Tricky Friday AM Commute Possible

As Kira mentioned in the post below, more wintry weather on the way for Friday AM, with the Northern areas impacted the most. So here is a quick update and not much has changed. A Winter Weather Advisory is in effect for the Northern and Central counties of Delmarva. A light snow, sleet, freezing rain mix will develop in the pre-dawn hours on Friday with a quick changeover to plain rain South to North by mid-morning. The Northern areas will be locked into some colder air longer so the changeover will take longer to occur, probably by late morning.

The best chance for a snow and sleet accumulation would be up North in Talbot, Caroline, Queen Anne's, and Kent county, DE, where 1-2 inches is possible. Central areas may see a coating to an inch, with just plain rain to the South and East. Timing will be a big player for the winter precip. If everything starts earlier, then there is a better chance for accumulations. If it takes longer for the moisture to reach the ground, the less chance for accumulation and frozen precip, as temperatures will be warmer. Remember the worst type of wintry precip is freezing rain, it only takes a light glaze of ice to cause travel problems.
