Advice from Ryan Zimmerman, a local metereologist: Have those weather radios handy! This is a developing weather situation. If anyone is outdoors this afternoon, please keep an eye to the west and southwest. Storms could very well become widespread this afternoon and these storms may easily become severe in a hurry. It may be a good idea to move any barbecues and picnics indoors today.
