Discussion...
this morning...an upper level long wave trough is over the East
Coast with an upper level ridge in the SW U.S. Along the back side
of the trough...a disturbance is moving through the middle Mississippi
Valley. This is producing light precipitation in Arkansas with a few flurries
reported in the northwest portion of the state...even with temperatures in
the upper 30s to 40 degrees. This disturbance will Glide along the
western edge of our County Warning Area this afternoon bringing increased cloud cover
as well.

Adjusted the cloud cover for current conditions and projected flow of
upstream cloud cover. Also pushed back the slight chance of probability of precipitation to
be further west this afternoon. Even though the low levels are
drier...there is enough moisture and it is above freezing in the
snow growth zone for a possible flurry early this afternoon.
Temperatures are and will be above freezing at the surface
today...but the wetbulb could assist in a flurry.
Otherwise...sprinkles are possible in the western counties this
afternoon.
