Third Winter Storm Already This Month to Hit Mid-South This Weekend

The rumors have been flying for days. And some of them are true!

Another winter storm is taking aim on the Mid-South and Southeast this weekend.

For some, this will be the third winter wallop in two weeks after many wondered if winter would ever come.

Winter had been missing for much of the eastern two-thirds of the nation prior to the start of the new year. However, back-to-back winter storms have since swept through the same areas targeted by this weekend's event.

Forecast models have converged on two swaths of significant wintry precipitation arcing from the Midwest to the Southeast. I've listed them below, along with details on where I see the most noteworthy amounts occurring.

ALL SNOW: Minnesota to Missouri Friday & Saturday

The storm will start like a classic Alberta Clipper system, diving quickly to the south through the eastern Dakotas and Minnesota to Missouri.

Generally speaking, a 24-hour window of light to moderate snow will leave most areas with 2 to 6 inches, but higher amounts of 4 to 8 inches are possible roughly 100 miles either side of a line from Sioux Falls, SD to Kirksville, MO.

SNOW, SOME ICE: Arkansas to Carolinas Sunday

The storm will be strengthening as it dives into the Mid-South Saturday night, pulling in more moisture from the Gulf of Mexico.

Confidence is much lower on amounts and location of the heaviest bands as the storm goes through this transition. This will likely result in gaps in heavier snowfall totals across portions of Missouri and Arkansas. The highest totals in these states, potentially up to six inches, will likely occur in the higher terrain of the Ozarks on either side of the state line.

Forecast map on more specific amounts across Mid-South will be available when confidence is high enough to be credible.

Snowfall rates will pick up quickly as the storm matures through the Tennessee Valley Sunday. This is also when a mixture of freezing rain and sleet will overspread northeast Georgia and the Upstate regions of South and North Carolina. North and west of where ice accumulations occur, a swath of 4 to 8 inches of snow is becoming increasingly likely. A consensus of the most reliable forecast data places this 100 miles either side of a line from just east of Memphis to Knoxville in Tennessee, then across the Appalachians from northeast Georgia to Pennsylvania.

Lighter amounts of wintry precipitation will also fall outside of the aforementioned areas, but with lesser confidence in how much. Dry air will lead to a sharp cutoff in snowfall amounts on the northern side of the storm track, whereas the timing of a changeover from rain to frozen precipitation will affect amounts on the southern side.
