May 20 Weather Poor Air Quality But Help From Ocean Winds

Thursday May 20 2021

The trade off from sunshine and light winds has been building pollution levels. The Clean Air Partners have our region in Code Orange Air Quality Alert for today. That is unhealthy for sensitive groups, and given the added awareness of COVID-19, here’s a reminder of the suggestions from 11 AM to 5 PM:

Limit physical outdoor activities.

Limit Driving (to lessen pollution).

Put off lawn care.

Morning Surface Weather

High Pressure remains in control, which is why we have had light winds to allow pollution levels to build up. Notice the boundary along the coast. There is another air mass trying to build in with winds from the ocean. This should reach Delmarva today, and metro areas on Friday for a brief cool down.

Still very warm west of the Chesapeake Bay. But that wind shift should cool down Delmarva.

Temps should be a little cooler with that new air mass. The heat and a little more humidity will return this weekend.

We will remain on the perimeter of rain, which a 30% chance of showers over the weekend afternoons.

The pattern should break down next week.

Sunshine State Of Mind

I am done with the cold and snow (for the season). I am embracing my wife’s mantra of Sunshine State of Mind.

This was designed by Shannon Berk and we will be wearing it through spring and to the beach.
