Some snow flakes could mix in with the rain tomorrow in the Mid-Atlantic as colder temperatures push into the region. No accumulation is expected for most, but some of the higher elevations in the Appalachians could see a little accumulation.
Surface temperatures are likely going to be too warm for any sort of accumulation in the lower elevations… with most areas in the upper 30s or lower 40s. The freezing level is forecast to be somewhere in the 925-950 mb range, which gives the snow enough time to reach the surface before melting.
Snowfall rates are expected to be fairly light if/when the changeover does occur, which is more evidence that the chance of accumulation in the lower elevations is slim.
Here’s a sounding of the 12z GFS forecast for 1pm tomorrow… the 12z NAM has a lower freezing level than the GFS.
