Becoming from 0700 to 0900 (and thereafter) wind 130 degrees/ 05MPS (metres per second? not overly familiar with that one) 4000 metres horizontal visibility in Mist (BR), broken cloud, base 700'.
In normal words, wind from the south east at x speed, 4000 metres of vis, misty, cloud from 700' covering at least 5/8 to 7/8 of the sky.
In practical terms, ok for IFR ops, not good for VFR ops.
