The temperature in Denver officially dropped to 3 degrees above zero early Wednesday morning. It was cold enough to shatter the previous record low for October 30 by 4 degrees. It was our third record temperature in 3 days and one more record is expected Thursday morning.

The records on Monday and Tuesday were related to the daily high temperatures. Denver only reached 21 degrees on Monday and 18 degrees on Tuesday. It had never stayed so cold on these dates in the past so new "record coldest maximum" temperatures were set for October 28 and October 29.

One final record is expected Thursday morning when the combination of clear skies, mainly light winds, and snow on the ground allows temperatures to plunge below zero along the Front Range. If the temperature manages to drop below -2° early Thursday, the all-time record low for October in Denver will be broken. That record was set on October 29, 1917.

Alberta has suffered YET MORE record-breaking low temperatures of late, as brutal Arctic air continues to descend anomalously-far south for the time of year.

The southwest of the Canadian province appears to have fared the worst this week.

According to data from Environment Canada, the mercury in Banff plunged to -23.3C (-9.9F) on Monday morning, which set a new daily low for October 29, eclipsing the previous mark of -22.6C (-8.7F) set back in 1991.

The Bow Valley area saw temperatures sink to -23.2C (-9.8F), low enough to pip the previous all-time record for the date — the -23C (-9.4F) from 2002.

Prime harvesting weather is fading in Iowa, but three-fourths of the state's corn acreage isn't yet harvested.

The latest update from the U-S Department of Agriculture Monday said Iowa's corn harvesting lags 11 days behind the five-year average at this stage of the season.

As of this past weekend, one-third of the state's soybean crop was still in the field. That's about a week behind average.

Gulf Stream is 15% weaker, region south of Greenland coldest in 1,000 years

'We are 50 to 100 years ahead of schedule with the slowdown of this ocean circulation pattern,' says climate scientist Michael Mann.
A stubborn blue spot of cool ocean temperatures stands out like the proverbial sore thumb in a recent NASA image of the warming world - a circle of cool blue on a planet increasingly shaded in hot red.

A region of the North Atlantic south of Greenland has experienced some of its coldest temperatures on record in recent years, a cooling unprecedented in the past thousand years. What explains that anomaly?

Climatologist Michael Mann of Penn State University, in this month's "This is Not Cool" video, explains that this phenomenon may be an indication that the North Atlantic current, part of a larger global ocean circulation, is slowing down.

Comment: A bit more data from Phys.org:
Levke Caesar, a scientist at the Potsdam Institute for Climate Impact Research in Germany and co-author of a study that found the current to be 15% weaker. "When the circulation slows down, we have less heat transport to that region."

Another study, published last year in the journal Nature, found the system to have reached its weakest point in 1,600 years, although it says the loss of strength probably began from natural factors.

Summit County ski areas in Colorado have already received up to 42 inches of October snowfall

The next storm, due early Tuesday, is expected to add another 6-8 inches

If you're peeved because we've just had our third October snowstorm with another one due early Tuesday, maybe this will cheer you up: The three Front Range ski areas that are open have been getting good snow, and they're looking forward to more from this next storm.

Keystone, which opened Oct. 12, has received 40 inches of snow this month, and Breckenridge, which is currently slated to open Nov. 8 but might open early, has received 42 inches, according to a spokeswoman.

"It's hard to believe it's October right now," Keystone/Breckenridge spokeswoman Sara Lococo said Monday morning. "Snow is still falling here in Breckenridge and across Summit County. It's just incredible that it looks like mid-winter conditions. The weather has been great, and the temperatures have been great, so our snowmakers have been out in full force."

Yes, it's meant to almost be summer, less than two months till Christmas! But, as predicted by Snow Report SA on Friday, a flurry of snow has fallen in parts of South Africa overnight and this morning, 28 Oct 2019... with delighted South Africans sharing their photos and video of this fairly rare occurrence, to receive snow so late in the season.

As parts of South Africa are battling heatwaves and drought, the Western Cape has instead been hit by cold fronts over the weekend... and snow has covered mountain peaks from Kaaimansgat, Villiersdorp to Tulbagh, Worcester and the aptly named Sneeukop (Snow Head) outside of Rawsonville.

October's not over, yet 31 inches of snow has already fallen in Great Falls, Montana - Half a typical year's total

More than 16 inches of snow fell at Showdown Ski Area last week.
More than 16 inches of snow fell at Showdown Ski Area last week.
Three to 4 inches of snow, heavy at times, is expected to hit the Great Falls area Monday morning, followed by near record-breaking cold Tuesday and Wednesday, as the fall of 2019 continues to behave more like December or January.

Just four months into the snow year, more than half of a typical year's worth of snow already has been recorded in the city.

Following Monday's new snow, temperatures will plummet to 30 to 35 degrees below the normal.

"Probably timed with the morning commute, so it's going to be a mess," Christian Cassell, a meteorologist with the National Weather Service in Great Falls, said of the latest round of snow forecast Monday morning.

Arapahoe Basin
Colorado's 2019 ski season is gaining ground rapidly after heavy October snowfall.

Arapahoe Basin (pictured top earlier this month), then Keystone (pictured below), were the first resorts in North America to open a fortnight ago and Loveland became the third this weekend.

Two more areas have announced openings in the next week, Wolf Creek, which was the first to open last year, will open on Halloween this Thursday and Eldora this Friday, November 1st, a fortnight ahead of their planned opening date.

All are benefiting from some good early snowfalls which have seen Steamboat, although not yet open, claim it has had record October snowfall already of 1.1 metres (44 inches). A further winter storm is expected in the area over the coming 48 hours.
