Wind/Temp Text (FB Winds)

The Winds/Temps text data are the official FB Winds product from NCEP. This provides winds from 3000 to 53,000 feet out to 6, 12 and 24 hours. The data is extracted from model output for individual airports represented by a 3 letter IATA identifier. The data are grouped by region. Here is a sample:

The data block shows ddffttt where dd is the wind direction in 10s of degrees, ff is the win speed in knots and ttt is the temperature in Celsius. At higher levels, the sign for the temperature is not needed since it's assumed all values are negative. If the first digit of the wind direction is greater than 4, then the wind speed is greater than 100. For example, 810550 would be 310 degrees (80-50) at 105 knots and the temperature is -50C.
