The number of fires burning through BC has jumped to 180+, with nearly 2000 firefighters combating them and many thousands displaced. The Red Cross has initiated an appeal for assistance.
Ridging looks to stand mostly firm over the region through the next mid-term, bookended by an upper low in the NE Pacific and a downstream trough through the east.

On the other hand, the GFS is forecasting highs around 13-16 C in S QC at the end of the week, when I’m going camping. 😦

*12Z run. The law of averages should save your bacon and give us some 36-39 C days in return!

I’m still savouring the fact we salvaged 3 dry days in a row here last week. We’re just shy of our July precip average now and it’s only the 9th which is apparently par for the course based on the way things have been going this year. We haven’t managed a below-normal precip month since January.

Respectable setup for a severe weather event for AB/SK today and into tomorrow.
Watches have been in place for AB mentioning the potential for strong storms and possible tornadic activity this afternoon, ahead of heat rebuilding into the medium range.

Those supercells near Edmonton look quite good. There’s no mesoanalysis up there but the shear profiles are quite favourable according to the 21Z RAP. The tornadic potential will be increasing through 9 pm MT when the inversion kicks in.

I only had about 10 mm for July before receiving over 30 mm yesterday.
More rain is expected tonight which should lead to some storms in your area which could be strong. After that, the convective potential shifts to SW ON.

YOW was at 87mm for the month before today which is already precariously close to the July average of 91.9mm.
We’re less than 200mm short of our entire yearly average precip with close to 800mm recorded so far. Plenty of time left to close that gap, needless to say.

Our annual total to-date is also around 800 mm according to the local reporting stations but they had several outages throughout the year and underestimate the liquid equivalents of snowfall events (on March 14-15, the McTavish station recorded under 30 mm of QPF even though I got 78.1 cm at 11:1).
