Cedar Rapidsí temperature fell all the way down to -19 degrees Monday morning. This was the coldest official airport reading in Eastern Iowa Monday morning, and it set a new record low for Feb. 10. The previous record low for today was -18 degrees, which was set in 1901. Waterloo and Iowa City both fell to -16 degrees, while Dubuque had a low of -17 degrees. Those laws were not cold enough to break records in those cities.
Another very cold night is ahead. There's a good chance of temperatures falling even colder than what we had Monday morning. Skies will be clear again, but winds will be even lighter, which will allow temperatures to plummet. We are forecasting a low of -20 degrees in Cedar Rapids and Iowa City, -22 degrees in Dubuque, and -23 degrees in Waterloo.
Record lows for Feb. 11 are -20 degrees in Cedar Rapids, -20 degrees in Iowa City, -18 degrees in Dubuque, and -24 degrees in Waterloo. All of those records were set in 1899.Some favored river valleys, such the Wapsi, Maquoketa, and Turkey, may have localized readings of -25 or colder Monday night.
