Hottest October day ever: Record breaking temperatures soar from Midwest to the South
Dangerous, record-breaking heat is taking over the South and Midwest.
In Ohio, all classes and after-school activities at Columbus City Schools were canceled Tuesday due to the heat.
These cities not only broke daily records, but broke the record for hottest October day:
-- New Orleans: 95 degrees
-- Nashville: 98 degrees
-- Indianapolis: 92 degrees
-- Huntington, West Virginia: 95 degrees
-- Pensacola, Florida: 96 degrees
-- Mobile, Alabama: 96 degrees
But at the same time, the West felt like winter on Tuesday: temperatures reached 37 degrees in Billings, Montana, and 47 degrees in Idaho Falls.

Meanwhile, residents from New Mexico to Michigan are under flood alerts. Some cities, already drenched, could see more than 4 inches of additional rain through Thursday.
Near Duluth, Minnesota, some roads were already submerged under water as heavy rain fell and rivers neared record flood stage.
