Spotty accumulations of around an inch or less are expected in the southern half of Minnesota Thursday night into Friday, but the National Weather Service is watching a another storm system that is set to impact southern Minnesota over the weekend.
Right now – and this could change in the next few days – the weather service is anticipating accumulating snow Saturday night into Sunday, with the best chance for amounts over three inches between Interstate 94 and Interstate 90 in the southern half of the state.
The snowfall forecast map below will definitely be adjusted – they always are as new information comes in – but there could be a narrow band of fairly impressive snow totals.
"As of now, snowfall amounts will generally be around 3-6” (darker blue), with a narrow band of 6-8” (yellow) possible," says the Twin Cities office of the National Weather Service.
Key points about the storm from the NWS situation report:
- "The system is still over 3 days away, so the storm track will likely shift. For that reason, it is too early for specifics on snowfall amounts."
- "Small shifts in the storm track will change snow amounts for your location."
- "As of now, it appears most locations will see around 4 to 6 inches."
The situation report goes on to say the west-to-east narrow band of heavier accumulations (6-8 inches) will be about two counties wide. That's very narrow, meaning snow totals outside of where the heaviest band of snow sets up could be quite a bit less.
What's more is that the NWS does not anticipate knowing precisely where the narrow band of heavy snow will set up until at least Saturday, so again, expect changes to the forecast.
