First Alert Weather: Severe storms and possible isolated tornadoes over the weekend
Apr 14 2018 by Cristina Jennings
Conditions remain dry early on Saturday. Confidence is increasing for a risk for damaging winds. The tornado threat is low at this time. A strong upper level low will move overhead during the afternoon and evening triggering thunderstorms that will eventually become severe during the afternoon and evening. A Flash Flood Watch is in effect for Limestone, Morgan, Lauderdale, Colbert, and Franklin counties in Alabama from 7 AM Saturday to 1 AM Sunday.
There is a likely chance of scattered thunderstorms in the forecast for Friday. Cooler air moves in with highs only in the 60s. As it does, it will send a cold front first through the ArkLaTex and then into our area late Saturday morning and into Sunday morning.
Temperatures do cool down slightly with highs in the middle 70s on Friday. These storms will be a high wind/large hail threat, but an isolated weak tornado can't be ruled out overnight. Early rain with some snow mixed in will move east to the border this morning and we'll be mainly dry past 12pm today other than light showers lingering along the eastern border.
The main threat to our area still looks to be damaging winds up to 65 miles per hour but there is a chance we could see a few isolated tornadoes, especially west of the Mississippi River. Additional strong to severe storms may redevelop by midday and continue throughout the afternoon.
Spring-time storm systems are notoriously hard to predict and some changes to the forecast are likely including a possible increase or decrease in the risk of severe storms. Eventually, this line of storms will get an eastward nudge; that may take until later on in the afternoon and even into our Saturday night. Expect snow to taper through the mid-morning and temperatures to slowly warm into the low 40s as our skies clear.
