Remarkable Warm Front

11 Mar 2026 05:30 AM
A significant severe weather event developed on Tuesday from northern Illinois/Indiana back southwest into Texas. The rough weather clipped southeastern Iowa as well with powerful storms developing during the late afternoon hours along and near a very strong surface warm front. The featured screenshot is from the ISU Soil Moisture Network homepage showing 3:30 PM air temperatures over southeastern Iowa on Tuesday. The 81.5°F plotted was near West Point and the 59.4°F was just over 30 miles away to the north near Crawfordsville. This temperature contrast made for a remarkable warm front due to the large temperature change over a very short distance. Strong warm fronts like these are typically trouble for severe weather as storms are focused along the boundary and the boundary helps to provide spin to the storms to produce large hail and even tornadoes.

Strong Warm Front

05 Apr 2023 05:29 AM
Tuesday was a another wild day of weather in the state with tornadoes, large hail, damaging winds, and a very strong temperature gradient over the state. The featured chart looks into this gradient by plotting the maximum difference in air temperature by state by hour based on available airport weather station data. Four states along the warm front are highlighted with the maximum hourly value shown in the chart legend. Iowa's 50 degree difference was beat both in Kansas at 59 and an amazing 73 degrees in Nebraska. So your location made a big difference if yesterday felt like summer or it felt like crummy early spring weather. The good news for warm weather lovers is that the forecast continues to be bullish for a significant stretch of warmer weather starting later this week and into next week and beyond.
