Feb 5, 8:45 PM
→ Feb 6, 3:00 AM
A fast moving weather system will produce a short 3 to 5 hour
period of accumulating snow overnight into early Friday morning.
While significant snowfall amounts are not expected, a burst of
snow, with rates up to 1 inch per hour, could result in a period
of slick travel due to snow covered roads early Friday morning.
Patchy freezing drizzle is also possible. Accordingly, motorists
are urged to plan for extra time to reach their destination
Friday morning.
