The culmination of a week of rain came with widespread severe weather in the Mid-Atlantic. It is ironic and yet somewhat common that we can get more storms on a day with marginal risk than when we have a higher risk from NOAA…. Like we did the day before.
A strong cold front moved through to spawn multiple storm cells. Our region is in a moderate and growing drought, and while some areas received over 6 inches of rainfall, most of the areas did not. So our drought watch will continue.
The focus of the most intense storms was from Washington, DC along Rt. 50 to Grasonville with wind damage. Pockets of wind damage events were scattered across Southern Maryland and northeastern Maryland to metro Philadelphia.
On the edge of that storm, large hail fell over Anne Arundel County, about 10 to 20 miles Northwest of Annapolis.
A complete list of local storm reports from The National Weather Service in Sterling, VA is at the bottom of this post.
Vivid and intense cloud to ground lightning along with loud thunder was very prominent in Anne Arundel County. It is important to note that the most dangerous lightning is before the first drop of rain. That is when many people are still outside, regardless of severe storms or not.
This shows the build up of the storm over Anne Arundel County, MD. The pink shade over Odenton, Gambrills, and Crofton between 2:45 to 3 PM was the peak of that cell… Then it expanded across I-97 and dumped heavy rain through the central Chesapeake Bay region.
Below is a look at the rainfall estimates from Doppler Radar. I zoomed in on different areas to show how localized the heavy rain was measured.
For a storm to be considered severe, the hail is measured as larger than a quarter or one inch in diameter.
This storm over Odenton produced hail up to 1.5 inches.
John Reilly shared this coverage of hailstones on his deck.

I shared this on my Facebook page. The impression of how large these hail stones were can be seen splashing in the water. Thanks to Kati Bethuy for sharing this.
This wide view shows how local the pockets of heavy rain were. Notice the Yellow shade was over 6 inches north of Baltimore and between Elkton MD to Metro Philadelphia.
Baltimore City had between 1.5 and 3 inches of rain. There was a pocket of 6 inches of rain around Perry Hall.
Baltimore’s BWI recorded 1.77 inches of rain, yet there is still a deficit of 7.46 inches for the year. So we are not out of the drought.
We can see the pockets of heavy rain. That hail storm near Odenton and Crofton pulsed 3 to 4 inches of rain.
Annapolis got around 2 inches, with between 1 to 2 inches crossing Kent Island.
There was a sharp cut-off west of the city. Carroll County is parched. While Eldersburg got around 1 inch of rain, much less to nearly nothing fell on Mount Airy up to Westminster.
Farther west around Frederick, they have missed many storms that have broken up or split around the mountains. The wind flow from the west will often result in that downslope or rain shadow effect.
There were some pockets close to 1 inch of rain east of Salisbury and around Ocean City. Most of the area got under 1 inch.
This low cloud is common on the front edge of a strong to severe storm.
Derek Rogge said this dropped and then lifted. This is often thought to be a funnel cloud with a forming tornado. However, it is more likely a low-level condensation and non-violent event. This can form with high humidity and be moved and shaped by rising updrafts.
Scud stands for Scattered Cumulus Under Deck
This low circulation did give some the impression there was a tornado, but that was not the case.
Jacob Sprankel thought he spotted one from his drone over Columbia.
Was reviewing some drone footage and discovered a possible brief tornado touchdown just east of Columbia. What do you think? 🤔🌪️ #MDwx pic.twitter.com/EpPGYwamb0

I am aware there are some spelling and grammar typos, and occasional other glitches. I take responsibility for my mistakes, and even the computer glitches I may miss. I have made a few public statements over the years, but if you are new here you may have missed it: I have dyslexia, and found out during my second year at Cornell University. It didn’t stop me from getting my meteorology degree, and being first to get the AMS CBM in the Baltimore/Washington region. One of my professors told me that I had made it that far without knowing, and to not let it be a crutch going forward. That was Mark Wysocki and he was absolutely correct! I do miss my mistakes in my own proofreading. The autocorrect spell check on my computer sometimes does an injustice to make it worse. I also can make mistakes in forecasting. No one is perfect predicting the future. All of the maps and information are accurate. The ‘wordy’ stuff can get sticky. There has been no editor that can check my work when I needed it and have it ready to send out in a newsworthy timeline. Barbara Werner is a member of the web team that helps me maintain this site. She has taken it upon herself to edit typos, when she is able. That could be AFTER you read this. I accept this and perhaps proves what you read is really from me… It’s part of my charm.
