Iowa weather: Scattered severe storms follow heat for much of the state

Iowa weather: Scattered severe storms follow heat for much of the state
GOOD NEWS. TODD MAGEL, THANK YOU VERY MUCH. AND ALL THIS RAIN IS KIND OF TAKING THE NEED TO USE YOUR IRRIGATION SYSTEM OUT. SO FOR CENTRAL IOWA WATERWORKS CUSTOMERS, THAT’S NOT SO BAD. THAT’S A LOT OF HELP RIGHT THERE. THAT IS A LOT OF HELP. AND WE COULD SEE SIGNIFICANT RAIN IN SPOTS TWO THREE INCHES AS WE HEAD INTO TOMORROW MORNING. SO GOOD TO SEE THAT. YOU CAN SEE RIGHT NOW OVER CENTRAL PORTIONS OF THE STATE METRO UPWARDS TOWARDS COLFAX. WE’RE CONTINUING TO SEE THOSE SHOWERS AND THOSE THUNDERSTORMS THAT HAVE BEEN PUSHING THEIR WAY ON THROUGH CARLISLE, DOWN THROUGH HARTFORD, DOWN THROUGH INDIANOLA. AND YOU GO UP A LITTLE BIT FURTHER IN THAT WHOLE AXIS OF SHOWERS AND THUNDERSTORMS CONTINUES CLEAR ALL THE WAY INTO WISCONSIN. SO WE DID HAVE THAT ONE WIND GUST REPORT FROM THE DES MOINES INTERNATIONAL AIRPORT AT 62MPH. OTHERWISE, HAVEN’T HAD MUCH. AS FAR AS REPORTS GO WITH THIS SYSTEM JUST YET. YOU CAN SEE AS THIS GETS TO THE BACKSIDE OF IT, IT BECOMES A LITTLE BIT MORE RAGGED, BUT A STRONGER CELL EAST OF CRESTON RIGHT NOW AND A LITTLE BIT FURTHER TO THE SOUTHWEST, IS WHERE THE STRONGEST STORMS SIT FROM CLARINDA EASTWARD TOWARDS AROUND BEDFORD, LIKELY VERY ACTIVE LIGHTNING WISE. COULD SEE SOME WIND GUSTS, PERHAPS UPWARDS OF 50MPH IN THOSE CELLS, AND THAT CONTINUES ALL THE WAY DOWN THROUGH NEBRASKA CITY AND DOWN INTO SOUTHEASTERN PORTIONS OF NEBRASKA. SO WE LOOK AT YOUR HOUR BY HOUR, AND AS WE HEAD THROUGHOUT THE EVENING HERE, WE’RE GOING TO CONTINUE TO SEE THESE STORMS WORK THEIR WAY TO THE EAST, EVENTUALLY PUSHING TOWARDS OTTUMWA BY AROUND 10:00. AND THEY’RE GOING TO BE WORKING THEIR WAY OUT OF THE STATE. THAT INITIAL LINE FADES, AND WE CONTINUE TO SEE MORE SHOWERS AND THUNDERSTORMS WORK THEIR WAY IN FROM THE SOUTHWEST. SO BY TOMORROW MORNING, YOU’RE LIKELY GOING TO CONTINUE TO SEE THOSE SHOWERS AND THUNDERSTORMS, ESPECIALLY FOR EASTERN PORTIONS OF THE STATE. WE MAY CATCH A LITTLE BIT OF A BREAK THROUGH CENTRAL IOWA THROUGHOUT, BUT THROUGH ABOUT THE NOON HOUR BEFORE MORE CHANCES FOR SHOWERS AND THUNDERSTORMS START TO FIRE UP, ESPECIALLY FOR SOUTHERN PORTIONS OF THE STATE. SO TOMORROW LIKELY NOT AS STORMY AND NOT AS RAINY AS TODAY, BUT WE’LL STILL HAVE A CHANCE AND COULD EVEN SEE AN ISOLATED, STRONG STORM. OUR SEVERE WEATHER OUTLOOK FOR TOMORROW IS A LEVEL ONE RISK ON A SCALE THAT GOES ALL THE WAY UP TO FIVE. SO REMEMBER TODAY WE WERE AT THAT LEVEL TWO RISK AND TOMORROW’S THREAT NOT QUITE AS LARGE, BUT STILL COULD SEE AN ISOLATED, STRONGER STORM. LIKELY CONTINUING TO SEE A BIT OF RAIN AS WE HEAD INTO THE MIDDLE OF THE WEEK. AND A LEVEL ONE RISK THERE AS WELL. OF COURSE, AS WE GET A LITTLE BIT CLOSER, THESE THINGS CAN CHANGE SOME, BUT JUST PLAN ON A SOGGY STRETCH INTO THE END OF THE WEEK. THAT RAIN TRACKER. KEEP IN MIND THIS IS ADDITIONAL RAIN COULD SEE 1 TO 2IN JUST THROUGH 10:30 P.M. ON TUESDAY. WE’VE GOT RAIN CHANCES CLEAR THROUGH THE END OF THE WEEK, SO THIS IS EVENTUALLY GOING TO START TO ADD UP. COULD LEAD TO SOME LOCALIZED PONDING IN SPOTS. AS WE START TO WORK OUR WAY TOWARDS AROUND WEDNESDAY OR THURSDAY. OMINOUS CLOUDS THOUGH IN THE METRO RIGHT NOW, THOUGH, WE’RE NOT SEEING AS MUCH RAIN IN THE METRO. IT’S JUST KIND OF DARK OUT THERE. AREAS LIKE ALGONA GOT THOSE DARK CLOUDS AS WELL, SHOWERS WORKING THEIR WAY THROUGH MARSHALLTOWN AND EVEN DOWN TOWARDS LAMONI. THAT 12 HOUR FORECAST FOR TOMORROW KIND OF SPLITS THE DAY. GOT THOSE SHOWERS AND THUNDERSTORMS EARLY ON AND THEN GET THAT BREAK A LITTLE BIT THROUGH THE MIDDLE PORTION OF THE DAY BEFORE THEY SURGE BACK IN. GOING TO BE COOLER OUT THERE TOMORROW THOUGH. HIGHS SITTING AT 82. AND WE’LL KEEP CHANCES ALIVE FOR SOGGY WEATHER WEDNESDAY AND THURSDAY AS TEMPERATURES CLIMB BACK TO 90 DEGREES AND WE HANG OUT IN THE MID 80S TO LOW 90S THROUGH TUESDAY. BUT FRIDAY AND SATURDAY LOOKING GOOD AS WE HAVE GOT MOSTL
