Dayton is part of an early-season arctic blast across the eastern United States. The last time temperatures were this cold happened in 1911.

The arctic blast started with a cold front on Veterans Day. As temperatures dropped rain turned to snow.

By 11:59 p.m. the temperature was 11 degrees. The previous record low was 15 degrees set in 1911. This is the fourth record for the week.
The record high and low was set on Nov. 12. This means the avg temperature of 18.5 degrees set another lowest record and brings the total up to five.
