Farmers Almanac First Snowfall Map: When Will It Snow First?

Two almanacs, two forecasts

The name causes confusion because there are two long-running publications. The Old Farmer’s Almanac, founded in 1792 and based in Dublin, New Hampshire, is the older of the two. The Farmers’ Almanac, first published in 1818 and based in Maine, is a separate publication that has issued its own forecasts under the pen name Caleb Weatherbee. Searches for a Farmers Almanac first snowfall map often mix the two, so check which publication a map or article is quoting.

Both almanacs have long divided the country into regions and described the expected weather for each in broad terms, such as a cold, snowy stretch in a given week or a milder-than-normal month. Their winter outlooks have traditionally been released months in advance, typically in late summer.

How almanac forecasts are made

Almanac methods are not fully disclosed. The Old Farmer’s Almanac describes a formula that traces back to its founder and draws on solar activity, weather patterns, and climatology. The Farmers’ Almanac has described a long-standing formula that considers factors such as sunspots, the positions of the planets, and the tidal action of the moon. Neither method is used by the National Weather Service or by mainstream meteorological research, and both almanacs report high accuracy rates that independent reviews have generally not been able to confirm. Keep that in mind when a Farmers Almanac first snowfall map circulates online each fall.

Almanacs and weather folklore

Almanacs and weather folklore often travel together. Sayings about thick corn husks, heavy coats on animals, or the color bands on woolly bear caterpillars have been passed down for generations as signs of a hard winter or an early first snow. They are part of the charm of the season, but scientists have not found that any of them reliably predicts winter weather.

What a Farmers Almanac first snowfall map can tell you

Read as an outlook, an almanac map can suggest whether a region is expected to have an early or late start to winter and whether the season leans cold or mild. That makes it a fun conversation starter and a useful reminder to winterize the car, find the snow brush, and check the furnace before the cold arrives. What it cannot do is name the date and place of your first measurable snowfall with any reliability. The first snow often comes from a single storm, and a storm’s track and temperature profile can be forecast only days ahead.

It also helps to separate the almanac’s prediction from the map’s design. A colorful regional map can look precise even when the underlying forecast is a short phrase applied to a large area. Treat any Farmers Almanac first snowfall map as entertainment and general guidance, not as a schedule.

When the first snow usually falls: the climate record

For a reliable baseline, look at climatology: the long-term record of when the first measurable snow, at least 0.1 inch, has fallen at each weather station. NOAA’s climate data make it possible to map the typical date of first snowfall across the country, and many National Weather Service offices publish first-snow statistics for their local cities. Compare any Farmers Almanac first snowfall map with this record before you plan around it. Typical patterns look like this:

• High elevations of the Rockies and other western mountains can see snow as early as September, and the highest peaks occasionally in late summer.
• The northern Plains, the Upper Midwest, and northern New England often see their first measurable snow in October or November.
• The central Plains, the lower Midwest, and the Ohio Valley often wait until November or December.
• The mid-Atlantic coastal plain, including the Interstate 95 cities from Washington, D.C., to New York City, often waits until December or later.
• Much of the Southeast, the Gulf Coast, Florida, and the desert Southwest can go one or more winters without measurable snow.

These dates vary widely from year to year. A city whose first snow usually arrives in mid-November might see it in October one year and after New Year’s Day the next. Some National Weather Service offices also list the first one-inch snowfall, because a light coating often comes weeks before snow that covers roads.

Why first-snow dates differ within a single state

Elevation and geography can split a state into very different first-snow seasons. In Colorado, the high mountains are often white weeks before Denver. In New York, the Adirondacks and the Tug Hill Plateau usually see snow long before New York City. In Washington, the Cascades can be snowy by fall while Seattle often sees little snow at all. Plan around the snow season of the place you are driving through, not just your home city.

Combining the almanac, the climate record, and the forecast

The most useful approach treats each source for what it is. Start with the climate record to learn when first snow is normal for your area. Glance at the almanac or a Farmers Almanac first snowfall map for a seasonal storyline, keeping its limits in mind. Check NOAA’s seasonal outlook for official probabilities of a colder or wetter season. Then rely on National Weather Service forecasts in the final week, when the timing and amount of the first snow can actually be predicted. If you are planning an event or a trip around early snow, the climate record tells you the risk, and the forecast tells you the timing.

Preparing for the first snow on the road

The first snowfall of the season often causes more trouble than later, heavier storms. Drivers are out of practice, road crews may be treating roads for the first time that season, and slush on warm pavement can refreeze quickly after sunset. Bridges and overpasses ice up first. No Farmers Almanac first snowfall map can tell you which morning that will happen, so prepare early.

Get your vehicle ready before the forecast turns: check tire tread and pressure, replace worn wiper blades, top up winter washer fluid, and test the battery. Keep an ice scraper, gloves, a blanket, and a phone charger in the car. When the first snow arrives, slow down, increase your following distance, brake gently, and give snowplows plenty of room.
