Snow fades: Icy roads linger Saturday

Our latest winter storm has delivered a steady powdery snow to the metro and southern Minnesota as advertised.

As of 1am Saturday Glencoe takes the Golden Snowshovel award with 9″!

I will not be surprised to see isolated 10″ totals come in this morning south & west of the metro with this prolific powder producer.

Snow burst continues late Friday night on MNDOT traffic cam at Hwy 41 & 212 in Chaska.

1 1 1 1 1 1 1 7.JPG

A hefty 6.5″ of fresh powder in Deephaven at 11:30pm Friday night.

Radar trends (and model data) shows snow tapering during the overnight hours, but not before another shot of 2″ to 4″ for many locations from the metro southeast.

1 1 1 1 1 84.PNG

NAM model paints another 2-4″ by 6am in the metro, with heavier totals in SE MN.

1 1 1 1 1 1 1 MPX_loop.gif

Snow gradually tapering west of the metro late Friday night.

That will bring storm totals into the hefty 4″ to 8″+ (with some isolated 10″ amounts possible!) range under the heavy snow axis just (and I mean just) south and west of the metro.

The range across the metro looks like from 3″ far northeast….to a good 6″+ in the south metro, with some isolated 8″ totals possible far SW metro by morning.

Here are some snowfall totals late Friday evening:

(Including a whopping 8″ at Litchfield west of the metro!)

Evening update:

Snowfall update 8pm:

-Mankato 7″

-Northfield 5.8″

-Shakopee 4.5″

-Bloomington 4.2″

-Farmington 4″

-Deephaven 3.5″

Snowfall intensity peaking between now and midnight in most of southern Minnesota, including the metro.

I’m still forecasting a range of 3″ to 6″ across the metro by 6 am Saturday. The best chance of 6″+ in the southwest metro, Norwood, Waconia, Shakopee, Prior Lake. More likely to see 3″ in the northeast metro…Wyoming, Lino Lakes, Scandia, Stillwater.

The heaviest snow band will run between Willmar and Redwood Falls through Hutchinson, Glencoe, New Ulm, Mankato, New Prague, Northfield, Waseca, Owatonna and Rochester. 4″ to 8″ can be expected in these areas, with some isolated 8″+ totals possible.

1 1 1 1 1 1 earl1.PNG

The radar is lighting up with brightly colored heavier snow bands moving through the metro and points south this evening. These bands of higher radar “reflectivity” indicate areas of heavier snowfall, with rates approaching (and in some cases exceeding) 1″ per hour.

1 1 1 1 1 1 MPX_loop.gif

MNDOT traffic cams continue to show snow coming down heavily, and snarling traffic around much of the metro.

1 1 1 1 1 1 mndottyy.jpg

Snow burst continues at Highway 212 & Highway 41 in Chaska.

1 1 1 1 1 1 280.jpg

Snow covered and slippery at I-94 & Highway 280 in St. Paul

Visibilities continue to run in the 1/2 mile to 3/4 mile range in moderate snow in much of Minnesota.

Here are some of the latest snowfall totals from the Twin Cities NWS.

Update 5:30pm:

Snow intensity now ramping up in the metro. Weather Lab “streetlight snow doppler” confirms reduced visibility and increased snowfall intensity.

1 1 1 1 1 1mndot2.jpg

MNDOT traffic cam on Highway 212 & 41 in Chaska shows heavy snow burst!

More scientific readings confirm visibilities down to 1/4 to 1/2 mile in moderate to at times heavy snowfall from the SW metro south and west.

1 1 1 1 1 1 1 mn.jpg

MNDOT cam at I-494 & I-35 shows traffic crawling along in south metro.

Latest radar trends continue to show “bright banding” indicating areas of heavy snowfall just SW of the Twin Cities metro. These areas look in line to see some 4″ to 8″ snowfall totals by early Saturday AM.

1 1 1 1 1 1 1 wun.gif

Latest snow totals include around 2″ and accumulating rapidly in the SW metro, and 4″ in Willmar.

Road conditions will continue to be poor through tonight in much of west central, southern Minnesota and in the Twin Cities Metro. Prepare accordingly!

