Same here. Max rainfall rate today has been roughly 8mm/hr. Nothing compared to Sept 29th though. I had a rate around 20mm/h with that storm.

5-6c with the westerly winds. Once they shift NWly, temps will drop like a rock under -10c in just a few hours.

Lethbridge is known for its insane temp shifts in a short duration. Chinooks are very pronounced there. It's Canada's second windiest city. :wave:

I noticed your weather station had stopped reporting today and wondered if it was power related. I assume if you have it on a UPS, it just ran out?

Getting warnings about a risk of strong thunderstorms tonight around 9-10PM.......
Wondering where that comes from? Would that be the front moving through?

Snow showers on Christmas Eve morning. Temps are marginal near the water, but looks promising for areas inland with some elevation.
