Here’s When The First Accumulating Snow Of The Season Typically Arrives

With that in thoughts, we have researched National Weather Service 30-year common information (1991-2020) to seek out the date by which the season’s first measurable snow – outlined as 0.1 inch or extra – sometimes happens to compile the map under.

Keep in thoughts, these are averages of the season’s first snow. Any given season can produce the season’s first snowfall both very early or very late, relying on the climate sample on the time.

C​hicago is one such current instance because it noticed its first measurable snow on Nov. 15 this 12 months, however waited till Dec. 28 final 12 months.

Much of the Midwest and Northeast see their first measurable snow of the season in November or December.

The month of October normally ushers within the first measurable snow from the Rockies to the Northern Plains and northern Great Lakes.

The South would not see accumulating snow yearly, however on common, January and February are probably the most favored months for at the very least a coating of snow.

H​ere’s a more in-depth have a look at what’s typical for every area, together with the particular common first snow date for a number of cities.

Northeast

October is often the month’s first snow within the mountains of northern New England and the Adirondacks.

Most of the remainder of the inside Northeast joins in throughout November, whereas the Interstate 95 hall from New York City to Virginia sometimes waits till December to see its first accumulating snowfall of the season.

Midwest

The season’s first snow within the Midwest sometimes happens in October alongside the northern tier of states, from northern Michigan to the western Dakotas.

In November, a lot of the Ohio Valley, the remainder of the Great Lakes, the mid-Mississippi Valley and the Central Plains be part of the ranks.

W​est

Snow can fall over the very best peaks of the Rockies even in summer season.

September snow is taken into account common from the upper elevations of western Montana into the Colorado Rockies.

Otherwise, October sometimes heralds the arrival of the season’s first flakes in decrease elevations of Montana, Wyoming, the Wasatch, Colorado’s foothills and mountain valleys, and the mountains of northern New Mexico.

November first snow is typical from the plains of southeast Colorado into the remainder of northern New Mexico, northeast Arizona (Flagstaff), parts of the Great Basin and the inside Northwest.

The menace of snow isn’t normally a consider locations like Seattle and Portland, Oregon, till late December.

South

Yes, components of the South do sometimes see snow, however not essentially yearly.

The Texas Panhandle and the very best elevations of the southern Appalachians are exceptions. Those areas can anticipate their first snow in November or December.

Valley places of the southern Appalachians, components of northern and Middle Tennessee, northern Arkansas, central and japanese Oklahoma will see their first dusting of snow someday in December, if in any respect.

For extra southern places, akin to Atlanta and Dallas, as a substitute of mentioning a mean first date of measurable snow, we specify a mean timeframe throughout which you’ll be able to anticipate the “best chance” of measurable snow annually, outlined by the typical first and final dates of measurable snow. This is often in January and February from the Carolinas to north Texas.
