ELC Winter Event #11

LIGHT SNOW EVENT

FINAL RECAP 1/6/15

1/5/15 Snow TotalsSNOW ½” seems to be the name of the game with last night’s snowfall. The NWS’s snow analysis (to the right) is indicating heavier totals that we received. This is a radar-created analysis and not actual snowfall.

NORTHEAST 0″ to ½” fell in the northeast Metro.

SAND/SALT Temperatures are so low that rock salt will not help to melt anything. If you have areas that are slippery, use a sand/salt mixture for traction.

Event Chronology:

  • 11 pm Snow ending across metro with light accumulations
  • 6 pm 1/5/15 Snow begins falling.

ORIGINAL POST

SNOW Greater MSP is the cutoff for snow in today’s event. Heaviest totals will be in the west and southwest metro with less than ½” in White Bear Lake and up to 2″ in Chaska.

TIMING Snow will begin mid-afternoon from sw to ne with heaviest snow during the evening hours Monday. Snow will end by 6 am and should be able to be fully plowed by Tuesday morning.

Loop from 12 pm through 6 am Tuesday for forecasted snow.

COLD Temperatures are brutally cold and will stay this way for a majority of the week. Plowing with temps in the double digits below zero is very tough on equipment. If enough snow accumulates to plow, expect breakdowns and possible delays in plowing for Tuesday morning.

ICE Temperatures are too cold for most salt to work. Rock salt is the commonly used salt on parking lots and is completely ineffective at temps this low. Anticipate some icy conditions in parking lots after tonight’s plow from compacted, cold snow.

SIDEWALKS Calcium chloride and Magnesium chloride salts are marginally effective in temperatures this cold but too costly to apply to parking lots. They also can cause damage when tracked into buildings. Be sure you vendors are not over-applying to compensate for the cold temps.

COMMUTE At these low temperatures, any snow will freeze to roadways and create black ice and nasty conditions. MnDOT will be unable to keep them clear because – as you learned above – rock salt will not melt at these low temperatures. Use extra caution and give yourself time for the next few morning.
