More sunshine is expected across all the Pacific Northwest for the next few days. This sunshine, in combination with a touch of an off-shore airflow, will help to drive temperatures upwards. Highs should be in the 80s for most inland locations the next few days, and some spots—specifically to the south—will see +90 degree days.
On the coast, temperatures should be little cooler than inland spots but still warm for late September. Highs will stay mostly in the mid 70s, but any location with land to the north (such a Brookings) will see mid to upper 70s for our Wednesday and Thursday. The favorable wind direction will keep the marine layer form appearing in the morning, meaning skies will stay blue sunup to sundown. Temperatures should start to cool to more seasonable conditions on Friday, and this weekend might end with a few showers.
Inland areas are heading into some heat for the next couple of days. Thursday will likely end up warmer than Wednesday, but both days should be in the mid to upper 80s. Lower 90s are expected for areas father to the south like the Umpqua Valley. Clouds will be rare, and the few which do appear will only be high thin cirrus clouds. The next storm will begin impacting the region on Friday bringing cooler weather. Then on Saturday clouds will fill in and possibly some rain by Sunday.
