Saint Cloud November 2002 and fall weather summary

 

The October weather pattern continued in November. While the persistent air flow from the Yukon produced Saint Cloud's second coldest October on record, we ended up with slightly above normal temperatures for November. According to the Saint Cloud Municipal Airport statistics, the average temperature was 29.8 degrees, a degree above normal.

The main news of November 2002 was the dry weather. Yukon air contains very little moisture and both the November precipitation (0.11 inch) and the November snowfall (0.4 inch) demonstrated the dominance of Canadian air. This made November 2002 the driest November in 61 years and the 7th driest November in Saint Cloud history. The snowfall total marked only the 5th November in the past 50 years in which there was half an inch or less. The last time this happened was 1981. Despite the dryness, Saint Cloud’s total rainfall for 2002 has now reached 34.94 inches, which ranks as the 10th wettest year in Saint Cloud history with December still to go.

Saint Cloud’s fall (September 1-November 30) statistics are proof of the adage, “Figures don’t lie, but liars sure figure.”

  • Combine a September that was nearly four degrees above normal with the second coldest October in Saint Cloud history, then add a November that had about the same temperatures as November, and what do you get?
    Answer: Fall temperatures that were within a degree of normal, even though the daily temperatures were rarely near normal.
  • Combine the fourth wettest September on record and an October with more than an inch above normal with the 7th driest November on record and what do you get?
    Answer: The seventh wettest fall on record and the wettest since 1985, even though we have only picked up 0.90 inch since October 13.
  • Combine the second snowiest October in Saint Cloud history with only the 5th November in the last 50 years with no more than half an inch of snow and what do you get?
    Answer: A near normal snowfall total for this time of year.

What lies ahead? Well, the National Weather Service has its official winter forecast out (can be found at http://www.cpc.ncep.noaa.gov/). According to this forecast, Minnesota has the best chance of anywhere in the country for a mild winter. The reason for this forecast is the development of El Nino, the anomalous warm ocean condition in the Tropical Pacific (for more, see http://www.crh.noaa.gov/fsd/outlook.htm). However, I look at the weather pattern that we’ve been stuck in for the past 7 weeks and say, “Ha!”

As long as that persistent high stays in British Columbia, our air will continue to come from the Northwest Territories. My only question is whether our temperatures will be near normal or below normal. That depends on how quickly we get snow cover. Snow reflects most of the sun’s energy back to space. Without it, the cold air masses are being warmed more than the usual as they pass over the bare ground over the Northern Plains and much of the adjacent Canadian Prairie Provinces. That factor has kept the temperature from being able to drop below zero during our cold blasts. This northerly flow pattern is very dry pattern so, to get a storm system to produce snow, it will have to pass through Minnesota to the south of Saint Cloud. During the past month, nearly every storm has stayed well to our north, leaving us high and dry. So, that’s the only uncertain point in my mind. Otherwise, I think we can expect a winter with below normal snowfall and normal to below normal temperatures.
