This animation shows pressure in the middle of the troposphere, roughly 5 km above the surface, from June 21 – June 24. The field shown is 500 hPa geopotential heights. Reds indicate higher pressures and lows indicated lower pressures.

  2. This is nothing compared to the polar vortex and heat dome from a few years ago

  3. I’d love to know the relationship between pressure and the temp. My suspicion isn’t a direct mapping.

  4. Everyone just go outside and blow towards the ocean, we’ll be alright

  8. that’s the heat dome we have every summer i. texas. been wondering why it’s been so mild lately.

  9. Here in Utah it was in the low 60s to 70s for the highs. Unusual for this time of the year when we are normally mid to upper 90s.

  10. I’m in the worst of it here in Virginia. It’s hot out. My plants are suffering!

  11. Currently 76° in Orange County, CA absolutely unbearable out.

  14. How does measuring the height of a specific pressure compare to the pressure on the ground? Too much variation in the ground readings?
