It will be associated with a very sharp upper-level trough, causing rapid pressure falls and strong wind fields over Alabama, with winds increasing significantly by late morning and afternoon. Some non-thunderstorm wind gusts over 40 mph... Continue reading

A lot of people have been asking me whether or not it will be a cold winter, and whether or not it will snow. On the latter question, I have no idea. So many things have to come together that it's impossible to predict that more than a week out.... Continue reading

It happened on my car when it first got cold, then my mother called me today and asked "Why do I have a low tire pressure warning light on"? This light has come on for a lot of people in the past two weeks. You may have a leak in... Continue reading

Since people will probably start talking about the "polar vortex" again soon, as if it were some rare atmospheric phenomenon like a tornado or a hurricane, I thought it would be good to write a blog about what it is and what it is not. According to the "Glossary of... Continue reading

The above chart shows a computer model prediction for temperatures in Birmingham through this weekend. I think this model is probably the closest to what will really happen. On Ooctober 16 on this blog I said, "I will miss days in the 80s". I mentioned that a few days with... Continue reading

I circled the storms of most concern right now. It's often these isolated cells out ahead of the main line of storms that produce tornadoes. Tornado warnings are in effect for the 2 northern ones in Marion County, and in Lauderdale, Colbert, Franklin counties. It seems like the greatest risk... Continue reading

However, we at Fox 6 received a lot of viewer pictures like the one above as storms moved through Cullman between 530 and 630 pm. Is that just... Continue reading
