If you have outdoor stuff to do, you have about three days before some really big changes make things a little more difficult. It is true… Parts of our region will get snow later this week.

After a very windy weekend, things are going to calm down a bit as we start the week. Today will be mostly sunny with highs in the upper 60s. Central and western South Dakota will climb into the low 70s this afternoon. The wind will hold to about 5 to 15 mph through this afternoon. 

The next couple of days will be mild but breezier. High temps will stay in the upper 60s to low 70s with south wind gusts to between 25 and 35 mph both Tuesday and Wednesday. 

A powerful fall/winter storm system will move into the region late this week into this weekend. Rain, snow and much colder temperatures are likely. Rain and cold will arrive throughout the day Thursday with rain mixing with and changing to snow Thursday night into Friday. It’s still too early to get specific, but some minor snow accumulation is possible in Sioux Falls and places along and west of I-29. More significant snow accumulation is possible along and west of the James River with even higher amounts possible along and west of the Missouri River. Again, it’s too early to get specific, but accumulating snowfall is very possible across central, western and northern South Dakota.  

In addition to the rain and snow, there will be very strong wind gusts and near record cold temperatures. On Friday and Saturday, high temps will only reach the mid to upper 30s with lows dropping into the 20s this weekend. 

Stay tuned for updates on this developing storm. We will have the latest and get more specific with potential snow amounts as we get closer. 

A cold front moving across the plains this morning will bring some pretty big changes to our weather today. After a brief shower or thundershower around daybreak, the rest of today will be sunny, breezy, cooler and a lot less humid. High temps will only reach the mid 70s with northwesterly wind gusts in the 25 to 35 mph range throughout the day. 

The rest of the work week will be mostly sunny and mild with our next chance of rain arriving by the weekend. Saturday and Sunday will be partly to mostly cloudy and cooler with scattered showers and thunderstorms. High temps will drop into the mid to upper 60s this weekend.

TODAY:
Sunny, breezy and cooler. High: 76°. Wind: Northwest 20 to 30 mph.

TONIGHT:
Clear and cool. Low: 48°. Wind: North 5 to 15 mph.

TOMORROW:
Sunny. High: 75°. Wind: South 5 to 15 mph.

It’s hard to believe that Labor Day weekend is almost here! Other than clouds and scattered rain Friday night into Saturday morning, the weekend forecast is looking great for the State Fair or anything else you might have going on outdoors.

Today will be sunny and a bit breezy with high temps in the upper 70s. It won’t be as windy as it was Tuesday, but northwesterly wind gusts of 15 to 25 mph are likely throughout the day.

A couple of relatively weak waves of energy will move across our region tomorrow into Saturday and that’s our only hiccup in the holiday weekend forecast. Friday will start with sunshine, but clouds will gradually increase throughout the afternoon. Scattered showers will develop across central South Dakota by mid to late afternoon Friday and move east to Sioux Falls by Friday evening. Scattered rain is likely Friday night with clouds and showers gradually exiting from west to east on Saturday morning.

While there could be a couple of isolated thundershowers, I do not expect severe weather. Rainfall amounts of one-quarter to one-half inch are possible with the heaviest rain falling along and south of the South Dakota/Nebraska state line.

We will see some sunshine on Saturday afternoon but high temps will only reach the low 70s. We’ll do our best to make up for that on Sunday and Monday with plenty of sunshine and highs in the upper 70s to low 80s.
