Not Exactly Snowmageddon: Quick Burst of Slush Overnight (1-2" north metro; 3-4" south metro)
November 5, 2013 — 4:16pm
Not Exactly Snowmageddon. Temperatures (air and ground) are simply too warm for a huge, snowy dumping. It's not going to happen. Here's 4 km NAM data with our own algorithms for conversion from rain to snow, showing a sharp north-south gradient in snowfall amounts across the area. I expect an inch or so from Willmar to Medina and Anoka, maybe 2" from Chaska and Minnetonka to Minneapolis and Shoreview, as much as 3" of slush for St. Paul and Mendota Heights, maybe 3-4" from Lakeville to Woodbury and Cottage Grove. A few spots in Scott and Dakota county could wind up with 5" of sloppy snow, but after melting and compaction of this (heavy/wet) snow it may wind up being closer to 3" actually on your lawn. I expect wake-up temperatures around 31-32F early Wednesday, so there may be some slushy/slick roads, but I expect MnDOT to keep the freeways mostly-wet overnight. Slow, yes, but hardly a worst-case scenario. Again, road conditions will get trickier as you head south of the Minnesota River later tonight and early Wednesday, but even there it will be borderline "plowable". Any snow in your yard should be gone by Thursday, Friday at the latest as temperatures rise into the mid-40s.

I predict precious few complaints about the weather today with pleasant temperatures and low humidity; summer heat in retreat for now. A few more waves of heat return next week - although probably not as torrid as last week. Most of us probably won't see rain until Monday. Mosquitoes? No promises there...
Only in Minnesota can you be knee-deep in flood waters with dust blowing in your face. Weather has always been extreme at this latitude, but there's growing evidence the swings are becoming even bigger. Which brings up the challenge (and opportunity) of managing water: too much water, or not enough water. More showers sprout today but generally dry weather is likely Friday into Sunday as temperatures moderate. The first week of August may feel more like mid-July.
Another free lawn-watering today (showers and T-storms, probably not severe) gives way to a clearing trend and a drop in humidity Thursday. The upcoming weekend looks lake-friendly, warm, but not obnoxiously so. Next week may see a few more 90s with a couple days of dew points in the oh-zone.
Monday was a fine summer day; a touch of heat and humidity, but not as swamp-like as late last week. We may brush 90F today before cooling off later this week - a good chance of heavy showers and T-storms Wednesday and Thursday. Long-range models hint at another hot front as early as next week.
