Severe storms with high winds, mid-90s temperatures on tap into the weekend

Days of warm, sunny weather will soon end, ushering in a period of rain, wind and thunderstorms in Central Indiana on Friday and into the weekend.
After a hot and humid Friday morning — heat indices are expected to reach 100-105 degrees, National Weather Service meteorologist Alexander McGinnis said — comes the threat of severe storms.
The NWS has issued a severe weather outlook warning Hoosiers from Kokomo to Bloomington of an enhanced threat of severe storms, likely to bring high winds, heavy rain, hail and a chance of tornadoes between 3-10 p.m. Friday.
Some areas could see 1-2 inches of rain, which could lead to flooding.

NWS meteorologist Mike Ryan told IndyStar on Thursday the best chance for severe weather comes Friday afternoon and evening.
The change in weather is due in large part to a ridge of high pressure over the southern Rockies and the southwestern United States, according to the NWS. Atmospheric disturbances in the area are riding up along the ridge, creating clusters of thunderstorms along the U.S.-Canadian border to the Northern Plains that “dive down” through the Great Lakes and the Ohio Valley.
That system, combined with the heat — Friday will be humid with temperatures approaching the mid-90s — creates that severe weather in Central Indiana, which includes “damaging winds” that could reach speeds of up to 60 or 70 mph.
“It’s a typical summer pattern — something we see at various times in the summer every year,” Ryan said. “It just may feel a little different this year because we just did not have a lot of severe weather really at all here in Central Indiana so far in 2021.”
That severe weather will calm into the weekend, Ryan said. There will be a chance for scattered showers and thunderstorms with highs in the upper 80s.
