September 13 Storm Reports Cooler Air Moving In And Pushing Hurricane Lee
September 13, 2023
Wednesday Morning Update
Strong storms overnight overachieved in central Maryland. The bulk of this event was in metro Baltimore and up to the Northeast, which was south of the posted Flood Watch. The heaviest rain did fall in Baltimore City with a storm that also prompted a tornado Warning overnight.
As a result, there was local flooding and many downed trees this morning, which has resulted in power outages as well.
First, we will recap this storm, then our local weather. It is this new cool air mass that will push Hurricane Lee off the coast, but it still may make landfall in Eastern Maine this weekend.
Doppler Radar Recap 10 PM Tue to 12:30 AM Wed
The heaviest storm was around midnight as expected in my last report.
This first view has higher resolution but may only cycle through once. You can refresh to repeat or see the loop below A glitch made that a little fuzzy.
Doppler Radar Recap 10 PM Tue to 12:30 AM Wed
This is the same time frame looping but the glitch in my program made the resolution poor.

RESTATING MY MESSAGE ABOUT DYSLEXIA
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 the 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 at predicting the future. All of the maps and information are accurate. The ‘wordy’ stuff can get sticky. There has been no editor who can check my work when I need 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 available. 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.
