Check the Weather More Than You Think You Need to
Okay. This is the lesson where I sound a little obsessive, and I'm fine with that.
I check the weather three times a day when there's a trip on the calendar. Morning, midday, and again right before I load the car. People give me a hard time about it. Faith thinks it's funny how much I care about a forecast. Honestly, I don't think it's excessive at all. Foothill conditions change fast, and the forecast at 6am is not the forecast at noon. That's not me being dramatic, that's just how our weather works up against the mountains.
Here's the thing about the Wasatch foothills specifically. You've got elevation doing stuff to temperature, you've got sun angle changing everything by the hour, and you've got these warm-up and refreeze swings that can turn a trail from packed powder to soup in about ninety minutes. A forecast that says "30s, partly cloudy" doesn't tell you what the snow is actually going to be doing at 11am versus 8am. You have to dig a little deeper than the little phone icon.
What to actually check
Don't just look at the temperature. Look at:
Overnight low and when the sun hits the trailhead. A trail that refroze hard overnight will be firm and easy early, then go slushy once the sun gets on it. Knowing roughly when that switch flips tells you your whole timing plan.
Wind, especially at ridgelines or open saddles. Foothill trails aren't exposed like the high peaks, but you'll hit open stretches where wind matters a lot more than the temperature number suggests. Wind chill is real and it's not just a weather-app gimmick.
New snow in the last 24 to 48 hours. This is the one people skip and it's the one that actually changes your day the most. New snow changes float, changes trail visibility, and changes how deep you're going to sink no matter how good your snowshoes are.
That last one is where I want to tell you about a mistake I made, because it's a good one.
The rental snowshoes that were wrong for the day
I rented a pair of snowshoes once without asking a single question. Just grabbed what the guy handed me, figured a snowshoe's a snowshoe. Headed up a trail that had gotten six or eight inches of fresh snow the night before, on top of already soft stuff underneath.
I was postholing straight through with almost every step. Not fun-crunchy-snow postholing, I mean sinking to the knee, over and over, dragging myself back out each time. I thought I'd just gotten unlucky with the trail. Turns out the snowshoes I'd grabbed were sized way too small for that much fresh, unsettled snow. They didn't have enough surface area to float me on top of it.
That's when it clicked for me: float depends on the snow that day, not just your weight and not just whatever pair is sitting on the rack. Now I actually ask the rental guy questions before I walk out the door. What's the snow been doing the last few days. Is it fresh and soft or packed and old. If I'd checked the weather and known there was a foot of new snow in the past two days, I would've asked for a bigger shoe before I ever got in the car.
So checking the weather isn't just about whether you'll be cold. It changes your gear, your timing, your whole plan for the day.
A simple home routine
You don't need anything fancy for this. Here's what I actually do:
- Check the night before, mainly for the overnight low and any snow coming in.
- Check again the morning of, specifically for wind and whether that snow actually showed up like predicted.
- Check one more time an hour before you leave. Forecasts shift. I've watched a "clear morning" turn into a "light snow starting at 10" between breakfast and boots-on.
If the forecast shows a warm front moving in or temps climbing fast through the morning, that's your cue for an early start. I've gotten burned skipping this step, three checks and everything, saw a warm front, went anyway because I didn't want to get up early enough to beat it. Ended up in slushy afternoon snow that turned the whole trail into mashed potatoes by the time we were heading back. Timing beats distance, every single time, especially with our swings.
One honest limitation on my end, I'm not out here reading avalanche bulletins and terrain reports like a backcountry guy. I stick to groomed and low-angle foothill trails on purpose, and the weather checking I'm teaching you is for that kind of trip. If you want to get into steeper or more remote terrain, that's a real avalanche course, not this class.
Before next time
Pick a day this week and just practice the three-check habit, even if you're not going anywhere. Night before, morning of, hour before you'd leave. See how much the forecast actually moves. It'll make believers out of most of you.
