Here's UI-View's "help" on weather data format if it's any help... e.g.

272/000g006t069r010p030P020h61b10150

272 - wind direction - 272 degrees
010 - wind speed - 10 mph
g015 - wind gust - 15 mph
t069 - temperature - 69 degrees F
r010 - rain in last hour in hundredths of an inch - 0.1 inches
p030 - rain in last 24 hours in hundredths of an inch - 0.3 inches
P020 - rain since midnight in hundredths of an inch - 0.2 inches
h61 - humidity 61% (00 = 100%)
b10153 - barometric pressure in tenths of a millibar - 1015.3 millibars
