11:45am UPDATE: Serious 48 Hours Taking Shape Across Iowa

day1otlk_1630The potential for a major outbreak exists both today and tomorrow in the Upper Midwest.  Earlier we talked about Iowa’s target for Monday, we’ll have an update on that threat later this afternoon.  This post will focus on a threat that could stretch well into the overnight hours across western and central portions of Iowa tonight.

As you can see in the graphic to the left, the Storm Prediction Center has much of the state under a slight or moderate risk.  This is in connection with a storm system of which the center will be focused in the Nebraska area today.  Even so, a warm front will push from south to north into Iowa later tonight, bringing with it a volatile threat of strong to severe thundestorms.

Even after sunset, all modes (including tornadoes) will be possible across central and western Iowa.  But the greatest threat will come in the form of strong damaging winds and large hail.

day1probotlk_1630_hailTake a look at the graphic to the right, it shows the risk area for severe hail.  You can see the high-end moderate risk that exists, especially over western portions of Iowa.  Again we expect Iowa to remain dry for the most part today, but severe weather should develop or move into the state by late this afternoon or even after sunset.

We’ll continue to monitor the latest trends and bring you the latest information as it comes in.  We also plan to launch our live coverage tonight when/if needed.
