Overview

A strong storm system impacted the forecast area on March 14, resulting in a multitude of hazards seen through the afternoon and evening. Through the late morning and afternoon hours, the storm system created quite the strong wind field throughout much of the Midwest, resulting in widespread strong winds gusting upwards to 40-55 mph through the day. These very strong winds combined with dry antecedent conditions led to a very high fire danger area-wide, prompting a Red Flag Warning. Several fires resulted from these conditions, with gusty winds aiding the spread of the fires.

Not only did we have an active start to the day with winds and fire weather conditions in place, but the system also brought a line of showers and severe thunderstorms through the area that evening. While lightning activity remained on the low-end, convection that developed was able to mix down the strong winds aloft, causing damaging winds to occur at the surface. This resulted in widespread 60-80 mph winds, with some locations that saw over 80 mph. With such strong winds, numerous power outages were noted throughout the area. These winds also resulted in damage to trees, structures, and power poles/lines. In Johnson County Iowa, lightning struck in a field of timber, resulting in a fire that the strong winds spread for about 25 acres.
