Snowfall Totals in inches Nov 12-13 2011 |
The snowfall resulted from two fast moving systems across Western Wyoming.The first included considerable wind at higher elevations Saturday morning. There was temporary afternoon clearing as seen from this photo in Star Valley Ranch.
At the same location on the Ranch this picture was taken Sunday morning where an additional 10 inches had fallen overnight!
The pattern that has resulted in this sudden change over the weekend is still in place as can be seen on this evenings water vapor imagery.
Water Vapor Image Sunday Evening Nov 13 2011 |
A broad area of moisture extends from the Gulf of Alaska southeastward across the Pacific Northwest and pointed toward western Wyoming. What this implies is that while the snow has generally stopped across Star Valley Sunday evening, additional fast moving but somewhat weaker upper disturbances while continue the potential for periods of generally light snow into Tuesday. Another 1 or 2 inches is possible but it appears that another bout of heavy snow seems unlikely.
By Wednesday high pressure will temporarily diminish or end any snowfall threat. It does appear that a major change in the large scale weather pattern will take place by the end of the work week increasing the potential for another significant storm affecting Star Valley/western Wyoming.
