Narrative:
WX is IFR low ceilings and varying visibility due to rain. The ASOS is kicking out special WX observation faster than controllers can cut ATIS messages, most of the time the ASOS is lagging behind the WX conditions. ASOS has increased controller workload to the point where controllers are ignoring the special WX observations that it continually transmits. This ASOS should be decommissioned.
