Storms Tuesday

July 27, 2015

We are tracking a cold front. It is forecast to move through eastern Iowa Tuesday afternoon and evening. A few storms are forecast to develop along and ahead of the front. The more sunshine we have, after the morning clouds, the better chance we have at severe storms. Primary threat will be high wind, large hail and heavy rain.

Funnel Cloud

July 27, 2015

Early this afternoon, around 2 pm, we started getting reports of a funnel cloud and photos followed shortly after. The location was near La Porte City. The atmosphere was not favorable for a tornado to form where reports of the funnel cloud were. The image below shows a few rain showers near Grundy Center and any storms were well southwest of that. The funnel cloud was not associated with a thunderstorm. A few have asked why the warning sirens were not sounded.  The reason is because there was no threat of this becoming a tornado.
