Valley Thunderstorms Today – Chasers Be Ready!
Are you ready for some exciting weather today? The latest models minted this morning are giving valley areas from Longview south to Eugene a pretty decent shot at thunderstorms anytime after 2pm today. Here is how it will all play out. This morning’s atmosphere is already quite unstable. The humidity is also quite high and temperatures are running in the lower 60’s as of 9:00 AM. We should top out somewhere around 80 degrees yet again today. As the afternoon heating continues, clouds will continue to build as the atmosphere continues to destabilize. Then conditions will become conducive for thunderstorm formation after 2:00 PM in the valley from Longview south to Eugene. In fact, here is the 12z WRF-GFS “CAPE” forecast (that’s a measurement of potential energy in the atmosphere) which shows a nice area of very unstable air in the valley later today —
The 12z MM5-NAM also concurs with a similar forecast —
At the same time, a marine push from the coast will flood into the valley which will add additional fuel the fire. So, if you’re looking for excitement in your weather, today may just be your day, especially if you are a storm chaser. Get those cameras ready after 3:00 PM and have fun.
Speaking of computer weather models, the Oregon Chapter of the American Meteorological Society (AMS) will host a GREAT meeting with a GREAT speaker, Dr. Cliff Mass from the University of Washington. This meeting will be at OMSI (Portland) on Saturday, May 12th at 10AM! This meeting is free and open to add ages of the public. Cliff will talk about advancements in weather forecasting and modeling, including some exciting updates that are coming for his very own WRF and NAM models run by the U of W. I have seen parts of this talk and you will definitely NOT want to miss this meeting if you are interested in weather at any level. The best part is, you can enter a raffle to win an amazing $300 Davis home weather station! For all the details on this meeting, see — http://www.columbian.com/weblogs/weat…
