Midday Update: Big North-South Variation In Tuesday PM Snowfall
November 4, 2013 — 2:01pm
On Edge. Here is the 12z 4km NAM solution, showing potential snow amounts across central and southern Minnesota and western Wisconsin. Note the sharp gradient from north to south, maybe 1-2" for the northern suburbs, as much as 3-6" in the central core of the metro, with some 5-8" amounts not out of the question far southern suburbs, closer to 10" from Redwood Falls to Le Center and Northfield with up to a foot from north of Rochester to near Eau Claire. We'll see, but I want to stress a few variables that will keep amounts down slight: ground temperatures are still mild, after a few days of 40s and 50s. So snow will initially melt on contact during the late afternoon hours. Precipitation will start out as rain, and the strongest vertical velocities with this system may slide just south of MSP. Bottom line: probably plowable Tuesday PM (especially south metro), but hardly Snowmageddon! Map: NOAA and Ham Weather.

Snow falls north of the MSP metro area Sunday, but we're still on track for a couple inches of slush Monday. By the time the system really gets going, fueled with moisture from the Gulf of Mexico, it'll be too far east for heavy amounts here. Another coating of flakes Tuesday gives way to blue sky by midweek. Check the blog for more details. -Todd Nelson
A little snow and ice is possible this morning, but most of the significant snow on Sunday will fall over central and northern Minnesota. There's another chance of snow Monday, when an inch or two may fall on the metro, but this may wind up being more of a nuisance event for the immediate Twin Cities, but plowable over parts of central and northern Minnesota.
Admit it, 30s feel pretty good. Imagine what 50F or 60F will feel like. Today will feel more like late January, although blue sky and a higher sun angle will help to remove some of the sting. A clipper may spark a coating of snow Saturday, a warmer front dropping some accumulating snow on northern Minnesota Sunday. Monday's snow event looks less impressive, but a little slush is possible as we start the work week.
Yes, Wednesday was a salve for the senses - just what the doctor ordered. It was the first day above freezing in 18 days, so we can be forgiven for doing cartwheels (badly). Flurries mark the introduction of a cooler front today - you'll need a coat Friday, but another thaw arrives over the weekend before a (growing) chance of accumulating snow on Monday. Stay tuned.
