May 18 Monday Morning Report
Thank you for reading this post, don’t forget to subscribe!
We are now entering the feel of summer for three days! Afternoons will reach the 90s with increasing humidity, and mornings may stay in the 70s for many. This will push the need for air conditioning!
CODE ORANGE AIR QUALITY ALERT
We also have light winds and the build up of pollution. A Code Orange Air Quality Alert has been issued for today and tomorrow. The combination of pollution and higher sun angle with high heat will build ground level ozone that will be felt by sensitive groups with breathing issues, very young kids, and the elderly.
Heat Compared To The Records
A strong cold front will spark storms likely to turn severe Wednesday afternoon and night, then slowly slide south on Thursday. The winds will shift from the East, which is a cooler and damp flow from the ocean. The end of the week may stay in the 60s for most of us, while daily rain showers may extend into Memorial Day Weekend.

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 can also 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
