National Weather Service in Duluth Updates Forecast Model
After noticing errors in their predictions, National Weather Service in Duluth has upgraded one of its computer forecast models.
The particular model updated is one that has been tested for over two years. Normally, models are updated once or twice in a year according to Joe Moore, Warning Coordination Meteorologist for the National Weather Service in Duluth.
The big reason for the upgrade was that it was miscalculating two major things this past winter.
“This model is used primarily for what we call ‘medium-term,’ your next five- to 14-day forecast,” said Moore. “The old version of this model had an issue with cold and particularly snow, it tended to overdo the cold.”
The forecast model went into effect on March 22.
