August 2022 Forecasts and Discussions

It really does. Some moisture rolls in from the south.

S or SSE flow aloft could help pull the storms into the lowlands instead of the usual terrain based stuff to our east.

Mostly sunny here now. That front was a complete miss here. Suns out buns out kinda day

A few stray showers after the main event and I am now standing at 12.7 mm total.

That's pretty impressive. Only picked up about 7 mm here (manual gauge says 6.8 mm). Unfortunately, not enough to make much impact considering how dry the western valley was in July (5.1 mm officially at YXX). Hope to pick up a few stray showers before it dries out again.

Wow. That’s unusual. Shawnigan lake had 32.4mm in July which is above normal for the month. Typically it’s drier over here in the summer.

There was northwesterly flow last night. That let showers sail down the Strait of Georgia until they hit land where the City of Vancouver juts out into it. Then since land has higher friction than water, things pile up, causing lift and enhancing precipitation. You could see it on radar as light precip turned moderate about as soon as it hit land. Meanwhile, out in the valley, you got downsloping off the Coast Mountains and suppression of precip.

Rained all the way from Little Fort to Williams Lake yesterday. More rain today

NW systems sliding in over an arctic airmass always produce the best snowfalls for Metro Vancouver too, in comparison with the valley and especially the island.

14.5mm total in northeast Coquitlam last evening into this morning. Wet!

During those you can get “sea effect” from the much warmer salt water juicing things up and enhancing precip even more.

Late last December one of our snow events featured NW flow. Vancouver got 20+ cm that night while the Valley struggled to get 10 cm.

Most significant NW flow snowstorm around these parts that people probably remember was February 14-15th, 1990.

Textbook YVR special. 33.6cm.

Interesting!

Interesting find. By no means will we ever know the intensity but my guess would be an EF3 at a minimum based on the terrain scaring.

The cool/rainy summer fans on the forum would've loved the rainstorm in July 1972.
Possibly the greatest summer rainstorm ever recorded on the south coast?

Observations from YXX (date: high/low/precip)
Jul 8th: 17.8c/11.1c/23.9mm
Jul 9th: 15.6c/10.0c/19.6mm
Jul 10th: 17.8c/6.7c/7.4mm
Jul 11th: 16.1c/11.7c/21.1mm
Jul 12th: 16.7c/13.9c/70.1mm
Total precip over the five days: 142.1mm

After July 13th, other than 0.3mm on the 18th and 0.8mm on the 20th, it remained bone dry for over a month, until August 16th.

I remember that! I had the best of the enhancement, with 26.5 cm, including 7.5 cm between 4 and 5 AM alone.

Abbs to Chilliwack was uniform for precip last night. It was also one of the dampest chillest August nights in ages. Driving home from work this morning @ 6a.m..and it was dreary drizzling and fall like still abit dark as well now.

I sure do Told, l had recieved my rain guage from DOT that June before it was E.C. and begun volunteering rainfall reports for Kitsilano/Point Grey, that was my first heavy rainfall to record in July of all things. I can't recall the amount but it was impressive.

Really? You were just finishing up grade 6. You must've been smarter than a 5th grader.
