It's not like it's never snowed here in April before. But after a number of 20-degree days (or warmer), we're simply not having it. As we looked up at the sky and cursed the heavens, asking, "Why the f*** is this happening?" we decided it would be more productive to ask actual experts the same question.
Why is it snowing when we've been seeing temperatures above 20 degrees lately?
Dr. Djordje Romanic, a professor of atmospheric sciences at McGill University, gave us an explanation from a scientific perspective.
Basically, it's all because of "a mid-latitude cyclone" in the northeast United States so you can blame New Hampshire and Massachusetts.
As the cyclone spins counterclockwise, it's lifting warm and moist air from the western Atlantic above dry and cold polar air from the north.
"It happened that the temperature profile in these two air masses is just the right [one] to form snow instead of rain," he said.
Can we chalk it up to global warming?
Dr. Romanic told us it's "not scientific" to say a particular event is due to global warming. Rather, we'd have to look at the frequency and severity of those types of events over time.
"We can never say that 'this or that particular event is caused by global warming.' Why not? Because we cannot go back some 200 years, undo all CO2 emissions, and see if we will have snow on 21 April 2021," he said.
How does this snowfall fit into Montreal's weather history?
Dr. Romanic said that on May 9, 1983, there was a snowfall of around 5 cm in Montreal and that on April 1, 1993, there was a snowfall of around 28 cm.
"It is not extreme in terms of it never happened before. On the other hand, such weather conditions are very unlikely and can be considered as an anomaly that is not observed on the yearly basis," Dr. Romanic said.
According to Paul Walker, senior meteorologist for AccuWeather, "April is often a month of big weather swings."
He said it's "not unheard of" to have high temperatures around 16 C to 20 C followed by a cold turn, leading to some snow several or a few days later.
Based on the 30-year average of Montreal weather, he said it typically snows 3.2 days in April with an average of 5.1 inches or 13 inches falling during the whole month.
"The season's last snowfall typically happens in April," he said.
What are the chances of it snowing in May?
Walker said a late snowfall happens in May about once in a decade.
While we've been enjoying unseasonably glorious weather in Montreal, true Montrealers have been holding their breath, knowing from experience that good weather can change on a dime — especially in April.
As much as we were hoping winter was completely behind us, there is a chance that it could snow a little in Montreal next week. Ugh.
Before you get too upset, one forecast is predicting snow on Thursday while some others are not so it's definitely not a sure thing.
According to the Weather Channel — which services Apple's weather app and Google weather searches — there's a 60% chance of precipitation, which includes both rain and snow on the morning of April 22. The Weather Network also advises a chance of snow on Thursday but anticipates accumulations of less than a centimetre. Environment Canada hasn't called for snow at this point.*
The good news? Even if the Weather Channel is right, the snow won't last long. Snow showers would become rain showers by Thursday afternoon and the next day is expected to reach a high of 15 C.

Just like you, we're fiending to go outside in our Nikes and a denim jacket — and while this year's season is drastically different from what we're used to, we've rounded up things all Montrealers do when the warm weather hits for some sense of normalcy.
Shove our winter gear to the back of our closets in defiance
We get it — Quebec winters are tough.
If you're from Montreal, you may be used to aggressively shoving your heavy-duty winter coat, hats, boots, gloves, scarves and other assorted paraphernalia to the back of the closet the minute Montreal weather hits plus five.
Spend more time outdoors
This one is a no-brainer. While Montreal's many winter activities can be fun, nothing beats being able to ride your bike — or a BIXI — through part of the city's 500-kilometres of bike paths or sunbathe in one of the city's many green spaces.
Since spring is basically the start of the summer for Quebecers, it's the perfect time to start planning regional road trips across Quebec.
Hit up the city's many cultural centres
While it may not yet be warm enough to sprawl out on the grass of your favourite Montreal park, it's just warm enough to spend the day comfortably strolling around the city, hitting up the latest in exhibitions at local museums — which are open in Quebec red zones.
Shop downtown on weekends
Montreal malls are often a go-to for winter hangouts, being indoors. But when spring hits and you want to enjoy sunny days while they last, browsing through downtown shops is the perfect weekend activity — followed by an affogato or tacos to go.
Buy artisanal snacks from Atwater or Jean-Talon Market so we can drink outside
If you love trying local delicacies and supporting local businesses, Montreal's two major markets are chock-full of handmade snacks and cider for the perfect foodie weekend in the city.
Since you need to also have food to be able to drink in public in Montreal, local eats are the perfect pairing to cheap SAQ wine.
Head to the gym for our summer gains
Hear us out on this one. We know Montrealers have been positively itching for gyms to reopen in Quebec red zones. As of March 26, Montrealers everywhere will be able to flock to gyms, giving them something else to do other than Netflix-ing life away during the seemingly endless COVID-19 pandemic.
