DISCUSSION...
Low level moisture has been scoured out by the cold front. Today is
expected to be dry along with lots of sunshine.

Low level moisture will start to return on Sunday. A northwest flow
aloft will help to bring some showers and thunderstorms this way
from the mountains. At this point, it is hard to say if the moisture
will be back in time for showers and thunderstorms in the afternoon,
but there may be enough moisture to help fuel rain overnight. Upper
level dynamics will also improve Sunday night ahead of a short wave
trough which will move through the panhandles Monday. Monday looks
like it will be a good day for showers and thunderstorms as this
short wave trough moves across the region and these dynamics work on
the instability in the atmosphere.

Another short wave trough will move across the panhandles Monday
night into Tuesday which should bring a renewed round of showers and
thunderstorms. The models do not quite agree on the timing of these
short wave troughs, so the rain chances will likely change
accordingly from Monday into Tuesday night.

The forecast will remain dry Wednesday and beyond as heights rise
with a ridge building into the region. Temperatures are expected to
remain around or below normal through Wednesday, then temperatures
should warm above normal.
