Tuesday/Early Afternoon

WEATHER CODE: YELLOW ***Scattered showers and thunderstorms possible***

Still don't have the weather stoplight. Im working on transfering it from my desktop to my laptop.

Very "noisy" days are ahead across the Ohio Valley as bouts of showers and thunderstorms will move through the region. Below is the latest severe weather outlook from the Storm Prediction Center. Areas along and west of the Ohio River will have the best threat of any thunderstorms going severe today. A strong CAP across this region may limit the severity and coverage of severe weather, however isolated severe weather is looking pretty likely with LI's from -5 to -11, and steep low- level lapse rates.

SEVERE WEATHER OUTLOOK-Today


Tomorrow I expect a more widespread severe weather event event to unfold, as an MCS or MCS's march west from the Plains into the Ohio Valley/Midwest. (Latest maps and discussion below). After looking at the latest forecast soundings/models, a pretty decent set-up is in place for severe weather, however instability may pose a problem. We will likely have left over clouds and maybe a few showers in the morning through the afternoon. This may limit overall instability as storms move into our region during the evening and nighttime hours. However, pretty decent severe weather parameters are in place to overcome what could only be "marginal" destabilization. All in all, I do expect severe storms to hold their own, as MCS's can track hundreds of miles. Exact timing of these storms is harder to pinpoint, however computer models are leaning more toward a nighttime event. Best threats with these storms as they move through will be large hail (quarter size or potentially larger) and damaging wind gusts in excess of 60 MPH.

A new update from the Storm Prediction Center will be available in about one hour for tomorrow's severe weather event. I'll update then if maps or discussion change, which I expect it to! More later!
