A severe thundestorm watch has been issued for northern Indiana until 10 PM. This is a PDS severe thunderstorm watch. That stands for particularly dangerous situation. The counties included are:
Benton, Jasper, Newton, Porter, White, Cass, Miami
What does PDS mean? It means that there is a heightened risk of storms producing widespread damage as they roll through. For us, this means we could see winds up to 80 mph as this line of storms moves into the watch area. Also, isolated large hail events up to 1.5″ in diameter are possible along with a tornado or two.
The Storm Prediction Center has now included the northwest portion of our state in a MODERATE RISK of severe weather for tonight. That’s the area in orange in the picture. Our number one threat from this line of storms that will move in after sunset will be damaging winds. We could see a derecho (long lived, damaging wind event) unfold over the Ohio Valley with our state in the path of this event. Winds over 60 mph would be possible along with large hail and even isolated tornadoes. As for the specific timing, that is still coming into focus as the atmosphere recovers from the morning storms and new storms develop out in Iowa.
