Drip, drip, gush. That’s pretty much the forecast for snowmelt over the next week.
Snow cover in the Upper Midwest is impressive. But this map will look very different in a week.
We ease into melt mode this weekend as temperatures push past the thawing point across most of Minnesota. Daytime highs above freezing and nights below freezing mean a slow melting process which is good to ease the river flood threat. But that refreeze at night can be tricky.
Here’s the quick glance at temperatures for the Twin Cities for the next few days. With a fairly uniform air mass most of Minnesota will be close to these numbers, a few degrees cooler up north.
Slight weekend snow chance
I’m not impressed with our chances for snow this weekend. But there may be a few renegade snow or rain showers around as a minor clipper zips by. Here’s the Canadian GEM model.
Deeper frost this winter
Frost depth is deeper this year as you would expect after two mild winters. Here’s more from the Twin Cities National Weather Service and the Minnesota Department of Natural Resources State Climatology Office.
Frost depths this winter have been generally deeper than the past two years. Here's a look at current frost depths across the region. Additional info from MN DNR State Climatology Office on frost depths across the state: https://t.co/efnOxDw6lY #mnwx #wiwx pic.twitter.com/3lhhmNLUld

Milder late next week
The jet stream gradually eases north into Canada the next few days. By next Thursday, a fairly amplified ridge of high pressure will make it feel like early spring.
Most models suggest mid- to upper-40s for the Twin Cities and much of Minnesota next Thursday and Friday. I think we’ll see some 50 degree temps late next week in parts of southern Minnesota. And Friday’s inbound weather system appears to be mostly just plain old rain.
Weather fingers crossed. Stay tuned.
