Dense fog developed overnight, resulting in visibilities of 1/4 mile or less. Newspaper reports indicated that many icy frost deposits occurred on roads and bridges. Snowmelt due to maximum temperatures in the mid to upper 30s on February 26th contributed the moisture needed to saturate the air as the night progressed. Newspaper reports indicated that some vehicle accidents occurred.
