A colder air mass to bring lake effect snow and seasonal temperatures
Happy Veteran's Day, Northland! Another warm day for Tuesday with highs in the 50s and lower 60s across the Northland, making it feel more like early October than near the middle of November. Overnight, a system made its way through to bring light rain which continues this morning. After a lull early on today, more showers will spark up mainly in northern Minnesota later on into the overnight hours thanks to a shortwave trough passing through. For the South Shore, we will see lake effect snow ramp up and continue through Thursday before subsiding into Friday. Snow totals won’t be significant in the grand scheme of the coming winter but with 1” to 3” possible for spots along the South Shore, it will make a nice coating for this early season snowfall. For this lake effect snow, there needs to be a couple ingredients in place. One is relatively warm water over Lake Superior, and with temperatures still in the upper 40s, this is very much the case. We also need relatively cold air out of the north which is the other ingredient which we will very much have. Temperatures right now are still mild for a November morning, but with the northerly flow behind the cold front, temperatures will generally stay in the upper 30s, 40s, and lower 50s depending on how north or south you are.
