NAM 12 KM Model Total Rainfall Forecast Next 84-Hours
The mountain region is back into another dry stretch, being caught between heavy rainfall producing systems well to the northwest and east. Yes, again a subsidence regime will rule.
While a shower working in from the east or northeast can not be completely ruled out, most of the region along and west of the Cumberland Mountain range looks to remain dry.
GFS Model Total Rainfall Forecast To 8 AM Sunday – September 25, 2016
If conditions remain dry through Saturday that would be great news for the 10th Annual High Knob Naturalist Rally to be held in the majestic High Knob Lake Recreation Area.
*As always this is sponsored by The Clinch Coalition and their supporters and is an awesome event for all ages. And it’s free.
The first real cool shot of Autumn 2016 is still being tracked to arrive by the middle of next week. Initial indications are that the coolest air will move across the Great Lakes into the northeastern USA, but some impact is expected across the southern Appalachians ( stay tuned for details ).
