Narrative:
The ASOS unit was reporting VFR conditions (measured 9500 ft broken visibility 10+ mi) when a thunderstorm moved through the airport area causing the tower visibility to go below 2 mi. No one is authority/authorized to augment the ASOS unit at pne. I had several planes wanting to land and depart at that time. Then when the thunderstorm left, the ASOS unit reported IFR conditions when the WX was VFR.
