Severe Threat For TodayFebruary 20th, 2014 at 11:36 am by Lindsey Monroe under Weather, WTHI Blog
The Storm Prediction Center has expanded the ‘slight risk’ of severe storms area to include the entire Wabash Valley. Damaging winds gusts up 60+ mph and flash flooding are the main concerns. It isn’t out of the question storms embedded in the line could contain rotation leading to brief spin-ups, although straight line winds look to be a bigger issue. Main timing of this is between 4 and 8 p.m. EST.
A line of t-storms develop along the cold front impacting our IL counties first just after 6 p.m. EST/5 p.m. CST. The line will push into our IN counties around 7 p.m. EST. We could see a few isolated thunderstorms popping-up ahead of the main line. These storms have the potential to reach severe limits with damaging wind gusts.
The line of thunderstorms will begin to exit our IL and impact mainly our IN locations around 8 p.m. EST. This is a very typical “squall line” set-up with all the upper-level atmospheric support needed for strong storm development. By 9 p.m. EST, this quick moving line will move into central Indiana and start to exit the Wabash Valley. Severe threat diminishes at this point as well.
Strong winds (45+ mph gusts) continue during the overnight/early Friday morning. Cold air returns & a few snow flurries are possible.
