Sioux Falls, SD
This is one of the coldest mornings of the winter so far with many spots in eastern KELOLAND at or below zero. Temperatures will rebound today, but highs will be in the low to middle 20s in the east, with lower 40s in Rapid City. A batch of clouds will cover much of central KELOLAND.
We expect lows tonight to be a little warmer with lows in the mid teens in the east and lower 20s in the west. Some light snow will develop tonight in the northeast and flurries in Sioux Falls. Warmer weather will be likely tomorrow with highs returning to the lower 30s in our eastern areas with middle 40s in the west. This warming trend will continue into Sunday when widespread 40s are likely. This will be the last warmer day for awhile.
Sharply colder weather is forecast next week. Highs will drop into the mid teens to mid 20s on Monday and will likely stay at least that cold much of the week. We could even stay in the single digits for highs in the north, a trend we’ll watch. There will be a couple of chance of light snow, one Monday night and Tuesday. The other chance will arrive on Thursday. We won’t have to get much snow to make a big dent on highs next week.
The very cold air will remain in Canada and the northern tier of the U.S. for the next 10-15 days. We will be caught on the border of this, meaning we’ll likely be dealing with wild swings in temperatures across KELOLAND from west to east. We already see some significant warming by the end of next week, but the cold air only retreats a bit to the north. Periods of snow will also be possible in the last half of January, but we have yet to see any major storms showing up in the long range forecast.
