It was another extremely cold morning across KELOLAND. Most every place was below zero – and many were in the teens below zero.
We started the day clear and cold, but now clouds are streaming in from the west and south. Light snow has already started falling in central and western South Dakota, though snowfall amounts in those locations will be minimal – well under an inch.
Tonight will be cloudy, with light snow picking up in intensity overnight. We expect amounts will be in the 2-5” range along and east of the James River – where a Winter Weather Advisory is in effect. Heavier amounts will be possible in the extreme SE corner of South Dakota (Clay and Union counties) and NW Iowa to SW Minnesota, where a Winter Storm Warning is posted.
With very light winds, overnight temperatures will be in the single digits to the teens.
Tomorrow will be cloudy, with the snowfall continuing in eastern KELOLAND in the morning and early afternoon before ending by evening. Fortunately, wind speeds will be low, so we do not expect blowing snow problems. Temperatures will be in the upper teens to low 20s.
Thursday will be partly cloudy, and we’ll get a temporary break from snowflakes. Highs will again be in the upper teens to low 20s – which is still much-below normal for late February.
We’ll have more chances for snowfall Friday and Saturday into Sunday morning. Temperatures will be in the teens to mid 20s. We still have significant differences in forecast models with regard to the strength of snowfalls, but I think it is safe to say the snows could bring a few inches to several inches. I know that is not very specific, but we’ll be able to time things better once the current snow event ends.
We have another shot of cold air Monday and Tuesday, so temperatures will drop back a bit. But we’re also seeing the potential for more snow in that cold air starting Monday afternoon through Tuesday.
One thing that hasn’t changed is the outlook beyond the 7 day forecast. Every night for the past three weeks I have put a similar graphic on TV stating this: Below or much-below normal temperatures for the remainder of February and at least the first week of March are LIKELY. Look at the longer range climate models (different than our daily forecast models), we would believe temperatures would continue colder than normal through at least the first three weeks of March.
