Baltimore city and county tops in rainfall stats
The stats are coming in from Thursday's record-breaking rainfall, and it looks like locations in 
Baltimore County and in the city topped the charts, with totals of well over 3 inches in some locations.
In fact, an observer in Pimlico, in Baltimore City, reported 3.86 inches - the highest in the tallies so far from the National Weather Service or the CoCoRaHS Network. I also had a call this morning from a reader in Pikesville who recorded 3.9 inches on his rain gauge.
We had 3.10 inches on the Weather Deck in Cockeysville. And The Sun's weather station at Calvert and Centre streets recorded 2.69 inches for the storm.
Many Harford County locations also reported rains in excess of 3 inches.
The official count at BWI-Marshall Airport was 2.61 inches for the date, and 2.63 inches for the storm. That broke the 1.74-inch record for a March 10 in Baltimore, set in 1883. Average March rainfall for Baltimore in March is 3.93 inches, the second-wettest month of the year after September.
Here are the first returns from the National Weather Service:

The heavy rains are still running off the land and into area rivers and streams. Many are running at record-high levels for the date. Check out this streamflow map from the US Geological Survey. Dark blue dots represent flows over 90 percent of the record. Black dots indicate record high flows.

Our rain gauge in Reisterstown had just under 4 inches yesterday!

We don't have a rain gauge but, for what it's worth, I dumped about 4 inches of water out of our recycling can when I got home from work Thursday, and it was still raining. We are in Pen Lucy/Waverly.
