Thursday Afternoon
Partly-mostly cloudy. Hazy. A chance of hit-miss showers and thunderstorms. Local downpours possible. Winds light, except SSW-SW at 5-10 mph along middle-upper elevation mountain ridges. Temperatures varying from 60s to low 70s in upper elevations to the upper 70s to lower 80s.
Thursday Night Into Friday Morning
Any evening showers-storms dissipating. Partly to mostly clear into the overnight with haze and areas of fog. Humid. Winds SSW-SW at 5-10 mph, with higher gust, along middle to upper elevation mountain ridges. Warm with temps in the 50s to lower-middle 60s.
Weather Discussion ( May 2016 )
A final cool night amid what has been a long series of chilly nights ( dominating the May 14-25 period in the mountains ) is poised to give into summer-like humidity.
Golden Orb Weaver ( Nephilidae Family ) Species Working In Late May
A wet May 2016, with 6.37″ of rain officially measured in Clintwood, will get wetter in coming days for some as hit and miss showers and local downpours in thunderstorms develop across the mountain landscape as humidity rises.
Crown-tipped Coral ( Clavicorona pyxidata ) Growing Amid May Wetness
Forecast models are trying to guess where rain will fall during coming days, but in reality that is a very difficult thing to do when rainfall will largely be air mass-terrain driven without any distinct focus over the southern Appalachians ( unlike in the central Plains ).
NAM 12 KM Model Total Rainfall Forecast Next 84-Hours
While not cancelling any outdoor plans heading into the first big holiday to kick off Summer 2016, keep in mind that showers and thunderstorms will be developing in mostly a hit-miss fashion across the mountain landscape. Some of these will likely have downpours of rain, along with always dangerous lightning, so have a backup plan and be prepared to seek shelter.
Development odds often favor locations in and near the major terrain features, with subsequent storm motion and formation then being dictated by outflow boundaries that form as cool air rushes outward from the initial convection to trigger new stuff amid what often appears, at least, to be chaos.
GFS Model Total Rainfall Forecast Next 84-Hours
It remains to be seen how a disturbance over the western Atlantic will impact conditions by later this weekend into early next week, so stay tuned for updates.
