A mid-winter mini-heatwave tied or broke long-standing high temperature records across at least 3 states on January 19, according to preliminary reports from the National Weather Service (NWS). The 65° at Omaha absolutely crushed the previous record for the date of 60°, which dated back 119 years to 1895.
