Rain & Snow Today… A Warm, Sunny Weekend AheaD

The rain, freezing rain and snow has ended in most places. Everything is still wet though, and with temperatures hanging around the freezing mark, there will be slippery roads and sidewalks this morning. Take your time and be careful.

Today will be cloudy and cool with highs in the mid to upper 30s. Thanksgiving day will be cloudy and slightly warmer with a chance of light rain and snow in the afternoon and evening. We could get a little (less than a half inch) sloppy wet snow in Sioux Falls. Parts of northern South Dakota into southwestern Minnesota could get an inch or more.

Black Friday and the weekend will be sunny and warmer. High temps will reach the mid to upper 40s on Friday, Saturday and Sunday. Parts of central South Dakota will warm into the 50s. Another system will roll in late Sunday, bringing rain Sunday afternoon followed by rain and snow Sunday night, Monday and Tuesday. If you are going to be traveling this weekend and plan to return on Sunday, keep an eye on the weather because roads could get icy by late Sunday afternoon.

Strong Storms with Heavy Rain Today

Heavy rain is falling across parts of south central and southeastern South Dakota this morning. A Flash Flood Watch remains in effect for parts of southeastern South Dakota and southern Minnesota through this morning. Thunderstorms will continue to produce rainfall amounts of 1 to 3 inches with locally higher amounts of 4 or more inches.

Rain will exit from west to east by mid morning, but showers and thunderstorms will continue to be a possibility later today, tonight and again tomorrow. More heavy rain will be possible with the additional threat of a few strong to severe thunderstorms later today into tonight.

The weather will calm down late Wednesday and leave us with a mostly sunny and mild day Thursday. Scattered showers and thunderstorms will return late Thursday night and Friday. As of right now, I think the weekend will be mostly sunny with high temps in the 70s.

Hot & Humid… Strong Storms Later Today & Tonight

Today is going to be hot and humid. High temperatures will range from the upper 80s to low 90s with the dew point hovering somewhere in the upper 60s. That will take the heat index into the mid to upper 90s this afternoon.

A powerful cold front is rolling into the very northwestern corner of South Dakota this morning. That front will blast across the Dakotas and into Iowa and Minnesota late today and tonight, bringing good chance of showers and thunderstorms. Storms will develop across central and northern South Dakota late this afternoon into this evening and move east through the night. Our latest models are suggesting that storms will approach the Sioux Falls area by mid to late evening. Some storms could be severe with large hail and damaging straight-line wind gusts being the main threat. The tornado threat is relatively low however, an isolated tornado or two is possible. Timing on storms could change, so stay with me throughout the day for updates. Some places could get heavy rain. One-half inch to an inch or more is possible through tomorrow night.

Tomorrow will be mostly cloudy and cooler with scattered showers and thunderstorms likely. The best chance of severe weather tomorrow will be across Nebraska, Iowa and south central to southeastern Minnesota.

The rain should be out of here by the weekend. Saturday and Sunday will be partly cloudy to mostly sunny and quite a bit cooler. Highs will only reach the upper 60s to low 70s on Saturday, warming to the mid 70s on Sunday. The cooler weather will not last long, we will bounce back into the 80s by Monday and stay there through most of next week.

Sunny, Warm Days Ahead… Storms Thur/Fri

It is going to be sunny, warm and somewhat humid for the next couple of days. Highs will reach the mid 80s in Sioux Falls today while parts of central South Dakota warm into the low to mid 90s. Tomorrow will be warmer and a little breezier with high temps ranging from the low 90s in Sioux Falls to the mid 90s across central South Dakota. It’s not going to be quite as humid as it was the last time we had a string of 90 degree days, but you will definitely notice the humidity.

A powerful cold front will blast across the Dakotas Thursday and Friday, moving into Iowa and Minnesota late Friday into Saturday. That front will bring a good chance of thunderstorms, and some of them will probably be severe. Severe storms are possible across central and northern South Dakota Thursday afternoon and Thursday night, the severe weather threat will shift to southeastern South Dakota, southern Minnesota, eastern Nebraska and western Iowa on Friday. Storms should end by late Friday night in most places, however, they could linger into Saturday morning across the extreme southeastern part of our KSFY coverage area.

After the front passes, cool and dry Canadian air will slip in from the north. Saturday and Sunday will be mostly sunny with highs only reaching the low 70s Saturday, we will warm back to the mid to upper 70s by Sunday.

Scattered Storms Today, A Nice Weekend Ahead

Today will be partly to mostly cloudy, warm and humid. High temperatures will only reach the mid 80s but the dew point will be back in the upper 60s to low 70s which will make it feel sticky. Thunderstorms will develop along east of the James River by early to mid afternoon and move east into Iowa and Minnesota by early evening. Some storms could be severe with large hail and damaging straight-line wind being the main threat.

After the storms roll out, drier air from the northwest will roll in. Tomorrow will be sunny with temperatures similar to today, but it will be a lot less humid. The weekend will be partly cloudy with highs in the mid 80s. An isolated late afternoon or nighttime thunderstorm is possible, especially across northern South Dakota.
