The daily feature title today is a bit of acronym soup with NBE MOS an abbreviation for National Blend Extended Model Output Statistics. The NWS has an excellent website explaining the National Blend and a fancy website called DESI to view this data. The featured chart is an IEM data presentation of the time lagged range of NBE max and min temperature forecasts for Des Moines along with the actual airport observations. It is always informative to see if the observations are falling within the range of forecasts to see how well these forecasts are performing. Of note for this featured chart is upcoming warmth forecast with very warm overnight low temperatures forecast. The peak warmth appears to be Christmas Eve and Christmas Day with some cooling into next week.
