There will be a brief possibility for light freezing rain or freezing drizzle late tonight (after 3 a.m.) mainly along and south of the Highway 82 corridor of extreme Southern Arkansas including Lafayette, Columbia and Union Counties, as well as portions of extreme Northern Louisiana north of Interstate 20 including Northern Bossier, Webster, Claiborne, Northern Lincoln and Union Parishes. Areas of light rain and drizzle will continue to spread northeast into these areas this afternoon and evening, before slowly diminishing late tonight.
While rainfall amounts through tonight will be very light (below a 10th of an inch), any residual water in addition to the near freezing temperatures late tonight may result in patchy ice development, especially on elevated objects such as bridges and overpasses. Any ice that may form late tonight will melt by 10 am Wednesday as temperatures climb above freezing.
Again, this is NOT expected to be a significant icing event as any icing that develops will depend on temperatures and the extent of any light freezing rain/freezing drizzle development late tonight. Given this low confidence, we will not be issuing a Winter Weather Advisory this afternoon and later shifts will continue to monitor this potential this evening and early Wednesday morning.
