The Fire Danger Index will remain in the “Extreme” category in Shelby County, at least until the next update, on Thursday. Emergency Management Coordinator Bob Seivert says field work is beginning in the County, and there are typically three or four combine fires each harvest season. Seivert says while the short grasses have greened-up thanks to recent rainfall, the major fuel source for explosive fire growth…corn, beans, and tall grasses.. continue to dry-up due to the sunshine and wind.
Extra precautions should be taken while farmers are out in the field, to ensure their machines are free of debris and that fires are not started behind those implements while the harvest is underway.

The unofficial end of summer is here and fall-like scenery could be arriving earlier than usual this year. Iowa Department of Natural Resources Forester Mark Vitosh says this summer’s drought has stressed some trees, which may speed up the process of leaves changing color. “In parts of central Iowa, I’m already starting to see some fall color, which is an indication those plants are deciding to shut down early and try to adapt to the conditions that are here,” Vitosh says. During a typical year, the fall colors are at their most brilliant in October.
Vitosh says the change in leaf color could climax a few weeks earlier this year. “We actually got a similar response in 2008 with the floods. We had a lot of stress on plants in some of the bottom lands and those trees started to turn color,” Vitosh says. “We may see a similar response this year because in some of the flood plain areas, those soils can be rather sandy and we haven’t had a lot of moisture.” A worst case scenario for fans of fall foliage would be almost no change in color. “The other thing that happens with a drought, instead of getting fall color, you get a lot of nothing…a lot of brown or yellow or the trees just shut down. So, we may not get the brilliant colors,” Vitosh said.

TODAY AND TONIGHT: CHANCES FOR THUNDERSTORMS INCREASE ACROSS THE AREA TODAY INTO TONIGHT. THERE IS A SLIGHT RISK FOR SEVERE WEATHER THIS AFTERNOON INTO TONIGHT…WITH LARGE HAIL AND DAMAGING WINDS THE MAIN SEVERE THREATS.
SCATTERED SHOWERS AND A FEW ISOLATE THUNDERSTORMS ARE POSSIBLE LATER THIS MORNING. SEVERE STORMS ARE NOT ANTICIPATED WITH THIS ROUND OF STORMS…BUT MAY BE POSSIBLE LATER THIS AFTERNOON. A WEAK FRONTAL BOUNDARY WILL SAG SOUTH TODAY AND WILL BE THE FOCUS FOR THUNDERSTORMS INTO THE EVENING. A QUICK MOVING UPPER LEVEL DISTURBANCE WILL AID THUNDERSTORM DEVELOPMENT THIS
AFTERNOON. STORMS COULD BECOME SEVERE LATER THIS AFTERNOON WITH DAMAGING WIND AND LARGE HAIL THE PRIMARY HAZARDS. IF CLOUD COVER PERSISTS THROUGHOUT MUCH OF THE AFTERNOON…THIS WILL LIMIT THE INSTABILITY AND SEVERE STORMS WOULD THEN BE LESS LIKELY. ANY SEVERE STORMS SHOULD REMAIN GENERALLY SOUTH OF INTERSTATE 80.
