Record warmth abruptly ends

Record warmth abruptly ends: The record-setting warmth of the first 17 days of November (temperatures 13-15°F above normal) abruptly ended this week with a strong winter storm which ushered in widespread precipitation, some heavy snow, very strong winds, and cold air. For the first time since mid-October many communities will see their first below normal temperatures over this coming weekend, and central and northern Minnesota will receive the first significant snowfall, with many western counties under a blizzard warning. Although this weather event will bring an end to the historically warm pattern it is likely that with moderating temperatures for the balance of November, we will end up with one of the warmest Novembers in state history. In addition much of the model guidance suggests that the first ten days of December will be warmer than normal as well.

One additional note to add on the first half of November comes from Dave Ruschy, who for many years managed the St Paul Camp…

Warmest first ten days of November

Warmest first ten days of November: The remarkable warmth so far this month is record-setting. For example in the Twin Cities, the average temperature for the first ten days of November is 53.7. This is nearly 14F above normal and surpasses the other warm first ten days of November which occurred in 1975, 2001, and 2015. This pattern is holding true at a number of locations around the state, including International Falls where the first ten days of November are average close to 46F also about 14F above normal. This too surpasses the other warmest Novembers of 1964, 1975, and 2015.

So far this month 32 daily high temperature records have been set within the Minnesota Cooperative Weather Observer Network across the state, including a remarkable reading of 78F at Mora (Kanabec County) on the 5th which tied the all-time state high temperature record for that date (set at Madison in Lac Qui Parle County back in 1975). In addition a handful of warmest overnight minimum temperature r…

Warm start to November

Warm start to November: Most climate stations in the state are reporting daily temperatures that range from 8 to 15 degrees F above normal for the first few days of November. This pattern is expected to persist well into the month, and may approach the record warmest first half of November which dates back to 2001 That year was the only time the Twin Cities saw daily temperatures average above 50°F for the whole first half of November. Everybody is asking when the other shoe will drop. Perhaps not until the 16th or 17th.

This warm pattern conforms to the year-long trend in Minnesota temperatures which is persistently warmer than normal. In fact the state has recorded the 4th warmest first ten months of the year (Jan-Oct) in 2016, and the 3rd wettest such period as well.
Summary of record-setting daily climate values for 2016: The current year has been a warm and wet one for Minnesota in no uncertain terms. Among the state's 131 Cooperative Observer Climate Stations, here i…
