October was a roller coaster month in Lincoln, beginning very active, ending very active, and fairly boring in the middle. The first week included the bulk of the month's precipitation, with multiple daily records being set. The first freeze was achieved unexpectedly on October 11, after many forecasts called for lows well above freezing. After that, only .31" of precipitation fell for the rest of the month. The yo-yo pattern continued, with 80's being recorded on the 18th and 19th. A significant pattern change began on the 24th, as a streak of windy days began, signalling the start of a more active pattern. All but one day that week (Wednesday) recorded a wind gust of at least 35mph, with many days recording gusts over 45mph. Finally, the coldest air of the season was ushered in on the 26th. In turn, the first hard freeze occurred on the morning of the 28th. On the 31st, the first flakes flew around Lincoln! It accumulated more in the Southern part of Lincoln than central or Northern parts, due to a combo of heat island and unfavorable trends, with as much as .5" seen in Southern Lincoln. The airport recorded only a trace, leaving the last October with measurable snow officially still as 2009.
At KLNK, the highest temperature recorded was 84 on the second. The lowest temperature recorded was 22 on the 28th. The highest recorded minimum temperature was 63 on the 2nd, and the lowest recorded maximum temperature was 36 on the 31st. The first freeze of the season occurred on the 11th at 30 degrees. No temperature records were tied or broken for the month. 4.90" of precipitation fell, the bulk in the first 10 days of the month. This is 2.93" above the normal precipitation amount of 1.97" for October. This is good for the 4th highest precipitation amount in October on record. Two daily records were set for precipitation. 1.34" on the 5th, and 1.18" on the 6th. A trace of snow fell at the airport, which is a trace above the normal October snowfall of 0.0".
