Snowstorm Dorothy Final Forecast

Here is the final update for much of Minnesota’s first real snowstorm, Winter Storm Dorothy. Many people have been waiting and anticipating this snowstorm for a while now, so here it is in all its glory! Dorothy will make its way through Kansas and up to Wisconsin, bringing a large swath of snow to Nebraska, Northwest Iowa, Southern Minnesota, and Wisconsin. Areas in the center of the path should get around 10” of snow and some spots could even see above a foot of snow. The storm should start at 5pm at the MN border, an 8pm beginning as you get to North St.Paul. This was a tricky storm to track with all its sudden shifts but I think I have finally gotten it all narrowed down. So, expect 8”-12” in the hardest hit areas and 5”-8” as you get into areas like Minneapolis and Sioux Falls. On the southeast side there will be a sharp gradient of heavy snow transitioning into rain in the La Crosse area, totals will rapidly drop from double digits to zero. It seems like that is all for this storm; I will always inform you if there is a sudden, extreme change in the future but this one is pretty solid. Make sure you are safe during your holiday travel and Happy Thanksgiving! All remaining live/real time updates will be on my Twitter @weatherkannon with 24/7 coverage as the storm hits.

Snowstorm Dorothy Update

A semi-large winter storm is going to occur the day before thanksgiving and impact a lot of holiday travel Wednesday morning. A low pressure system from Canada will dive down to Colorado strengthen, then makes its way through Iowa and Wisconsin which will give much of the upper midwest a good chunk of snow. The storm should hit Nebraska Tuesday AM then start reaching Minnesota and Iowa Tuesday PM and last till about noon Wednesday. The main areas that will receive the most snow is much of Nebraska, Northern half of Iowa, All of southern Minnesota, and much of Wisconsin. Totals should be greater than 12” in much of Nebraska, then the storm will weaken and drop up to 12” in the heaviest bands. I waited longer than usual to post about this storm due to the uncertainty of the track, but now that the storm is on land we get a better view of where it will go. Even though the NWS has issued watches for this storm already, there is still a chance that this storm can shift North East or South East. I am posting a probability map to show where the storm is looking like it will currently track. I will release my final forecast around 9pm tomorrow with my snow Total map included, expect changes to be made!
