As the calendar heads farther into September, the Northwest is starting to see the first signs of fall. The official first day of fall is not until September 23rd, 2016 and a freeze warning has been issued for some of the valleys across Northern Washington and parts of Idaho. With clearing skies and light winds, temperatures are expected to drop into the low 30s and even upper 20s in parts of the warning area. These temperatures pose a threat to any vegetation and gardens that are uncovered because it is still growing season. Not all areas will see these chilly temperatures as shown below in the graphic from the National Weather Service in Spokane, Washington. It is a sign that the summer nights are fading fast!
