Moderate Risk

This morning the Storm Prediction Center in Norman, OK, issued a Moderate Risk of Severe Weather for Northern LA and Central/Southern MS.  This area includes Areas west of I-59, but this is still a concern to areas east of I-59.  A Moderate Risk from the SPC means there is a 15% chance of a tornado occurring within a 25 mile radius of any point within the Risk Area.  A moderate risk is not issued very often so please stay tuned to our updates for more information.  My thoughts agree with this forecast from SPC, but we won't start experiencing severe weather until this afternoon and into this evening.  I expect the main cold front and squall line to move through around midnight tonight, but my greatest concern is what could happen before the front moves through.  As we will have a moderate to large amount of instability and dynamics for severe thunderstorms to develop south of I-20.  If you walk outside, you know there is more moisture in the air, which isn't normal, and this moisture will be a prime variable in creating thunderstorms this afternoon and into the evening.  Please stay tuned to this blog throughout the afternoon and evening.  We will go on-air this afternoon/evening/night if our viewing audience is at risk of severe weather.  tcade@wdam.com
