An Upper Level High Pressure Ridge (Shaded “Arch” shape with blue arrows) was dry and warmer  for a short time at least. Now an Upper Level Low Pressure Trough (Shaded “U” shape with blue arrows) will send us more storms. The graphic for days 1-3 shows the frontal system moved in Tuesday and what’s coming next. The graphic for days 3-7 shows the next complex frontal systems that will be moving into Oregon Friday, next Monday and beyond. For mountain snow conditions at the local ski areas check out their websites or give them a call.
