Forecast models continue to bring a ridge of high pressure at times over Washington state. See map below which is the average position of the 500 mb (about 18,000 feet). This is for the period 12-18 to 12-22 and indicates a ridge of high pressure over Washington. This type of pattern will bring below normal snowfall for the Cascades. La Nina is suppose to bring above average snowfall right? Generally yes however the biggest impacts of the snowfall usually come later in the winter, generally January and beyond.
