00:00 widespread heat today across the plains and all the way down into the central

00:04 Gulf Coast states. But the core of the heat relative to normal is in the

00:08 north-central United States today. Look at all these temperatures up over 100

00:12 degrees or close to it from Chicago Indianapolis all the way down in the

00:16 word Kansas City. Here comes the relief a front coming we'll talk about that

00:20 more in a second but this temperatures today it's a hot day and this is the

00:24 hottest day Chicago has seen in almost 11 years. When is the last time we had a

00:29 high temperature of at least 100 degrees in Chicago? I was a little surprised when

00:34 I looked at this. It's been 11 years the last time we were 103 or over 100

00:40 degrees was July 6 2012 so it's been over 11 years since we've been this hot

00:45 so this is not only the hottest day of the year yesterday was the hottest day

00:49 of the year when it was 98 degrees in Chicago that broke the record of 97 set

00:53 in 1947 but not only is this the hottest day of the year it's the hottest day

00:57 that we've had in 11 years in Chicago. It is hot. Records are going to be

01:02 challenging broken across Iowa, Missouri, Indiana, Ohio and Kentucky today lots of

01:08 records challenged today as temperatures continue to rise and then you look at

01:12 your AccuWeather real field temperatures and we're zoning in on that red area

01:15 from the boot hill of Missouri toward Memphis all the way toward Shreveport

01:19 Louisiana where we're going to see an AccuWeather real field temperature

01:22 between 115 and 120 degrees. The other story with this and you forget about

01:28 this but what is just as crucial in a heatwave is the temperatures at night.

01:34 Certainly it's hot during the day but you know what if you can cool things

01:37 down into the 60s there's some relief for people that do not have air

01:41 conditioning but there's not going to be much relief even in Chicago you're in

01:44 the 70s tonight cooler than what you were last night but that's not going to

01:48 help much. Meanwhile look at st. Louis toward Kansas City along Interstate 7

01:52 temperatures tonight mostly in the 80s so no relief there but there is relief

01:58 coming because there's our upper level high now across eastern Oklahoma. What

02:03 we were talking about this yesterday is this moves to the south our wind flow

02:06 instead of coming in from the west southwest starts coming in from the

02:09 north northwest and that will bring a cold front southward. Watch where this

02:12 upper high is going to go as we continue to move through the period. It moves a

02:16 little farther east as we go through Friday. See here's the dip in the jet

02:19 stream now wind flow coming in from the north our front comes south here comes a

02:24 relief. Then that high kind of meanders around Friday and Saturday and then it

02:29 pushes to the south and east over the weekend and that will allow finally some

02:34 relief into the southern plains in Texas Sunday in the southern plains early next

02:40 week in the Texas. They'll be dancing in the streets in Chicago by the time we

02:45 get into Saturday we're going to be in the 70s what a refreshing air mass. Same

02:48 story in Minneapolis Detroit you're going to cool down Cincinnati you're

02:52 going to cool down even Kansas City you're going to go from a 103 degrees

02:55 on Friday to 85 degrees on Sunday with some thunderstorms. Also all of this dry

03:02 weather boy all of this heat continues to allow this drought to expand across

03:07 all of the central United States that's not good so we're going to continue to

03:12 watch that but the heat will be coming to an end. Stay with us.
