Extended Outlook Cascades

Issued: May 16, 2016 Forecast models are starting to suggest that the weather patterns for the Washington Cascades change especially for the period of May 23 to May 29 as temperatures will be below normal and precipitation above normal. The 500 mb map (at 18,000 feet) below confirms that pattern as the map below indicates a trough of low pressure off  Northwest  coast.
