- Winter Storm Eboni will bring snow and rain to the West through Tuesday.
- The storm will intensify in the Plains and Midwest after Christmas.
- Parts of the Plains and Midwest will see strong winds and significant snow.
- Snow may also affect northern New England late-week.
Winter Storm Eboni will pivot into the Plains and upper Midwest after Christmas, where it will intensify and lay down an expansive swath of wind-driven snow.
This next snowstorm will push through the West Tuesday before it heads across parts of the Plains, upper Midwest and northern New England Wednesday through Friday.
Eboni was named that the expectation that area criteria – winter storm warnings for 400,000 square kilometers or more – would be met later is week.
Rain and snow are currently spreading inland from the California and Oregon coasts as Winter Storm Eboni arrives from the Pacific. Snow and rain are also falling in parts of northern Nevada and southern Idaho.
Winter storm warnings and winter weather advisories have been issued by the National Weather Service from the Sierra Nevada into parts of the Pacific Northwest, Great Basin and Rockies.
Winter storm watches are now in effect in parts of the central Plains for Tuesday night through Thursday where heavy snow and gusty winds may lead to dangerous driving conditions.
Here’s an overview of the forecast in each region, but keep in mind that changes are likely, so be sure to check for updates.
Winter Storm Eboni will move across the Southwest Tuesday and bring rain and mountain snow to parts of the region through Wednesday.
Tuesday-Wednesday (Graphical Forecast)
Plains, Midwest and New England Forecast
Winter Storm Eboni will emerge and strengthen in the central Plains by midweek as an upper-level trough – a southward dip in the jet stream – ejects out of the West.
Temperatures are expected to be cold enough on the northern side of this storm for significant amounts of snow to fall from the northern and central Plains into the upper Midwest and northern Great Lakes region.
Strong winds will accompany this system, which, when combined with the snow, could impact visibility and lead to near-blizzard conditions.
How Much Snow?
At least 6 inches of snow is likely from parts of the central and northern Plains into the upper Midwest and northern Great Lakes. Totals of up to a foot (possibly more) are also possible in areas that experience the heaviest snow.
The trickiest forecast for snowfall totals is for cities along the southern edge of the expected snowfall, which could change from rain to snow. Minneapolis and Sioux Falls, South Dakota are two examples.
Below is an overview of where the heaviest axis of snow could set up based on the latest forecast guidance available. Keep in mind, the area of heaviest snow could shift farther north or south in future forecast updates based on the track of the storm.
While it is too early to talk about exact amounts in New England, it appears that 2-5 inches of snow is likely across most of northern New England.
