July 13 Weather Developing Another Strong Heat Wave

Saturday July 13, 2024

Morning Report

Baltimore hit 82ºF yesterday as the rain kept us cooler. The latest numbers for BWI continue to show 24 days total at or above 90ºF. We are about to add more to the list, including maybe a few days near or above 100ºF with this new heat wave.

A disturbance is still stuck along the coast, so we continue to have rain this morning near Baltimore, across Delmarva to the Beaches. This may last into early afternoon, then eventually fade. But some downpours are still possible in this region.

Inland, we will see the leading edge of the new air mass building in a strong heat wave that will continue into the week ahead.

Within this next surge of hot air, there may be a few impulses of strong to severe thunderstorms in the evenings and at night. There is some relief expected by the end of the work week.

Heat Wave Records To Consider

The excessive Heat Wave building in may only bring one or two challenges to record highs (in Baltimore). Here are some high marks to pay attention to. The best chance we will have will be on Wednesday to match the old record.

• Sunday July 14: 101ºF in 1954
• Monday July 15: 102ºF in 1995
• Tuesday July 16: 104ºF in 1988
• Wednesday July 17: 101ºF in 1988

The line of rain is associated with the nearly stalled disturbance. Pockets of rain between Baltimore and Delmarva may produce a few downpours through the early afternoon. This will slowly shift east and gradually fade later today.

Looking Ahead: Best Chance For Late Day Storms

Within the Heat Wave, there will be some disturbances that may bring enhanced late-day or evening storms. Working off the high heat, there may be some potential severe weather in addition to local downpours.

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
