A COLD FRONT WILL PUSH EAST INTO WESTERN IOWA THIS MORNING - FORCING SHOWERS AND STORMS EAST ALONG WITH IT. CENTRAL IOWA WILL BE SANDWICHED BETWEEN TWO SYSTEMS - WITH HEAVIER RAINFALL IN NRN AND SRN IOWA. POW CTY SHOULD COME OUT THE WINNER HERE WITH THE LEAST RAINFALL OVERNITE. ISOLATED SEVERE STORMS WILL FORM ALONG THE FRONT - APPEARS RIGHT NOW, SOUTHEAST IOWA WILL GET THE BRUNT OF THE SEVERE WEATHER THIS EVENING/OVERNITE. THE MAIN THREAT WILL BE WIND AND SMALL HAIL - WITH UP TO 3 INCHES OF RAIN FROM SIGOURNEY SOUTH, AND EAST.

Thursday and Friday 23rd/24th - Windy/Tstorms
Saturday thru Thursday 25th thru 30th - UNSETTLED/SHOWERS - WHY UNSETTLED? THE GULF OF MEXICO IS GETTING READY TO EXPLODE IN STORM ACTIVITY. THE HURRICANE SEASON IS AT IT'S PEAK, AND WITH THE LACK OF ANY LANDFALL STORM IN THE CONUS, THE SEASON HAS SOMEHOW TAKEN A BACKSEAT TO LOCALIZED WEATHER. THAT'S ABOUT TO CHANGE......
THE WEEK OF THE 25TH APPEARS TO BE A PRIME TIME FOR GULF OF MEXICO DEVELOPMENT. IF THIS HAPPENS, THE OVERALL PATTERN WILL CHANGE GREATLY FROM THE GULF COAST, NORTHWARD. THIS COULD/SHOULD BE A BIG ONE. TROPICAL FORCE WINDS MAY PUSH AS FAR NORTH AS SRN MO - ALONG WITH RECORD RAINFALL FROM THE COAST OF TX OR LA, NORTHWARD TO MO AND INTO THE OHIO VALLEY....THE REAL KICKER TO THIS? WE MAY SEE TWO (THAT'S 2) STORMS IMPACTING THE U.S. COAST AT THE SAME TIME. ONE ALONG THE TX/LA COAST, AND THE OTHER IN THE SE U.S...... TIME WILL TELL............
On this day in Iowa weather history...
