Severe Weather Set to Return Today

day1otlk_1300Thunderstorms have persisted over Iowa in recent days, but for the most part have remain isolated and/or below severe limits.  That could change this afternoon as a more organized threat of severe weather rears its ugly head.

You can see the area in the graphic to the left where the Storm Prediction Center has posted a slight risk for severe weather.  This narrow area focuses on a boundary that will set up shop somewhere over the state, most likely over portions of northern Iowa.

This boundary will serve as a focal point for severe thunderstorm development by late afternoon.  The atmosphere will be very unstable and a cap should be weak enough that storms can overcome it.  This explosive development should yield a few supercells, capable of all modes of severe weather.  Current parameters make the threat of large hail pretty low, but some shear could help produce a few tornadoes.  Overall the primary threat is strong damaging winds.
