Here it happens without fail. Sometimes the wind will start at 0C and other times at -5C, but it will always arrive. It usually stops an hour or so after sunrise.
It is exactly like that! Can you explain why that happens?
In other countries the temp drops and drops and here even with 17 hours of darkness it only drops like 6c. We only get really really cold if there is a very deep covering of snow.

Either from downslope winds -the cold air on the mountains "falls" down hill, or a land breeze, when the warmer air of the sea rises and is replaced by colder air from the land. While both involve colder air, the turbulence breaks up the existing pools of settled cold air.
Your scenario sounds different to here. The temp would drop a lot more than 6C if there were 17 hours of darkness here. Your winters are quite cloudy and it might just be the insulating effect from that. Also, the less sunshine received during the day, the less potential for radiative cooling.
Current temps.. Winds gusting from the West up to 30mph.
Pretty simple why we're warming.. arrows indicate winds at the 5000' level. Pretty much drawing warm air up from the south, ridge building up and so temps at that level are warm (notice no blues/pinks anymore) and also notice whats happening..
South winds are pushing up the appalacians and down the slope into the east. Otherwise West and WNW winds don't necessarily mean warm temps. but because the warm air is being pushed north, and then east is the reason why we're warming up even with those West winds.
Winter storm warning for Minneapolis! Looks like a mix of freezing rain changing to snow. Accumulations could be up to 6 inches in the Twin Cities area. We had a band of rain today, but I think the brunt of the storm is coming tomorrow and Thursday morning
They're still forecasting 50-80mm of rain and 15-20cm snow here over the next few days... Although from the radar maps the really heavy precipitation will be just North (at least for tonight). We'll see what happens but I'm glad we have smaller rivers with deeper valleys than Manitoba. :P
I wonder what the weather will be like in the Sudbury area in a couple weeks. I'm going on a geology field trip there in end of April/early May.

Probably not. Sometimes those glaring anomalies show up and unless it's a radiational cooling night it's usually due to instrument error.
Meanwhile, some of you should remember what I said last year about severe thunderstorms at colder temperatures meaning that at some point severe thunderstorms will occur when it's snowing. During the great New England Blizzard in February severe thunderstorm damage from thundersnow was reported in Long Island, and now at last we have the culmination of this phenomenon. In Nebraska right now there are two thunderstorm-related alerts, one a significant weather advisory and one an actual severe thunderstorm warning . In and of itself it isn't unusual this time of year, but what is unusual is that they are occurring in the midst of wintry precipitation, and in subfreezing air. It's not just a subfreezing thunderstorm (which these days is not uncommon in winter storms), but it's a damaging thunderstorm. Here are the current conditions out of Sargent, Nebraska:
This is the first time I can recall a Winter Weather Advisory and a Significant Weather Advisory being in effect simultaneously. Surely this 20F significant weather advisory sets a new record for the coldest thunderstorm alert ever issued.
Meanwhile, we have an actual Severe Thunderstorm Warning occurring in the midst of freezing rain and snow. Likewise, I'm pretty sure a Severe Thunderstorm Warning has never been issued before when it's 29F.
And below is what a subfreezing severe thunderstorm warning looks like :
This is the first time I've ever seen or heard of a severe thunderstorm warning mentioning "rapid accumulation of ice". Quarter-sized hail and freezing rain occurring simultaneously is going to be an awesome and terrifying experience for weather enthusiasts who are in the area.
Below is the significant weather advisory. Half-inch sized hail occurring when it's 20F is also going to be awesome and terrifying:
Below is a current radar showing the thunderstorm alerts in the pink zone (meaning mixed precip, sleet, or ice). The one to the west is the significant weather alert and the one to the east is the severe thunderstorm warning:
