Severe Weather Update #1 - July 7

A Severe Thunderstorm Watch has been issued for portions of South Dakota, Nebraska, Minnesota, and Iowa until 10:00 PM this evening. This watch will cover the four corners of these states, thus including a majority of the counties within the Sioux Falls NWS CWA. Additional thunderstorms have formed outside of this watch area along a warm front/outflow boundary across portions of Iowa. These storms are expected to remain below severe limits, thus no watches or warnings have been issued for this area.

Forecasts and analysis of ongoing convection indicates that the severe weather threat for northwest Iowa will likely not come into play until the evening hours (after 5 PM).
