High of 71 this weekend in the PNW!
Oh baby I’m right in the center of the bullseye. Sun-Wed is going to SUCK
finally its not over us in the pnw, halleluiah
I assume that dong shaped cool section on the west is to with the mountains/Yosemite and not because my British family are on holiday there?
I feel this could be a big factor on Trump’s policies. HVAC issues in the form of labor (ICE) and parts (China tariffs) shortages are going make large areas uninhabitable due to the heat and humidity.
Can’t wait to sit through temps of 100 degrees up in Connecticut
It’s days like these that make me glad I moved to Western New York. The winters are not as tough. We will be lucky if we hit 85 next week, with lows in the 60’s.
Why do they have cuba so excellently detailed but don’t include any of the great lakes? What if an mf lives in ohio, how are they supposed to find their state???
This is what I’d call beautiful data. Thanks.
Flat earthers will take issue, but stuff ’em.
So hot the Great Lakes dried up.
Low of 80s in DC is unbearable. I’m so grateful to have central air conditioning. Horrible for those that need to work outside, or don’t have air conditioning. Dangerous heat.
Tuesday looks to be 101 here in Boston. Monday at 96. That 101 is 2 off from a june record
Why did you choose the forecast for June 24th?
Lines for land mass need to be a different color, I was struggling to figure out what the heck I was looking at for a second
90+ coming to Illinois. Greeeeat
It’s impossible to have normal weather in fucking Maryland. Its either 99% humidity, heat dome, no rain for months but max pollen, severe weather….swamp nuts or desert conditions. 10% humidity in the winter.
For fucks sake
It’s freaking brutal here in Memphis and it’s only 83 degrees. Feels like 95.
Why are you giving Americans units of distance they’ll never hope to understand?
Blessed to be in the non red area.
Where the hell did the Great Lakes go?
This is all a Chinese hoax Trump said.
Don’t worry, FEMA has everyone covered in the event that NOAA says this is a cause for concern. If it gets bad enough we might even have to dip into our own USAID account to help out our citizens united.
Part of the super power of living in Texas is that I’m so oppressed by my government, the heat is the 5th or 6th thing I complain about now!
DC is gonna melt. Not looking forward to additional irrationality from the US Capitol.
What is the relevance of 500 hPA? What does it mean?
Loving the coastal bay area weather… Low 50’s at night all summer.
this is not a map of (just) the US
Who produces such a map. Where the hell are the great lakes. Without them it’s incredibly difficult to tell where exactly is the defining lines.
