Iowa weather: Clouds increase ahead of severe risk next week

Iowa weather: Clouds increase ahead of severe risk next week

Tornadoes, wind, and hail look possible.

THE DELICIOUS DUTCH LETTERS. THE TULIP TIME FESTIVAL STARTS THURSDAY, MAY 1ST AND GOES THROUGH SATURDAY THE THIRD. AND IT IS MY FAVORITE PART OF SPRING ZANE. IT’S ALWAYS SO BEAUTIFUL. EVERYTHING IS BLOOMING, INCLUDING WHAT’S RIGHT THERE BEHIND YOU, RIGHT? YEAH, WE’VE GOT THE TULIPS OVER IN PELLA. IF YOU GO A LITTLE BIT DEEPER INTO SOUTHERN IOWA, RED HORSE STATE PARK IN LUCAS COUNTY, THAT’S JUST OUTSIDE OF CHARITON. ALSO A BEAUTIFUL PLACE TO GO THIS TIME OF YEAR BECAUSE THEY HAVE ALL THOSE REDBUD TREES AROUND THE LAKE. IT’S ABSOLUTELY GORGEOUS HERE FOR THE, YOU KNOW, SHORT TIME THAT THEY ARE BLOOMING. EVEN YESTERDAY WHEN IT WAS SUPER GRAY, TODAY WOULD HAVE BEEN A SPECTACULAR DAY TO GO OUTSIDE. WHEREVER YOU WERE AT FOR ANY KIND OF SPRINGTIME OUTDOOR ACTIVITIES. NOW, EARLY NEXT WEEK, PERHAPS LOOKING A LITTLE BIT LESS SPECTACULAR. SEVERE WEATHER RISK IS STILL LOOKING PRETTY LIKELY HERE AS WE HEAD INTO MONDAY. THE LATEST OUTLOOK FROM EARLIER TODAY FROM THE STORM PREDICTION CENTER LOOKS LIKE THIS. THE HIGHEST RISK LEVEL IS THIS LEVEL FOUR THAT ENCOMPASSES MUCH OF NORTH, CENTRAL AND NORTHEASTERN IOWA IN PARTICULAR. EVEN IF YOU’RE NOT IN A LEVEL FOUR RISK, THOUGH, VIRTUALLY THE ENTIRE STATE. THAT ORANGE COLOR, LEVEL THREE, THAT’S STILL PRETTY SIGNIFICANT IN ITSELF. STILL PRETTY WIDE WINDOW OF TIME WE’RE LOOKING AT FOR THE TIME BEING, EARLY AFTERNOON ALL THE WAY THROUGH THE EVENING HOURS. THERE’S STILL SOME DETAILS TO WORK OUT THERE WE’LL TALK ABOUT. AND ALL THREATS CURRENTLY ARE ON THE TABLE TOO. NOW, THIS OUTLOOK IS PROBABLY GOING TO GET TRIMMED A LITTLE BIT AND ADJUSTED HERE LATE TONIGHT. SO TOMORROW MORNING WE WILL HAVE THE LATEST. LOOK AT THAT. THE GENERAL IDEA LOOKS SORT OF LIKE THIS THROUGH THE MORNING TO MIDDAY HOURS. AND MONDAY WE’RE GOING TO ADD A LOT OF MOISTURE TO THE AIR FROM THE SOUTH IS GOING TO BE PROBABLY OUR MOST HUMID DAY SO FAR THIS SPRING. COMING UP ON MONDAY, IT GETS PRETTY WARM AS WELL, AFTERNOON TO EVENING. THEN WE GET INTO THAT KIND OF BIGGER WINDOW. WE’RE GOING TO TRY TO FORM SOME STORMS, BUT THEY MIGHT HAVE SOME ISSUES FOR REASONS WE’LL TALK ABOUT. SO WE MIGHT NOT HAVE WIDESPREAD STORM ACTIVITY. AND THEN THE LAST AS LONG AS INTO MAYBE ABOUT 11:00 MIDNIGHT OR SO BEFORE THEY MOVE OFF TO THE EAST LATE TONIGHT. WE’VE JUST GOT MOSTLY CLEAR SKIES FOR THE TIME BEING. A FEW OF THOSE SHOWERS YOU MENTIONED EARLIER, NORTHWEST IOWA, THERE’S ACTUALLY SOME LOWER LEVEL CLOUDS OUT TOWARDS NEBRASKA. THOSE ARE GOING TO SPREAD ON IN HERE LATE TONIGHT AND INTO TOMORROW MORNING. SO WE’LL STOP THE CLOCK AT LUNCHTIME TOMORROW. MAYBE A SPOTTY SPRINKLE OR A BRIEF SHOWER. SPECKLES THE MAP. THE FIRST HALF OF YOUR SUNDAY. OTHERWISE YOU’LL JUST NOTICE MORE OVERCAST SORT OF SKIES BACK INTO THE AREA TOMORROW NIGHT AND INTO MONDAY. BIG WARM FRONT MOVES THROUGH THAT ALLOWS THAT BIG INFLUX OF MOISTURE, MUGGY AIR TEMPERATURES, VERY WARM AS WELL. AND THEN IF YOU LOOK AT THE OVERALL WEATHER SETUP, WE’VE GOT A LOW PRESSURE CENTER UP TOWARDS PARTS OF MINNESOTA. WE’VE GOT A FEW BOUNDARIES, BUT ONE COUPLE OF THEM ARE WAY TO OUR WEST. THAT YELLOW ONE’S CALLED A DRY LINE BASICALLY SEPARATES THE WARM, MUGGY AIR FROM THE VERY DRY AIR. WE DON’T REALLY HAVE ANY OBVIOUS TRIGGERS HERE IN IOWA. AND SO YOU NOTICE BY THE EARLY EVENING RIGHT NOW, THE MODELING DOESN’T INDICATE A LOT OF WIDESPREAD STORMS. THAT’S GOING TO BE ONE THING WE’RE LOOKING AT. FOR STARTERS, WE’RE GOING TO HAVE A THICK KIND OF SMOTHERING LAYER OF WARM AIR ALOFT THAT COULD SUPPRESS STORM DEVELOPMENT. AND SO WE’RE GOING TO NEED SOMETHING TO BREAK THROUGH THAT. ONE OF THOSE POSSIBILITIES MIGHT BE SOME HEAT WE’LL TALK ABOUT. BUT FOR NOW THERE ARE QUESTIONS ABOUT MONDAY HAS POTENTIAL TO BE A SIGNIFICANT SEVERE WEATHER DAY. IT ALSO HAS THE POTENTIAL TO NOT HAVE VERY MANY STORMS AT ALL. THAT’S STILL A QUESTION THAT NEEDS TO BE WORKED OUT. I KNOW THAT’S NOT NECESSARILY THE CLEAR SORT OF FORECAST THAT YOU ALWAYS WANT TO HEAR, BUT THAT’S THE WAY IT LOOKS RIGHT NOW. ONE WAY TO BREAK THROUGH SOME OF THAT HOT AIR ALOFT IS GOING TO BE HOT AIR AT THE GROUND LEVEL. TO ALLOW THAT AIR TO ROCKET UPWARDS. WE’RE LOOKING AT TEMPERATURES ABOVE 80 DEGREES ON MONDAY AND SOME STRONG WINDS TO BOOT AS WELL. OUT OF THE SOUTH AND WEST, 35 TO 40MPH, ALTHOUGH SOUTHWESTERLY WINDS AT THE GROUND LEVEL IS USUALLY NOT VERY FAVORABLE FOR TORNADIC DEVELOPMENT. SO THAT’S ONE GOOD PIECE OF NEWS THERE. IT’S BETTER TO SEE SOUTHWEST WINDS THAN TO SEE MAYBE SOUTHEASTERLY WINDS. SO A FEW QUESTION MARKS REMAIN. BUT FOR NOW, MONDAY STILL LOOKS LIKE POTENTIALLY COULD BE A PROBLEM. BUT THERE ARE SOME ISSUES FOR STORMS TO DEVELOP, WHICH IS GOOD TOMORROW. IN THE MEANTIME, SOME SPOTTY RAIN POSSIBLE IN THE MORNING. JUST SOME CLOUDS. A BREEZE OUT OF THE SOUTHEAST. WE’LL STILL SEE TEMPERATURES IN THE 60S THOUGH. TOMORROW, MONDAY, THEN HOT AND WELL, NOT HOT. WE’LL WARM. WE’LL CALL IT WARM. MAYBE A LITTLE BIT HOT. FEELING PRETTY MUGGY TOO. ONCE THOSE STORMS. ANY OF THEM THAT DO FORM TOWARDS THE SECOND HALF OF MONDAY AND MONDAY NIGHT FORM AND GET OUT OF HERE, WE’LL DROP TO 60 AGAIN TUESDAY. CLEAR SKIES. THERE’S A CHANCE OF A FEW MORE RAINDROPS TO

