But what, exactly, is a blizzard? A blizzard doesn't always mean "a lot of snow," though it can certainly bring heavy snowfalls, as this storm is expected to along parts of the East Coast. Rather, the National Weather Service defines it as a snowstorm with winds regularly above 35 miles per hour and "considerable falling" or blowing snow for at least three hours.
A bomb cyclone produced freezing temperatures across a large portion of the US from the Gulf coast to New England, bringing heavy snow to North Carolina where two were killed in storm-related conditions, and setting records in Florida, where officials warned of ice and falling iguanas. About 150 million people were under cold weather advisories and extreme cold warnings in the eastern portion of the US,
Burlington just reached a whopping 73 days with snow on the ground, the longest stretch since 2004. Burlington is reporting 71 inches as of February 24, which would be average snowfall for the entire winter, and they still have over a month left of the snow season. The city has accumulated more snow than, Denver, Anchorage, Boston, Providence and Minneapolis.
From late Saturday night through Sunday, guidance is converging on timing and warmer snow levels but diverging on intensity and ridge-top wind magnitude, with the most consistent signal for light snowfall in the northern and central ranges and limited coverage farther south. Most mountains should stay in the low single digits for accumulation during this first push, with favored terrain near the Continental Divide able to approach around 4 inches by Sunday evening.
To get back to average snowpack, we essentially need to have the most snow that we've ever had for the last 30 years between now and mid-April. It would be extremely difficult for Colorado to get back to a normal/average snowpack. As an example, when looking at the Independence Pass SNOTEL site in central Colorado outside of Aspen, we typically have 13 inches of snow-water-equivalent at the end of February. This year, we only have 6.7 inches of SWE.
Records that are likely to never be broken again were set on Mount Washington, such as a 98 inch storm total, and 49 inches of snow in a singular day on February 25. This same season, the Mount Washington Observatory measured a total of 566 inches of snow, a record that still stands to this day.
Many of us are riding the high of the recent major snowstorm wondering when the next big powder day will swing through. Unfortunately for most of North America, it looks like the snowy weather won't be returning anytime soon, or at least not for the next week. Meteorologist Chris Tomer 's Mountain Weather Update paints a rather sad picture for snowfall totals in North America between January 29th and February 5th.
The midweek stretch looks like the most reliable window for fresh turns, with the steadiest snow lining up Wednesday night into Thursday and lighter add-ons into Friday. Snow levels run a little high early, then step down late week, so snow quality should improve as the storm cycle matures. Some areas could see the next wave begin as early as Sun night (02/15), but confidence drops quickly with lead time and placement.
