🌪️📅On this day 2 years ago... a historic, record setting storm moved through Iowa.

Prior to 2021, only 5 tornadoes had occurred in Iowa during the month of December since 1950.

But on Dec. 15th, 2021 more than 𝟏𝟐𝐱 that number occurred in a single day! (1/?)⬇️⬇️⬇️ 🌡️Many who were in Iowa will remember unusually warm temperatures before the storms started on Dec. 15th 2021. This day shattered multiple daily high records by nearly 20° F and surpassed the all-time state record for December with a high of 75°F in Oskaloosa! (2/?) Image
