We continue to keep a very close eye on the forecast for Tuesday. The Storm Prediction Center has placed all of the state of Iowa in a slight risk of severe weather for Tuesday. All three modes of severe weather (large hail, damaging winds, and tornadoes) will be possible by Tuesday afternoon.
Storms will begin to develop across eastern Nebraska on Tuesday and will push to the east into western Iowa. Storms initially will be discrete, and this is when the best tornado potential will be. Storms will then quickly merge together into a line. This is when the tornado potential will transition from a tornado threat to a damaging wind threat with wind gusts in excess of 60mph. Large hail will also be possible with these storms. This line of storms will continue to push through the state, making it all the way to the east side of the state.
Rain will then become more widespread Tuesday evening into the early morning hours on Wednesday. Another concern with this system is the heavy rain potential. Rainfall totals of 1 to 3 inches with locally higher amounts will be possible by Wednesday. This may lead to flash flooding Tuesday evening. Remember to turn around, don’t drown.
