Really for the first time this summer we will see some extreme heat come over the area. The National Weather Service in St. Louis has issued a Heat Advisory from noon today until 8 pm tonight. We are looking at a high temperature in the low 90s today with heat index readings around 103 for Monday afternoon into Monday night. More than likely this won’t be the last Heat Advisory of the week, with temps in the lower 90s and heat index readings probably getting above 100 a few days this week. The chance of rain is still with us, however, with showers and thunderstorms in the forecast for today, tonight, Tuesday and Tuesday night and then returning on Thursday.