On the good side, thius is indeed a dry powdery snow, which will make for excellent skiing and outdoor play this weekend.

Enjoy….if you don’t have to drive tonight.

PH

Update 4pm:

Doppler radar “Bright Bands” continue to favor areas in the SW & west metro and points south along I-35 to Northfield. Snowfall intensity is picking up as a whole over the metro now…with the heaviest bursts in the south & SW metro.

From Twin Cities NWS…

SNOWFALL REPORTS FROM SPOTTERS…AND VISIBILITIES FROM AIRPORTS…INDICATE RATES WITHIN ONE TO TWO INCHES PER HOUR IN THIS BAND.

1 1 1 1 1 1 1 wundy.gif

Expect snowfall rates to reach 1″ per hour in the southwest metro over the next 1-3 hours.

I’m still forecasting a range of 3″ to 6″ across the metro by 6 am Saturday. The best chance of 6″+ in the southwest metro, Norwood, Waconia, Shakopee, Prior Lake. More likely to see 3″ in the northeast metro…Wyoming, Lino Lakes, Scandia, Stillwater.

The heaviest snow band will run between Willmar and Redwood Falls through Hutchinson, Glencoe, New Ulm, Mankato, New Prague, Northfield, Waseca, Owatonna and Rochester. 4″ to 8″ can be expected in these areas, with some isolated 8″+ totals possible.

Snow:water ratios are quite high (around 16:1)…meaning a dry powdery snow.

Update 3:15pm:

Snow intentisty is building now west of the metro and into the SW metro at this hour.

1 1 1 1 1mndotty.jpg

MNDOT traffic cam at I-494 & Hwy 100 shows a worse than usual rush hour.

Radar indicates “bright banding” or areas of higher reflectivity associated with bigger (more reflective) snow flakes (stellar dendrites) from near Glencoe moving into Carver County near Waconia, and spreading into the south metro to New Prague. These bands can yield snowfall rates of 1″+ per hour.

1 1 1 1 1 1 wxund.gif

“Bright Bands” setting up just SW of metro.

Expect snow intensities to increase in the metro over the next 1-2 hours, and a nasty PM rush…expecially in the southwest half of the metro.

Redwood Falls already has plied up 5″ of powder…with more 2″ and 3″ reports coming in my the minute.

Here we go!

Our next Minnesota winter storm is getting cranked up this afternoon and tonight.

An impressive band of snow has developed on schedule and is moving east into the metro this afternoon. It looks like the snow will be here beofre PM rush in much of the metro, and there may be enough light snow to slick up roads for Friday PM rush today. Plan for a little extra time getting around this afternoon… and especially this evening.

1 1 1 1 1 mndot 11.jpg

MNDOT traffic cam shows snow and slick roads already along Highway 212 & Powers Blvd. in Chaska in SW metro.

Roads are already slick west of the metro including Redwood Falls, New Ulm, Mankato, Hutchinson, Glencoe, Fairfax, Willmar.

Here’s the latest on the increasing winter storm.

Snow is increasing in basically south of I-94 to the Minnesota River Valley. Already some snow reports coming in including:

Snow is blossoming on radar as it moves into the metro. Light snow began at 1:20pm at the Huttner Weather Lab near the east end of Lake Minnetonka, and will spread over the metro by 3pm.

1 1 1 1 1 radar.gif

Metro radar shows snow shield expanding east.

As I suggested may happen yesterday, the latest model runs have shifted the snow slightly to the south. I’m going to trim an inch off my metro forecast from yesterday, thinking 3″ to 6″ by Saturday AM as a range in the metro. Highest totals will likely be in the southwest metro…think Waconia, Chaska, Norwood.

1 1 1 1 1 1 qpf.PNG

Models favoring snow totals between 4″ and 6″ for MSP Airport by Saturday AM.

(Click for bigger image)

It still looks like the heaviest band of 4″ to 8″ will set up along the Minnesota River and north. Willmar-Mankato-Waseca-Owatonna-Rochester.

1 1 1 1 1 earl 2.PNG

NAM model paints heaviest snow band just SW of metro.

Bottom line: The storm is still on track. Expect snow to increase this afternoon and evening. Prepare for slick roads through tonight and into Saturday morning.
