areas of the Mid State during the afternoon and overspreading
Middle Tennessee Sunday night with front moving along the plateau
by 12z Monday. Surface wave develops on front Monday night with

the north. Surface wave moves east rather quickly on Tuesday. A
cold front will approach from the northwest Tuesday night bringing
a chance for flurries after midnight and sprinkles during the day
Wednesday. Flurries after midnight Wednesday night then dry
Thursday and Thursday night and colder as 1034 mbar high settles
down across the area. By 12z Friday euro has developing surface
low Oklahoma Panhandle with retreating surface high centered over
Pennsylvania. 00z Euro brings surface low into northwest Arkansas
by 12z Saturday then opens it up as an elongated inverted trough
with Tennessee in strong warm advection pattern and rising
thicknesses along with very tight surface pressure gradient. This
is a week away so plenty of time to get a better handle on this
feature. As for temps, get ready for a roller coaster ride, so
buckle up and keep a coat handy.
