I normally don’t allow “Winter Weather Advisories” (WWA) to post on the City page (home page), because too often those end with unremarkable snow totals here. Also, people tune out after a certain point if they are constantly barraged with alerts, which can happen during the winter here. When you see an alert posted on our main page, you can generally place confidence in its importance and relevance to the city. Note that the detailed forecast will always specify accumulating precipitation within the next couple days regardless of alert status.
When I saw the Winter Weather Advisory hoisted on Friday (1/17/20), I decided to post it. I could see that just the front-end of the incoming storm was forecast to deliver 4-7″ in about 12 hours. I could also see that conditions were right for a decent amount of lake effect over the following 24 hours. The $64,000 question, as always, was “how much?”

I have swapped out the somewhat simplistic cloud icons that previously served as a background for navigation links with hand-drawn clouds. My wife and I both feel these new icons provide more visual appeal & warmth. Then again we like anything that reminds us of a mid-century movie poster.
I’m aware that using pictures for links is considered passe by most designers now. So-called skeumorphic interface design was popularized in early Apple products decades ago. Round about 2012 everything started going “flat”.
As for this web app, we have crowned function king. The design is largely fit to purpose with a few embellishments here & there.
Did I mention I’m not a “designer”? Oh well, add that to the list of my faults.
The cloud images were acquired from Iconfinder & appear courtesy of a Creative Commons license. The artist is “Azuresol”. I removed some snowflakes under them since I wanted to use them year-round. I also created a variant that is lighter. A darker icon indicates the current page while a lighter icon links to other pages.
You may have seen the widely circulated story that the local National Weather Service office has measured over 200 inches of snow this season as of Monday morning, February 25th. Unfortunately, some articles have explicitly assigned the total to Marquette. Others have allowed readers to conclude that this is a representative total for the area. In fact, the NWS office is located well outside of the city limits in the highlands which receive substantially more snow.
A helpful rule of thumb is that for every 100 ft you gain in elevation, you can expect 10 additional inches of yearly snowfall.* Of course, there are other factors, such as differing lake exposure, that come into play in the wider area. For this comparison, however, elevation is the key difference. So, given that the NWS office is 800 ft higher than the lakeshore of Marquette, that represents approximately 80″ of additional snowfall per year. In fact, that’s very close to the 30 year normals. Marquette normally receives close to 120″, and Negaunee Township gets a little over 200″ per year.
So far this season (October 1 – February 25) in Marquette, the city’s official NOAA COOP weather station has recorded 96.3″. That’s less than HALF the amount the NWS office received. Just a mile away from the COOP station at our location, 3 blocks south of downtown, we recorded 108″ in that period. We are about 100 ft higher than the COOP station, which explains why we’ve had a bit more snow. To be more than fair, I would allow for an additional foot or so lost to high winds this winter at our station (which would give us about 120″).
So, in other words, both Marquette and Negaunee Twp have received something close to their normal seasonal totals thru the end of February. That would be the proper way to frame a story if, indeed, you were writing about Marquette.

I wrote about this yesterday on Twitter. Given the limitations of that platform, however, I couldn’t really go deep. Let’s dive in.
Here are two screenshots taken within 60 seconds yesterday afternoon:

Would forecasts improve if we removed all the buildings, ripped out all the concrete and moved everyone to tents situated along Lakeshore Blvd? Short answer: likely.
Too often the forecasted high temperatures for Marquette run well below the measured high temperatures, especially on sunny days when the wind isn’t blowing off the lake. This is true of all forecast agencies I’ve observed to one degree or another. It just so happens the local National Weather Service, our forecast provider, is also guilty of this trend.
