Hazards Expected Saturday Afternoon and Evening

What Is Limiting the Tornado Threat
Despite the severe weather setup, forecasters note that high dew point depressions, low-level dry air, and crosswise vorticity will considerably limit the tornado threat with this event. However, mesoscale interactions could still favor tornadogenesis with the more robust storms that develop, meaning a tornado cannot be ruled out even with the limiting factors in place.

- Hail — Broad hail probability area with a hatched significant hail zone indicating 2-inch or larger hail probability
