The warm and humid air that moved into central Ohio on Friday and Saturday has set the stage for strong to severe storms to develop later this evening. A strong storm system will blast through late tonight, lasting through early Monday, and severe weather will be possible for all of the 10TV viewing area as a result. After widespread morning rainfall Sunday morning, the focus shifts to the next round of storms that is expected to arrive just after sunset. With the severe storm potential, we are declaring a 10TV Weather Impact Alert Day for the second half of Sunday and into early Monday morning. We're watching closely that first round of rain when it comes to an end. If the rain ends earlier in the day and we see clearing skies, the risk for severe storms later in the day will increase. Some of the strongest storms could produce damaging winds, hail — severe criteria is at least 1" in diameter, or the size of a quarter — the possibility for spin-up tornadoes and a minor risk for flooding. The most likely danger will be strong damaging winds, so make sure your yard and home are prepared. The risk of spin-up tornadoes remains an increased concern, which can happen sometimes with little to no warning. So make sure your phone is fully charged so you have ways to get warnings or have a NOAA weather radio as a backup. Because these storms will fire up after dark, it's even more important to make sure you have a way to stay connected and informed, especially while you are sleeping. The current timeline has storms arriving and developing between 6 to 8 p.m. in our western counties, around 7 to 10 p.m. in the Columbus region and between 8 to 10 p.m. for our eastern counties. Once the main line of severe storms moves through, the threat should significantly diminish and switch over to rain lingering into Monday morning. As these bowing segments push out, the risk for spin-up tornadoes near the edges of the bowing segments will be possible. As for threat timing in Columbus, we think most of the risk will come after sundown. Wind will still be our primary focus, but all types of severe weather will show peak risks at a similar time. Flooding, while possible, will remain a minor factor. The 10 Weather Impact team will continue to monitor this system closely and update the forecast as details become clearer!
