A cold front moved through the Texas Panhandle during the afternoon hours of the 22nd. The post frontal airmass allowed temperatures to drop below freezing shortly before 12:00 AM CST on the 23rd. These subfreezing temperatures threatened sensitive vegetation during the start of the growing season. Overnight lows ranged from 26 degrees at Bushland (Potter County) to 32 degrees at Canadian (Hemphill County). Residual cold air advection prevented surface temperatures from warming above freezing until 11 AM CST on the 23rd.  The overnight low at Amarillo (Potter County) of 30 degrees tied the record low temperatures for the 23rd set in 1909.
