I haven’t seen this product anywhere, aside for the National Weather Service office in Chanhassen, Minnesota. This might be because there is no Weather Service office I am so personally invested in as my local office. They have a winter weather page that they haven’t been able to break out very often this year, but with a deep, moisture rich system headed towards the Twin Cities, now is the time to explore all this page has to offer.
First a little background for the pending storm. The heaviest snow storms generally come from the south, where they can fetch the necessary moisture, deepen as the round their way out of a deep trough, and pull cold air towards it as the system moves to the north. The system, arriving tomorrow afternoon, will continue through the day Friday, and will bring a bunch of snow from Sioux City, Iowa to the Twin Cities. There is currently a blizzard watch from Sioux Land in South Dakota and Iowa to southwestern Minnesota, just outside the Twin Cities metro. Now, if only there was a more precise way to estimate how much snow that part of the world will get.
Check out these informative images from NWS Twin Cities at http://www.weather.gov/mpx/winter I don’t even need a caption for them because they are that comprehensive and informative! Check out the actual site, for a percentage break down of the chance for specific amounts of snow at specific locations.
