The National Weather Service in Chicago (NWS) has issued an excessive heat watch for Northwest Indiana, in effect today through 7 p.m. Saturday, July 20.

A multiple day episode of dangerous heat is expected later this week centered on Friday into the start of the weekend. This heat will expand into the area on Thursday afternoon and persist through Friday and into Saturday.

There is a potential for showers and thunderstorms on Thursday morning which may keep the rest of the day cooler than forecast, but confidence is increasing in dangerous heat arriving by Friday.

In addition, there will be little relief from the heat overnight Thursday and Friday, with the urban heat island core of Chicago most susceptible to night time temperatures which do not cool significantly, limiting the amount of relief that can occur at night.

High temperatures will peak in the 90s each day, with Friday and Saturday potentially in the upper 90s to near 100 degrees. Maximum heat indices: peaking to 102 to 112 each day. Low temperatures will drop only to the upper 70s to near 80 on Thursday and Friday nights.

“The cumulative effects of temperatures and heat index values this high could lead to heat related illnesses with prolonged exposure,” NWS said. “Those without air conditioning, elderly, small children, and pets are especially susceptible. Plan ahead. Have a cool place to shelter from the heat. Avoid outdoor activity, especially strenuous ones, during the peak heating times of the day. Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors.”
