Current 48hr Forecast Map

Forecast models postprocessors generate MOS (Model Output Statistics) which are statistically derived surface conditions for particular cities. Two types of plots include forecast surface conditions from the NAM model as well as maximum temperature predictions from the GFS out to 7 days. There are MOS based meteograms which give a graphical representation of the weather conditions for the next 60 hours for individual cities. The NAM plots are updated once every 12 hours at around 12:15 EST. The GFS plots are updated once a day at around 8 AM EST.
