The episode as NWS HUN wrote it up.
A strong Arctic cold front pushed southeast through the region during the late afternoon and early evening hours on the 3rd, dropping temperatures from the upper 60s and lower 70s into the upper 20s to lower 30s by the morning of the 4th. Rainfall changed to freezing rain and sleet from northwest to southeast after Midnight through the morning hours. The sleet was the predominant precipitation type, accumulating up to one inch in some locations. Freezing rain accumulated to one or two tenths of an inch before changing to sleet.
Travel became very hazardous as temperatures continued to tumble through the 20s and into the teens during the overnight of the 4th into the morning of the 5th. Numerous schools, government agencies and businesses were closed on the 5th and the 6th due to the hazardous travel conditions. Temperatures rose into upper 30s and lower 40s on the 6th, melting much of the ice, except in shaded locations.
