Special Weather Statement
Special Weather Statement issued February 24 at 5:05PM EST by NWS Mount Holly NJ
Feb 24, 5:05 PM
→ Feb 24, 7:00 PM
Abundant sunshine today allowed for some melting of the snowpack
that is over the area. Going into this evening, temperatures will
fall into the 20s with loss of diurnal heating. Any runoff or
standing waters will quickly freeze, especially on untreated
roadways.
Black ice is difficult to see and makes roads very slippery. Slow
down and give yourself extra time to travel tonight.
