Wild Wednesday?

risk Over the past few days we have been keeping our eye on a large storm system that could bring heavy rains into states like Iowa and Wisconsin, to severe weather from Missouri down to Oklahoma.  Starting late tonight, rain will move in from the west and could bring potential strong to severe storms south of interstate 80 with hail being the main threat. The rain will then continue to the east into the morning hours Wednesday and continue throughout the day. There will be periods of thunderstorms Wednesday into the early evening hours, and it is possible once again that a few of these may be strong to severe with large hail being the main threat. As the storm system continues to the east, cooler air will start to build in behind it which could transition rain over to snow Thursday night into the morning hours on Friday. Accumulations do look to be possible the further north  and west you travel in the state. Snowfall totals will have to be monitored as they have been inconsistent, but as it stands now, moderate snowfall totals are possible in northern Iowa. Once this storm finally pushes out of here midday Friday, much of the state will see impressive rainfall totals. The heavier totals will be over the southeast two thirds of the state where rainrainfall accumulations over 3” will be likely. Because of this, much of Eastern Iowa is under a flood watch due to the fact many rivers will approach or exceed flood stage.

On the other side of this storm, there is a large area of severe weather potential. This area spans from Illinois to the southwest towards Texas. Areas in the red from the picture above are in a moderate risk of severe weather. This is the area that can expect the highest potential for severe weather where all modes of severe weather are likely. Areas in the yellow are in a slight risk, this does include the far southeast corner of Iowa, and this is the area that will see large hail, damaging winds and a few tornadoes. This area will have to be monitored as it is possible that the severe risk could expand to the north more. Once all said and done, we will dry out Friday afternoon and will stay that way through Saturday as rain will return by Sunday and persist through the bringing of the work week.
