Awaiting Warmer Temps

Posted: 21 Apr 2023 05:30 AM

One of the more popular plots on the IEM website is a map of yesterday's four inch soil temperatures. It combines ISU Soil Moisture Network observations with a NWS weather model analyses. The page that provides that map has recently been updated to include a similar style plot of forecast soil temperatures from the NWS Global Forecast System (GFS). The featured loop presents a recent single run of the GFS model forecast out to early May with the average daily soil temperature at approximately four inch depth shown. This model run shows chilly temperatures over the coming days and a wait until early May for warmer temperatures to return.
