June 29 Weather: Heat Wave Reaching Peak Then Turning Stormy

Tuesday June 29 2021

A few things have happened since my last report as my time now is being split with training for Maryland Trek 8. 

Any outdoor activities will be tough for the next few days with dangerous heat, then a couple of stormy days as the pattern shifts.  But if we compare to other areas, it is not nearly that bad.

To our south, Tropical Storm Danny was named and made landfall Monday afternoon with 45 mph winds, and that storm is now. Small cluster of clouds near Atlanta.

The Bermuda High pumping our Heat Wave helped to push that storm inland and missing us.

Pacific Northwest: Monday Highs

Records have been blown up! Areas that set all time records on Sunday, surpassed that Monday. 

Seattle/Tacoma WA: 108ºF, beat their prior record of 104ºF on Sunday. This was their 3rd day in a row with 100ºF+

Dallesport, WA: 118ºF marks the highest ever in the state

SO HOT… Many highways had road surface buckle in the heat!

We have another pavement buckle, this one on northbound I-5 at NE 195th St. The two center lanes are blocked. The HOV lane is open to ALL traffic in this area. pic.twitter.com/fk2Vk7VBjh

Mid Atlantic: Monday Highs

Temps reached the lower 90s, with 80s by the water. It will turn much hotter over the next few days, but still nothing like the NW states. 

We are about to get out peak of the heat over the next two days.

Looking Ahead

The heat wave will collapse with a slow moving cold front. This may bring severe storms with local flooding Thursday, and may repeat on Friday depending on how far east it can move.

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.

Double Benefit: Proceeds will be split between our nonprofit Just In Power Kids and the development of my new weather website. That has been scheduled to be ready to launch in May.
