We have our first sub-freezing highs in the forecast, -2C on Saturday and -1C on Sunday.
That's rather uncommon to have this early in the month, typically it wouldn't happen until the last week or into November, and on the rare occasion that it does happen they tend to be like -0.2C or something like that. A full -2C high on October 17th is certainly a rarity. After that it seems to go back up to highs in the 0C to 3C range.
No snow on in the forecast yet. Mostly clear and sunny during this cold snap, so that's nice at least.

Today finally ended possibly the longest sunless period I've ever experienced here. We had more than a week of overcast skies and on-and-off drizzle with a little heavy rain and thunderstorms mixed in. Also one of the coolest periods I can remember -- and looking at what little data is available online, last week was freakishly cold for October. DMK airport had a high of barely 26 C (plus an epic diurnal!) on Tuesday:  |

Parts of Southern Saskatchewan are potentially getting 5 to 10 cm of snow tomorrow, thankfully none of that for Saskatoon, just mostly clear skies and dry cold out here.

A lot colder today, high was only 54 (12 c). It was sunny though, pretty great fall day.
Tonight will likely see the first freeze since September 9th, forecast lows are in the high 20s.
Today was also the 34th straight dry day. Can’t say I’m missing the rain at all...

Today, the forecast high was 27C. Instead, we got this  Oh dear, I'm not gonhna attack the BOM though, because those poor down syndrome work experience kids are just learning. They were born , it's not their fault. They didn't ask to be born as degenerates, so I have no right to speak ill of them.  |

Umeå had its first freeze of the season last night. Very late first freeze. Uni station reached -0.2'C.
Airport station reached -2.8'C. among the 155 stations available on Ogimet, only 8 were colder. Of these 8, 6 were 150-1100m ASL and above 65.8°N.
Two however, were all the way down at 56-57°N. Hultsfred airporty down at 57.3°N got down to -3.1'C. Only Vidsel, Tarfala, Tjåkaape and Latnivaara were colder, all of which are 8-11 degrees further north.

You're right. I should have specified the urban parts of the city. Forgot that obviously not everyone is aware of my post about the airport recording a frost a month ago. But the temperature that a station records is not the same as the temperature that all of the area that's closest in distance to that station experiences. The amount of people experiencing a freeze prior to yesterday, at 2m above the ground within 10m of their house in Umeå city was probably less than 1% of the population. |

I made a map of where I expect an official station would've recorded a <0.0'C temperature before last night. Red is most likely, yellow is uncertain. As you can see, very few of these places are actually near houses. ![]()  Depending on the local topography, lots of places in the unmarked parts of the surrounding forests will probably have recorded frosts as well. Probably not within the actual forests themselves, but in many places without canopy where the terrain isn't elevated, air frosts probably occurred. One problem with stations in the Nordics is that stations should preferably be placed on a field without trees or other structures nearby, with as much flat terrain as possible nearby. And the problem with this is that because of the ice age glacier recession and the general properties of bedrock withering, is that the places with fine soil and lots of nutrients, suited for agricultural fields, are going to be the low lying areas that were ocean and lake floors a couple thousand years ago. Meaning any field is very likely to be in a natural depression, and anywhere that's not in a depression is most likely to be forest (or urban). (A few thousand years ago, Umeå was over 200m below the sea) |

Meh, it's the same the World over. Weather stations are often located within airport facilities, so not anywhere near houses and on flat terrain. Nothing specifically Scandi here.

Yup, I mentioned it in a post Wednesday. There’s mandatory evacuations just 5 miles to the west. The sky was bright orange in Boulder today yet just haze here despite the fire being so close. It’s now the largest fire ever in Colorado, pretty cool to say I “experienced” it. There’s 0 chance I have to evacuate, the absolute worst case scenario is it circles around the reservoir and burns the far western neighborhoods. There’s nothing to burn in the developed area so it would die quickly. So for now it’s just cool. It dropped to 26.7 f (-3.0 c) this morning, the first hard freeze this season. Warmed up to 60 (15 c) though this afternoon. |

We had an hourly reading of -12.6C at 7:00am this morning, the actual low for the day is probably a bit colder than that. The daily record low is -14.4C so we came pretty close.
Tonight we have a forecast low of -12C, and then the next three days all have sub-freezing highs as well (-3C, -3C, and -2C respectively). Still no sign of real snow on the horizon, just a chance of flurries one day near the end of the forecast.

At 7:20 PM it had fallen to 49 (9 c) like a normal evening.
Then the wind picked up and the temp suddenly rose. An hour later, it was up to 65 (18 c), a full 16 f warmer.
It peaked at 67 (19 c) around 9 PM and has held steady in the mid 60s since.

Yesterday's official low was -13.3C, just 1.1C warmer than the daily record low.
The forecast has changed a bit and now we only have one day this coming week with a high above freezing. Looks like November came early this year.

Got down to 48F this morning then maxed out at 74F this afternoon with dewpoint mostly in the 40's. Humidity looks to be rising this evening (dewpoint up to 56F now) with southeasterly flow coming in. Tonight's forecast low is 58F.
Next week looks warm, humid, and fairly stable with temps in the 80's/60's and a few chances of precip.

finally some rain; wet Tuesday and moderate steady rain yesterday from 11 am to sometime in the middle of the night  with actual rain numbers; put the map without numbers not in the spoiler since the numbers block the map Amherst got 1.92" of rain from Friday's rain, 1.63" rain on Tuesday (Amherst is about 20 miles to the south of me, possible I got a bit less. there was a strong north-south gradient with the rain; it started on Monday in places further south. I remember it being rainless and cloudy on Monday here; rain 60 miles to the south and sunshine 60 miles to the north in Vermont where I went hiking). Amherst is already above the monthly average; Orange 20 miles to the north not quite there but definitely not a dry month. |

Looks like November came early this year. Geez, we haven't gotten that cold since January 2018. Obviously you're a lot colder than me, but sometimes I'm shocked at how stark the difference is. |
