After a record breaking cold night last night, tonight could break some more records especially in the eastern part of the state. Cedar Rapids broke their record low Saturday morning with a 49°. Sunday morning and even Monday morning could break a few more records before temperatures begin to rise. Highs will generally be in the 70s and lower 80s entering this upcoming week with nighttime lows rising from the lower-mid 50s to near 60 by mid-week. A few chances of showers and thunderstorms are possible as well beginning on Tuesday.
