7/20/2013 8:00 AM 1.97 0.0 M 0.0 M Downpours from late afternoon thunderstorms were very localized to a narrow strip through northwestern Anne Arundel County according to radar estimation, mesonet and other CoCoRaHS reports which indicated little or no rain at many nearby locations. I was not in the area for this storm, so I questioned some area residents about it. One, who is of retirement age and lived in this area for a very long time, and lives about a half mile NE of my rain gauge claimed to have gotten 4" in a very short period of time and observed what was by far the most intense rainfall ever seen by this person while some areas only a mile away got very little or no rain. There was evidence of a great difference even across my tiny property. When I returned a few days later, the front lawn was only slightly wet, and the soil in plant pots was dry with the plants in need of watering. Meanwhile, less than 10 meters away in the rear of the house, where my rain gauge is sited, soils were still soggy. Could it be that if this account told by the nearby resident is not exaggerated, that the one-minute rainfall record at Unionville, MD was exceeded in a small part of this neighborhood?
