Washington Cascades- Extended Outlook

Updated 4-1-2015

Most forecast models are bringing above normal precipitation through April 14 and the main reason is troughs of low pressure (see link to map below) will drop down from the northwest over the period. The major uncertainly in the  forecasts is if temperatures will be above or below normal. I would think they would tend to be below normal.
