We conclude January 2020 in Chicago having 16 out of 31 days (including today) with no visible sun, tying the all-time record of 9 consecutive days without sun set on 9 January 1992. We've had only 24% of possible sunlight this month, making this the third-gloomiest January on record after 1998 (20%) and 2011 (23%).
But this is really just a consequence of our unusually mild winter. Since December 1st, we've had 46 out of 60 days above freezing, and only 6 days below -10°C. And mercifully, the forecast for tomorrow and Sunday calls for warmth (11°C on Sunday, fully 9°C above normal) and sunshine (20% predicted for tomorrow, and 90% predicted for Sunday).
So, all right, I can live with more than a week of gloomy skies in exchange for unseasonably mild weather in January.
