Winter Storm Wrap-up (2/21/22 – 2/23/22)

After 50+ hours of snowfall, the sun finally appeared this afternoon!

This was a storm for the record books on parts of the Lake Superior Plateau (Negaunee area) where they received over 37″!

Down closer to the lake, we measured 18.3″ between 8 AM Monday the 21st and 5 PM Wednesday the 23rd. Meanwhile, the city’s official station recorded 13.5″ from 8 AM Monday to 8 AM Wednesday (we only recorded an additional 0.6″ after 7 AM). No daily or monthly records appear to have been set in Marquette.

Yes, “Twosday” (2/22/22) was by far the snowiest day of any February in our 5 years of measuring snow. In fact, that day ties 12/01/2019 for the snowiest one-day total on our record books. However, the December day produced 1.44″ of melted snow. Whereas yesterday the snow only melted down to 0.65″. Much lighter snow this time around! You can thank the colder temps for that — something you might have thought you’d never do.

It appears this was a very elevation-dependent storm system with Big Bay recording 20″ and similar numbers as ours from a station in Harvey close to the lake. Further up in Trowbridge (elevation: ~1000′), we see totals approaching 2 feet. That all makes sense since the lake definitely played a big part in the storm. Lake-effect (or enhanced) snowfall is quite subject to forces of elevation. For reference, we are 100′ higher than the official COOP station in Marquette, which partially explains our higher snowfall totals (generally, in fact).

Not for nothing, the website quadrupled it’s normal traffic on the 23rd! Google really likes our snowfall measurements and weather history pages. Many thanks to our dedicated visitors who encourage us to keep marching out into the wind-driven snow to take those measurements all winter long!

Jan ’21: Warm & Dry & A Somewhat Clear Sky

Marquette just recorded its least snowy January on record (1857 – present)! The official station at the Water Treatment plant recorded a mere 3.5″. Normally, we receive almost 30″.

Melting that snow and combining it with whatever ice and rain also fell, amounted only to 0.77″. That’s less than half the 30 year normal amount of 1.83″.

Also, the mean monthly temperature of 24.7° in January ties for 8th on the list of all time warmest with 1878.

Here at our station near the Jacobetti Home for Veterans, we recorded 10.4″ of snowfall (0.72″ of liquid) in January. Whereas the last 3 winters we averaged 29.4″.

Our station’s monthly mean temperature (as measured from 8 AM to 8 AM and rounded to whole numbers) was 23.9°. That’s +5.5° compared to our station’s normal.

Record Cold in Marquette

Following 2 days of highly unusual lake-effect snow (8″ recorded at our station), Marquette saw it’s coldest October 27th in recorded history. NWS Marquette has confirmed that the low of 20° this morning set at the COOP station near the lakefront broke the old record of 22° set back in 1887.

October is running about 5° below normal. As of the morning of 27th, this is the 19th coldest October on record (since 1857). Finishing in the top 20 certainly appears doable if the forecast holds.

Overall, we’ve had a cool (meteorological) autumn so far as September was also a couple degrees below normal.

We’ll just have to see what the winter brings. It could all turn on a dime next month. But at least the weather’s never boring in the U.P.!

Post Thanksgiving Winter Storm Recap

That was quite the winter storm for the 1st day of December! Three blocks south of downtown, we unofficially recorded a 12.1″ snowfall total. The official city COOP station near the lakefront reported 12.9″. That’s a new daily snowfall record for Marquette, assuming that number is confirmed by the local National Weather Service office. There was one other (unofficial) report in town of 13″.

Turns out, the storm concentrated its efforts further north than originally thought. More of Wisconsin was supposed to be in the mix. So my fears of it moving south and leaving us with another underwhelming snow total, as happened just 4 days beforehand, proved to be, let’s just say, “slightly off target”. Like a dart in the door frame.

Then there was the issue that so-called Winter Storm “Ezekiel” gave us twice the liquid precipitation (what you get when you melt a quantity of snow) than was modeled!

Also, during part of the morning and early afternoon, Lakes Huron and Superior hooked up to make extra snow.

Well, at least we had a beautiful sunny day to dig out!
