Area forecast discussion
National Weather Service Morristown Tennessee
306 am EDT Friday Oct 24 2014
Short term (today and tonight)...
high clouds are streaming over the area this morning in association
with a middle-upper level trough. Most of these clouds should be east
of our area by the afternoon...leaving mostly sunny skies for most
of the area. A vorticity maximum moving across northern sections may keep
some clouds over that area. A warming trend will continue...with
highs in the middle 60s north to lower 70s south. Clear and calm
conditions can be expected tonight with a building ridge
aloft...with lows in ther upper 30s to middle 40s.
Long term (saturday through thursday)...
gonna be getting warm early next week as impressive upper ridging
builds over the area. Have the potential to see 80 degrees Sunday
and Monday especially in the southern Tennessee Valley. Ridge pattern will
shift eastward...allowing shortwave to spread precipitation over the area
during midweek. But this could be a wait-and-see kind of pattern
change given the advertised strength of the early week ridging...it
may persist a little longer and hold off the precipitation chances
likewise. So...while chance-category probability of precipitation will fill the forecast
from Tuesday night until Thursday... expect some refinement of that
forecast over the next couple of days.
