Sioux Falls, SD
Temperatures are much warmer in KELOLAND, but still below zero across parts of the east. We also have a few areas of light snow near Aberdeen, but little accumulation is expected. The snow is being triggered by the warmer shift in the weather and afternoon highs should climb back above zero in most spots, with around 8 in Sioux Falls.
The warmer trend will come to a temporary halt Tuesday night as the mercury tumbles below zero again. Aberdeen may drop to -18 in the morning, with -7 in Sioux Falls. The air on Wednesday will filter out of northern MN, so highs will still be stuck in the single digits in many spots East River, with warmer 20s toward Rapid City.
The bigger trend toward warmer weather will spread east on Thursday with 20s returning to much of eastern KELOLAND on Thursday and 40 degree weather is possible in the far west. We expect the numbers to improve even more on Friday and Saturday as highs return to the 30s and 40s in many areas.
There could be some light mixed precipitation on Sunday in KELOLAND as slightly cooler weather arrives by Monday. However, the coldest air will likely stay to our north and warmer temperatures are possible next week…fitting the definition of a “January thaw” ahead. In fact, the raw data would suggest 60s in Rapid City at some point next week. Stay tuned!
