Today��s temperatures are much colder than yesterday. We had afternoon highs in the teens in the east and 20s in the west. A band of light snow has developed in western South Dakota, with energy that will affect much of KELOLAND tomorrow.
Overnight temperatures will drop even as a northerly breeze continues to blow. There is a wind chill advisory for areas east of the James River starting at midnight, when wind chills could feel like -20 or worse. It is not that it will be very windy, just that the temperatures will be cold.
Tomorrow morning��s low temperatures will be subzero in eastern KELOLAND. An area of light snow will move from western South Dakota into the east during the morning and afternoon hours. An inch or two of powdery, moisture starve snow will be possible, mainly along the Missouri River. Amounts will be less in the northern part of South Dakota. Skies will be mostly cloudy, and a gentle northwest breeze will prevent us from warming very much. Eastern South Dakota will see afternoon highs only a few degrees above zero, while teens are expected in the central and west.
It is likely that there will be more dangerous wind chills Saturday night, because the air will be even colder. Saturday night and Sunday morning we can expect air temperatures of 15 to 20 degrees below zero �C and even a light northerly breeze will magnify those extremely cold temperatures.
Sunday will be a sunny day as the center of the cold, dry air mass passes through. But we simply will not warm up. In fact, we expect most of eastern KELOLAND will remain below zero all day long.
Monday will again start very cold, in the -10 to -20 below zero range in the morning. With sunshine, we expect highs to moderate a little bit, in the single digits to low teens. Tuesday we expect highs in the teens, and there might be a little light snow as milder air returns.
Wednesday and Thursday will be slightly warmer, with highs in the lower 20s, only a little below normal. Indications are that we will continue to warm through Friday, and we may even reach the low 30s for the weekend of January 23-24.
