The US heatwave

I am growing increasingly concerned about the potential for a long lived, and potent heatwave taking shape over much of the eastern half of the US, but particularly the east coast. Unlike severe storms which you can chase, these things you shouldn't and depend on factors you cant see directly. Do not overextend yourself. It will start building on 6/30/2026 and will be in full swing 7/1/2026. 

The key ingredient is what's called a high pressure area, air sinks in these regimes. Clouds don't typically form and the very building blocks that form storms aren't present here. Hot air exists here because the sinking compresses the air-mass near the surface. High pressure does not move? Boom, heat wave. 

Be prepared for the potential if you live south of the Mason-Dixon line and in the great plains for high's to reach or exceed 100F (37.7c) for an extended stretch of time. In the ozarks-northeast, the humidity will be a problem rather than the raw temperature. 

Extreme heat warnings (dark pink), heat advisories (orange), and excessive heat watches (blood red), are already populating across a huge population base already. Tread lightly.
