Weather Washington Cascades- Extended Outlook

Issued July 10,2018

Starting this Wednesday July 11 and continuing through at least July 20 (see map below) an upper level ridge of high pressure will build. Thus dry conditions and above normal temperatures will be the rule. In fact many models keep this ridge in place through the end of July.
