BRIDGEPORT, W.Va (WDTV) -- From Meteorologist Timothy Albertson...
Frost development is looking possible for tonight, especially in our northern counties and in the high elevation counties.
Temperatures this afternoon have been in the 50s for the most part, and once the sun sets, most - if not all - of the clouds in our area will quickly dissipate. This will allow heat to escape quickly from the ground, which in turn will make our temperatures drop fairly fast.
I am expecting that tonight's air temperatures in Clarksburg will reach 36°. These temperatures, combined with the calm winds, create a favorable environment for frost development.
In Meteorology, the temperature we forecast is measured at 2-meters (6 feet) above ground level. The cooler the air, the more it "sinks" down to the surface. So long as the winds are calm, this prevents "mixing" (warm air being brought down to the ground), and thus the temperature right at ground level may reach 32° or lower. This is why frost can develop even though the *air* temperature is 36°.
Your forecast for tonight in Clarksburg...

West winds at 5-15 mph with gusts up to 25 mph possible during the early evening, becoming calm during the late evening and overnight.
