Funnel Cloud in Iowa, June 13, 2005
A strong cap prevented convection from developing during the daylight hours. The cap weakened with sunset and allowed a mini-supercell to rapidly develop in a semi-moist atmosphere with plenty of vertical speed shear.

What happened
The episode as NWS DVN wrote it up.
A strong cap prevented convection from developing during the daylight hours. The cap weakened with sunset and allowed a mini-supercell to rapidly develop in a semi-moist atmosphere with plenty of vertical speed shear. Spotters, law enforcement, and the general public from Olin, Anamoso, and Monticello reported 1 and possibly 2 funnel clouds from the storm in a triangular area formed by the 3 cities.

Area forecast discussion, Jun 13, 1:44 PM CST, 6 hours 26 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE QUAD CITIES IA IL 244 PM CDT MON JUN 13 2005 .SYNOPSIS... UNSEASONABLY STRONG STORM SYSTEM TO SLOWLY MOVE ACROSS THE REGION THROUGH TUESDAY. PATTERN CHANGE ASSOCIATED WITH SYSTEM WILL BRING COOLER AND LESS HUMID CONDITIONS TO THE AREA FOR MUCH OF THE WEEK. && .DISCUSSION... FCST NOT OVERLY CLEAR CUT FOR TONIGHT. NONLINEAR PROCESSES ARE IN CONTROL WHICH WILL DETERMINE THE WHEN AND WHERE THAT CONVECTION WILL OCCUR. ONE FACTOR THAT MAY BE PLAYING INTO ALL THIS IS THE DRY ANTECEDENT CONDITIONS WHICH MIGHT PREVENT ANY WIDESPREAD CONVECTION. WILL BE MAKING LAST MINUTE ADJUSTMENTS TO TONIGHT AFTER OBSERVING SATELLITE TRENDS. TUESDAY THROUGH WEDNESDAY EVENING AREA UNDER STRONG CYCLONIC FLOW WITH INDIVIDUAL IMPULSES MOVING ALONG IN THE FLOW. SHOULD SEE SOME DIURNAL CONVECTION ON TUESDAY WITH THE BETTER CHANCES ACROSS THE NORTH. WEDNESDAY MORE OF A QUESTION MARK. MODELS DON/T REALLY SHOW ANY IMPULSE IN THE FLOW ALOFT AND OVERALL CYCLONIC FLOW IS NOT NEARLY AS STRONG. THERE MAY BE A WEAK IMPULSE THAT IS BEING SMOOTHED OUT BY THE MODELS SO WILL GO WITH EVEN LOWER CHANCES FOR SHRA WITH AGAIN THE BEST CHANCES NORTH. THURSDAY THROUGH MONDAY LOOKS TO BE QUITE ATTM. LOW LEVEL EASTERLY FLOW DOMINATES FOR SEVERAL DAYS BEFORE TURNING TO THE SOUTHEAST. MAIN BENEFIT IS COOLER TEMPERATURES AND LESS HUMID CONDITIONS. && .DVN WATCHES/WARNINGS/ADVISORIES... IA...NONE.