Iowa weather: Clouds increase ahead of severe risk next week

Tornadoes, wind, and hail look possible.

Following today's spectacular sunshine, Iowa's weather gets busier for the start of the new week.Clouds will increase tonight from the west. A few rain showers will drift into northwest Iowa, but most of the state will remain dry.Tomorrow will be grayer, thanks to low clouds. A few spotty rain showers are possible, mainly during the morning. Temperatures will still climb into the 60s, and winds will gust out of the southeast around 25-30 mph.Monday continues to look like a significant severe weather day IF storms can fire in Iowa.Currently, most of the state has a Level 3 of 5 risk for severe storms. A Level 4 risk area covers central into northeast Iowa. That translates into a 45% risk for severe weather.Temperatures will shoot up into the 80s, accompanied by noticeably humid air. Winds will gust from the south around 35 mph. Iowa will have most of the ingredients for severe storms in abundance, except for an obvious trigger to start them.Low pressure will be centered well to our north in Minnesota. A boundary to the west won't arrive until late Monday evening. For storms to form earlier, we'll need to heat up enough to overcome a smothering warm layer of air aloft.For now, there's a chance of scattered storms (mostly non-severe) overnight Sunday into Monday morning. Severe weather is possible anytime from midday Monday until midnight.Whatever happens Monday, Tuesday will be cooler and sunnier.Another chance of rain comes toward Wednesday.
