Snow Accumulates As We Near Month's End

With holiday programming scheduled for this Friday, there will not be a WeatherTalk segment on Minnesota Public Radio's "Morning Edition" news program.  So I am sending along an abbreviated version of Minnesota WeatherTalk early this week.......MS
Snow Accumulates: This past week both Monday and Wednesday brought snow to parts of the state.  A rapidly moving Alberta Clipper deposited 1-3 inches of snowfall in many places on Monday, and then a more moisture-laden system dropped snow across southern Minnesota and northern Iowa on Wednesday, with some amounts over 4 inches.  This made travel on Wednesday difficult for many going away for the Thanksgiving holiday.

Some observers reported record-setting snowfall amounts on November 26th.  Among these were: 6 inches at St Peter and Amboy, 7 inches at Mapleton, 8 inches at Winnebago, 8.5 inches at Fairmont, and 11 inches at Faribault.  As the month of November comes to an end this weekend, a number of observers have received o…

Coldest November since 1996

Coldest November since 1996: Following the winter storm of November 10th, cold air has dominated the state.  Through November 20th average monthly temperatures are running from 6 to 9 degrees F colder than normal, marking the coldest November since 1996.  A streak of 12 consecutive days with no temperature reading of 32 degrees F or higher at MSP is the 2nd longest for the month of November, topped only by 15 consecutive days back in 1880.  Pete Boulay of the Minnesota State Climatology Office has a nice feature on this.

In addition a number of observers have reported new daily record cold maximum daytime temperatures this week.  In fact at least 120 climate stations set such records this week, including the following:
On November 14th: 18 degrees F at Browns Valley and Ottertail; 19 degrees F at Melrose; and 21 degrees F at Owatonna
On November 15th: 19 degrees F at Austin; 17 degrees F at Litchfield; 16 degrees F at Madison; and 21 degrees F at St Cloud
On November 16th: 21 degrees …

First Significant Winter Storm and First Sub-Zero Temperatures

First Winter Storm: The first significant winter storm of the autumn season crossed the state over Monday and Tuesday (November 10-11) this week depositing several inches of snowfall in many places.  The heaviest band of snow ran through Madison, Willmar, St Cloud, and Mora, over to Rice Lake, Wisconsin with most observers reporting 10 to 14 inches over the two days.  The largest total snowfall reported from the storm was 16.5 inches at St Augusta (Stearns County) and Cambridge (Isanti County).  The storm made both commuting and longer distance travel difficult across central Minnesota counties, and was the cause of many traffic accidents.  A synopsis of this storm is provided by the State Climatology Office.

Some observers reported new daily record snowfall amounts for November 10th, including Benson (6.7"), Moose Lake (8.0"), Dawson (10.0"), Princeton (11.0"), Collegeville (12.0"), Milan (13.0"), St Cloud (13.2"), and Isanti (14.0").  Addition…

Second Annual Climate Adaptation Conference

Some snow this week: Some snowfall accumulated across central portions of the state on Thursday, November 6th, the first widespread accumulation of the season so far. Many areas of Crow Wing, Cass, Aitkin, and Pine Counties reported 1 to 2 inches of snow. The largest reported amount was near Malmo in Aitkin County where 2.4 inches of snow fell. This snowfall is a precursor to another more significant snowfall that is expected statewide over this coming Sunday through Tuesday.
Report on Second Annual Climate Adaptation Conference: Highlights include:
-Climate trends are clearly showing greater variability in some severe weather elements, including heavier rains, cluster outbreaks of tornadoes, more large hail, and seasonal changes in peak risk periods for hail, strong winds, and tornadoes. Peak season for heavy rainfall has shifted to August in our region.
-More research with reanalysis of upper air data and high resolution climate model outputs will be useful in further d…
