Morning Report
For the most part we had a break from the widespread rain yesterday, but the risk for heavy downpours and severe storms comes back today and tomorrow. Part of the equation will be the increase in heat and humidity. A Heat Advisory is posted today for Delmarva and I expect that will expand to Central Maryland tomorrow.
Also on the list today is the potential tropical development in the Gulf. We need to watch this because whatever forms, regardless of getting a name or not, it will bring more heavy rain into the Southeast US and could reach us this weekend
Heat Index will be close to 105°F.
This is a ‘Marginal’ risk. That means that some, but not all, storms have a chance to reach severe levels with damaging wind, large hail, and a tornado.
Of all the storms, 15% may reach the rainfall rates to lead to Flash Flooding.
High Humidity combined with Heat is creeping back up the East Coast.
The old frontal boundary is stalled overhead and will increase the risk for strong to severe storms.
Attention on the Northern Gulf. Invest 93L is the low-pressure system that has a 40% chance of developing before making landfall.
There is still a 40% chance of tropical development. However, this will be close to land, and there will not be much room for development. Whatever does develop, even if it is not named, will bring additional moisture onshore and into the Southeast US. It is possible that moisture will reach us in the Mid-Atlantic this weekend.

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 while writing and to 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. #FITF
