________________
An Upper Level Low Pressure Trough will be cooling us down a bit with more clouds. We are still dryer than normal and below where we were at this time last year. We need rain, but the most we’ll see for the next week or so will be a drop-in-the-bucket compared to what we need. This could be a very bad fire season approaching. The graphics for days 1-3 show the front that will move in Friday. The graphics for days 3-7 show the frontal activity in the Pacific Northwest Saturday and Sunday.
