Evening Temperature Crash

Posted: 12 Feb 2020 05:48 AM

The featured chart is from the bufkit warehouse website visualizing various forecasts of air temperature going forward for Des Moines. The timestamps on the x axis are in UTC time and show a significant crash in temperature this evening from the mid 30s to about negative 10 by Thursday morning. The concern with this forecast is a flash freeze situation as any rain and slushy snow will quickly freeze and be difficult for treatments to effectively remove from roadways.
