September 19 Late Summer Today Then Cooler Weekend
Friday, September 19, 2025
Today will feel like late summer as temps reach deep into the 80s. This will be after a start with fog on Maryland’s Lower Eastern Shore.
The next air mass with cooler air will arrive this weekend. Temps will drop into the 70s as winds shift to the East. This is worth watching because it may bring clouds and eventually showers for some areas, especially the mountains.
Next week brings the start of Autumn on Monday. The next cool air mass may bring rain and thunderstorms Tuesday night into Wednesday.
Tropical Storm Gabrielle is likely to remain East of Bermuda and not have an impact on the US coast.
WEATHER TODAY
Weather Warnings
Dense Fog Advisory On The Lower Eastern Shore of Maryland.
This lasts until 9 AM.
Surface Weather
The coastal storm is moving away, but it has left behind moisture. Areas that received moderate inland rainfall have developed patches of fog. The fog is thick farther inland, where visibility is under 1 mile. The fog will lift and allow for sunshine as a Northwest wind will develop.
A brief warm period will follow through tomorrow.

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
