I doubt many people will be interested in this, but perhaps some will be. Anyway Western siberia is going to see a northerly blast next tuesday which will bring a bout of very unseasonable weather lasting from tuesday to at least thursday. The following shows the area affected by the cold weather:

Places in that region, particularly the north are likely to see: subzero temperatures especially by night, potentially heavy lying and drifting snowfall, and strong winds. For early August weather like this in this part of the world is very unusual, although it wouldn't look far out of place by the end of the month. 

Surely this is rare in most of September too? I know there can be snow cover in October, I think every October it does. Either way I'm sure the Nenet people who live there will keep warm with their fur clothes if it snows next week 

Edit > just looked at Norilsk's climate in that shaded zone and they have an average August high of 15C, 7C in September then a big drop to -6C as a high in October!

Average high in January -24C

Good report -  thanks

Nice to know winter is not far away 

You can actually briefly see the -10C 850hpa isotherm appear!

I'd expect to see some record temps appear in any weather stations nearby.
