.SHORT TERM...(This evening through Friday)
Issued at 247 PM MDT Thu Oct 12 2017

...Cooler weather heading towards the region...

Currently...

Sat pix indicate mainly clear skies over the region. A few clouds
were noted over the higher terrain, especially across the San Juans.
Temperatures were unseasonably warm, with temps ranging in the 80s
most of plains. KLAA was 90 while the springs were in teh mid 70s.
Over the higher terrain, the valleys were in the 60s to around 70F.
The mtns were generally in the 40s.

Breezy conditions were noted over the higher terrain, with breezy
conditions also noted over parts of the San Luis Valley and the
Spanish Peaks region.

A cool front was noted along the CO/Wy border, and it was
progressing steadily south.

Tonight...

main weather concern tonight will be the passage of the front which
was moving south into Colorado at this time. This front will bring a
gradual wind shift to the plains later this evening as the front
goes by. Some gusty winds may occur with the fropa. Otherwise expect
dry and mostly clear weather.

Tomorrow...

Much cooler weather will occur tomorrow across the plains as temps
are expected to be a good 12 to 18F degrees cooler than today. Winds
across the plains will veer as the days go by, becoming
southeasterly by afternoon. Over the mtns, southwest gusty winds will
continue although it will be 3 to 6F cooler than today.

.LONG TERM...(Friday night through Thursday)
Issued at 247 PM MDT Thu Oct 12 2017

Friday night through Saturday...An upper low pressure trough will
cross the Pacific NW Friday evening, then the northern Rockies on
Saturday. The trough axis crosses Colorado through the day Saturday,
with a sfc cold front forecast to drop south across the Palmer
Divide and eastern plains by midday. Ahead of this front, very brisk
bordering on strong westerly winds are expected, which will combine
with low humidity levels to create the potential for critical fire
weather conditions for the San Luis Valley Saturday aftn. Therefore,
a Fire Weather Watch has been issued there. Elsewhere, look for high
temps in the 60s for most areas though the far southeast corner may
warm up into the mid 70s.

Sunday through Thursday...Dry conditions settle back in across the
forecast area through the rest of the extended period, as cool
northwest flow on Sunday transitions to a warmer westerly flow
beginning on Monday. Look for max temps in the 50s to lower 60s for
most areas on Sunday, then for Monday through Wednesday expect highs
in the 60s for the high valleys, and 70s for the eastern plains.
