Radar getting very quiet, and only very light snow left. All is well with the forecast. Minimal changes to near term temps. Prev... Wind backing to the SW as the high pressure moves in from the SW. The earlier band which sat for so long over Clearfield and Centre Counties is dead and gone. Not much in the way of radar returns now as the subsidence inversion lowers. Sunshine should increase this morning in the SW and the E should go to full sunshine. Latest CAMs are very consistent in lifting any remaining snow to the north of the CWA before noon. Not enough snow left to fall to justify keeping the advy. So we will drop it now.
