________________

An Upper Level High Pressure Ridge is keeping the precipitation away, but it’s al;lowing late night/Early AM freezing fog. I got bitten by the Friday the 13th curse and instead of clouds and sun and warmer today the clouds and fog remained in the Eugene-Springfield area at the southern end of the Willamette Valley. The graphic for days 3-7 shows no slowdown in frontal systems that will be headed our way through next week. One storm on Wednesday and another between Saturday and Sunday. For mountain snow conditions at the local ski areas check out their websites or give them a call.
