.DISCUSSION...
KEY MESSAGE 1)

Thunderstorms continue to move across the region. Due to the

conditions are expected for Friday. Precipitation chances return for
Saturday. There is some variability with this system which has kept
precipitation chances lower, however there is the potential for
showers and storms during the day. There is more model agreement on
Sunday with widespread precipitation moving through. There will be
the potential for some residual showers and storms Monday morning.

&&

with some of these storms. LLWS will also be possible overnight along

expected for awhile for the daytime morning hours. Additional showers
will develop for the afternoon and have tempo shra in the TAFs.
