Low Temps. Weds. AMFebruary 12th, 2014 at 9:06 pm by Bill Steffen under Bill's Blog, Weather
This is a map of low temperatures Weds. morning. You can see the cold air from E. Montana across the northern U.S, Ohio Valley and into New England. Grand Rapids bottomed out at -6, the sixth below zero morning of the winter. Even more impressive was the -11 at Holland (Regional Airport) and -12 at S. Haven. Holland did make -12 on 1/23/2011, but I looked back to 1994 and didn’t see a temp. as cold as -11 in any February. Holland did have 3 consecutive days of -10 from Feb. 3-5, 1994. In the eastern part of the Lower Peninsula, Ann Arbor dipped to -20 and LaPeer and Port Huron bottomed out at -18. Even the usual warmest location of Flint fell to a double-digit below zero -11. In West Michigan, Marshall had -17, Three Rivers stopped at -16, Charlotte’s weather station hit -15. It was -14 in Coldwater, -13 in Algoma, -12 in S. Haven and Ionia, -10 at Kalamazoo, -9 Alma and Mt. Pleasant, -8 at Benton Harbor, -7 at both Jackson and Battle Creek, -6 at Sturgis, -5 at Big Rapids and Oshtemo, -3 in Lansing (which was a cold spot until they moved the weather station to a warmer location) and -2 in Muskegon. Where the lake-effect clouds held all night it was warmer. Frankfort never got lower than 14 (31 degrees warmer than Marshall), Ludington stopped at +10, Cadillac at +2 and Fremont’s low was +1.
You can really see the difference Lake Michigan makes. Green Bay has had 40 mornings with low temperatures below zero this winter. That’s the 6th highest number ever. The record is 48 in the cold winter of 1976-77. Chicago is in 4th place for most below zero mornings with 22. Chicago’s record is 25 in 1884-85.
Other low temps. this morning: -30 Saranac Lake NY, -20 Cheboygan and Petoskey, -18 Defiance, Ohio, -16 Aurora IL, -15 Fort Wayne and Goshen IN and -5 Chicago. At the weather station at the Chicago water intake, 3 miles east of downtown out in the lake, the high/low on Feb. 11 was 14.3/4.4. You can grow a lot of ice with temperatures like that and nearly calm winds.
February has been very cold east of the Rockies. The temperature anomaly (difference from average) for Feb. 1-11 was -4.668C (more than 8 deg. F). The U.S. is draggin’ down the whole planet. The Feb. 1-11 temperature anomaly for the globe is -0.127C. However, if you include January (and a very warm Australia), you get a global year-to-date anomaly of +0.037C.
