Monday: hot temps with chance of rain this evening

(WJBK) - A heat advisory is in effect for all of southern Michigan Monday, with the heat index reaching near 100 degrees this afternoon. 

Temperatures will quickly climb to around 90 degree by noon today, with highs this afternoon in the lower to mid 90s. The heat index values will reach 95 to 100 degrees this afternoon. The heat index is taken by combining the temperature and the dew point, giving you how the air really feels.

There is a slight chance for some scattered showers this afternoon, though it wouldn't cover the whole metro area. Chances are greater, though, that by evening our chance for rain increases. Chances for scattered rain linger overnight as well. 

Any of these rainstorms that do form could bring heavy rainfall, due to all the moisture and humidity already in the air. Keep an eye on the radar with your FOX 2 Weather app.

The combination of hot temperatures and high humidity will combine to create a situation in which heat illnesses are possible. Drink plenty of fluids; stay in an air-conditioned room; stay out of the sun and check up on relatives and neighbors. Take extra precautions if you work or spend time outside. 

Here's a list of cooling centers in the metro area here for those who may need relief from the heat. 

The heat advisory expires at 6 p.m. Fortunately temps will quickly drop this evening as a cold front comes through the area. Lows are expected in the mid to upper 60s overnight. It will stay cooler then for the rest of the week, though "cooler" is a relative term.

High temps will still be in the upper 70s to low 80s this week.
