The Washington Cascades will continue with below normal temperatures and below normal precipitation through at least 2-14-2019. This is from troughs of low pressure that drop down from the north and bringing cold air into our region. Then the troughs set up off our coast and this will some snowfall to our region. I'm not seeing any big changes through 2-18-2019 as below normal temperatures continue.
