July 21 Morning Storm Recap And Weekend Weather Looks Better

July 21, 2023

Friday Morning Update

The expected round of morning storms lived up to expectations and then some! If you woke up to thunder and heavy rain, you are not alone. The eruption of the storm line brought loud thunder to most and the heaviest downpour to the part of our region with the most severe drought.

This storm line held together crossing the Bay and Delmarva… leaving an improvement moving in this morning.

While we could have a pop-up shower in the afternoon, the weekend will be less humid and warm.

Radar Recap: 2:15 AM to 6 AM

Rainfall Total: Doppler Estimate At 6 AM

The heaviest rain fell in southeastern Carroll County. South of Westminster to Mount Airy, over 2 inches fell, with some spots getting over 3 inches of rain. A widespread 1 inch+ of fresh rainfall covered much of the region.

Drought Report

I shared this map yesterday showing the Severe Drought in the same areas of Carroll, Frederick, and western Howard Counties. Click the image for the full report.

Morning Surface Weather

This line of strong and severe storms will continue to move east and off the coast this morning. The actual cold front is to our west and will pass through later today. Most of the energy has been used up, however, some isolated storms may still pop up.

With the morning storm gone, the cold front may ignite some isolated showers or a T’storm… even at the beach.

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 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.
