Here’s the deal, Minnesota. A strong clipper is going to bring a swath of 3-6 inches of snow late Wednesday night and throughout the day Thursday, but exactly where the area of snow up to six inches hits isn’t completely clear just yet.
The latest information from the NWS is that there is high confidence of 3-6 inches of snow north of Interstate 94 and a dusting or no snow in southwestern and south-central Minnesota. Stuck in between those two areas of high confidence is the Twin Cities, which could get accumulating snow or experience a bust.
Why the lower confidence for the metro? The NWS is talking about the dreaded “dry slot,” which is simply dry air that makes it harder for snow to develop in part of the storm. That dry slot is definitely going to prevent snow from piling up in far southern Minnesota, but it remains unknown if the dry air will get as far north as the metro.
What’s becoming more and more intriguing, however, is that the dry slot was well-represented by earlier runs of the HRRR model, but the 7 a.m. HRRR update Wednesday brings the heaviest snow right through the Twin Cities.
