Another Upper Level Low Pressure Trough (Shaded “U” shape with arrows) continues to control our weather with temperatures well below normal, but the snow seems to be staying in the mountains. The graphics for days 1-3 show the warm front moving in today and the cold front behind it Thursday. The graphics for days 3-7 show the disturbances headed toward the Pacific Northwest Sunday and a strong storm approaching the coast next Wednesday morning.
Note: It looks like Willamette Pass Ski, due to a lack of snow, is still not operating, but Hoodoo is open Wednesday through Sunday from 9 AM- 4 PM. Mt. Ashland is open and report all lifts are operating. They will also be open 9 AM until 4 pm March 24th through April 1st for Spring break. Check their websites for details on days of operation and ski conditions.
