Dangerous Severe Weather Day Tomorrow To Our Southeast. Low Risk In Southwestern Lower Michigan

The SPC has made significant changes to the Day 2 Categorical Severe Weather Outlook. A significant severe weather day is in the cards for our neighbors to the southeast across much of central and southern Ohio and parts of east-central Indiana with "several intense long-track significant tornadoes possible" across the region.

NWS Storm Prediction Center - Day 2 Categorical Severe Weather Outlook (Moderate Risk - 4/5) [Issued: 2:00 PM/18Z]

Here in southwestern Lower Michigan, the SPC has expanded the Marginal Risk northward to encompass areas along and south of the I-94 corridor to account for the low "all-hazards" severe weather risk that has materialized here now that warm air will push further north than was previously anticipated. Isolated rumbles of thunder, associated with non-severe thunderstorms, will also be possible across the remainder of the WMIWX coverage area, especially along and south of the I-96 corridor.

All hazards are on the table here including the risk of a tornado or two, damaging wind gusts to 60 MPH, and large hail to 1 inch in diameter. This risk will be highly dependent on the northward extent and quality of the warm, moist air being transported into the region and the impact that pre-frontal and frontal rain showers that will be ongoing throughout the day on Tuesday have on the ability for the atmosphere to destabilize and support a severe weather threat.

We'll continue to monitor this threat and will provide updates as needed.
