The weather forecasts looks good for tonight (Saturday January 5 2019 at Caledon State Park, King George County). The rain will end, and the grass will probably have some hours to dry before dark. The sky will be clearing, temperatures in the 40s. Be prepared for a bit of wind. Some forecasts say the wind will be light, some say 15 mph.
Sunset is at 5pm today. Twilight will end at 6pm. — Glenn
