Making Up For Hot Days In Early October

The sun peeks out today with upper 30s, still a far cry from our normal high of 51F in the metro. Monday daytime should be dry, but a fairly vigorous Alberta Clipper rotates a pinwheel of slushy snow across the state Monday night into Tuesday morning. Halloween 2023 may start out with a coating to an inch of slush during the morning but possibly dry for Trick or Treating, with wind chills in the teens.

Halloween Extremes & Warming October Nights

Ghosts and ghouls might still haunt the streets for candy, but it seems like Halloween's getting a little cozier rather than spookier! According to a study by Climate Central, it turns out that across the United States, October nights have been getting warmer since 1970. That's right, a whopping 89% of the 244 cities they looked at have felt the heat creeping into their spooky season. It's not just a small change either; the average autumn temperature has risen by almost 3 degrees across the country. Specifically, those eerie October nights have warmed up by about 2.2 degrees on average! And hey, even in Minneapolis, known for its chilly Octobers, the nights have warmed up by a spine-tingling 3.8 degrees since 1970. Seems like the creatures of the night might be trading their capes for lighter clothes as the years go by!

KEY CONCEPTS

  • Fall temperatures have warmed by 2.7°F on average across the U.S. since 1970.
  • Fall warming can extend allergy and wildfire smoke seasons, and disrupt leaf-peeping.
  • Warming trends have also taken the chill out of a fall tradition: trick-or-treating.
  • From 1970 to 2022, October nights have warmed by 2.2°F on average across the U.S.
  • Of 244 U.S. cities analyzed, 216 (89%) have seen October nights warm up since 1970.
  • October nights have warmed by more than 2°F in 153 of the locations analyzed.

Twin Cities Halloween Outlook

Here's a very early Halloween outlook for the Twin Cities on Tuesday evening. Note that temps will hover around 30F with feels like temps in the 20s thanks to breezy NW winds around 15mph.

Halloween Outlook Next Tuesday

The weather outlook for Halloween Tuesday looks quite chilly with readings only warming into the 20s and 30s across the state. This will be quite a bit below average for this time of the year. There will also be areas of snow and possibly minor accumulations for some.

Halloween climatology in the Twin Cities

"Halloween is typically a time of crunchy leaves on the ground, a bit of chill in the air, and lots of candy. High temperatures in the Twin Cities are generally in the 40s and 50s. It is more common for the daily high on Halloween to be in the 60s than in the 30s. 70s tend to be rare, with only eight Halloween high temperatures being 70 degrees or above or about one in eighteen years. The warmest Halloween on record was 83 degrees in 1950, with one of the coldest one year later with a high of 30 in 1951. The coldest Halloween maximum temperature was a bone-chilling 26 degrees back in 1873. The last twenty-five years have had some balmy Halloween afternoons, like the 71-degree F high in 2000. We've had some chilly ones as well, like in 2017, when the temperature never rose above 35 F at MSP. The area has not seen a Halloween washout, with measurable precipitation during the evening, since 1997. Measurable precipitation has occurred on Halloween only 26% of the time in the Twin Cities, or 38 times out of 145 years. The most rain recorded was in 1979 with .78 inches. In 1991 .85 inches of precipitation fell, which was snow. In spite of the 1991 Halloween Blizzard, measurable snow on Halloween is about as rare as getting a full-sized candy bar in your trick-or-treat bag. Since 1872 there's been enough snow to measure only six times: 0.6 in 1884; 0.2 in 1885; 1.4 in 1932; 0.4 in 1954; 0.5 in 1995; and of course 8.2 inches, with the opening round of the Halloween Blizzard in 1991. Thus there has been measurable snow on only 4% of the days."

Making Up For Hot Days In Early October
By Paul Douglas

Recently someone asked me why I put on snow tires when all-wheel drive is "good enough". Last winter the metro picked up 90.3". Third snowiest since 1884. Between October and April we experienced 84 days with at least some snow. On 21 of those days MSP picked up at least one inch. On 7 days 4" or more fell. And we had two separate days of 8"+.

Granted, it was a La Nina winter and an El Nino warm phase in the Pacific Ocean should (in theory) result in a drier, milder winter. But forgive me for not taking any chances.

The sun peeks out today with upper 30s, still a far cry from our normal high of 51F in the metro. Monday daytime should be dry, but a fairly vigorous Alberta Clipper rotates a pinwheel of slushy snow across the state Monday night into Tuesday morning. Halloween 2023 may start out with a coating to an inch of slush during the morning but possibly dry for Trick or Treating, with wind chills in the teens.

I see 40s by late week but 1 week from today more snow may fall. About those snow tires...

Moon Phase for October 29th at Midnight

1.4 Days After Full "Hunters" Moon - Oct. 28 at 3:24 p.m. CDT "With the leaves falling and the deer fattened, it is time to hunt. Since the fields have been reaped, hunters can ride over the stubble, and can more easily see the fox, also other animals that have come out to glean and can be caught for a Thanksgiving banquet after the harvest. A partial lunar eclipse also occurs on this date. Unlike the May event, this one sees the moon brush the Earth's darker umbral shadow; at maximum (20:14 GMT) about 12% of the moon's diameter will be within the shadow, darkening its lower limb. The Earth's Eastern Hemisphere faces the moon when the eclipse takes place, however, Atlantic Canada will see the last of the umbra slip off the moon when it rises and sharp-eyed New Englanders will be able to perceive the faint shading of the penumbra as the moon appears above their horizon."

"Everything We Know About 'Superfog' and How It Caused a 158-Car Pileup in Louisiana"

Wednesday's brutal 158-car pile-up in Manchac, Louisiana, is attributed to a weather phenomenon. Eight people are confirmed dead, and 63 were injured due to the pile-up. The scene from the bridge was like something from a disaster movie, as the charred remains of mangled vehicles betrayed the level of devastation. Shell Shocked Passers-by looked on shell shocked as cars burned, with dozens of motorists trapped in their vehicles. Later that night, Louisiana governor Bel Edwards asked for prayers for the victims amid other blood donation calls, while many asked how such a disastrous pile-up could occur.

"This liquid crystal fabric is 'smart' enough to adapt to the weather"

Have you ever left the house without a jacket on a balmy day, only to regret overestimating your chilly weather tolerance? Instead of dashing back home for your coat, there may come a time in the near future when you simply use an app to control your clothing's level of insulation. Created by researchers at MIT, FibeRobo is a cheap, programmable, shape-changing smart fiber reliant on a liquid crystal elastomer (LCE). Among their many uses, garments imbued with their new LCE fiber could adjust their structure to become more insulated in colder temperatures, and vice versa for warmer weather. With an additional ability to combine with electrically conductive threads, a wearer could directly control their FibeRobo clothing or medical wearables like compression garments via wireless inputs from a controller or smartphone.

"Tips to Conserve Your Energy and Help Prevent Outages During Extreme Weather Events"

"People use more energy during heat waves and winter storms. But high energy demand and compromised supply can lead to outages. Here's what you can do to prevent them and be prepared. Heat waves and winter storms combined with power outages are a dangerous recipe that can have tragic results. Extreme weather-induced power outages mean sweltering under relentless heat or freezing temperatures with no power to operate an air conditioner or heater. Texas, for example, has its own non-profit operated grid called ERCOT, so when much of the state saw its hottest July on record in 2022, officials there issued what's called a conservation appeal asking the public to reduce energy consumption during periods of extreme heat. This came on the heels of a power crisis in 2021 in the same state when a brutal winter storm crippled wind turbines and natural gas infrastructure that weren't adequately winterized. Gas-fueled power plants in Texas went down as a result, leaving millions cold and in the dark."
