Severe Weather

We had a line of storms move across the state this evening after a cool and wet day. Heavy rain began falling early this morning across the area and continued off and on through out the day. There were three rounds of rain between 6am and 5pm with showers in between. After 5pm, the clouds began to break up and the sun appeared. Temperatures for the first half of the day remained in the mid 40's, but shot up to the mid 50's once the sun appeared. The high for the day was 58 at 7pm. With the sunshine, a line of storms developed across western Indiana and moved to the northeast. Tornado warnings and severe thunderstorm warnings were being issued west and northwest of Indianapolis while a severe thunderstorm watch was issued for the eastern two-thirds of the state. At 7:30, the line of storms reached our area with severe thunderstorm warnings being issued for Rush county, but none for Franklin. As the storm approached, the western sky turned very dark and flashes of lightning could be seen to the southwest. There was a slight increase in wind, but nothing like the wind that ushered in the arctic air of last week. There also wasn't an excessive amount of lightning with these storms. Heavy rain was the biggest threat. Only 0.19" fell with the passage of the storms, but that did occur in only twenty minutes. The rain total for the day has been 0.87".

The pictures in this post are from the storms as they approached areas to the north and west of Indianapolis.
