MOS Forecasting

Posted: 11 Oct 2016 05:34 AM

The featured chart displays the combination of MOS forecasts of morning low temperature and afternoon high temperature for Des Moines this month. Model Output Statistics (MOS) forecasts take raw weather forecast model output and using past forecasts with actual observations, attempt to provide a more accurate forecast. These forecasts are made four times per day, so the bars represent the range of values forecasted as the forecast is updated with time. It is interesting to note the cold weather forecasted for tomorrow, with the highs only in the mid 50s!

Good = 10
Bad = 0
Abstain = 1
