Saturday storms dropped 7 inches on St. Michaels

Maryland rainfall

Saturday's rainstorms produced widespread street flooding in St. Michaels. I know because I had to detour through the village to get around the high water. So did plenty of other motorists. It took us a half hour to get through. Firefighters manned the intersections and roadblocks. Easy to see why folks there don't have basements.

But it wasn't until I checked the rainfall totals tonight that I finally understood what we had experienced. St. Michaels recorded 7.7 inches of rain in the 24 hours ending at 8 a.m. Sunday. That's the equivalent of two month's rain in a day.

The heaviest rain seems to have been concentrated in a very small area of Talbot County. Here are more rain totals from CoCoRaHS.  Other spots in Talbot saw 3.5 inches or less, while the Baltimore region recorded only a quarter- to a half-inch. Amazing.

The rainfall map above reflects all rain for the week ending Sunday July 11. Orange indicates 4 inches or more. Red is 5 inches and up.

I understand the Philly area had heavy rains as well. Here in northern Carroll County, we had 0.28" as recorded on the rain gauge on my brand new weather station - the first rain since I installed it.

I am not sure how much rain we received in Abingdon. But I know at 5 AM, it was a thunderstorm with very heavy rain and then, it rained for most of the day thereafter up until the night. While the heavy rain stopped by noon, the slow steady rain continued. So, while we didn't get as much rain at St. Michael's, I am sure we got more rain than the airport recorded.

FR: You're right. The map shows very heavy precip in southern Harford County, too. Forest Hill and Bel Air both reported more than an inch.

did anyone else see a crazy meteorite on july 11th around 12:30am or 1am? I was on route 50 and looked out the window around mardela springs. it was so bright!
