Storms tonight, then more rain Sunday

A few strong wind gusts, spin-up tornadoes, and heavy rain are all possible in Iowa the rest of this weekend.

WE’RE STILL DEALING WITH SOME WIND PRODUCING STORMS HERE THIS EVENING, KAYLA. THEY’RE MAINLY IN WEST CENTRAL IOWA UP INTO NORTHWEST IOWA AT THIS POINT. WEATHER SERVICE IS JUST A MINUTE OR TWO AGO ISSUED THIS NEWER WARNING. BASICALLY, IT’S THE SAME THREAT WHEN PRODUCING THUNDERSTORM OVER IN GREEN COUNTY AT THIS HOUR. JUST REPLACES THE OLD WARNING WHICH WAS GOING TO EXPIRE OR DID AT 1015. NOW, THE NEW ONE RUNS TILL 11:00. SO WE’LL PAUSE THE RADAR PICTURE. YOU CAN SEE THESE STORMS MOVING GENERALLY OFF TO THE EAST AND SORT OF THE SOUTHEASTERLY DIRECTION HERE AS WE GO THROUGH THE 10:00 HOUR. SO ONE BASICALLY WHERE YOU SEE THESE REALLY SMOOTH LITTLE EDGES, THOSE BULGES, THAT’S WHERE THERE’S PROBABLY SOME STRONGER WIND GUSTS HERE MOVING OUT OF CALHOUN COUNTY AND INTO WEBSTER COUNTY. THIS IS STORM NUMBER ONE. THIS ONE IS PROBABLY PRODUCING OR COULD BE PRODUCING A FEW 60 MILE PER HOUR WIND GUSTS AS YOU GO WEST OF FORT DODGE THERE ALONG HIGHWAY 20, JUST COMING ACROSS THE COUNTY LINE EASTWARD TOWARDS CALLENDER THERE EAST FROM FARNHAMVILLE, OVER TOWARDS GALLERY ALONG HIGHWAY ONE, 75. AND EVENTUALLY IT’LL GO FARTHER INTO WEBSTER COUNTY. THAT STORM, NUMBER ONE, A MOVE IN SOUTHEAST ROUGHLY ABOUT 40MPH, 60 MILE PER HOUR WIND GUSTS. THE OTHER STORM IS THIS ONE THAT’S BASICALLY CUT IN GREEN COUNTY IN HALF AT THIS HOUR. JEFFERSON UP SORT OF BETWEEN PEYTON AND CHURDAN AND THEN SOUTHWESTWARD EVENTUALLY TOWARDS HIGHWAY 141. SO THIS IS GOING TO GO FURTHER SOUTHEAST TOWARDS YALE AND JAMAICA AND DAWSON AND PERRY EVENTUALLY TOWARDS AND NOW INTO DALLAS COUNTY. ONCE THAT STORM CONTINUES, SOUTHEAST FOR ABOUT ANOTHER 45 MINUTES. SO IT’S GOING TO TAKE PROBABLY ANOTHER HOUR AND CHANGE BEFORE IT WOULD GET DOWN TOWARDS THE DES MOINES METRO. IF THINGS GO ACCORDING TO PLAN, WON’T BE AS STRONG BY THAT POINT. BUT PLAN ON THAT IF YOU ARE DOWN CLOSE TO THE DES MOINES AREA THAT STORMS COMING YOUR WAY, PROBABLY 11, 1130, THEREABOUTS, WOULD BE THE MAIN TIMING ON THAT. AND YOU CAN SEE BIG PICTURE WISE, THESE STORMS ARE MAINLY UP IN THAT PART OF THE STATE. REST OF US ARE DRY AND QUIET AT THIS HOUR, BUT THEY’LL CONTINUE OUR DIRECTION. THE TWO BIG PLAYERS COMING OUR WAY TONIGHT AND INTO TOMORROW IS THE LOW PRESSURE CENTER THAT’S UP HERE IN SOUTH DAKOTA THAT’S BEEN HELPING SPAWNING MULTIPLE TORNADOES UP IN NORTHWEST IOWA THIS EVENING. AND THEN A COLD FRONT THAT’S GOING TO COME OUR WAY INTO TOMORROW AS WELL. THOSE ARE OUR TWO MAIN DRIVERS. WE’LL SHOW YOU WHY HERE HOUR BY HOUR. TONIGHT, THOSE STORMS CONTINUE SOUTHEAST. SO 11, 1130, SOMETHING LIKE THAT HERE IN THE DES MOINES AREA, AMES UP TO THE NORTH AS WELL. NOTICE THE STORMS ARE DIMINISHING IN STRENGTH AT THAT POINT, TOO. SO ONCE WE GET SECOND HALF OF TONIGHT, NOT AS MUCH OF A SEVERE THREAT, JUST SOME SCATTERED STORMS LEFT INTO THE PREDAWN HOURS OF TOMORROW ON OUR SUNDAY AND WE’LL KEEP THE SCATTERED STORMS GOING AS WE GO THROUGH THE DAY TOMORROW ON SUNDAY AS WELL. I MENTIONED THAT LOW PRESSURE CENTER YOU CAN KIND OF PICK OUT THE SPINNING MOTION OF IT AS IT KIND OF PINWHEELS SOUTHEAST ACROSS THE STATE. IT’S GOING TO DRAG THAT COLD FRONT EASTWARD AS WELL. AND SO BY TOMORROW AFTERNOON, YOU KIND OF PICK OUT THIS BROKEN LINE OF STORMS. WE’RE GOING TO WATCH THAT ONE TOMORROW, NOONTIME ONWARD FOR MAYBE THE POTENTIAL OF A BRIEF LITTLE WEAK SPIN UP TORNADO JUST BECAUSE WE GOT ENOUGH SPIN AND THOSE LITTLE AREAS OF SPIN GET PICKED UP BY THOSE STORMS AND THEY GET STRETCHED OUT AND YOU CAN FORM THOSE LITTLE FUNNEL CLOUDS. SO MAINLY IN THIS GREEN ZONE, EAST, CENTRAL, SOUTHEAST IOWA TOMORROW AFTERNOON, WE’LL BE WATCHING FOR THAT POTENTIAL. OTHERWISE, THIS IS A SCATTERED SHOWERS AND STORMS AND CLOUDS THROUGH THE DAY. TOMORROW ON SUNDAY, SUNDAY NIGHT. AND EVERYTHING WILL PROBABLY NOT WRAP UP FULLY RAIN WISE UNTIL WE GET TO MONDAY MORNING. AND BY THAT POINT, A LOT OF THE STATE’S GOING TO PICK UP A GOOD AMOUNT OF RAINFALL. SOME OF US ALREADY GETTING IT RIGHT NOW. GENERALLY SPEAKING, WE’LL BE LOOKING AT THE NORTHERN HALF OF IOWA WHERE YOU SEE THOSE PURPLISH SORT OF COLORS, MAYBE 1 TO 2, 2 TO 3IN WORTH OF MUCH NEEDED MOISTURE AS WE END THE WEEKEND. THENCE, WE GET TO EARLY NEXT WEEK, MONDAY, AGAIN, AN EARLY SHOWERS POSSIBLE AND THEN WE’RE JUST BREEZY THE REST OF THE DAY. HIGHS ONLY AROUND 80 BY THE WAY. TOMORROW WE GOT THOSE CLOUDS AND SHOWERS. ONLY 70. WE’LL KEEP

