August 13 More Humid With Afternoon Storms And Update On Tropical Storm Erin

Wednesday, August 13, 2025

Morning Report

Summer has surged back. Yesterday was the first day this month that reached 90 degrees in Baltimore and Central Maryland. The humidity has crept up, and now we have weakness in the atmosphere to help develop showers and thunderstorms.

There is a marginal risk that some storms will turn severe. Tomorrow there may be some showers as well, but a drop in humidity will bring sunshine and quiet weather into the weekend.

Tropical Storm Erin is still racing across the Central Atlantic Ocean. This is still expected to become a strong hurricane AND CURVE AWAY from the East Coast. The latest look is below.

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
