Powerful Storm Will Bring Heavy Rain, Blizzard Conditions Through Friday

A powerful winter/spring storm will impact much of our region over the next several days. Across most of South Dakota and large portions of Minnesota and Nebraska heavy snowfall amounts of 12 to 20 or more inches will combine with wind gusts of 40 to 50 mph to create whiteout blizzard conditions. In Sioux Falls and locations south and east of Sioux Falls, there will be heavy rain today, tonight and tomorrow with lesser amounts of snow and blowing snow late tomorrow, tomorrow night into Friday.

Snow has already started across much of central and northern South Dakota. Snow will continue today with wind increasing throughout the day. Heavy snow with strong wind gusts of 40 to 50 mph will be likely later today, tonight and tomorrow into Friday morning. Travel conditions will deteriorate very quickly across much of central and northern South Dakota throughout the day. A Blizzard Warning is in effect for much of central South Dakota from this morning through Friday morning. Further east, along and east of the James River, a Blizzard Warning will go into effect early this evening and continue through Friday morning.

For Sioux Falls and points to the south and east, today will be mostly rain with intermittent periods of freezing rain, sleet and snow. Rain will continue tonight with periods of freezing rain, sleet and snow toward morning. Tomorrow will start with a mix of rain, freezing rain and snow. Precipitation will change to all snow tomorrow afternoon with snow continuing tomorrow night into Friday. Sioux Falls could get 2 to 4 inches of wet, slushy snow by late tomorrow afternoon with additional snow accumulation Thursday night into Friday.

This is an extremely dangerous winter storm, especially for locations north and west of Sioux Falls that will get heavy snow and strong wind. Heavy snow and whiteout blizzard conditions will make travel impossible from later today, through tomorrow into Friday. Stay tuned for the very latest updates.

Mild With Scattered Showers This Weekend… Flood Threat Continues

It is going to be another sunny, mild day. A weak cold front passed through overnight and that will knock today’s high temperature down a couple of degrees from our 55 degree high yesterday, but temps will still reach the upper 40s to low 50s this afternoon. It will be cooler with highs in the low to mid 40s across Central and Northern South Dakota where we still have a significant amount of snow on the ground.

Saturday will start with some sunshine, but clouds will increase during the afternoon as a storm system moves out of the Rocky Mountains and onto the plains. While whis system will primarily impact areas well to our south, Saturday night, Sunday and early Monday will be cloudy with scattered showers. A few places could get a little light snow or freezing drizzle as temperatures drop into the low 30s late Sunday night into Monday morning. Overall precipitation should be relatively light, around one-tenth of an inch, maybe up to two-tenths in a few spots. Despite the clouds and showers, the weekend will be mild. High temps will reach the mid 50s on Saturday, cooling to the low 50s on Sunday. Cooler air behind the system will drop highs into the low 40s by Monday. Of course, temperatures will be considerably cooler – in the 40s – across Central and Northern South Dakota where there is still snow on the ground.

After Monday, temperatures will warm considerably. High temps will be back in the 50s Tuesday. Sioux Falls amd locations along and south of I-90 could soar into the mid to upper 60s by Wednesday. Even parts of Northern South Dakota could reach the low 50s by the middle of next week.

We continue to closely monitor the flooding situation. Many points along the southern Big Sioux River, the southern James River, the Redwood River, and most other rivers and creeks will continue to rise through the weekend and into early next week. Many are at or will soon be at major flood stage with a few at near record levels. While many rivers are expected to crest this weekend or early next week, additional crests expected next week as more snow melts. For the latest flood warnings go to KSFY.com or check out our KSFY Weather App. We will continue to monitor the flooding and will bring you updates as the situation develops.

A Dry, Warmer Week Ahead

The week ahead is going to be dry and considerably warmer. Afternoon high temps will reach the 40s in most places almost every day this week with some places climbing into the 50s by the weekend.

Today will be partly to mostly cloudy with high temps ranging from the low 40s along and south of I-90 to the mid to upper 30s across Central and Northern South Dakota. Temperatures will be a bit cooler where there is still a considerable amount of snow on the ground.

A weak system will slide across the region late tonight into tomorrow morning bringing scattered light snow showers to parts of Central and Northern South Dakota. Clouds associated with this system will hang around for most of the day tomorrow, but temperatures will be fairly similar to today.

The rest of the week will be sunny with gradually warming temperatures. High temps will reach the mid 40s on Wednesday and gradually climb into the low 50s by Friday. Once again, places with snow on the ground will remain slightly cooler. Obviously that trend will change when the snow melts.

The upcoming weekend will be mostly cloudy with scattered showers, but it will also be mild. High temps will reach the low to mid 50s on Saturday and Sunday. While I think the precipitation this weekend will come mostly in the form of rain, there could be some snow in places where morning temperatures drop into the low 30s.
