Narrative:

A severe thunderstorm over chs airport; the rain falling in sheets; wind blowing; wsp ribbon display barely showed the wind blowing. With little to no pcrn on final or over the airport; the wsp went nuts with windshear alert and microbursts with the windsock hanging straight down and no movement to the trees near the tower. PIREPS were smooth (during the alerts) and at the most +/-5 KTS on final. This forced aircraft to stay away.
