6/30/2012 8:00 AM 0.32 0.0 M 0.0 M Derecho struck this neighborhood at 10:55 EDT Friday evening well ahead of the storm's rain and while thunder was still distant. Near-hurricane conditions lasted nearly ten minutes and subsided as rainfall arrived which was only moderate. Lightning was frequent, mostly to south, till 11:30 with light to moderate rain. Then light rain continued with decreasing frequency of lightning till nearly 1 AM and ended completely shortly after 1 AM. Electric failed a few minutes before the derecho and remained out as of early Saturday afternoon when I left for relatives in Pennsylvania with my perishable refrigerator contents and eventually entered this report from there. So although the winds were ugly, the rain was gentle and beneficial.

This "stray" storm was strongest t-storm of this year so far including the 29 June derecho, nearly equal in wind but much greater in rainfall, longer duration, and much more loud thunder. Storm was very localized as some areas only a couple of miles away had very little or no rain. Indeed, sky was never really dark during the storm indicating sun was out close by. Preliminary rainfall amounts in 8/02/2012 Significant Weather Report were slightly under-reported. Any hail would have been small and would have fallen when I was not looking.
