Iowa climate: What to learn about robust storms anticipated Monday

KCCI EIGHT NEWS AT SIX. WELCOME BACK. WE WANT TO TURN THINGS BACK OVER TO OUR FORECAST. ZANE BEAUTIFUL TODAY, BUT YOU’RE TRACKING A LOT DURING THIS EIGHT DAY STRETCH. UNFORTUNATELY, A FEW CHANGES COMING UP, ESPECIALLY THE NEXT COUPLE OF DAYS HERE. KAYLA, AFTER TODAY’S BEAUTIFUL BLUE SKIES, WE’RE GOING TO GET MORE CLOUDS INTO TOMORROW. THERE MIGHT BE A COUPLE OF SPOTTY RAINDROPS TO FOR THE FIRST HALF OF YOUR SUNDAY. THE MAIN STORY STILL IS THE RISK OF SEVERE WEATHER AS WE HEAD TOWARDS THIS COMING MONDAY. THAT’S NOT LOCKED IN ENTIRELY, THOUGH. WE DO KNOW IT’S FOR SURE GOING TO BE A LITTLE BIT WINDIER, AND THAT SHOULD STAY WARM AND WINDY. ACTUALLY. OTHERWISE ON MONDAY. BUT JUST IN CASE YOU DIDN’T NOTICE, YEAH, THERE IS GOING TO BE SOME WIND. SPEAKING OF THE STORM POSSIBILITIES THOUGH, I GOT TO DO A KIND OF FUN VISIT THIS PAST WEEK OUT AT SCHULER AND WALNUT HILLS ELEMENTARIES IN WAUKEE. THE FIFTH GRADE BANDS THERE, THEY’RE ACTUALLY PLAYING A STORM. A SONG THAT’S CALLED STORM CHASING. SO I GOT TO GO TALK TO THOSE KIDS ABOUT STORM CHASING, WHAT IT’S LIKE AND HOW IT RELATES TO THEIR MUSIC AND ALL THAT FUN STUFF. EARLIER ON THIS PAST WEEK. SO THAT WAS KIND OF A COOL THING TO DO. YOU CAN’T SEE IN THAT PICTURE OF THE WALNUT HILLS KIDS, THE KCCI STORM CHASER IS RIGHT BEHIND. IT MIGHT ACTUALLY HAVE SOME STORMS TO CHASE. UNFORTUNATELY, HERE THIS COMING WEEK, HERE’S THE LATEST RISK OF SEVERE WEATHER FOR MONDAY. SO THIS GOT UPDATED EARLIER THIS MORNING BY THE STORM PREDICTION CENTER. HIGHEST ONE IS LEVEL FOUR. RISK THAT RED ZONE THAT COVERS BASICALLY MUCH OF CENTRAL AND ESPECIALLY NORTHEASTERN IOWA. BUT THERE’S EVEN A LEVEL THREE RISK, WHICH IS PRETTY HIGH IN ITSELF ACROSS VIRTUALLY THE ENTIRE STATE. NOW, IT’S STILL A PRETTY BROAD WINDOW FOR REASONS WE’LL TALK ABOUT FROM ABOUT MIDDAY INTO THE EVENING HOURS MONDAY. SO YOU COULD BASICALLY SAY MONDAY LUNCHTIME TO MAYBE TEN, 11:00 AT NIGHT. WE STILL HAVEN’T BEEN ABLE TO ZERO IN A LITTLE BIT MORE THAN THAT. AND STILL ALL THREATS ARE ON THE TABLE. SO ANYTHING FROM LARGE HAIL TO WIND TO TORNADOES ARE ALL POSSIBLE. LET’S LOOK AT THE CURRENT DATA FOR MONDAY. WE’LL START MONDAY MORNING AROUND SUNUP. SOME CLOUDS. THERE MIGHT ACTUALLY BE SOME OVERNIGHT THUNDERSTORMS FROM SUNDAY NIGHT INTO MONDAY. AND THEN WATCH AS WE GO THROUGH THE MORNING AND INTO THE AFTERNOON. WE GET MORE SUNSHINE. OUR TEMPERATURES REALLY SHOOT UP MONDAY ABOVE 80 DEGREES LOOKS PRETTY POSSIBLE IN A LOT OF SPOTS. SO WE’LL HAVE THE HEAT. WE’LL HAVE SOME HUMIDITY TOO. YOU’RE GOING TO NOTICE A LITTLE BIT OF MUGGY AIR ON MONDAY, AND YOU’LL NOTICE A BREEZE. GUSTS OUT OF THE SOUTH TO MAYBE A LITTLE BIT SOUTHWEST OF AROUND 35MPH OR SO. SO WE HAVE MOST OF THE INGREDIENTS FOR SEVERE WEATHER ON MONDAY, AND YET YOU DON’T SEE ANY STORMS POPPING UP HERE BY 4:00 IN THE AFTERNOON. WE DON’T HAVE AN OBVIOUS TRIGGER JUST YET. YOU SEE, THERE’S A BOUNDARY THAT’S CALLED A DRY LINE. THAT YELLOW FRONT WAY OUT TO OUR WEST, THAT’S STILL WAY OUT TO OUR WEST MONDAY AFTERNOON. THERE’S LOW PRESSURE, BUT THAT’S WAY OFF TO OUR NORTH, UP INTO MINNESOTA. THAT’S ONE QUESTION MARK. WE DON’T KNOW JUST YET. EITHER WAY, WE’LL HAVE TO FIGURE OUT EXACTLY IF STORMS CAN FORM WITHOUT A BOUNDARY OR SOMETHING LIKE THAT, BECAUSE THAT BOUNDARY WON’T BE HERE UNTIL LATER ON MONDAY NIGHT. AND THEN ONCE THAT’S GONE, THAT’S WHEN WE DON’T HAVE ANY KIND OF RISK. SO, YOU KNOW, 11:00 MIDNIGHT, SOMETHING LIKE THAT. BY TUESDAY. WE’RE STARTING TO COOL BACK DOWN. SO RE TRACK FROM MONDAY TO TOMORROW. IN THE MEANTIME, WE’RE GOING TO HAVE MAYBE A SPOTTY RAIN SHOWER, BUT DEFINITELY MORE CLOUDS AND A BREEZE FOR YOUR SUNDAY TOMORROW. STILL SOME 60S, JUST NOT AS MUCH SUNSHINE AS WE SAW TODAY. A BIT OF A BREEZE TOMORROW COMING OUT OF THE SOUTH AND THE EAST. THE REST OF TONIGHT WE’RE JUST GOING TO SEE MORE OF THESE CLOUDS START TO THICKEN UP ACROSS IOWA THROUGH TOMORROW MORNING AND THEN INTO TOMORROW AFTERNOON. SO A LITTLE BIT GRAYER, ESPECIALLY CENTRAL AND WESTERN IOWA, EASTERN IOWA, YOU MIGHT SEE MAYBE A LITTLE BIT OF SOME SUN STILL TOMORROW, A SMALL CHANCE OF A SHOWER OR TWO. SO 66 TOMORROW SHOOTING UP INTO THE 80S ON MONDAY. WE STILL GOT TO PIN DOWN SOME DETAILS ON THAT SEVERE WEATHER RISK. MONDAY COULD BE PRETTY HIGH END, BUT IT’S GOING TO TAKE EVERYTHING TO GO JUST RIGHT. I KNOW THAT’S NOT THE ANSWER EVERYBODY WANTS, BUT THAT’S KIND OF WHERE THINGS STAND RIGHT NOW. SO STAY TUNED ON THAT DRIER. THEN TUESDAY BACK TO 60
