July 11 With A Dry Heat Today Air Quality To Hit Code Orange For Some

July 11, 2023

Tuesday Morning Update

High Pressure is building in and in this stage, we continue with the low humidity. It is the hottest time of the year, so with typical sunshine it will easily hit 90ºF for many.

While the ‘dry heat’ will be comfortable, the light wind will allow pollution to build in the urban centers. That is why a Code Orange Air Quality Alert has been issued between Baltimore and Annapolis, Maryland.

The heat and humidity will build in quickly over the next few days, so enjoy what we have now.  We will introduce storms again starting Thursday.

Morning Surface Weather

High Pressure has carved out quiet and dry weather for a few days.  The light wind is the reason the pollution will build up in the urban centers.

Air Quality Forecast

The CODE ORANGE includes Baltimore City and around the Beltway down through Anne Arundel County. This is NOT from wildfire smoke. It is simply the light wind, high temperatures, and daily build-up of air pollution.

Afternoon Temperatures

A break from the heat and humidity AND it looks like no smoke from Canada as well.

7 Day Forecast

This technically shows a heat wave, but what I find more important to highlight is the combination of high humidity with the warmest day Thursday, introducing more strong or 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 predicting the future. All of the maps and information are accurate. The ‘wordy’ stuff can get sticky.  There has been no editor that can check my work when I needed it and 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 able. 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.
