HI of 109° in Clarksville and 106° in Poolesville. These are in open, meadow-like areas well away from concrete. Legit.

I think the dewpoint might be lower tomorrow and Friday - upper 60s to around 70 instead of what we're seeing today.

I can't even count how people I know who wish they had never gotten involved with solar power companies.. A staggering number of lawsuits have been filed against solar power companies. I know a guy who worked for a solar power company and he refused to have solar panels installed on his home lol

It is quite impressive to see 8 states (IL, IN, OH, KY, plus DE, NJ, CT, and RI) completely covered by Extreme Heat Warnings: I don't know the last time that I have seen a Midwest heat wave also extend far into the Northeast (especially northern New England) simultaneously like this.

Here in Carlisle just after 12:30pm...the temperature is 94.6 degrees with a dew point of 80.2 degrees. This combination creates a heat index of 115.2 degrees. These numbers are already ridiculous and set to be worse tomorrow. Dew Points of 80+ degrees are not common in our part of the country. It's nearly impossible to exceed a dew point of 83 degrees. It's way too dangerous to go outside for any period of time (for we seniors). I'll update again in the next hour or two. I think 100 degrees here is a possibility, but less than 50% likelihood. Some locations around the LSV are going to reach heat index values of 120+ degrees. Personally, I think I've only ever witnessed an HI at or over 120 degrees maybe 2-3 times my entire life (and I'm 66). I just keep praying for all of us that we don't have brown-outs or worse yet, black-outs. Time will tell.

Dinner in the pool! If it's in the evening it should be good to hold.

I have a swim team event tomorrow next to the pool deck for 2 hours tomorrow. It's a team dinner event and I think its a good idea to cancel it with HIs near 110 degrees expected but was wondering if you or another met have any opinions.

How does that compare to the bank thermometer?

Looks like there are some legitimate 80 degree dew points showing up. KDNN (Dalton) is registering 90/80 with a HI of 107. My PWS has spiked to an 82 degree DP which is the highest one I have ever recorded.

A far cry from July 4, 1776. Weather report from the pen of Thomas Jefferson. Guess he would have been in the NE Forum...

i noticed the PI is thriving this year. i try to stay on top of it and spray it with a targeted weed spray every year (I use poison ivy killer, only targets viney stuff including oriental bittersweet), this year the plants are bigger with huge leaves. good luck with the knotweed, there are a bunch of different removal strategies out there (most are voodoo), but unless you use ROund Up or similar, you are unlikely to succeed

The mesos have backed off on the storm chance today. There will still be some storms around but they’ll be more isolated.

Never a legit heat wave without clouds moving in to cap the temps.

94 here at 12:15. I have my annual AC maintenance today - funny timing there.

The real big heat arrives here tomorrow. You'll be in DCL with a grin on your face

Heat Index 111 before noon in Leesburg, gross .

I have a larger system, so may calculated break even was slightly longer. However, the way I look at it is electricity is not something I can really opt out of. So I'm either paying for electricity or paying for panel financing. I've been able to get that price down around what my monthly electric bill was anyway, so my only real cost is to stay connected to the grid.

88/74 HI of 98 in Orlando for god's sake.

I was hoping the drought would help keep the DPs down. That is not happening. 91.4/76

June rainfall 1.87” imby/Columbia

Classic ROF setup the next few days for northern parts of the subs, certainly an upside to the center of the ridge ending up flatter and further SE than originally expected...
