First Tornado Watch

By Dan ( April 1, 2007 at 1:04 pm) · Filed under General

We had the first tornado watch of the season yesterday; ended up busting. Just had a spit of rain for about 2 minutes and that was it.

Looking ahead the models are showing a quiet period settling in until around April 15th or so. Hopefully we can get into a more active pattern and avoid what we had in 2005 & 2006.
