64F and Heavy Rain

So much for going to the farmer's market this morning

It's a nice day, here: 21C, sunny with a light breeze.

I was curious to see how our normal temperatures are changing. Meteorologically speaking, an normal value is the average value over a set 30 year period, usually starting with year one of a decade, like 1941-1970. The two international airports in my general vicinity are both in rural areas and close to water, so there will be little, if any, effect from urban heat islands.

In 2013, Environment Canada no longer took observations from Canadian airports. The weather observations were taken by Nav Canada. Rather than trying to merge data from stations at the same location but with different climate numbers, I just took the last period to be 9 years long.
This is what I found...

Well, the bad air from wildfires made it over to us here in Northern Virginia. Looking fairly hazy outside,although certainly not as bad as NYC. Decided I'll move my air purifier downstairs during the day while this lasts.

I saw the Phillies game got postponed because of air. Randi, you're in Pittsburgh, right? How is the air in your area?

Yes, I'm in Pittsburgh.
The weather site says the air quality here is poor.
However, I do not see any haze or notice any problems.

That's good then!

I remember the first year I came to California, on a Sunday I was indoors from midmorning to late afternoon. When I finally looked out the whole sky had a otherworldly orange glow and haze. I had never seen anything like it.

60°F here at 0940
The building heating came on briefly

1700 Pouring rain!

Got up to a 1.4c (app temp 0.4c) morning, sun will rise in 3/4 hr.
Expecting 17c

What a change to come back from my UK holiday.
I had two slight drizzle days (in 3 weeks) and the rest I was wearing shorts and short sleeves and still perspiring.

1900 7.4c felt like 6.5c
Midnight 3.6c felt like 2.1c
0700 0.8c feels like -1.1c

Hoping for 17c today.
I think I should go back to the UK where it was warmer.

One of my friends was doing research on thunderstorms. He spent seven years in South Africa during their summers, and in Ontario during their summers. He was very happy to have seven years with no winters.

Normal summer service for the weather in the UK has been resumed.

Apart from about 10 mins of drizzle last Sunday there had been no rain for weeks here until this morning (and more forecast for later). Although some of my friends, who live about 10 miles away, had a torrential thunderstorm last Monday that caused some flooding in their town.

Temperatures reached 30C on a couple of days last week, back to a much more pleasant (for me) 22C predicted for today.

Just back from the allotment and only had to water in the greenhouse - bliss!
