A dangerous – I’ll even call it historic – winter storm will sweep across the region today, tonight and tomorrow bringing over a foot of snow and wind gusts to between 40 and 50 mph. A Blizzard Warning is in effect for most of South Dakota and large portions of Minnesota, Iowa and Nebraska through tomorrow and into tomorrow night. White-out blizzard conditions are likely across central, western and northern South Dakota today with snow developing in Sioux Falls and across eastern South Dakota, southwestern Minnesota and northwestern Iowa this evening.

I think we’ve finally found where spring has been hiding. Warmer temperatures are on the way and this time the mild weather will stick around for more than just a day. Of course, the way things have been going this spring, you won’t be surprised when I tell you that we are watching another winter storm system that could impact much of the region this weekend.

Today will be mostly sunny with high temps ranging from around 50 degrees in Sioux Falls to the mid 40s in the north to the low 60s across south central South Dakota. Today’s high temperature will depend largely on how much snow you still have on the ground. The more snow you have, the cooler today’s high temperature will be.

The mild air will stick around through the rest of the week. Tomorrow and Thursday will be mostly cloudy, but high temps will still warm into the mid to upper 50s.

A powerful storm system will blast into the region on Friday and stick around into the weekend. Friday will still be mild, but there will be rain and scattered thunderstorms possible throughout the day. As colder air works its way into the system late Friday night, rain will change to snow. Heavy snow and strong wind will be possible Saturday and Saturday night. It’s too early to get specific with accumulation amounts, but most places will get some accumulation some places could get significant snow accumulation. In addition to rain and snow, there could also be some freezing rain.

This system is still several days away. We will get more specific with the storm track, precipitation type and amount as we get closer. In the meantime, expect that there will likely be weather related travel issues from late Friday through Saturday and into Sunday.

Make plans for some outdoor time today, because this is the last mild day we are going to have for quite a while. The sun will shine this morning, but a cold front will bring clouds and maybe even an isolated shower or two this afternoon. Despite the clouds and the possibility of a shower, high temps will still warm into the upper 40s to low 50s today.

After today, temperatures will drop well below average and stay there through the weekend and into next week. High temps will only reach the low to mid 40s tomorrow and Friday. On Saturday, high temps will drop into the upper 20s to low 30s. On Easter Sunday morning, you’ll wake up the temperatures in the single digits to low teens with highs only reaching the mid 30s on Easter afternoon.

In addition to the cold, we do have a couple chances of rain and/or snow as we head into the weekend. Areas of light snow will be possible tomorrow night and early Friday morning, with a chance of rain, freezing rain and snow late Friday night into Saturday morning. Easter Sunday will be mostly dry with a slight chance of an isolated rain or snow showers late Sunday into Sunday night.

After another stretch of well below average high temperatures, we are finally going to warm things up. High temps will reach the upper 40s today, low to mid 50s tomorrow. Unfortunately, once again we’ll only manage to hold on to the mild air for a couple of days before plunging back to temperatures that are more typical of early to mid February.  

Clouds will linger across parts of eastern South Dakota, western Iowa and Minnesota early this morning, but they’ll blow out of here rather quickly. Today will be mostly sunny with high temps reaching the mid to upper 40s in Sioux Falls and in locations east of the James River. Much of central South Dakota will warm into the 50s today. Tomorrow will be even warmer with highs reaching the low to mid 50s.

By late tomorrow into tomorrow night, a cold front will blast across the Northern Plains, bringing colder air that will stick around through the rest of the week, the weekend and beyond. High temps will only reach the 40s on Thursday and Friday with colder 30s (and not just 30s… low to mid 30s) on Saturday and Easter Sunday. In addition to the cold, areas of light snow – mixed with rain at times – will be possible on Friday, Saturday and Sunday.

As of right now, long-range models are suggesting temperatures will remain below average through most of next week. Keep your fingers crossed and hope for a change, I’ll let you know how things go.

We are watching a powerful winter/spring storm system that will impact much of our region today, tonight and tomorrow. Areas of rain will develop today and then mix with and eventually change to snow tonight. Most places will get mostly rain, however parts of northeastern South Dakota and much of Minnesota could get heavy snow later today, tonight into tomorrow morning.

There will be plenty of moisture with the system. Most places will get one-half inch to an inch of liquid precipitation over the next couple of days. Unfortunately in some places that precip will come in the form of snow. A Winter Weather Advisory is in effect for Aberdeen, Watertown, Brookings, Pipestone, Worthington and the Lake Okoboji area. A Winter Storm Warning is in effect for areas east of that line and include Sisseton, Milbank, Clear Lake, Marshall, Redwood Falls, Windom and Jackson. Warnings and advisories will go into effect later this morning across northeastern South Dakota, this afternoon across parts of Minnesota. Check our WEATHER ALERTS page for details on your area.

Stay tuned for updates, there could still be changes to this forecast depending on the temperature profile and when and if rain changes to snow in some of these locations.
