Light snow showers possible tonight, big warm up on the way this week

An Alberta Clipper System is making its way through the central United States today, producing snow showers as far south as Tennessee, North Alabama and North Georgia.

Futurecast radar shows the clipper moving through Tennessee on its way to North Georgia, including Metro Atlanta, later this evening.

For Metro Atlanta, the snow showers will move into the region after 4pm before tapering off around midnight.

An Alberta Clipper system is a fast-moving low pressure system that develops in Alberta, Canada, and quickly moves through the United States. They “clip” through the United States within 24 to 48 hours, bringing a reinforcing blast of freezing cold air and sometimes nuisance precipitation.

Usually, an Alberta Clipper system moves through the Great Lakes region on its way to the Northeast, but there are times where the Clipper will move further south into the Central US and eventually into the Southeast.

Alberta Clipper Systems are usually very cold and very dry, though they are able to tap into residual moisture in the region it moves through, allowing for light snow showers or wintry mix to form. Not much precipitation falls from clipper systems, but it may be enough to cause nuisance impacts, including slick roadways.

For Metro Atlanta, I am not anticipating much more than a dusting of light, powdery snow on the lawns and vehicles late tonight into early Tuesday morning. A touch more snowfall may be possible in the North Georgia Mountains (no more than an inch), but little to no impacts expected even for the Mountain regions.

And good news for those who prefer warmer temperatures! Daytime highs will climb into the upper 50s to low 60s heading into the weekend.
