Short term...(this evening through monday)
issued at 241 PM MDT sun Sep 22 2019

Dry conditions are expected over the region throughout the short
term forecast period. Precipitable water values are low over the
mountains and mountain valleys, so evening thunderstorms are not
expected. The dry air, clear skies, and light winds will make for
efficient radiational cooling overnight. The cold conditions mean
that a freeze warning will be in place over the San Luis valley
overnight from 0400-0800 MDT. The freeze warning will likely be
the last over the slv since it is indicative of the end of the
growing season. Delicate plants are at risk for freezing and
exposed pipes are at risk to freeze overnight, so take
precautions. The low temperatures overnight are expected to be in
the 40s over the plains, the upper 20s and low 30s over the
mountain valleys, and the teens to 20s over the mountains.

Dry conditions are expected tomorrow, as well. The upper level flow
will shift from the southwest, which will bring temperatures to
above average once again. High temperatures are expected to be in
the mid 80s over the plains, the low to mid 70s over the mountain
valleys, and the 40s to 50s over the mountains.

Long term...(monday night through sunday)

The upper low opens up and moves across southeast Colorado Thursday
night into Friday. Showers and thunderstorms are expected over the
mountains of south central Colorado before a few storms spread onto
the plains Friday. Highs Thursday will warm into the lower 80s to
around 90 degrees on the eastern plains, but temperatures drop
back a few degrees for Friday. Breezy conditions are possible
across the area.

Saturday and Sunday feature a deep trof over the western U.S. With a
building upper ridge over the southeast portion of the country.
