A chill is in the air again Friday with temperatures to remain below normal a second consecutive day. It’s even possible a little patchy frost could form Friday night well away from the city proper and the warmth of Lake Michigan.
Friday’s predicted afternoon high of 63° marks only the fifth time since Meteorological Autumn began on Sept. 1 a daytime temperature has been as cool or cooler. Temperatures since the season began have averaged just 62.5°—a reading 2° below the 136 year long term average (since 1871) here, but even more impressively, 7.5° behind the comparable period a year ago. We’ve enjoyed only a quarter of last fall’s 80° days in the past 36 days—five compared to last year’s 22 by this date.
Cool as it’s been here, temperatures dipped to 28° Thursday morning at Hayward, Wisc. and 20° at Embarrass, Minn.
