New HRRR model run, Friday timing. Estimates only. May change:
- Rain arriving bt 4 PM – 7 PM
- Rain to Sleet to Snow bt 9 PM – Midnight
Most snow to melt on impact. Little to no accumulation.
Bridges, Overpasses, and Areas at Higher Elevation may be slick late Friday night thru Sat AM. Expecting below freezing temps late Friday night until about 9 AM Sat. Bridges and overpasses are the exception because they cool down way faster than earth.
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:
- Temps are about to drop fast.
- But precip will pull east and away from us quick.
- The 700 MB chart shows the base of the trough getting here late, delaying local rain/snow transition.
- While flakes may fly, surface temps should be too warm for accumulation.
High elevations may get dusted. 99% of us nah.
Off/On downpours. Storm center remains south. Some lightning there. Radar below at 305 PM.
Precip will continue tonight. Mix of rain/snow. Few/No impacts locally. Higher elevations may see a dusting — those up a big hill, Fairview, SE Will Co, and other high spots. HRRR model thinks rain/snow gone by midnight.
