EUGENE, Ore. -- Happy Labor Day! With Labor Day being the unofficial start to Fall, I think it best to recap the month of August and give a preview what we can expect this fall. August saw nearly 30-degree difference between the hottest day and coolest day. The coolest days were back on August 7 and 8, when we reached 72 degrees, while hottest was 101 on August 27, during our heat blast. The month also solid shot of rain on August 21, when we receive anywhere from 0.2 to 0.75 inches of rain depending on where you live. Despite that, we still end the month down -0.05 inches in Eugene. Roseburg ended the month up 0.61 inches, as they had the August 21 rain and thunderstorms back on August 10. Unfortunately the official rain gauge at the Southwest Oregon Regional Airport in North Bend is broken, so we do not of solid account of rainfall at the coast this past month.
Moving forward over the next three months, the NOAA Climate Prediction Center is predicting a 40% chance of above normal temperatures in the Pacific Northwest. They also predict equal chances of above or below precipitation. The Climate Prediction Center also believes that drought conditions will like persist across Northwestern Oregon through at least November.

This week a couple of shortwaves will be moving through the region, which play a significant role to the weather pattern in the Pacific Northwest. The first one is lifting north and will merge with an area of low-pressure off the Washington coast. This bring more onshore flow today and tomorrow. This will keep clouds along the coast this morning before clearing this afternoon. Temperatures will remain near normal.
Tuesday into Wednesday will see some upper level ridging of high pressure, bringing more sun and above normal temperatures heading into the Wednesday. Though those warmer temperatures will not last as a low-pressure system will replace the ridge late Wednesday night. This will be the catalyst for thunderstorms in the Cascades on Wednesday and Thursday afternoons.
This weekend will see more sunshine of Friday and Saturday with high pressure overhead, though our next system will likely move in Sunday bring more clouds and cooler temperatures into next week.
