The worst of the cold weather is here. Morning wind chill will remain in the -40 to -55 range in much of eastern KELOLAND, with slightly better numbers in far western SD. This type of weather is truly life-threatening if you are not prepared for it. Highs will be -10 to -15 in much of eastern KELOLAND and slightly warmer numbers toward Rapid City with highs near 11 above. Northwest winds will be generally at 15-20 mph.
The wind will go down Monday night, but the temperature will still plummet to -19 in Sioux Falls and even colder weather in western MN and northeastern SD. Winds will be down to 5-10 mph.
Tuesday will improve as the mercury climbs above zero in most areas by the late afternoon. Some light snow or flurries could develop in northern and northeast SD as a warm front develops. Look for 30s to return to Rapid City…a sign of things to come for the rest of KELOLAND.
The forecast for Wednesday won’t be much warmer, but at least we won’t fall much either. Bigger jumps in the mercury are expected on Thursday with highs near 21 in Sioux Falls and 40s toward Rapid City. The temperature will continue to get better this weekend with widespread 30s and 40s likely. In fact, this may be just the start of a true “January thaw” into next week as temperatures stay at or ABOVE normal.
