September 2 Slowly Warming This Week And Needed Rain From Thunderstorms By The Weekend
Tuesday, September 2, 2025
Our unseasonal chill finally has something to show for it. After August ended with temperatures 3.5°F BELOW AVERAGE, yesterday produced a new record low of 52°F in Baltimore.
While still cool, today’s temperatures will not be as chilly. This is a signal of a slow warming trend for the week ahead.
The lack of rainfall is becoming an issue again. It has been nearly two weeks since we had any rainfall. The next chance of rain will be with scattered showers and thunderstorms on Thursday and again on Saturday.
Looking ahead, the cool pattern will relax and bring us another push of warmer air in the middle of next week.

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 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
