National Weather Force has issued a Severe T-Storm Advisory effective from 3 PM to 1 AM central time for conditions right for severe storms.
Zones affected: northwest, west, north, central, & northeast NE; northwest, north, central & northeast IA; southeast SD.
Discussion: A clear boundary runs from northern Nebraska to southern Minnesota. With temperatures heating up south of this boundary and stronger winds from the south by late afternoon, scattered thunderstorms are expected to form near the front. Steep mid-level lapse rates, combined with efficient moisture and ample shear, will enhance the storm potential. The significant instability will create a risk for a few severe storms with multi-cells capable of producing damaging winds and large hail.
There will also be some low-level shear, allowing for a few storms capable of producing isolated tornadoes if they can maintain their strength. These storms are anticipated to form around 3 PM and continue throughout the evening and overnight, potentially becoming a line as they move through the Iowa area.
Main risk: large hail, damaging winds, isolated tornadoes and CG (cloud to ground) lightning.
Stay tuned for more updates.
