Dangerous winds possible tonight and tomorrow…. A bit of snow too.

Wednesday, November 30, 2011 at 9:00 am

10-day Snow Forecast:

Wednesday PM – Thursday AM, November 30

  • Above 6K, 2-4″
  • Bench locations, trace-1″
  • Valley floor, trace”

Friday Night/Saturday morning, December 2-3

  • Above 6K, 1-4″
  • Bench locations, trace-1″
  • Valley floor, trace


Main story today is the potential for damaging winds after the front moves through this evening.  Main front will move through the area during the evening hours with snow showers likely with light accumulations in the mountains and a inch or two possible on the benches.  Snow should be too light to cause any major commute headaches this evening.

Focus then turns to wind event taking shape.  The low pressure system that will drop snow this evening will move south and stall in the desert SW while high pressure builds in the upper Rockies… the counter-clockwise rotation of the low and the clockwise rotation of the high will create a strong easterly flow and pressure gradient right over our area.  Easterly winds like this cause downsloping canyon winds that will whip into the valleys at 50-60 mph with gusts up to 75 mph in wind prone areas of Weber, Davis, northern Salt Lake Counties.  Damage is possible.

NWS put out a great weather story display to illustrate potential impacts:

So be careful if traveling Thursday morning and take precautions with any wind sensitive structures.

A secondary front will move into the area Friday night with a bit more snow and a reinforcing shot of cold air.  High temps in the valleys will be in the 30s Thursday-Saturday with 20s likely in the mountains.  High pressure begins to build early next week, however models diverge significantly in the long term.  Still no concrete shot at major snow in the next 10 days, however things can change. Stay tuned…

    gah, very frustrating.

    at least these winds will hopefully rid us of this disgusting air.

    • Yes, they will definitely do that, but I expect the stagnate air to return early next week.
