A temperature swing of 40-degrees is expected over the next 48 hours across the state. But, before the warmup, National Weather Service meteorologist Roger Vachalek says another blast of bitterly cold air will push into Iowa. “Low temperatures overnight tonight will hit around 10-below-zero near the northern border, while central Iowa and the southern portion of the state will be near zero to five above,” Vachalek says.

Much warmer air will begin to move into the state tomorrow (Thursday). “During the afternoon, we’ll warm up about 20 degrees or so and should be in the teens to lower 20s throughout central and northeast Iowa, with temperatures in the upper 20s and lower 30s in the southwest,” Vachalek says.

High temperatures on Friday and through the weekend should climb into the 40s. “We may even see highs reaching 50 on Sunday and early next week, there’s the possibility of temperatures in the mid-to-upper 50s returning to the state of Iowa,” Vachalek says.
