October 27 to November 5, 2017 was the most gloomy end of October and beginning of November since solar radiation records began at the U of M St.Paul Campus Station in 1963.
The weather turned cool, cloudy and snowy across Minnesota in late October and continued into November. The average temperature was below normal for many locations through this period. A fairly significant snow pack developed for the time of year over north central and north east Minnesota and small lakes began to freeze over.
The skies began to clear on November 6, and on November 7 there was plenty of sunshine across the state, putting an end to the gloom. Temperatures still remained cold and for the first week of November (1-7) the statewide average was 8.4 degrees below normal.
