An upper level high pressure ridge is getting stronger bringing dry weather. Wednesday was not as warm as expected in Eugene, but it will be much warmer today which will be well above normal for this time of the year and therefore we could set a new record high. A weak cold front slides in Friday just cooling us down a bit. A dry cold front will bring more cool air into the Pacific Northwest Saturday. Another weak frontal system brings just a slight chance of showers Monday and Tuesday. Then a better chance of showers Wednesday as another frontal system moves in Wednesday.
