Monday July 1st… 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 Five

The good news today is that a dying front has put an end, at least temporarily, to the heat wave in the Midwest. The bad news is that this same boundary didn’t have enough steam to end the current steamy regime in the Northeast. Usually fronts any time of the year once they get through the Great Lakes area don’t stall and move through the Megalopolis area, bringing relief there. Not so in this situation, which is perhaps a sign of climate change. Here are advisories up as of this morning:

Elsewhere the only other major concern, heat wise, are wildfires in the West. The worst blaze has made national news in northern California northwest of Sacramento, which is the Yolo County conflagration, that has burned over 50 square miles of territory and threatened about 100 structures.

On Tuesday while remaining hot, some slightly cooler air will filter into the Northeast. In most instances the southern tier of states will see above average temperatures that will resemble those of today. Heat will be building again in the north and central Plains:

Nee York City will see a few more days of dangerous heat:

90°+ temperatures again today with the combination of heat & humidity making it feel closer to 100-105° in some places. Excessive heat warnings in effect for NE NJ and the Lower Hudson Valley, Heat Advisories away from the coast. Full briefing available:

107 degrees: The heat index in Washington at 1p (air temp 94, dew point 76). This is the highest of the summer so far, and it could still go higher today. More info:
10:07 AM – 2 Jul 2018
After the 4th holiday heat will be shifting west:

Very dangerous heat wave with elevated to potentially critical fire weather conditions later this week into the weekend. Peak of the heat wave expected Fri/Sat when many triple digit record highs are expected for inland areas.
As usual, I’ll add more relevant items to this post during the day as they cross my radar.

From the 1st:
Keene, New Hampshire reached 102F today. At 6 pm EDT, they were 100F with a very steamy 77F dewpoint. By comparison, the Laredo Airport reached 104F with low 60’s Dewpoint. When I check at midnight, I expect our National Weather Service thermometer reached ~103F.
