August 10 Flood Watch For Strong Storms Later Today
August 10 2022
Wednesday Morning Update
We are about to have a pattern change in our weather, but it will be a bumpy ride. Today will get in to the lower 90s in metro areas with high humidity, storms will develop and turn strong to severe. The biggest risk will be heavy rain and flooding.
FLOOD WATCH
As of now, a Flood Watch is in place for Baltimore through Southern Maryland where rainfall could reach 1 to 3 inches (or higher).
Two model radar simulations below suggest heavy storms will reach metro Baltimore this evening.
Morning Surface Weather
We have a very muggy morning, and a quasi-stationary front. The combination of more heat will help ignite a new storm complex that will reach us later today. My concern is the Mesolow Pressure will enhance the storm activity and crank up the risk for heavy rain and severe elements.
Morning Temperatures
Look at these numbers from around sunrise…. Upper 70s and lower 80s across central and southern Maryland.

Comparing the NAM 3 Km to HRRR Models
There are some slight differences here, and I must reiterate that these models have not performed well. The tendency is for storms to develop and arrive a little earlier and become more widespread than shown.

*Disclaimer due to frequent questions:
I am aware there are some spelling and grammar typos. 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 at my second year at Cornell. It didn’t stop me from getting my meteorology degree, and being first to get the AMS CBM in the Baltimore/Washington region.
I do miss mistakes in my own proofreading. The autocorrect spell check on my computer sometimes does an injustice to make it worse.
All of the maps and information are accurate. The ‘wordy’ stuff can get sticky.
There is no editor that can check my work when I need it and have it ready to send out in a newsworthy timeline.
I accept this and perhaps proves what you read is really from me…
It’s part of my charm.
