Tuesday Night Update
June 24 2024
This recent heat wave may have produced some 100 degree temps, but the official number for Baltimore at BWI was 99℉ not reaching the record 100℉ set in 2010. If BWI stays above 76F by midnight, we will have the record warmest Low temp for the date.
If you heard about a higher number, that was at The Inner Harbor Weather Station, which does not comply with NOAA standards and thus not official. I do not usually mention it because I do not deal it accurate, but it did highlight the urban heat island:
Heat Advisory is a downgrade with heat index values expected to stay below 105℉: This includes Central Maryland and Central Virginia.
A Heat Warning is posted for where it may reach 110℉: This includes Delmarva, Southern Pennsylvania, and metro Philadelphia.
There will be a line of thunderstorms trying to form ahead of a cold front… with will eventually cross the region and end the heat wave. The energy is limited, but the high heat and humidity can still ignite a few very strong storms capable of damaging wind, large hail, and an isolated tornado.
The cold front was located….
Once again the city may be in the 80s, while most of the suburban areas will be in the mid to upper 70s.
We will watch the start of storms shortly after noon, then the typical time window between 3 PM and 8 PM.
Jet Stream: 500mb Geopotential Heights
Wednesday to Sunday
The expectation is for a daily cycle of afternoon and evening thunderstorms that will pulse up, then settle down after dark…only to retire again the next day.
Set the forecast on repeat the rest of the week.

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