Storms tonight, then more rain Sunday

A few strong wind gusts, spin-up tornadoes, and heavy rain are all possible in Iowa the rest of this weekend.

Heading into tonight, our attention is focused on far western Iowa. This is where storms will form, then come eastward overnight.Low pressure is currently centered over southeast South Dakota. One boundary stretches south from the low pressure along the Missouri River valley. That part of Iowa is currently under a Tornado Watch until 10pm.Farther west, a cold front stretches from the low pressure center back into the Nebraska Sand Hills. This front will affect Iowa tomorrow.First off, the storms forming out in western Iowa will travel eastward tonight. They'll come into central Iowa toward 9-10pm, reaching the Des Moines area toward 11pm-12am. Tornadoes won't be likely by then, but a few of these storms still could produce some severe wind gusts before midnight.The storms will weaken to just scattered storms/showers the rest of tonight.TOMORROW: Scattered showers/storms will be around much of Sunday. The low pressure center will move from South Dakota across Iowa through the day. The numerous showers and the broad spin generated by the low pressure will mean a chance of funnel clouds during Sunday afternoon.The cold front will have swept into eastern Iowa by tomorrow afternoon as well. This front will be a zone to watch for a couple stronger storms again. A brief tornado can't be ruled out with any storm that gets more organized in that part of the state.Rain totals of 1-3" are also possible across the northern half of Iowa through Sunday. Storms aside, much of Sunday will be mostly cloudy and breezy. Temperatures should only reach the 70s.This system leaves Iowa Monday morning with a couple early showers, then skies will be drier later Monday into Tuesday. Temps around 80° and lower humidity will make a nicer start to next work week.Watches and WarningsInteractive Radar
