Notes:
The data on this slide shows several NAM forecasts of 850 mb temperature valid at 00z on the 27th. The oldest forecast, from a run made on 18z on the 25th, is shown in the lower right, while the newest forecast, from a run on 00z on the 27th, is shown in the upper left. As was the case in the previous slide, this data indicates that the NAM was accurate and consistent with these forecasts during the 2 days prior to the storm.
