April 2018: Cold Locally, Warm Globally

Much has been written about the cold weather experienced during the month of April 2018 across much of the United States, especially the central and eastern United States.  Indeed, the country experienced its 13th coldest April since record-keeping started in 1895 and its coldest since 1997.  Two states, Iowa and Wisconsin, had their coldest Aprils on record and were colder than their respective previous records by more than 1.5 degrees Fahrenheit.  At the same time, April snow cover reached its fifth-highest level since records started being kept in 1966.

However, April was far from a cold month across the rest of the globe.  Globally, April was the third warmest on record, with particularly warm anomalies present across Europe as well as the Arctic and Antarctic regions.
