The upper level ridge that had been over the region weakened on the 25th as an upper level storm system moved across the area. This allowed for numerous showers and thunderstorms to develop during the afternoon. Enough instability was present for a few of these storms to become severe. Copious amounts of moisture also existed, allowing these storms to produce very heavy rainfall as well.
