You can see temperatures were well below normal, and precipitation way above. In fact, last month was officially the 3rd coldest October on record in Sioux City, being beat out by 1925 and 1917. Last month was also the wettest October on record ever in Sioux City, a whopping 3.71″ above normal! That’s almost half an inch above the now #2 spot — 5.30″ in 1979. Snowfall was another impressive stat from last month. Sioux City’s 1.8″ ranks as the 10th snowiest October on record. The top spot for snowfall belongs to 1991 with 9.8″.
Looking at a calendar of last month, its not too hard to imagine that it was wet. The image below shows all the days where there was at least a trace of rain at the Sioux Gateway Airport, those days are shaded green. The orange days, all 7 of them, are the day without any type of precipitation at SUX.
It seems that November may be trying to win the favorite month award. Following the chilly October, November started off with highs across Siouxland in the 60s and even a couple 70s on Sunday. The rest of the week doesn’t look quite as warm, but high temperatures should still be quite mild.
