These maps are based on the NOAA GFS Forecast Models and as such are calculated models so it's possible that actual weather conditions may depart significantly
from those being predicted. Once NOAA's system has completed it's calculations we download the data (well over 2 Gigabytes of data) and run our own forecasting models in order to create the images below (in excess of 1600 images are generated by the DuggleNet wx-Server every night!).
The lower left corner of the maps shows the "Run" time - this is the time when the modelling is started. The "Valid" time, on the right, is the time to which the map relates. Since the data processing by NOAA's computers takes some time to complete, the run-time is always a few hours before the data is finally released.
Our DuggleNet maps are generated & updated daily at 03:00 local time using OpenGrADS and sequenced using JQuery. All times on maps are Zulu-Times, which is the same as GMT/UTC-time. Move your mouse over the timeline to see the images animated throughout the forecast period.
