This page presents daily soil temperature analysis maps. The left hand column plots combine ISU Soil Moisture Network observations and bias corrected NWS NAM forecast model analyses to produce a higher resolution plot. The values plotted represent a daily average with the ISUSM stations being averaged between the daily high and low value and the NAM Model representing an average of six hour interval data. The right hand plots are simple GFS forecast model outputs without any bias correction.
