Iowa weather: Heat continues and storms pop up

More 90s are possible as a new week begins.

ADVENTURELAND’S WEBSITE TODAY. IF YOU’RE GOING OUTSIDE, BETTER BE PREPARED FOR IT BECAUSE IT’S GOING TO BE A HOT ONE. AND REALLY, WHEN WE TALK ABOUT HEAT, WHEN IT COMES TO THIS POINT, YOU JUST GOT TO PREPARE FOR IT. YEAH, EXACTLY. WE’RE TALKING ABOUT ALL THESE FALL ACTIVITIES, BUT IT’S FEELING MORE LIKE JULY 4TH OUT THERE BY THIS AFTERNOON. IT IS GOING TO BE A HOT ONE. SO IF YOU DO HAVE OUTDOOR PLANS, MAKE SURE YOU’RE PLANNING TO HAVE EXTRA WATER ON HAND BECAUSE YOU DO WANT TO STAY HYDRATED OUT THERE. DON’T WANT ANYBODY SUFFERING FROM HEAT EXHAUSTION OR HEAT STROKE HERE. AS WE HEAD INTO THE AFTERNOON HOURS. THANKFULLY, THE HUMIDITY IS NOT TOO BAD, SO THAT WILL HELP OUT A LITTLE BIT. BUT WE ARE TALKING ABOUT NEAR RECORD HEAT HERE BY THIS AFTERNOON. HIGHS IN THE MID 90S, ABOUT 94 TO 96 DEGREES HERE ACROSS CENTRAL IOWA. AND OUR RECORD HERE IN DES MOINES IS 96. SO IT’S NOT OUT OF THE QUESTION THAT WE COULD TIE THE RECORD HERE THIS AFTERNOON. NOW THE NEXT FEW DAYS WON’T BE QUITE AS HOT AS TODAY, BUT WE’RE STILL TALKING 90S FOR SUNDAY, MONDAY AND TUESDAY. BUT AGAIN, THANKFULLY THE HUMIDITY IS NOT TOO BAD. SO OUR HEAT INDEX TODAY IS ONLY ABOUT TWO DEGREES ABOVE THE ACTUAL TEMPERATURE, SO IT FEELS LIKE 98, WHILE THE THERMOMETER SAYS 96. AND THEN THE NEXT COUPLE OF DAYS HEAT INDEX READINGS IN THE LOW TO MID 90S. SO NOT AS BAD AS WHAT WE HAD IN AUGUST, BUT STILL VERY MUCH ON THE HOT SIDE. IT’S NOT UNTIL THE MIDDLE OF NEXT WEEK THAT WE SEE A COLD FRONT AND STORM CHANCES ENTER THE FORECAST, WHICH WILL HOPEFULLY BRING TEMPERATURES DOWN JUST A LITTLE BIT. WE’LL SHOW YOU JUST HOW HOT TODAY COULD BE. SO FAR, OUR HOTTEST TEMPERATURE THIS YEAR WAS 97. THAT WAS BACK IN JUNE. AND OF COURSE OUR FORECAST TODAY 96 DEGREES. SO WE’RE WITHIN A DEGREE OF THE HOTTEST WEATHER AT LEAST ON THE THERMOMETER THAT WE’VE SEEN. NOW BACK IN AUGUST, OUR HEAT INDEX WAS WELL INTO THE TRIPLE DIGITS. SO IT’S NOT GOING TO FEEL QUITE THAT HOT. THANKFULLY, YESTERDAY WE DID MANAGE SOME CLOUD COVER, A COUPLE OF SHOWERS, A LITTLE MORE SHOWER ACTIVITY THAN EXPECTED, AND THAT HELPED TO KEEP OUR TEMPERATURES DOWN ACROSS CENTRAL IOWA. OUR HIGH WAS 87, BUT NOTICE CRESTON. THAT’S KIND OF WHAT WE WERE EXPECTING. WITH A LITTLE MORE SUNSHINE. IT GOT UP TO 97 YESTERDAY IN CRESTON, SO WE DON’T HAVE THOSE CLOUDS AND SHOWERS OUT THERE TODAY. THAT’S WHY I THINK IT IS GOING TO BE ON THE HOT SIDE. THERE’S BEEN A COUPLE LITTLE PATCHES OF CLOUDS HERE AND THERE, BUT NO WIDESPREAD CLOUD COVER OR SHOWER ACTIVITY IN EASTERN NEBRASKA TODAY TO SAVE US FROM THE HEAT. THERE’S THAT SUNSHINE RIGHT NOW HERE IN DES MOINES. TEMPERATURES 69 DEGREES. THAT WAS AT THE TOP OF THE HOUR. WE’LL SEE THAT UPDATE INTO THE MID 70S HERE SHORTLY. ALREADY SEEING MID 70S ACROSS THE STATE 73 IN GRINNELL, 73 IN CARROLL, 73 IN SHERATON KNOXVILLE. YOU’RE UP TO 75 NOW. SO IT IS GOING TO HEAT UP QUICKLY WITH ALL OF THAT SUNSHINE. WE’RE TALKING AGAIN. HIGHS IN THE 90S A FEW CLOUDS ROLLING IN DURING THE AFTERNOON. BUT THE FORECAST IS DRY TODAY. TOMORROW STILL EXPECTING HOT CONDITIONS. HIGHS AROUND 92, BUT THERE COULD BE A COUPLE OF SPOTTY SHOWERS THERE IN WESTERN PARTS OF THE STATE. THOSE COULD TRY TO TRACK EAST INTO CENTRAL IOWA OVERNIGHT INTO MONDAY, BUT THOSE RAIN CHANCES ARE REALLY, REALLY SPOTTY. AND IT LOOKS LIKE MONDAY IS GOING TO BE MAINLY DRY AS WELL, WITH A HIGH AROUND 91 DEGREES. WE HOLD ON TO THE 90S ONE MORE DAY ON TUESDAY AND THEN A COLD FRONT ENTERS THE PICTURE. THAT HELPS TO BRING OUR TEMPERATURES BACK INTO THE 80S ON WEDNESDAY, AND SHOULD HAVE SOME SHOWERS AND STORMS IN THE AREA THROUGH THE MIDDLE PART OF THE WEEK, D

The heat that delivered record temperatures to central Iowa today will still be around into the coming week.After cooling to about 70° tonight, we'll heat back up to low 90s tomorrow afternoon. That's not quite as warm as today, mainly due to more high-level clouds spreading over the state.Interactive Radar | Weather Alerts | SkycamsWe'll also see isolated showers and storms begin to pop up during the afternoon hours.More rain is possible into Sunday night as well, thanks to a strengthening low-pressure trough swinging by us over the Great Plains.Skies should clear into Monday, bringing more sunshine and high temps around 90° both Monday and Tuesday.Tuesday night into Wednesday, another system coming from the Plains drives a front into Iowa. Rain is possible again from this point into next Thursday.The heat will finally give way to 70s during the second half of next as well, bringing Iowa back to more typical September weather just in time for the Fall Equinox.
