Strong System To Bring Severe Weather Tuesday; Tornadoes Included


A powerful spring storm system will sweep through the plains on Tuesday with all modes of severe weather likely so read on for the details…

Our next storm system is currently stationed in western Utah late this morning and will continue to pull to the east later tonight into tomorrow. Tuesday will feature mostly cloudy skies but eventually cloud cover will thin out by about the mid afternoon time frame. This will be enough for rich amounts of instability to build into the area. A warm frontal zone will setup shop across the center of the state by Tuesday afternoon/evening which will send temperatures into the 70s along the front, maybe even some 80s not out of the question here. The timing will be key as a very narrow corridor of upper 50/lower 60 dew points will be found across west central to southwest Iowa.

The latest thinking is that we will stay fairly capped into the late afternoon and then storms should explode after 6 PM across western Iowa where all modes of severe weather are likely, including tornadoes. The dynamics should be enough to promote a elevated tornado risk for at least a few hours Tuesday evening. Storm cells should then form into a squall line with main threats of damaging winds and hail and wouldn’t even rule out a few spin ups. That line will press east into eastern Iowa overnight into early Wednesday morning.

The other part to this forecast will be the strong winds from the system. We will start off Tuesday with southeasterly winds sustained at around 15-30 MPH which will have gusts ranging 30-50 MPH. Then by Wednesday the wind will switch around to the west/northwest with another round of gusts 25-40 MPH. Thursday will feature the strongest gusts through the entire system with gusts 35-55 MPH, the strongest gusts found across the northern half of Iowa. The last round of gusty winds will hit Friday with gusts 30-50 MPH before the system exits.
