Special Weather Statement
Special Weather Statement issued January 10 at 9:18PM EST by NWS Louisville KY
Jan 10, 9:18 PM
→ Jan 11, 11:00 AM
Scattered snow showers are expected Sunday morning along and
behind a cold front. Temperatures are forecast to drop below
freezing through the early to mid-morning hours behind this cold
front. A few of these snow showers could be heavier, causing a
rapid drop in visibility and a quick coating on roads. It will
also be quite blustery, with winds from the northwest gusting to
around 30 mph. The winds will also help limit visibility in snow,
creating briefly difficult travel conditions.
Elevated surfaces like bridges and overpasses will likely become
slick earlier. Anyone traveling Sunday morning should be prepared
for sudden visibility changes and potentially slick road surfaces.
Overall, snow accumulations will be light (half inch or less) and
quite localized in nature. Not everyone will see a dusting of
snow.
