Snow, Wind and Even Colder Cold Ahead

Our active weather pattern continues today as another system gets ready to roll out of the Rocky Mountains and onto the plains. A Winter Weather Advisory is in effect for much of the region later today through tomorrow for a widespread 2 to 5 inches of snow that will be followed by strong northwesterly wind gusts of 30 to 40 mph that will create blowing snow and potentially near blizzard conditions late tonight and tomorrow.

Snow has already developed across parts of Western and Central South Dakota this morning and will continue to develop and move east throughout the day. Snow will move into Aberdeen this morning and develop in Sioux Falls sometime this afternoon. Snow will continue late this afternoon, tonight and tomorrow with overall accumulation of about 2 to 5 inches. Northwest wind gusts will increase to between 30 and 40 mph late tonight and continue through much of tomorrow. This will create blowing snow that will reduce visibility significantly at times. It is possible that blizzard conditions will develop in places late tonight and tomorrow. While a Winter Weather Advisory is in effect, the National Weather Service could certainly upgrade to a Blizzard Warning at some point if conditions warrant. Bottom line: Snow and blowing snow will make travel difficult and dangerous late tonight through most of the day tomorrow. Conditions should gradually improve tomorrow night into Friday morning.

After the snow, another bitterly cold Arctic blast will settle in. Temperatures will drop into the single digits late tonight and continue to fall to between 15 and 25 degrees below zero by Friday morning. Friday will be sunny but most places will not get above zero.

Temperatures will warm back above zero this weekend. There will be a little sun on Saturday but another system will bring more light snow on Sunday. Even more light snow is possible Monday into Tuesday of next week.

A Cold, Snowy Week Ahead

I hope you had a chance to get out and enjoy the mild temperatures over the weekend, because the warm air is long gone and it won’t be back for quite a while. The week ahead will be bitterly cold with several chances of light snow.

First and most importantly be very careful on your way to work and school this morning. Freezing rain overnight has covered roads and surfaces with a layer of ice. It is extremely slippery this morning, especially on untreated surfaces.

Today will be partly cloudy, breezy and much colder. High temps will only reach the single digits either side of zero with the wind chill factor hovering in the 15 to 30 below range. A Wind Chill Advisory is in effect for much of the region today into tonight.

An active weather pattern will bring several chances of light snow this week. Light snow will develop late tonight and continue through most of the day tomorrow. About 1 or 2 inches of accumulation will be possible. Another system will bring more light snow on Wednesday and yet another system will bring more light snow on Thursday.

In addition to the light snow, each of these systems will also bring down more cold, Arctic air. By Thursday and Friday, low temperatures will drop back in the 15 to 25 below zero range with highs hovering in the single digits either side of zero.

Temperatures will warm slightly by the weekend with another chance of light snow by Sunday into Monday.

WINTER STORM: Heavy Snow Today, 5-10″ Possible

A powerful winter storm system will bring 5 to 10 inches of snow to much of our region today into tonight. Snow developed across Western South Dakota last evening and has been moving east throughout the night. Moderate to heavy snow will continue through most of the day and into this evening, ending from northwest to southeast tonight. 20 to 25 mph wind gusts could create areas of blowing snow this afternoon and evening. Travel conditions will gradually improve late tonight into Saturday morning.

A Winter Storm Warning is in effect for much of Central and Eastern South Dakota, southern Minnesota and Northwestern Iowa through this evening. Sioux Falls, Pierre, Chamberlain, Mitchell, Brookings, Redfield, Huron, Pipestone, Marshall, Redwood Falls, Worthington, Rock Rapids, and Spirit Lake/Okoboji are just a few of the cities included in the warning. The Sioux Falls Area will get about 5 to 7 inches of snow with locally heavier amounts of up to 10 inches possible across the warning area.

A Winter Weather Advisory is in effect for locations north and south of the warning. Aberdeen, Watertown, Winner, Yankton, and Sioux City are some of the cities included in the advisory. Lesser snowfall amounts of about 2 to 5 inches can be expected in the advisory area, however there could be locally heavier amounts.

Temperatures are in the mid teens this morning and will continue to fall throughout the day. Because it is so cold, the snow will be light, fluffy and prone to blowing and drifting. While the wind will not be as strong as it was with our last winter storm, northeasterly wind gusts to between 20 and 25 mph this afternoon and evening will create areas of blowing snow that could reduce visibility at times, especially in rural areas. The wind will decrease to about 5 to 15 mph by late this evening and stay fairly light through the rest of the weekend.

Other than some light snow Saturday night into Sunday morning, the rest of the weekend will be mostly dry and bitterly cold. On Saturday and Sunday high temps will only reach the single digits to teens with morning lows dropping well below zero.

We are watching another potential system that could bring areas of freezing rain and snow Monday into Tuesday. There could be some accumulation with this system. Strong wind and areas of blowing snow could also be an issue. This one is still several days away. Stay tuned, we’ll take a closer look at this one after we get today’s storm out of the way.
