Daily Weather Charts
As a National Weather Service SKYWARN storm spotter, I like to keep a close eye on the weather, especially when severe weather is in the forecast. For those days, I created this web page, together with the larger Daily Weather Charts and the smaller micro version. The intent is to give me an amateur's "map room" for north Alabama. However, this is not a map room in the conventional sense, since it is not my intent to make a weather forecast. Instead, the purpose of this page is to answer these questions:
today a severe weather day?
If so, what, where and when?
feel free to copy and adapt this page to your needs.

How far out west do we need to be looking? The average cold front moves at about 30 MPH and can cover 720 miles in a day. By way of an example, the distance from Russell, KS, to Decatur, AL, is 722 mi. But a fast-moving cold front can travel at 60 MPH and can cover 1,440 miles in a day, and 720 miles in 12 hours. Again by way of example, the distance from Decatur to Salt Lake City is 1,424 miles and to Phoenix is 1,438 miles.
So as Storm Spotters, we sometimes need to be looking much further west than we might think. If I am looking at my weather pages at 6 AM, I'd need to be looking at the Kansas weather maps in order to see a fast-moving cold front that would arrive at 6 PM and I'd need to be looking at the Arizona and Utah maps in order to see a fast storm that could be here in 24 hours.
Mileages quoted are air miles (e.g, as the crow flies), based on a distance calculator located at http://www.infoplease.com/atlas/calculate-distance.html
