A Frost Advisory has been issued for western Pennsylvania as well as portions of eastern Ohio and northern West Virginia for tonight. The combination of light wind and low temperature in the 30s favors frost formation that could damage sensitive outdoor plants. Consider taking action before the overnight period to protect sensitive plants.
Confidence is increasing for portions of eastern Ohio, western Pennsylvania, and northern West Virginia to see near freezing to sub-freezing temperature Thursday night. A Freeze Watch is in effect to highlight this potential; if conditions remain favorable leading up to that night, a Freeze Warning may be issued that highlights the potential impact freezing temperature has on vegetation and/or uncovered outdoor piping.
A dry cold front is expected to move through the forecast area today. This will bring some colder temperatures for Thursday and Friday. High pressure remains in control for the most part with dry conditions expected.
NWS Pittsburgh has six regional climate sites: Pittsburgh, PA (KPIT); Wheeling, WV (KHLG); Morgantown, WV (KMGW); Zanesville, OH (KZZV); New Philadelphia, OH (KPHD); and DuBois, PA (KDUJ).
