The dark color represents a freeze warning, light blue indicates a frost advisory.
Some much colder conditions have moved into Iowa and National Weather Service meteorologist Brad Fillbach says the first hard freeze of the season for much of the state will arrive early Saturday. “We’re looking at lows in the mid 20s to mid 30s across the state. We do have frost advisories and freeze warnings out,” Fillbach said.
The freeze warning for 1 a.m. to 9 a.m. Saturday covers much of northern, eastern and southeastern Iowa. High temperatures today are forecast for the 40s and 50s. Warmer weather will return soon.
“Saturday’s highs will warm back up into the 50s, with 60s by Sunday and Monday,” Fillbach said. Some areas of the state should have temperatures in the 70s on Monday and Tuesday.
The first rain chances in several weeks may arrive next week. “We do have chances early next week, but the chances are fairly slight and what rain we do get doesn’t appear to be of any significance,” Fillbach said. NOAA’s Climate Prediction Center released its winter outlook Thursday and it calls for a slightly warmer-than-normal winter in Iowa, with near normal precipitation.
