Friday July 6th… Dear Diary. The main purpose of this ongoing post will be to track United States extreme or record temperatures related to climate change. Any reports I see of ETs will be listed below the main topic of the day. I’ll refer to extreme or record temperatures as ETs (not extraterrestrials)😊. Here is today’s main climate change post related hot topic:
Historic U.S. Heatwave Day Nine
Today it’s the West’s turn to see historic heat. Los Angeles may see their warmest day in recorded history, which we’ll definitely keep tabs on. If we see all-time record heat in L.A. this will obviously be big news. To start let’s review how hot it got across the country on Thursday:
The only heat of note occurred in New England and in the Southwest Thursday. A front is putting the kibosh on the heat wave, which lasted a full week, in the Northeast, today. By Saturday our western heat wave will be peaking in the Southwest while 90s return to the western Plains:
There is some good news here. Look how pleasant Northeast maxes should be over the weekend.
A couple of weeks ago models were forecasting our heat dome to peak near Colorado at about 600 decameters. How did that forecast turn out? Very well, actually. The thing officially maxed at 600 or 601 decameters over Colorado at 06Z FRI, but won’t be a U.S. 500 millibar height record:
Here is the panel I presented Wednesday 6/27/18 for comparison, :
This panel was an outlier forecasting 500 millibar heights to be about 20 decameters higher than model ensembles, but even so, a remarkably good forecast around my 240 hour out “garbage” threshold. Every year that I have been a professional meteorologist since 1983 met models have improved, but I have yet to see perfection.
We officially have a 600 dm ridge per the sounding at Grand Junction at 12z; this ridge will be responsible for record heat in California today
Extremely critical Red Flag fire weather conditions today into Saturday across portions of SW California due to widespread record breaking triple digit heat, gusty north winds, and widespread single digit humidities.

@fly_BUR is the hottest ever recorded in the area since records began in December 1939! #heatwave
There’s, um, quite a few of them
#LAHeatwave #ValleyFire: Based on current conditions, @sbcountysheriff has ordered MANDATORY EVACUATIONS for the entire community of #ForestFalls. Evac center information will be released as it becomes available. Those in the affected area are asked to leave. #ReadySetGo ^eas

#LAHeatwave . It is so hot that the wind literally burns in the shade. This weather feels supernatural. Expect only slight relief tomorrow, highs 100° – 108°.

In Yerevan, Armenia, on Monday, temperatures soared to 42 deg C, a record high for July and tying its record for any month.
It’s still ungodly hot where I’m at in florida but i can’t find anything more recent than this about it. When will this heat wave pass?
As usual, Florida will remain hot through August. Climate change is probably responsible for adding a few degrees to hot temps across most of Florida during the summer since the 1970s and 1980s.
Keep up the superb piece of work, I read few blog posts on this internet site and I believe that your site is real interesting and has got sets of
