Weather May-Hem: 6″ to 15″; Trees down, Power out to 26k; State snowfall record

Major May “Winter” Storm Sideswipes Metro

This is “The Big One” for May snowstorms in Minnesota. At least for May 2nd.

My MPR colleague Mark Seeley tells me Dodge Center’s 15.4″ just broke the all time sate snowfall record for May 2nd.

Here’s the MPR live blog to keep track of the latest snowfall and damage reports as they come into NWS.

Metro: Tale of two forecasts

Drive half an hour east in the Twin Cities today and you will be forgiven if you feel like you entered another time zone.

In the west metro some clouds and a cool breeze. In the east & southeast metro, wind driven wet cement, tree snapping snow that feels like entering a time warp back to March.

11″ just across the border near Hudson with snowy conditions on I-94 east of the metro?

8″ of heavy wet concrete snow in Cottage Grove in the southeast metro?

13″ to 15.5″ in Owatonna south of the metro along I-35??

I hope MNDOT kept a few plows in ready condition into May.

In this Updraft we count up the inches and document a remarkable May snow event for a relatively narrow slice of southeast Minnesota, the eastern metro and western Wisconsin.

Last night’s last minute eastward shift of about 30 miles spared the central metro core from significant snowfall, and from breaking any snowfall records at MSP Airport. Just don’t tell that to folks in Cottage Grove, Owatonna, Red Wing, Hastings and Ellsworth who are digging out from 6″ to um… 15 inches of heavy wet snow on May 2nd.

Snow continues east:

The band of heavy snowfall continues to run from southeast Minnesota, right up into the east metro into western Wisconsin. These areas can expect several more hours of heavy snow into this afternoon.

Razor’s Edge: Remarkably sharp cutoff on metro snow

I’ve seen a lot of storms in nearly 30 years of forecasting weather in Minnesota.

I’ve never seen a storm quite like this one…especially in May.

This was not your typical, textbook Minnesota winter storm. Not even close. Atmospheric conditions were just right for a very narrow, SW to NE oriented band producing extremely heavy snow overnight. The band of heavy snow was only about 2 counties wide. Dry air cut into the western side of this unusually elongated system…and effectively wiped out snowfall production in the western and central metro.

Check out the remarkably sharp cutoff on the systems back edge which waffled over the eastern metro overnight.

No gradually lighter snow to flurries zone here. It was literally all or nothing…from a wet smack to not a flake in the sky in a city block.

Remarkable.

Prolific snowfall totals: Metro near miss

We just missed the central core of the heaviest snowfall band in the heart of the Twin Cities.

But as expected they got smacked along an Albert Lea- Owatonna-Red Wing-Hastings-Cottage Grove-Ellsworth-New Richmond zone.

Check out some of the eye popping snowfall totals coming into the Weather Lab via Twin Cities NWS.
