.SHORT TERM...(Today and tonight)
Issued at 349 AM MDT Wed Oct 21 2020

Currently...satellite imagery shows widespread low stratus across
the Eastern Plains, mainly east of I-25.  Observations are not
indicating any fog or drizzle at this time, but would not be
surprised if either occurs through the early morning hours,
especially over Baca County.  Winds remain breezy along the
Continental Divide.  Temperatures are generally in the 40s across
the region, with 20s in the San Luis Valley.

Today...an upper level trough is forecast to dig south out of the
northern Rockies by this afternoon, but remain well to our north.
This will lead gusty winds over the Central Mountains, down into
Fremont and Teller Counties this afternoon.  Humidity values are
expected to fall under 15 percent, creating critical fire weather
conditions over these areas this afternoon.  Added Fremont and
Teller Counties to the Red Flag Warning.  Elsewhere, near critical
fire weather conditions are expected from the La Garita and San Juan
Mountains, into the southern San Luis Valley this afternoon.  While
a few areas will see critical conditions, did not have enough
coverage or persistence to issue.  Caution is advised over these
areas.

On the Plains, low stratus is forecast to hand around through the
morning hours, slowly dissipating by late morning.  Again, patchy
fog and drizzle may be possible, primarily over Baca and Prowers
Counties this morning.  This cloud cover will likely help keep
temperatures a bit cooler out near the Kansas border where highs
will reach near 70.  Further west, better mixing and clearing skies
will allow for highs to reach into the upper 70s to lower 80s.

Tonight...the upper level trough will shift east across Wyoming
remaining to our north.  As it passes to the north, the gradient
will tighten across Colorado with westerly flow prevailing aloft.
Models are indicating some potential for downslope winds, mainly
along the lee slopes of the Rampart, Sangre de Cristo and Wet
Mountains late tonight.  While not the most favorable set up (winds
are a bit to southwesterly), a few gusts near 50 mph may be possible
in wind prone areas into the morning hours.  These winds will also
help keep temperatures elevated along the lee slopes, with overnight
lows in the 50s, while further east on the Plains, lows will fall
into the 40s.  Where winds remain elevated, humidity recoveries will
be poor, with near critical to critical fire weather conditions into
Thursday morning. Mozley

.LONG TERM...(Thursday through Tuesday)
Issued at 349 AM MDT Wed Oct 21 2020

A couple of troughs will affect the weather during this period.
Confidence is quite high that it will be getting much colder.
Confidence is also high that we will see some widespread precip over
most of the area, however, per ensemble guidance, confidence is
lower on how much precip we will get.

The first concern during this period will be the first cold front
moving down the plains on Thursday. Red Flag conditions will be
possible, but it will be dependent on how fast the front comes
through, and how fast the low level RH will recover. Confidence is
high that we will reach RH and wind criteria in the San Luis Valley
(SLV), but confidence is lower for the plains due to the timing of
the fropa. For now, due to timing concerns, will leave the fire
weather hilite for parts of the region on Thursday as a Fire Weather
Watch, and will allow later shifts to get a better feel for the
timing of the front.

As for temps Thursday, NBM viewer showing very little spread in max
temps values over the area which indicate high confidence that we
will see another warm day across the region, with max temps around
70 across El Paso county and mid to upper 70s over most of the rest
of the plains. Some 80s likely far southeast plains.

Cold temps are likely Friday morning, with lows in the 20s across
the plains. Very little spread was once again indicated in teh NBM
indicating confidence is high with these readings. It should be
noted that this cold air with the first front is rather shallow, as
mtn/valley min temps for Fri morning are rather warm, with readings
on tin the 30s with some low 40s.

Friday will remain cool over the plains with readings in the 40s most
areas with 50s in the Raton Mesa region. The mtns and valleys will
be quite warm with 50s and 60s for highs. Interestingly, guidance
has warmer temps for Leadville (51F) than for most of the plains
(40s). SLV should have the warmest temps this day.

The warm airmass over the mtns/valleys on Fri will push out over the
rest of the region on Saturday, and it will be quite warm all areas
on this day. Red flag conditions will be possible once again,
especially along the southern I-25 corridor region. Spread in the
temp guidance (ensembles and deterministic) is rather low, so
confidence higher than normal for a very warm day Saturday.

Things start to change Sat nite/Sunday as a much stronger trough
moves into the region. Confidence is very high that it will be
getting much colder, however there is quite a bit of spread on how
much colder it will get. In addition, pops will be on the increase.
Confidence is high that that we will see snow develop over the
central mtns and this precip is expected to move south and east as
the day progresses. Temps will cool off across the plains and
central mtn area while the SLV will likely remain mild, with highs
in the 50s.

For Sunday night and into Monday, sensible weather will be dependent
on the orientation and strength of how the trough evolves over the
region. EC is strong but a bit farther south while the GFS is more
progressive but has the best lift moving over the region. At this
time confidence is high that it will be sharply colder, but confidence
is not that high on how MUCH precip we will get overall. For now, it
appears the overall best chance for heavier precip will be over the
SW mtns with all of the mtns getting some snow. Other areas,
including the plains, will likely see some precip, but amounts still
need to be determined.

for mid week next week, confidence is in the cellar regarding
sensible weather solutions due to the evolution and movement (and
strength) of the 2nd trough. GFS is more progressive and moves the
system out of the area by later Tuesday, while the EC moves a closed
low over the state during the mid week time period. Hopefully, the
EC guidance verifies as this would keep a threat of precip along
with cooler weather over the area for a longer period of time, and
we all know we could use the moisture. \/Hodanish

This hazardous weather outlook is for portions of central...east
central...south central and southeast Colorado.

.DAY ONE...Today and Tonight

Critical fire weather conditions are expected from late morning
through early this evening over Lake, Chaffee and Fremont and Teller
Counties, where dry vegetation, strong wind gusts up to 40 mph and
low humidity will create high fire danger. Near critical fire
weather conditions will also exist along the Continental Divide and
southern portions of the San Luis Valley this afternoon.

Poor humidity recoveries are expected overnight along the lee slopes
of the Rampart Range and Eastern Mountains.  Downslope winds could
gust to near 50 mph late tonight into Thursday morning.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday

For Thursday...critical fire weather conditions will be possible
across the central mountains, the southern mountains, the San Luis
Valley and the southern I-25 corridor region and then eastward
along the Colorado and New Mexico border.

For Saturday, critical fire weather conditions will once again be
possible along the southern I-25 corridor region.

Saturday night, a strong cold front is expected to move across the
region. This system will bring a chance of snow to the most if not
all of the region Sunday and into Monday. significant  snow fall
accumulations will be possible across the central mountains and
the southwest mountains. High temperatures on Monday may not get
above freezing across most if not all of the plains.

For Tuesday and Wednesday, there is lots of uncertainty during
this period, and unsettled weather will be possible.

.SPOTTER INFORMATION STATEMENT...

Weather spotters will not be needed today or tonight.
