The Willamette Valley is under a Red Flag Warning through Wednesday evening due do dry weather and some gusty winds. The warning ends by Thursday morning, but a heat advisory begins Thursday afternoon and continues until Friday night due to another round of toasty temperatures.

Winds will be offshore and really boosting those highs. Come Friday, highs should drop by a few degrees—but not many. Temperatures Friday afternoon are likely to reach the lower 70s. On Sunday clouds are a bit more common, especially for the morning hours with temperatures warming to the mid 60s by the afternoon.
A Red Flag Warning will take effect across the Umpqua Valley Thursday morning and last until the evening hours. Temperatures will be hot, the region will be dry and winds will gust in the afternoon. The combination of these three things create prime fire conditions. Temperatures Thursday afternoon will warm to about 100 degrees for many spots.
