weather.
Photos from Snoqualmie Pass yesterday afternoon:
This is why it's so important to follow the traction tire requirements and slow down. There are a number of vehicles spun out along EB I-90. It's currently closed EB at MP 47 just west of the summit. pic.twitter.com/6MoqW2zL9W

The snow level will climb to above the passes for most of the day. The cold front behind the next system will bring the snow level back down for Saturday and bring showers to the lowlands of the Mid-Columbia.
