An explanation of what is happening in the atmosphere over the coming day
Severe thunderstorm outlook.
Remember that a severe thunderstorm is defined as a thunderstorm that produces 60 mph winds or higher, quarter size hail or larger, and/or a tornado.
Wednesday night: Some storms could be severe. Heavy rain possible. High winds and hail possible.
Thursday: Severe weather is not anticipated.
Thursday night: A few storms are possible. It does not appear that severe weather is a concern, but monitor updates.
Frida and Friday night: Severe thunderstorms are possible. Heavy rain likely. Flash flooding concerns. Monitor updates. The greatest risk will likely be Friday afternoon and night.
Saturday and Saturday night: Saturday might end up mostly dry. Tough call. If storms were to form on Saturday then they could become severe. Storms are more likely Saturday night. Storms on Saturday night could produce heavy rain. I can’t rule out severe weather, but confidence is low.
Sunday and Sunday night: Storms are likely ahead of a cold front. Heavy rain possible. Some storms could be severe.

We have regional radars and local city radars – if a radar does not update then try another one. Occasional browsers need their cache cleared. You may also try restarting your browser. That usually fixes the problem. Occasionally we do have a radar go down. That is why I have duplicates. Thus, if one fails then try another one.
During the winter you can track snow and ice by clicking the winterize button on the local city view interactive radars.
If you have any problems then please send me an email beaudodson@usawx.com

There is a lot of noise on the internet. A lot of weather maps are posted without explanation. Over time you should learn who to trust for your weather information.
My forecast philosophy is simple and straight forward.
- Communicate in simple terms
- To be as accurate as possible within a reasonable time frame before an event
- Interact with you on Twitter, Facebook, email, texts, and this blog
- Minimize the “hype” that you might see on some television stations or through other weather sources
- Push you towards utilizing wall-to-wall LOCAL TV coverage during severe weather events
