Heat Dome

[Anonymous]

I know a thread is incoming, so might as well start now.

I recommend you increase your AC set point a couple of degrees higher, to not over-stress your system.

Does anyone know if this is going to be a humid/thunderstormy heat, or a hot dry heat?

I’ve noticed from living here for almost 50 years, that in the summer, when it gets above 95 degrees, the likelihood of afternoon thunderstorms occurring and cooling things off diminishes rapidly. At 100 degrees, there’s almost zero chance of a afternoon storm. It will just stay hot into the night.

Storms here occur most frequently at temps in the upper 80’s with high humidity. It’s easier for the air to reach saturation in the 80’s than in the upper 90’s because you need a LOT more water to get there than is required in the 80’s.

So I would not expect afternoon storms if temps are already mid-90’s by lunchtime.

It’s weird because the weather app on my phone has already walked it back until this coming weekend - 95, 99, 96 on Friday-Sunday only and low 90s other than that. (And lows in the mid to high 60s during the week which would be uncommon with low 90s later in the summer!) But weather.gov has us hitting the mid 90s on Tuesday. Guess we’ll see what happens!

You're probably right!

It'll probably just be hell-hot, without the thunderstorms. The plants will suffer, sadly.

I can't wait until October

A heat dome is just a high pressure system. They're just inventing new words to scare us.

My weather app for Montgomery County is showing 95 on Friday and 98 Saturday. It will be especially jarring since I just got back from the Pacific Northwest coast with highs in the 50s. Sigh.

Google is your friend or the capital weather gang. Heat and humidity taking heat index to up to 105 on Saturday. Was invited on a kayak camp trip on the Patuxant. Will not go.

Exactly this.

Just gullible fools being scared by a fearmongering media.

The derecho was on a 100 day degree day, I remember seeing the temperature on my phone earlier that day on a walk and being surprised by it. So if you do get a storm on a 100 degree day, safe to say it isn’t good.

Rwnjs post crap like this on every post about extreme weather. They are trying to shut down any discussion of global warming since they don't believe it is happening.
