Breaking the Blue Streak

Posted: 15 Mar 2019 05:32 AM

While the major storm system this week brought high winds, rain, fog, and a blizzard to folks north and west of Iowa, it also brought some warm air to the state. The featured chart shows daily high temperature departures for Sioux City. The days below average are colored blue and the chart nicely shows that our recent two days of warmer temperatures finally broke the long running streak of below average since early February for the site. This sudden warm-up and rain has a downside though with widespread flooding now due to frozen soils and ice jams. The good news is that the next week looks mostly dry with above freezing daily high temperatures.
