Monday Afternoon Update

June 30, 2025

We continue to be stuck in a pattern with slow-moving thunderstorms that build in the afternoon and evening. With air temperatures in the 90s and dew points in the 70s, the air is juicy and can trigger torrential downpours.

Today’s first event was concentrated on the beaches with the heaviest rainfall lasting for hours along the Delaware seashore. Rainfall totals jumped up to 3 inches, and the radar has been impressive.

Flood Watch

The focus will be from 5 PM to 11 PM in metro Baltimore.

The atmosphere is primed for the next round of thunderstorms to flare up late afternoon and evening over heavily populated Central Maryland. There is potential for up to 2 inches of rain that may produce flash flooding.

Excessive Rainfall Outlook Today

The Slight Risk will follow the line of storms shown below in our simulation. This will include Southern Pennsylvania as well, even if not in the current watch… I would pay close attention if you are in the southern counties of Adams, York, and Lancaster.

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
