Cold air which accumulated over portions of the United States and Canada sent temperatures dropping on April 4, 2018, breaking records.

The temperature in Omaha dropped to -10.5 °C (13 °F) on the morning of April 4, a full 2.7 °C (5 °F) lower than the previous record for the date, set in 1899.

Other communities setting daily records included Grand Island (-10 °C / 14 °F), North Platte (-10.5 °C / 13 °F), Sioux City (-13.9 °C / 7 °F) and Valentine, the state’s coldest spot, at -15 °C (5 °F).

The normal high for early April in the Omaha area is 15.5 °C (60 °F), while the normal low is 1.7 °C (35 °F).

What’s impressive about this outbreak of cold is that the northern US and Canada have been the coldest part of the Northern Hemisphere over the last three weeks — in terms of temperatures departing from normal, said Jack Boston, a meteorologist with AccuWeather Inc.
