Overnight tonight temperatures will drop well below freezing for all inland areas with increasing clouds and areas of morning freezing fog in west side valleys. Fog may be dense and reduce visibility at times creating even more dangerous driving conditions than the already slick roads. Icy roads will be present the next few days, but starting tomorrow and into next week afternoon highs will climb above freezing, even for the east side which will help melt off the lingering snow and ice from last weeks’ storm. Air quality will begin to improve Thursday as a cold front moves in mixing up the atmosphere. Though high pressure will quickly build back in for the weekend which means air stagnation is likely again.

The cold front that’s arriving Thursday afternoon will bring mainly rain to the region and snow above 4,500 feet. East side areas and some areas of Siskiyou county will see a wintry mix of rain, snow and sleet. West side valleys in southern Oregon and northern California will mainly see rain, though there is the potential for localized areas of freezing rain. Any showers in the valleys will be light which means any areas that see freezing rain, ice accumulation should be minimal. But with already slick and icy roads, freezing rain will freeze on the surface and can create significant travel problems. Friday temperatures will struggle to cool to freezing so roads will be greatly improved Friday afternoon with continued improvement through the weekend with more melting.
More seasonal temperatures for this time of the year with warming 5 to 10 degrees above average into next week! Thanks for logging on and have a great evening ans stay warm!
