Earliest SunsetDecember 9th, 2012 at 3:35 am by Bill Steffen under Bill's Blog, Weather
The earliest sunsets of the year occur this weekend at 5:08 PM here in G.R. We actually sit at 5:08 PM from Dec. 4 through Dec. 13. The sunrise (currently at 8:03 AM today, 12/10) will continue to get later until reaching our latest sunrise at 8:14 AM from Dec. 29th thru Jan. 7th. The combined shortest day is the Winter Solstice, which is coming up on Dec. 221 at 6:12 AM. That day we have only 9 hours of possible daylight (sunrise 8:11 am and sunset at 5:11 am). Temperatures lag the position of the sun by around one month, so our coldest day on average is around January 20th. The average high temperature drops another 8 degrees from Dec. 10 to Jan. 20 and the average low temperature drops 10 degrees. So, on average, these mixed precipitation events would be all snow if they came later in the winter. Remember, it’s dark when many of the kids head off to school here in December and January, so keep that in mind on your morning commute. (another fine picture here from Jack Martin).
