A warm day is ahead for most of KELOLAND. Temperatures will be in the lower to middle 80s with a NW wind at 5 to 15 miles per hour. Clear skies are expected tonight with cooler overnight lows. Temperatures will range from 45 in Aberdeen to 53 in Sioux Falls. Sunny skies are forecast tomorrow with pleasant temperatures in the mid to upper 70s. That same trend will hold into Friday, with highs a little warmer in western KELOLAND.
Changes are ahead for the weekend. First, areas of rain will develop in western South Dakota Friday night, and will likely spread east on Saturday. This means a 40 percent chance of rain in Sioux Falls Saturday, with slightly lesser chances in Aberdeen. The projected clouds and chances of rain will also keep temperatures cooler. Sioux Falls may have trouble just hitting 70 for a high on Saturday. Rain chances should diminish for most locations on Sunday except for Western KELOLAND. Another round of scattered rain is possible on Monday, mainly in the southeast. Temperatures are looking a little warmer at the end of the 7-day forecast, with 80s in the outlook.
The 7 to 10 day forecast is looking more interesting. On one hand, the Climate Prediction Center is forecasting much above normal temperatures in the plains September 18th through the 24th. However, the new European model is suggesting frosty weather in parts of the Dakotas late next week. We will be watching the data closely for any new trends that develop. Stay tuned.
