Warmer than it should be, but still cold
The historic average temperature for Eagle Butte in the second week of January is 23.84°F with a record high of 60°F and a record low of -24°F. Our average daily temperature to this date for January 2021 is 39.95° F with a high of 49°F. Our lowest 2021 temperature to date is 10° F. While this is much warmer than “normal,” it is still heavy coat weather.
Winds will calm a bit this weekend, from the west and south-west, and are likely to hold steady between 8-15 mph with occasional gusting. The extreme low-pressure system that formed in the Bering Sea last week starting to move into the northern Pacific as evidenced in satellite observations. The resulting system is accumulating a massive amount of moisture over an area that stretches across most of the North American coastline from southern California to western Alaska; this massive atmospheric front is literally “pushing” the jet stream north allowing for an atmospheric “river” of warm south-west air to flow across the Great Plaines unabated. This is directly responsible for our unusual winter-warmth.
Expect fast moving clouds, brisk winds, and unseasonable but still cold weather. There is a one in four chance that it will snow/winter-mix through the weekend. Watch for ice. The sunsets this week are likely to be epic.
NOAA updated its Drought Monitor Map for the Western U. S. on December 29th, 2020. We were assessed as “abnormally dry” with potential impacts likely to include stunted grain and pasture growth, dryer topsoil, depleted ground water, and increased risk of fire.
