Potential for Severe Weather on Wednesday

Good Tuesday afternoon, we are looking at a pretty nice day across Indiana and Ohio with lots of sunshine and temperatures generally in the 70s, with cooler 50s and 60s near the lake.  Slide1

The purpose of this blog however is to outline the severe threat and possible timing of showers and thunderstorms.  There could be three separate lines of thunderstorms, but the last two lines will likely be the line that could go severe.  First, let’s discuss the areas that will be under the slight and marginal risks of severe storms.  The slight risk of severe storms will be along and west of a Lagrange-Wabash-Greentown-Tipton-Westfield-Speedway-Martinsville line.  Slide9

Now to the timing, on Wednesday morning through early Wednesday afternoon, a line of non-severe, but potentially strong showers and thunderstorms will move east across Indiana, and will move into western Ohio in a much weaker state.  The atmosphere will likely be able to recover from the morning storms and several new areas/lines of showers and thunderstorms will begin to develop during the early evening hours.  The first line looks to develop in western Illinois, with the other area looks to develop in eastern Illinois.  These lines/areas of storms will move east or southeast into Indiana between 6 and 8 pm and eventually congeal into a solid squall line.  The leading squall line will move into northwest Ohio between 10 and 11 pm and as it moves into Ohio, it will run into a more stable environment and will gradually weaken.  The second line looks to mainly affect northern sections and weaken closer to the midnight hour.  You can see the possible evolution of thunderstorms below.

Finally, the risks, the main threat right now appears to be damaging winds, but large hail, and isolated tornadoes will also be possible.   The best time for severe storms will be between 6 pm and 1 am for Indiana and far western Ohio.  We will have additional updates on the Equinox Weather Facebook page through the day on Wednesday and tomorrow will likely be proclaimed as a “Weather Alert Day”.  Slide12
