Ice storm warnings and winter weather advisories remain in effect across the state as multiple waves of freezing drizzle and freezing rain move through the area, causing significant impacts across eastern Iowa. Closures | Interactive Radar | Weather Warnings The heaviest freezing rain overnight was concentrated in southeast and east-central Iowa, affecting areas around Ottumwa, Oskaloosa, Chariton, Centerville, Bloomfield and Grinnell. The ice storm warning still applies here. This area of ​​heavy freezing rain will continue to move north over Marshalltown and Waterloo by 6 a.m. Further freezing rain showers are expected until at least 10 a.m. before temperatures finally rise above 32 degrees and the melting process can begin. ¼ to ½ inch of ice accumulation is possible in the warning area, resulting in very hazardous travel conditions and possible isolated power outages. Limit travel in this area if possible until conditions begin to improve this afternoon. Rainfall has been much lower so far in south-central and central Iowa. There have been a few rounds of light freezing rain or freezing drizzle in the Des Moines metro, but so far the light precipitation has limited ice accumulation to a glaze and road conditions are still good. However, untreated surfaces are slippery. A round of more persistent freezing rain is expected around 4am, likely leading to more slippery patches. Another round of freezing rain may occur between 6 and 8 a.m., which is likely to have the greatest impact on the urban area. However, due to reduced precipitation, ice accumulation should be limited to about a tenth of an inch. This still results in slick driving conditions, especially on roads that have not been treated or where the treatment is beginning to disappear. Temperatures along and south of I-80 should begin to climb above the freezing mark beginning at 9 a.m., bringing the ice threat down and road conditions begin to improve throughout the morning and into the afternoon. However, isolated showers and some heavier downpours are possible until at least 6pm, meaning the wet weather is likely to continue throughout the day. North of I-80, it will likely take until just before noon for temperatures to climb above freezing, extending the threat of freezing rain a little longer and creating hazardous travel conditions into the early afternoon. The situation is expected to improve by the afternoon as everyone sees temperatures rising to over 30 degrees. The storm was expected to leave the entire region in the early evening hours. Patchy fog and cloudy conditions will persist into Sunday, but it is expected to be a slightly warmer day with highs around 40 degrees, so remaining ice is expected to melt away. Monday will see even warmer conditions with highs reaching the upper 40s. Cooler weather is expected for the remainder of next week, but no major winter storms are expected at this time.
