Narrative:

En route tul on dec/sat/95, ASOS WX reported C4 overcast with 2 1/2 visibility. Shot CAT I approach to runway 18L and went missed approach at 200 ft with rabbits not in sight. Turned around and shot CAT ii approach to runway 36R and landed successfully. WX as reported by ASOS was 'inaccurate' to say the least.
