noted in the San Luis Valley. A band of wave clouds was developing
along the mtns/plains interface.

Temperature-wise this morning, things were quite interesting, An
area of single digits was noted from the east side of Pueblo
out east into Bent and western Kiowa county. over the rest of
the plains it was mainly in the 20s, with some low 30s in
eastern Fremont county and far western Pueblo county.
Temperatures in Pueblo West were noted to be in the L30s while
here at the airport single digits were occurring. Elsewhere, it
was cold in the mtns with mainly single digits most places in
the valleys and mtns.

Today...

On the plains, where the snow pack remains it will be cooler than
the rest of the plains. Expect max temps in the 30s in snow packed
areas while the remainder of the plains will be in the 40s.
warmest temps will be over the far southeast sections of the
southeast Colorado plains. Mtns and valleys will remain cool
with max temps in the 20s to around 30 valleys and 10s and 20s
mtns.

A weak disturbance will move into the central mtns this afternoon,
and this will bring increasing chances of snow showers to this
region as the afternoon progresses.

Tonight...

Snow over the central mtns will let up early this evening, but will
once again ramp up significantly later tonight as a much stronger
disturbance moves into the central mtns. A Winter Storm Warning goes
into affect around midnight tonight and will continue into Saturday
night. Winds will be on the increase tonight over the higher

Over the plains, lee troughing will develop and this will allow for
