It’s another chilly morning in KELOLAND with temperatures dropping below zero once again north and northeast of Sioux Falls. Warmer numbers continue in far western SD, a trend that will likely continue the next few days. Highs this afternoon will hold in the single digits above zero for Sioux Falls and Aberdeen, with mid 20s expected in Rapid City and lower teens in Pierre.
A developing south wind tonight along and east of the James Valley will signal the start of a warmer trend with highs tomorrow reaching into the 20s in many areas of eastern KELOLAND. Be aware of wind gusts over 30mph in the Sisseton Hills area of the northeast and also the Buffalo Ridge in SW MN. The warmer trend will translate to middle 40s for Rapid City.
Friday will also be a mild day, but a developing storm system to our south could deliver some sleet, freezing rain, or just plain rain to Omaha, Des Moines, and possibly Sioux City. We’ll watch that for NW IA, but most of KELOLAND will not see an impact from this system. Overall, the weekend still looks relatively mild and highs will be in the 30s and 40s.
Next week will be a warmer week on average, but a series of disturbances will bring periods of strong NW winds to KELOLAND as well. Each front will bring fluctuations to the temperature, with a colder period expected late Monday or Tuesday. A more significant warming trend could develop for a day or 2 just after the 7-day. The biggest challenge will be sorting out the timing of each wave, but we feel confident that the wind next week will be significant at times.
