Weekend and Next Week

Friday, September 23, 2011
7:16 P.M.

Hi everybody. As expected, the forecast for Monday has changed... again. I'm going to refrain from posting too much detail about it as it will probably change again. The models usually have a pretty hard time during the fall!

Meanwhile, we had a nice warm day today. I said in an earlier post that we would not have an 80 degree day until spring next year. I was wrong. We got up to 80 degrees in Seattle, I'm not sure about the airport, but it could have been warmer. I guess it could have been colder too, though.

Saturday will also feature warm temperatures, and I think we will get up to 80 degrees again. However, it will feel even warmer than that because we will also be fairly humid. This won't be anything like east coast humidity, but it will feel a little sticky tomorrow. This is because we will have a southerly flow, as opposed to the typical drying, easterly flow that we typically associate with heat waves.

The graphic below shows the temperatures predicted at 5 P.M. tomorrow. You can see mostly high 70s throughout the area with warmer temperatures in eastern Washington and cooler temperatures closer to the coast.

 Valid 05:00 pm PDT Sat, 24 Sep 2011 - 36hr Fcst - UW 4/3km 12z WRF-GFS surface temperature

One note - we could see a few isolated thunderstorms in the Cascades late tomorrow. This often happens when we have a southerly flow in the summer/fall.

College calls, thanks for reading!
