The Global Forecast System or GFS model is a 384-hour model for short and medium range forecasting. This model is updated 4 times per day and is good for viewing changing weather patterns over the next week or more.
-
Locate storms and 6hr precipitation potential
-
Shows 12hr precipitation potential
-
Maximum surface temperature forecast
-
The wind speeds are shown in color contours, the heights in solid white lines and the vectors show wind direction and speed.
-
The North American Mesoscale Model (NAM), is also known as the WRF or NMM. The model is run 4 times per day out to 84 hours. It provides finer detail than other operational forecast models.
-
Maximum surface temperature forecast
-
Locate storms/6hr precipitation potential
-
Determine precipitation type (rain,snow,ice)
-
Determine how close air is to saturation (clouds or precip. potential)
-
Used to determine jet stream position (around 33,000ft)
-
The European Center for Medium Range Weather Forecasting (ECMWF) Model runs out to 7 days and provides data at 24 hour intervals for sea level pressure, 850mb winds, temperatures and 500mb heights. These plots are generated once a day at 8:45 PM EST
