Severe Weather Outbreak Underway



As expected, there has been a significant development of storms in the last few hours. Much of Western Ohio and Indiana are now under a Tornado watch until late this evening. As of right now (3PM), the warm front from a 1000mb surface low in north/central IN is located across the Route 6 corridor. As a result, a strong temperature gradient exists, with Toledo in the mid 50s with a light northerly breeze, while Findlay is in the middle sixties with a strong southely breeze. Although cloud cover has kept intability down, severe storms have sufficient fuel with a 90kt wind at 500mb, this is an incredible situation. Even winds at 925mb are at 50kts in NWOH!

As I type, storms in Indiana and extreme NWOH are moving NW at around 50-60mph. This direction has limited easteward movement of these storms in the last hour or two. However, slow movement east is expected as the cold front pushes east later this afternoon. The SPC has kept the 10% hatched tornado probs in areas that have had more instability develop. A large area of 50kt 0-1km shear will be plenty enough to aid for potentially strong tornadoes today.

This is a serious situation. If you are in the path of these storms, take cover immediately. The potential for tornadoes, potentially strong, exists. The greatest potential for tornadoes is a triangle from Findlay, OH to Colubmus, to Indianapolis, IN.
