A BLOG ABOUT SOUTHWESTERN WEATHER, Welcome to the MadWeather Blog! We have two basic rules for this blog:
WEATHER FORECASTING & OBSERVING, AND OTHER RELATED TOPICS
(1) Debate and discussion should be civil.
(2) Because public discussion, regardless of the topic,
is not very effective if we don't know who is talking to whom,
MadWeather does not accept anonymous posts.
