How to Actually Read a Morning Snow Report

The board says fourteen inches. The parking lot says something else. Learning to read a morning snow report is the difference between chasing a storm that already peaked and standing at the base of Corda Bowl when the rope drops on genuinely fresh snow.

A snow report is a compressed instrument panel. Every resort publishes the same handful of numbers, and each one answers a specific question. Read them in the right order and you can call your morning before the coffee is gone.

The Ticker, Column by Column

Here is a typical Mount Vireo line the way it scrolls across the base-area board:

24H 14" · 48H 22" · BASE 62" · LIFTS 12/14 · TRAILS 142/154 · SURFACE PP

Six fields, six answers:

• 24H — 14": new snow in the last 24 hours. This is the number that decides whether you set an alarm.
• 48H — 22": the two-day total. Compare it to 24H to see the shape of the storm. If 48H is barely more than 24H, the snow is fresh and still stacking. If 48H is roughly double 24H, the storm is winding down and yesterday was the deeper day.
• BASE — 62": settled snowpack depth. A coverage and safety number, not an excitement number. It tells you rocks are buried, not that today skis well.
• LIFTS — 12/14: lifts spinning versus total. A gap almost always means something: wind hold up top, avalanche control still running, or terrain that has not opened for the season yet.
• TRAILS — 142/154: open runs versus total. Read it alongside the grooming report, not on its own.
• SURFACE — PP: the code for what is actually under your bases. More on codes below.

Why 24-Hour Beats Base Depth

New skiers fixate on base depth because it is the biggest number on the board. It is also the least useful one for planning a single morning.

Base is cumulative and settled. A 62-inch base with 0" in the 24H column skis like whatever the mountain was three days ago — wind-buffed, tracked out, or bulletproof, depending on the weather since. A 62-inch base with 14" overnight skis like a powder day. Same base, completely different morning. The variable that changed your day is the 24H figure and the wind, not the base.

Eleven inches overnight. Meetings moved. That is the number you act on.

Surface Codes, Translated

The two-letter surface code is where most people get lost. The common ones:

• POW — powder. Rare on the board itself; usually you infer it from a big 24H number.
• PP — packed powder. Powder that has been skied and compressed into a firm, predictable, edge-holding surface. The everyday good-day code.
• MG — machine groomed. Corduroy. Tilled overnight into ribbed, fast, forgiving snow.
• PP/MG — a mix, typical mid-storm or mid-week.
• Variable — honest code for "it changes by aspect and elevation." Sun-baked one side, chalky the other.
• HP / FG — hard pack and frozen granular. The polite way of saying East-Coast firm. Bring a sharp 1 and 3 edge tune.
• Corn — spring code. Frozen overnight, softening in the sun. Timing is everything; too early is boilerplate, too late is mashed potatoes.

If you see a report that reads FG with 24H at zero after an overnight refreeze, that is a death-cookie morning. Sleep the extra hour or sharpen your edges the night before.

Read the Timing, Not Just the Number

The number tells you how much. The timestamp tells you whether it is still yours.

Snow that fell overnight is baked into the report and shared with everyone who reads it. Snow that is still falling through the morning is quietly restocking the mountain while the crowd thins out. Check when the report was posted and check the current radar. A storm that clears at 6 a.m. gets tracked out fast. A storm that keeps dumping through 11 a.m. refreshes your lines all morning.

Grooming has a clock too. Groomed at 4 a.m., tracked out by 9:40. Do the math on how many corduroy laps that actually buys you, and plan your first-chair routine around it.

The Grooming Report Is a Separate Document

Most resorts publish a nightly grooming list next to the snow report, and it is the most under-read page on the site. Cross-reference it every morning.

On a groomer day, the runs listed as groomed are your fast laps — head for Corduroy Boulevard before the ridges get scraped flat. On a powder morning you want the exact opposite: the runs they left alone. Anything not on the grooming list held its fresh snow overnight. That is where The White Room is hiding.

Put It Together: A Morning Call

Say the Vireo board reads 24H 11" · SURFACE POW and the grooming report leaves Cookie Alley and the Corda Bowl gates untouched. That is an alarm-clock morning: dry boots the night before, be in the maze early, and point it at the ungroomed steeps while the snow is still soft.

Now flip it. 24H 0" · SURFACE FG, clear and cold, upper mountain on a wind hold showing LIFTS 10/14. That is a sharp-edges-and-patience day — carve the groomers that got tilled and skip the scoured ridgelines entirely.

Either way, the read starts the night before, in the cold and dark of the parking lot. Stuff a few hand warmers in your gloves before the drive up, start the morning in a merino 250 base layer, and put your feet in a proper over-the-calf ski sock instead of the cotton tube you found in the dryer. The report tells you where to point; your kit decides whether you last until last chair.

The Bottom Line

Read the report in this order: 24H and wind first, surface code second, grooming list third, base depth last. The biggest number on the board is the least important one for planning your morning, and the two-letter code nobody explains is where the whole day is decided.
