Timing Of Strong/Severe Storms

Posted on: 9:30 am, April 17, 2013, by

It’s that time of year. Whenever a strong cold front approaches the Tennessee Valley, the potential for severe weather exists. Late Thursday into Friday is the time frame we’ll keep a close watch on. The Storm Prediction Center has a portion of the Tennessee Valley under a *slight risk* of severe storms ending at 7am Friday morning. After that time, areas east of I-65 have the chance of strong, damaging winds and large hail. Everything should be over my lunch time on Friday.

Here is one of our inhouse computer models showing a band of heavy rain pushing through early Friday morning. The yellow and orange colors represent stronger storms. Any of those storms could go severe. Right now, the tornado threat is very low. Behind it, temperatures cool off as highs won’t get out of the lower 60s for the afternoon.

We’ll have to watch the temperature very closely on Saturday and Sunday mornings. Readings are likely to drop into the middle to upper 30s both mornings. Wind could stay up enough to keep frost from forming early Saturday, but Sunday will be different. As high pressure settles in, winds are likely to go “calm.” A clear sky and calm allows the temperature to drop even further. Some of the colder valleys are likely to dip to near freezing Sunday morning. Be ready to cover all tender vegetation this weekend!
