As expected, the center of the cold core cut off low is right over the Heart of the Valley this afternoon bringing numerous showers and thunderstorms. Heavy rain, frequent lightning, and small hail occurred in many spots.
We also had several reports of funnel clouds. These are actually “cold air funnels”. These funnels are high based (meaning they develop well above the surface) with weak circulation that occur in a cool air mass. The cool and windy conditions in the lower troposphere mix with air in the middle troposphere that is flowing in a different direction to cause the rotation that spins up the funnel. These very rarely (but not never) touch ground or cause damage.
With rainfall totals over the weekend in the 2-4inch range (with locally higher amounts) flooding has been a concern. Here are the current Flood Warnings for the Tennessee Valley. Remember: Turn around, don't drown.
A the low slowly tracks east for the work week, more rain is expected. Off and on showers and a few imbedded thunderstorms will continue into Monday. We’ll see some breaks in the rain but it will be a pretty soggy day.
The showers finally taper off by Tuesday as warmer, near average, temperatures return for the midweek.
Our next rain maker looks to arrive by next weekend. I’ll have more information on that system coming up on WAFF48 News at 10pm.
