Upcoming warm stretch will be the longest in a generation

CEDAR RAPIDS, Iowa (KCRG-TV9) -- Tomorrow is the beginning of what will be a very unusual stretch of weather for February. All of the area will have multiple straight days in the 50s – in fact, it’ll challenge the most consecutive 50-degree and 60-degree days on record.

At the Eastern Airport, the most straight days of 50 or warmer in February is seven days, which happened in 2000 and 1981. Records there go back to the 1950s; the long-term climate site in Marion had eight straight days of 50 or warmer in 1930. The current expectation is for at least eight days in this upcoming warm-up!

What about 60-degree days? The Eastern Iowa Airport had three in a row in 1981; the Marion observer had four in 1930. Once again, this record will be in jeopardy since we’re forecasting four such days as of Wednesday afternoon.

This spate of mild days is rare for everybody in eastern Iowa, not just Cedar Rapids. For most, it’ll be the longest stretch of such mild February weather in about 35 years and will approach the all-time streaks that were, for the most part, set in 1930.
In Dubuque, the record number of consecutive days of 50 or warmer in February is eight, set in 1930. The record number of straight 60s is five, also in 1930.

Iowa City’s airport was a short period of records; the long-term climate site at the wastewater treatment plant on the southeast side of the city dates back to the late 1800s, though. There were eight straight days of 50-plus weather in 1981 and 1930, and it turns out all eight of them were in the 60s!

In Waterloo, the record for consecutive February temperatures of at least 50 degrees is also eight, which happened in 1930. That same stretch produced seven straight 60-degree days.
