November weather summary and December outlook

November continued the warm and dry this fall. The average temperature in the Twin Cities during the month was 39.3 degrees, and finished 5.6 degrees above normal.  This was the ninth warmest November in Twin Cities modern history.  High temperatures were well above normal for the month, and included a mild Thanksgiving.  It tied a maximum temperature record for November 24th.  Records were set elsewhere across the state.


Looking at other locations around Minnesota, the St. Cloud temperature pattern was nearly identical to the Twin Cities and finished 3.8 degrees above average for the month at 34.2 degrees.


The trend was much the same across the state with above average everywhere.  The eastern half of the Twin Cities metro, and northwestern Minnesota were running five to six degrees above normal.


Dry conditions persisted across the state.  For most of southern Minnesota, this was the driest meteorological fall on record.  The Twin Cities recorded it’s driest fall on record.


Just three tenths of an inch of liquid precipitation fell officially at MSP airport for a total of 1.36 inches for the fall.  This resulted in a deficit of 5.92 inches for the season.  At St. Cloud, 0.23 inches of rain was recorded.  This was 1.15 inches below normal.


Some areas of southwest Minnesota observed less than 5% of their normal November precipitation, which further alleviated the drought situation.  Most of the state received half or less of normal monthly precipitation.


At the end of November, the drought situation was at a “severe” level across southern and the Arrowhead of Minnesota.  The lack of sunlight and daytime heating this time of the year has prevented the drought and fire danger from accelerating.


According to the Climate Prediction Center, December is looking like a normal month compared to the extremes we experienced during previous months.  Normal temperatures and precipitation is forecasted for the month.  The Twin Cities average monthly temperature is 24.5 degrees and liquid precipitation is 0.18 inch.  We are already above normal for precipitation for the month as of December 6th.  MSP has recorded 0.23 inches so far in December.  This came from the December 3rd snow.
