This sprawling storm system coincides with the arrival of an Arctic air mass that will consume much of the country “this upcoming week”, according to the National Weather Service. Between Tuesday and Saturday, temperature highs are expected to average from 10 to 35F below normal from the north-west to the eastern two-thirds of the US.
In the northern plains and upper midwest, temperatures could plummet into the negative teens fahrenheit and extend into the central plains. From the midwest to the mid and northern portions of the eastern seaboard, temperatures are expected to fall into the single digits and teens, the meteorological agency said.
Even the southern US will not be spared, with temperatures potentially dropping in portions of normally temperate states such as Florida and Texas. The northern Gulf Coast might see below-freezing temperatures, according to the Weather Channel.
