PRELIMINARY: 7 TORNADOES MONDAY

Monday's long-lived, tornado producing storm's damage is still being assessed by NWS Indianapolis and North Webster. Preliminary reports of as many as 7 tornadoes have been determined but the investigation is on going and that number could likely climb. The parent storm held together and tracked over 100 miles form Hendricks county to Allen county and then dissipated just north of Ft. Wayne.

Here is the latest from NWS Indianapolis as of 9:45 PM Tuesday.

EF0 Tornado near Clayton in Hendricks County

EF1 Tornado 2.5 miles northwest of Avon in Hendricks County

EF1 Tornado one half mile east of Pittsboro in Hendricks County

EF0 Tornado 4 miles west of Battleground in Tippecanoe County

EF2 Tornado 2.5 miles south and southeast of Whitestown in Boone County

EF1 Tornado 2.4 miles northeast of Sheridan in Hamilton county

EFO Tornado 6 miles northeast of Greentown in Howard county

The likelihood of additional tornadoes will be high, given the storm's history. More on this in the days ahead.

How rare are August tornadoes in Indiana? Surprisingly rare actually. We average just under 2 per year and of the warm weather month's the least (March through August). The tornadoes are the first August tornadoes in Indiana since 2012.

RAIN CHANCES CONTINUE

Rain showers are scattered this evening and a quick downpour is still possible through 12 AM. The flash flood watch that has been up for days has been dropped.  However, each of the next 5 days still offers a rain chance but the coverage will be much lower the rest of the work week. We will add some needed sun and that will allow the temperature to rise.

HUMIDITY TO TAKE A DIVE

The next heavier round of rain appears to arrive with a humidity busting cold front Saturday into Sunday. We are looking for a huge dive in humidity starting next week and the least humid air in nearly 2 weeks! A fall-like feel is possible early morning Monday and Tuesday next week. Stay tuned!
