Widespread rainfall throughout the desert southwest might be as much as 1 inch, however snowfall throughout California, Arizona and Colorado might exceed 1 foot via Monday.

Snow within the desert could sound like an oxymoron, nevertheless it is dependent upon which desert you are referring to as elevation performs a key position and mountain vary peaks differ broadly. The forecast space for the National Weather Service workplace in Las Vegas contains parts of three main US deserts: the Great Basin, Mojave, and Sonoran.

“Elevation is a huge factor for snow in the Western US as elevation varies widely,” mentioned Jenn Varian, a climate service meteorologist in Las Vegas. “Our forecast area has both the highest elevation and the lowest elevation point in the CONUS (continental United States). And they’re in the same county!”

Ice can also be within the forecast and will probably accumulate as much as 1 / 4 inch throughout a number of states. For now, the best confidence in ice exists from Topeka, Kansas to Philadelphia.

Even although it’s January, many Midwestern cities have with snowfall deficits this winter.

Both Grand Rapids and Marquette, Michigan, are about 30 inches beneath regular for the season. Oddly, some Southern cities have truly seen extra snow than ones within the Northeast.

On the southern facet of that very same system pushing via the Midwest, moisture pulled up from the Gulf of Mexico will create situations for average to heavy rainfall to develop. This might result in an elevated menace for extreme rainfall and flash flooding situations, particularly for the southern Plains and the Ohio and Mississippi River valleys.

From Oklahoma via Kentucky, rainfall totals of 1-Three inches are anticipated with remoted greater quantities.
