The wider storm

A large-scale mid-level trough nudged out into the Northern Plains while a strong frontal boundary moved out across the Dakotas. Storms initiated with up to 3000 J/kg elevated CAPE near a surface boundary. Storms quickly organized into a linear system with short bowing segments which produced gusts of 60 to 75 mph. A large trailing stratiform precipitation shield developed featuring a strong wake-low an hour or two after the strong thunderstorm outflow winds with gusts up to 70 mph.

Began near Arlington (44.3000, -97.1300).
