Understanding this agricultural product
Delta-T is air temperature minus wet-bulb temperature. Larger values indicate greater evaporative demand. These maps use the regional GFS fields supplied to the agricultural processing script.
Automated model guidance · Forecast lead time is measured from the model run, not from the time you open this page. Read the local valid date and time on each map.
