OSNW3 | OSHKOSH-NORTH

Back on Sep 24th we had a surge of moist tropical air work in from the south. Daytime highs topped 80° as the atmosphere rung out an inch plus of precipitation. Even a few rumbles of thunder were heard as the weather worked it's way across the area. On the backside, cooler more seasonal air enveloped the region opening the door for a real autumn bite. Our first frost at OSNW3 wasn't far behind. On Sep 27 the temperature dropped to 39.3° for an overnight low and a light frost developed on rooftops around the property. The Last time the low temperature dipped below 40 was on May 11, 2010 (39.9°). 140 days prior. Since then, frost has become more frequent bringing our tally of frosts to 3.

Last weekend and the early part of this week our region dealt with two potent low pressure systems that dropped the temperatures and pumped up the winds. I recall acknowledging the high dew points of the summer and foreseeing an extra chill on my skin once they left. The cooler air of September came rolling in but I acclimated quickly. I welcome back autumn with open arms. Forecasts call for a cooler than average period through next weekend.
