Meteorological Data Arrives

My contact at the United Kingdom Meteorological Office came through. A package containing upper air wind speed/directions (winds aloft) for August 4th arrived two days ago. A very quick analysis indicates strong southwesterly winds at flying altitudes persisted for the period. I haven't checked to see if forecast data was included in the package, if so, it will be interesting to see how far forecasted conditions were off from actual conditions.
