Currently in Denver - July 18, 2022

The weather, currently.

Just an awfully hot day for Monday, July 18th

I may or may not have let out a four letter word this morning when looking at the model data for how hot it will be on Monday. Get ready to blast your AC because we have triple digits coming! At least there is a slight cool down coming for the rest of the week. So there's that.

Here's what you need to know for Monday:

  1. HOT. Temperatures are in the 100s.
  2. Did I say hot. Because it is hot.
  3. Is there a four letter word for hot?

What you need to know, currently.

Monday and Tuesday are expected to be the two hottest days in UK history, with temperatures forecast to reach 40 deg C (104 deg F) there for the first time ever.

In a conversation with Currently on Sunday, UK Met Office climate scientist Richard Betts issued a strong warning.

“It's clear that the UK is not ready for such high temperatures,” said Betts. “Transport networks, railways, energy systems, buildings and so on — which have been set up for the climate that used to be — are not ready for the temperatures we're expecting.

”Buildings in the UK tend to be built to keep warm in winter, and only 0.5% of residential homes in the UK have air conditioning. For both days, the UK Met Office has taken the unprecedented step of issuing a Red Warning, the nation’s highest weather alert level — equivalent to a national emergency.

This is the first time the UK Met Office has ever issued a forecast of 40 deg C. The hottest temperature ever recorded in the United Kingdom was 38.7 deg C (101.7 deg F) on July 25th in 2019 at the Cambridge Botanic Gardens.

“There's a 90% chance that record is gonna be broken,” said Betts.
