Providing a slightly warmer track of warm weather, high temperatures over the next 7 days are expected to reach the mid-to-high 40's and even low 50's for parts of our area. Surviving a few weeks of frozen temperatures are green duckweed, also known as bayroot or water lentils, floating on top of a small body of water located next to railroad tracks leading into the Mahanoy Tunnel in Barnesville.
