Area Forecast Discussion...UPDATED
National Weather Service Morristown TN
930 AM EDT Sun Apr 22 2018

.DISCUSSION...
Rain is beginning to spread into the area from the southwest, on
track with the forecast, but an update will be issued mainly to
make some changes to the wind products. A Wind Advisory will be
issued for the southern Valley and Plateau areas, and SW NC. With
the NAM showing 925 mb winds near 50 kts tonight, and only a weak
near-surface inversion in the soundings, the winds aloft should be
able to mix down to the surface, particularly on the ridgetops.

Since this appears to be a favorable setup for mountain waves, the
High Wind Warning may need to be expended westward to include a
greater portion of the foothills as well as parts of SW VA. Will
evaluate the 12Z models before making a final decision on this.
