.DISCUSSION...

Upper level low to move across the deep south today. An
associated sfc low is currently located over eastern AR. This
feature will not encounter any appreciable pva and will therefore
be weakening as it moves east. Thus...a likelihood of rain shower
activity is in the fcst, but due to weakening, rainfall amounts
will be on the low side. Shower chances will persist into tonight
but again, qpf will remain light.

On Wednesday, a few showers will linger early across the Plateau but
clouds should remain area wide for the most part. On Thu, light and
low shower chances to return, but pre frontal dynamics look really
sketchy.

Showers and tstms will be possible Friday aft and eve, a few storms
could become strong. Otw, temps will become more seasonal over the
weekend and into early next week.
