June 23 Another Record High Possible With Heat Advisory And NOAA Severe Storm Risk

Sunday, June 23

Morning Report

This heat wave has lived up to expectations. On Saturday, a new record was set at Baltimore’s BWI airport when a temperature of 101ºF was reached. The high temperature is expected to possibly reach 100ºF again today, which would break another record.

When including the high humidity, the Heat Index will again push 105ºF to 110ºF, making it uncomfortable and dangerous to be outside. It may be no surprise that another Heat Advisory has been issued.

Strong to severe thunderstorms (Slight Risk) may develop after 3 PM as a cold front arrives and interacts with the high heat and humidity.

Heat Advisory Today

A very good chance to break another record high. The Heat Index will feel like 105ºF to 110ºF.

Baltimore Record High: Sunday, June 23 = 97ºF set in 1894 and 2010.

NOAA Severe Storm Risk

This ‘Slight Risk’ is level 2 of 5 and includes Southern Pennsylvania to Central Maryland and parts of Delmarva. Storms have the potential to produce:

• Flash Flooding
• Damaging Winds over 58 mph
• Large Hail over 1-inch diameter
• An Isolated Tornado

Alert Reminder

• Watch: This may be issued when conditions present themselves to have the POTENTIAL for Severe Weather. This alert may cover a 6 hour period and cover many counties.
• Warning: This is issued when severe storms have developed and are being tracked. This alert will usually last 45 minutes and include a county and specific towns with a timeline.

Morning Surface Weather

While still warm and humid, there are more clouds around this morning. The main event will be the strong cold front that will arrive later today and ignite some strong to severe storms.

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
