Strong Storms Possible Overnight

By Jay Grymes & Steve Caparotta

We’ll be keeping both eyes on the advancing frontal system through the night.  Although widespread severe weather is not expected as the system rolls through the WAFB viewing area, we should be prepared for one or more severe weather Watches being posted between about midnight and 7AM, with isolated strong to severe storms potentially prompting some NWS Warnings. 
As with the Watches, the Warnings that are posted for WAFB communities are likely to be issued prior to sunrise.  Again, we don’t anticipate a large number of Warnings, but this system is rated by the NWS as a “Slight Risk” situation for severe weather.  The main severe threat will be straight-line winds but isolated Tornado Warnings cannot be rules out.

Fortunately, this line of storms looks to be a reasonably fast-mover, moving from west-to-east and clearing most (if not all) of the WAFB area by early to mid-morning.  By the afternoon, we expect clearing skies and cooler temps, with afternoon readings in the 60°s.

With the passage of tomorrow’s front, we’ll say goodbye to the recent run of days in the 70°s.  Temperatures will be cooler for the remainder of the work week, but they will be far from a true winter blast, even by Louisiana standards.  Thursday and Friday mornings will be chilly, with many neighborhoods waking-up in the 30°s, but only the northernmost WAFB communities can expect anything close to an early-morning freeze.  And with plenty of sunshine and afternoon temps climbing into the 60°s, there will be no complaining! 
(Actually, many of us might be happy with a good freeze or two to knock out the mosquitoes!)
This type of weather threat is a big reason why we promote NOAA Weather Radios.  Overnight storms, the ones that move over your neighborhood while you are sleeping, make the radio most valuable, alerting you to a severe weather threat before it arrives and catches you unprepared!
