Wednesday June 30 2021
A Heat Advisory has been issued for today in central Maryland around the Chesapeake Bay… not much relief from the water as the humidity will make it feel over 100ºF. An Excessive Heat Warning for metro Philadelphia, where it may ‘feel like’ over 110ºF this afternoon.
Morning Weather Set Up
The Heat Wave will peak today, and the end is in sight. The storm track will bring severe weather across the Ohio Valley to the Northeast.
The actual temperatures will come close to the record of 100ºF in Baltimore, set in 1959 and other prior years)
Severe weather will pass to our north, while some thunderstorms may drift into north central Maryland by evening.
The big storm day for us will be Thursday, then turning cooler into the July 4 Independence Weekend, with the risk of showers lingering.
As we finish out the month of June with heat, it might be easy to forget the chill we had as well.

Friday will start with a band of rain in the morning. This now appears to be passing south, while showers and storms will redevelop behind the front.
The chance of showers or T’storms will pop up each afternoon this weekend with cooler temps, but it will not be a washout.
7 Day Forecast
The Independence Holiday Weekend will be cooler. The rain on the graphic is NOT a washout, but there will be a chance for showers or storms each afternoon.
Next week, the heat will return.

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.
