Rain Friday Afternoon, Splat:Melt Flurries Friday Night, Cold Saturday

Beautiful day today with BNA nearly getting to 70° today.

Rain moves in tomorrow.

HRRR model (above) shows:

  • rain moving in early Friday afternoon
  • cold air moves in from the NW, causing our temps to go from the low 60s Friday afternoon –> low to mid 30s Saturday AM
  • that cold air will be chasing the precip exiting our region, may cause rain to briefly change over to snow
  • expecting any snow that falls to melt on contact with the ground, no accumulation is expected
  • bridges and overpasses may be slick Saturday AM

Saturday will be dry but will also be the coldest day we’ve had in a while. High temperatures may not make it to 40°… read more

Very little/no snow expected locally tonight.

Deets: Notice the surface low (the red L below) that’s now just passed to our south. It’s racing to Knoxville then Carolina mtns.

This means:

  1. Temps are about to drop fast.
  2. But precip will pull east and away from us quick.
  3. The 700 MB chart shows the base of the trough getting here late, delaying local rain/snow transition.
  4. While flakes may fly, surface temps should be too warm for accumulation.

High elevations may get dusted. 99% of us nah. read more
