Periods of light snow into Thursday, then temps drop

Milder next week before Thanksgiving

Expect periods of light snow and flurries on Tuesday, Wednesday and Thursday, followed by a cold snap with highs likely in the teens Friday and Saturday. Next week looks milder.

Light snow continues

It will be cooler than normal on Tuesday. High temperatures will be mainly from the upper 20s to low 30s. The Twin Cities should see about 33 degrees during the afternoon with a southeast breeze of 5 to 10 mph. Light snow will continue to stream north out of Iowa

Periods of light snow and flurries should stay with us on Wednesday and maybe into Thursday.

Road conditions will remain much better than they were on Monday thanks to chemical treatments and warmer temperatures. Most snowfall accumulations through Tuesday night will be around 1 to 3 inches. Lesser amounts are likely in the northwest corner.

More heavy snow for northeastern Minnesota

Minnesota’s Arrowhead region will continue to get heavy lake-effect snow into Wednesday. A winter storm warning for Cook and Lake counties will continue until 6 a.m. Wednesday as easterly winds blow off Lake Superior.

Why were roads so icy, hazardous on Monday?

Roads quickly became icy and led to far more crashes and spinouts, some at rather high speed, than would be expected from such an event when Minneapolis-St. Paul International Airport measured just 2.5 inches of snow.

I did some analysis of the conditions in my driveway to get at the answer. Here in a nutshell is what seems to have occurred:

  • ·Some of the first snow that fell melted on contact with pavement that was above freezing.

  • ·Chilly air temperatures in the mid 20s and cold falling snow froze that bit of water into a thin layer of ice. Snow that continued to fall remained cold and did not melt atop the ice.

  • There had been no previous snow events this fall to leave residual snow-melting chemicals on the roads.

  • Roads that probably looked wet to many drivers turned out to be icy and extremely slippery.
