A new record low for our Goose Lake Weather “unofficial” station was set this morning when winds went calm and the temperature plummeted to -27° at 7 AM. This breaks the previous record of -22 set back in 1999. It should be noted however that we only began recording weather data at this location in 1999 and “official” NOAA/NWS reporting sites typically have records for 30 years or more. The graph clearly shows that the temperature took a nosedive once the wind went calm.

Have you ever heard the term 10:1 snow to water ratio? This means for every inch of water you could have 10 inches of snow. Did you know that this is a myth? The snow water ratio can very greatly from storm to storm and even during a snow event. Today we measured 6.7 inches of fluffy, dry snow and had a water equivalent of 0.11 inches. That is a 61:1 ratio! That’s probably one of the lowest water content snow that I’ve ever measured.
This week will see several episodes of snow along with windy conditions and then brutally cold temperatures…the coldest of the season. A blizzard warning is in effect as I write this and travel tonight and early tomorrow will likely be hazardous. Check road conditions here and stay home if you can.
What a month of extremes! From a high of 61° to a low of -5°. Precipitation was well above normal and included snow, freezing rain, sleet, and rain. An ice storm December 18-19 produced a glaze of 1/2 inch over all surfaces including our weather equipment. Our anemometer was frozen for several days. Warm temperatures melted the snowpack on December 27 and heavy rain (and thunderstorms) added to the runoff. This resulted in widespread flooding. We even were under a tornado watch and a severe thunderstorm warning during the Dec 27th event! Here are more statistics for December:
