Weather Washington Cascades: Extended Outlook

Issued 2-9-2016

The ridge of high pressure and warm and dry conditions that have recently been the theme over the Pacific Northwest will slowly start to change. We start to have some changes starting  this Wednesday and Thursday and more so over this weekend for new mountain snowfall especially for Friday and Saturday. New snow at about 4000 feet and above for Friday and Saturday.

However looking at the extended forecast the bigger changes start 2-18 to 2-19 as a trough of low pressure 500 mb map and associated cold air starts to move into the Pacific Northwest. 

Many are concerned on the snowpack in the Washington Cascades. Currently many areas are close to 100% of normal and this is the case even with the the recent dry and mild spell. Also for the months of November, December and January the Washington Cascades gets over 50% of it's snowfall. Given this data many experts still believe  our snowpack for this late spring  should be in good shape and not be below 80% of normal. Furthermore, experts are saying water from the mountain snow melt should meet our needs for this summer.  This can all change so stay tuned.
