Sometimes it Snows in April


Only once in my life had I seen an April snow. I was a child, there was thunder, and in a brief but hearty spurt of winter, giant flakes accelerated toward the ground. It wasn't magical, it was eerie.

Now, living in Minnesota, I can fully connect with the metaphor written into the Prince song I listened to as a teenager in New York. Here's why...



The arrival of the robins, first week of April.



Sunday, the southerly winds introduce warm air to cold ground; fog their conversation.



It was spring. The sap told it.


Fresh mushrooms and garlic mustard told it.



The chorus frogs playing their combs told it.



So pleasant it was, combative crows and hawks sat together in harmony.



But, then, it wasn't.



Day one filled out with about eight inches of heavy, wet, snow.



Day two, today, has been wind blown snow, ice pellets tink-tink-tinking the windows, and quickly arising thunderstorms. Not as much snow as last year's three day, April blizzard, but just as disappointing.

April, sometimes.

There was several minutes, at various points of the day, when the skies turned distinctly darker, distinctly yellow. This phenomenon, you may have seen it, can be seen when thunderstorms pass overhead, particularly in winter. So the color of the snow, in those moments, seemed a reflection of the sky, until I noticed the different coloration, blue-white, on the leeward side of snowy features -the steps, the roof fall...

The fire ring. Like a blurred image of a moon crater taken from an earth telescope, the snow took on the contours of the rocks beneath and then sculpted, softly, by wind and shaded in relief by red-beige particles blowing northward across the land. The color was everywhere, and the limits of my imagination concocted that it was created by wind-driven ice pellets scouring the trees. But I was skeptical, this felt familiar -that I had experienced this before -so I asked the Internet.

Consider that the uncovered soils of the Mexico, Texas and New Mexico -in this season, their windy season (I lived in the Chihuahua Desert for three years; experienced the wind and the grit in my teeth), can be drawn all the way up to Minnesota by a powerful low pressure. What happens down there, then, also happens up here -their soils are now our soils.



Eastern Pheobe snowstorm
The Eastern Phoebe, an early spring arrival to our house and woods. We often have to chase its nest building off of doorways and gutters, and this year is no different. Our plan is to build a nesting site for this couple, but haven't quite gotten there yet. The blizzard has been a frustration for the bird, as much as us, as they mix a mud-like substance with twigs and dried grass to attach the nest to metal or wood, and these items are not available due to the new snow cover. Yet another way April can bring trouble to the arriving birds. The phoebes flew into our glass windows several times in the blizzard, looking confused, looking for a place out of the snow and wind.



Today, Friday, it continues to snow. I cannot clear the driveway as the gravel is soft from a complete defrosting, and the blower clogs immediately with the heavy, cement-like snow. I will move on to building raised beds for folks now that the wind has died down and I'm comfortable in the metal shed that sits beneath the soft-wooded, often hollow, basswood that rises 70 feet above it.

Osiris Rising



Winter began at the end of January. The low temperature, early Wednesday morning, January 30, bottomed at -34℉ with a high temperture of -16℉. In February, temperatures did not get very much above 10℉, and were often below zero.



My wife described these low temperatures in this way -one feels surrounded. Imagine you stepped outside of your plane on a flight across country...




When it's minus thirty you can play around with making clouds with boiling water.




I retreated to Cedar Creek Ecosystem Science Reserve one last time to work on some writing. The moon rose, and later that night, the second of several significant snowfalls began.




The snow piles higher; sliding off roofs, snow blown, and accumulation.



The icicles grow longest on the upper floors -some over six feet long.



Ice dams form where house heat melts roof snow, where the weight of snow compresses it at the edges of a roof.



By February 20th we had the snowiest February on record -with still more snow to come. By the same date, however, one begins to think of what else may come -warmth! With it comes melting, wet snows, even rain. The weight on the roof is probably okay under the cold regime, but snow is like a sponge -lighter when dry and heavier when wet. Ordinarily welcome, the warmth could become a problem.



It is easy to imagine the return of glacial lake Agassiz, forming as rainfall accumulates between a snow pack of thirty inches, four foot snow mounds, and the frozen ground. I begin to clear areas previously left untouched -in front of the greenhouse, the sidewalk between the house and front yard and six feet beyond the walkway between the house and the backyard.




I even cleared a path to the compost pile -you can almost make it out on the far right, above. This was to keep us from trudging knee deep to dump the bucket, but also to give the melt water a place to travel down slope, away from the house.




Then it was time for the inevitable: clearing the roof. Wind helped keep some edges below sixteen inches, but other spots were above eighteen inches. This view is akin to a core sample -each storm depositing more snow, compressing under the weight of the next. The upper portion is the thickest and lightest, the bottom crispy and snow-cone like.





One of my better purchases: insulated rubber boots: good to -20℉.




When climbing out a window into a thirty inch snow drift, mind the space above your head. This icicle was disturbed by my head, broke, and dropped on my noggin -not a good way to start shoveling snow off of the roof.




On March 10 we woke up to another six or seven inches of snow. This time the temperature was in the mid to high twenties and the snow sticky: aka wet snow -a sign of things to come.




A six foot tall azalea has little positive things to say about six inches of wet snow. We have noticed that between -30℉ and 30℉, the azalea leaves change form. Warmer temperatures show leaves that are open wide and flat. At colder temperatures, the leaves are tightly rolled.




By Tuesday, March 12, the air was a warm and dewy 37℉. That's when the rain started to fall. By Wednesday, we had a morning fog with near white out conditions. It continued to rain through Thursday -leading to flood reports across several Midwestern States. 

There is little moderation in the Midwestern climate -at times, we can span 70 degrees in a couple of days. On the coasts, even within a three week period, to experience below zero temperatures at the beginning and sixty degrees Fahrenheit at its end, is unheard of. With over thirty inches of snow on still frozen ground across the entire state, days of rain, and the increasing temperature to near 60℉ by Saturday, we will see large scale flooding.




Like Osiris rising from the dead, so too is spring. The geese were heard flying over just a few days ago. The birds, winter friendly, are spring noisy. The popping of basswood, Tilia americana, trunks were heard echoing among the woods on a sunny afternoon of twenty-five degrees -calling us out to tap sugar maples for sap.



From winter weather to spring in bird song.
