As winter grips the nation with its frosty fingers, snow enthusiasts and researchers can prepare for a flurry of activity, especially in the mountainous regions. Over the past 24 hours, the snowfall totals have been significant, with the Nohrsc Burnt Mtn in Montana taking the lead with an impressive 22 inches of new snow, adding to its already substantial 24-inch base. Close behind, Placer Basin, also in Montana, reported 19 inches of fresh powder atop its 66-inch base, promising excellent conditions for winter sports aficionados.

Montana isn't the only state basking in the powdery glory; Utah's Black Flat-U.M. Ck has seen 17 inches of new snow, adding to its impressive 170-inch snow base, offering pristine conditions for skiers and snowboarders alike. Meanwhile, Wyoming's Nohrsc Townsend Creek Snotel and Blackhall Mtn are dealing with heavy snow and blustery conditions, receiving 11 and 10 inches of fresh snow, respectively, ensuring a winter wonderland for the adventurous at heart.

Looking ahead, the snow forecasts for the next 24-48 hours suggest that the snow will continue to pile up, particularly in Alaska where Esther Island and Exit Glacier are expecting 22 and 18 inches of new snow, respectively. Colorado's snow forecasts are also promising, with Weminuche Creek and Echo Lake anticipating 15 and 14 inches of snow that should contribute to a growing base and excellent powder conditions. While Michigan and Wisconsin are facing a mix of snow showers and foggy conditions, with locales like Big Bay 9Sw and Land O Lakes expecting up to 14 inches of new snowfall.

This bountiful snowfall signifies not only a transformation of the landscape into a winter paradise but also heralds good news for ski-resorts across the affected regions. From the Rockies to the wilds of Alaska, the heavy snowfall ensures an extended season of winter sports, tourism, and research opportunities. Cities near these high snowfall areas, while not directly impacted by such vast totals, may see increased visitation and economic benefit as snow seekers head towards the mountains. So, strap on your boots, grab your gear, and head to the slopes for some of the best snow conditions of the season.

Oceanic Niño Index (ONI) - La Nina Cooling Phase

The Oceanic Niño Index (ONI) is a rolling 3-month average temperature anomaly, and used for tracking El Niño-Southern Oscillation climate patterns. Based on the latest data for the last 3 months (JFM), the Oceanic Nino Index is currently -0.39, signifying a La Nina period. A persistent above average sea surface temperature may signify an El Niño episode. Conversely, a below average sea surface temperature will signal the onset of La Nina occurences.
