The format of the files are as follows:

I6 - Station ID
I2 - Unused (District code?)
I4 - Data year
A4 - Data type
     PRCP - precipitation daily accumulation (hundredths of inches)
     TMAX - maximum daily air temperature (F)
     TMIN - minimum daily air temperature (F)
	For precip:	        366 F4.2
	For temperature:	366 I4
Missing values are denoted as 9999
Day 366 of non-leap years is denoted as 9999
