Cold Conclusion to December

Cold Conclusion to December: Cold weather dominated Minnesota and much of the nation for the last week of December. Minnesota reported the coldest temperature in the nation on 7 days during the month of December (so far). For the Twin Cities the week between Christmas Day and New Years Eve will be one of the coldest since 1886. On Christmas Day Wind Chill values at places like Orr, International Falls, and Warroad ranged from -40 to -45 degrees F. Both Kabetogama and Cotton set new record lows on December 28th with readings of -40°F and -42°F, respectively. International Falls reported a new record cold maximum temperature for December 26th with a reading of -12°F, while Embarrass and Pokegama Dam only "warmed up" to -18°F that day setting records for cold maximum temperatures. At International Falls a new record cold minimum for December 27th was set with a reading of -37°F. Even more cold temperature records may be reported over December 30-31 this weekend. Thankf

Oscillating December Temperatures and 2017 Climate Review

Oscillating December Temperatures and 2017 Climate Review: Through the first three weeks of this month most climate observers have reported average December temperatures that range from 3 to 7 degrees warmer than normal. With the projected colder than normal weather dominating the Christmas to New Year’s Day time period, it appears that by the end of the month most climate stations will find that December mean temperatures have balanced out close to normal. Minnesota has reported the coldest temperature in the nation only twice so far this month, but is likely to see this frequency increase over the last ten days of the month. This oscillating temperature pattern is what balanced out the month of November as well, expect the first half of the month was exceptionally cold and the second half of the month exceptionally warm. January may continue this oscillating pattern as it starts out colder than normal, then moderates mid-month and may even warm to above normal during the secon

Mixed climate patterns in December

Mixed climate patterns in December: After an extraordinary warm start, with scores of record high temperature values set on the 4th of the month, December has been tracking with alternating periods of below and above normal temperatures. Overall through the first half of the month most climate stations are showing average temperature values that range from 4 to 8 degrees F warmer than normal, a trend that is likely to make December the 10th month of 2017 with above normal temperatures. Over 60 climate stations so far have reported subzero low temperatures on at least one day this month, with a minimum of -19°F near Ely earlier this week on the 12th. Embarrass was -15°F on that date as well. Eveleth reported -9°F on December 8th, the coldest in the nation. Most observers have so far reported anywhere from 5 to 7 days with measurable snowfalls, mostly light in amounts from a dusting up to 1 inch. Though most climate observers have reported a total of just 1 to 4 inches so far t

Winter Returns

Winter Returns: This week the Minnesota State Climatology Office posted the headline "Winter Returns" referring to the snow and cold front that dominated the state over December 4-5. Prior to the passage of the cold front during the afternoon and evening of Monday, December 4th many climate stations reported new record high temperatures for the date, including: Rochester and Austin with 64°F; Albert Lea and Theilman with 63°F; Grand Meadow with 62°F; Minnesota City, Fairmont, Hastings, Caledonia, Winnebago, Waseca and Winona with 61°F, Amboy, Red Wing, and Preston with 60°F; Rosemount with 59°F; La Crescent with 58°F, MSP with 57°F, and a number of other places as well. In addition MSP reported a new record high dew point on December 4th of 55°F, and the 2nd highest dew point ever reported in the month of December (only a dew point of 57°F on December 5, 2001 was higher). With the high temperatures and high dew points during the afternoon a few thunderstorms developed a

November climate summary

November climate summary: Precipitation was generally below normal across Minnesota during the month of November, while the temperature pattern was mixed with average monthly temperatures that were cooler than normal in the north and slightly warmer than normal in much of the south. The other contrast was in cloudiness, which was dominant the first half of the month, then there were many long spells of sunshine during the second half of the month. The first two weeks of the month were the coldest since November of 1995, but then temperatures moderated the rest of the month, with several days bringing daytime highs in the 50s and 60s F. The last week of the month was about 12°F warmer than average in most Minnesota communities. Extreme temperature values for the month were 65 degrees F at Marshall (Lyon County) on the 27th, and -17 degrees F at Camp Norris (Lake of the Woods county) on the 24th. Minnesota reported the coldest temperature in the nation four times during the month
