We melted more snow and ice today, with mostly sunny skies. Most all of KELOLAND was above the freezing mark, with Sioux Falls and SE KELOLAND – where there is very little remaining snow cover – getting into the low 50s, close to ten degrees warmer than normal.
Skies will be mostly clear tonight, and we’ll drop back below freezing into the 20s with a light westerly breeze.
Tomorrow will be sunny, but slightly cooler than today thanks to a northerly breeze. Highs will still be above-freezing, in the upper 30s to mid 40s East River, to the low 50s in Rapid City. Springtime officially begins at 4:58 Central Daylight Time.
Thursday will be even warmer, with highs mostly in the 40s. Sioux Falls and SE KELOLAND will get into the low 50s, and we’ll start to see more melting of the significant snow cover north of I-90, and especially in NE South Dakota and the upper Big Sioux River basin.
Friday will be also be sunny, and there could be some rain showers West River. But temperatures will continue to soar to above-normal levels. Most of the area will be in the 40s, but Sioux Falls and SE KELOLAND (areas where most of the snow has already melted) will get into the 50s. Of course the strong warming will speed up the snowmelt, and increase the potential for flooding or ice jam flooding as river ice breaks up.
We have light rain showers in the forecast in eastern KELOLAND Saturday and Sunday. Right now it looks like the showers will be light, with the vast majority of forecast models giving us only a few tens of an inch of rain each day. But the flooding threat around rivers and streams will be significant as northern South Dakota will get well into the 40s. Sioux Falls and southern KELOLAND will get into the 50s.
Monday will be slightly cooler, backing down into the low 40s with breezy winds. But with sunshine we’ll warm right back up starting on Tuesday. Wednesday and Thursday will be especially warm, with Sioux Falls approaching 60 degrees before temperatures fall back to the upper 40s to low 50s through April 1st.
