Area Forecast Discussion
National Weather Service Pueblo CO
1122 AM MDT Sat Jun 6 2020

.SHORT TERM...(Today and tonight)
Issued at 342 AM MDT Sat Jun 6 2020

...Potentially Dangerous Weather Conditions Will Likely Affect the
Region Today...

An intense short wave trough will barrel through the region today.
There are very strong winds associated with this system and there is
sufficient moisture to allow for thunderstorms to develop, likewise
rotating convection is likely today. The best forcing will occur in
the mountains, so the highest potential for severe thunderstorm
activity will be over the mountains, all of the valleys and possibly
the I-25 corridor region, especially across El Paso county. The
primary threat will be very strong surface winds, but isolated
tornadoes will be possible. It needs to be emphasized that the
greatest severe weather threat, including a tornado or two, will be
in the mountains and valleys. Winds gusting to 60 to 100 mph cannot
be ruled out, especially in the higher elevations of the mountains.

CAPES in the mtns/valleys will be between 1000 - 1500 J/KG and deep
shear will be 60 to 80 knts. SPC has our higher elevations in SLIGHT
risk with hatched area for winds. There is a 2% TOR prob for the
mtns and SLV. the slight risk also includes most of El Paso county.

The overall best forcing will be located over the 4 corners around
18 UTC today (noon local), over the greater Salida/Pikes Peak region
round 21 UTC (3 pm local) and into NE CO at 00 UTC (6 pm local).

For the plains, the greatest threat will be fire weather. Although
we may not technically verify Red Flag conditions (RH values will
likely stay above 15% all of today), the combination of the strong
winds (synoptically gusting to 60 mph, with stronger gusts in
thunderstorm) and drought conditons warrant the Red Flag Warning.
Cloud to ground  lightning strikes will have the potential to cause
new fire starts over all of the region today. Any new fire start
will have the potential to rapidly spread.

Significant amounts of blowing dust are likely today over the
plains.

The strongest storms on the plains will occur along the I-25
corridor (especially El Paso county), with the storms weakening as
you go east.

Given the synoptic situation, There is a good chance that either a
severe thunderstorm or tornado watch will be issued for parts of the
region by late morning or early afternoon.

High winds warnings and Red Flag warnings are already in effect for
parts of the region for today. \/Hodanish

.LONG TERM...(Sunday through Friday)
Issued at 342 AM MDT Sat Jun 6 2020

...Widespread Critical Fire Weather Conditions are Expected Sunday...

Sunday...As the disturbance that affects us for Saturday continues
to propagating into Canada, another upper-level trough is expected
to translate from the Pacific Northwest into the Intermountain West
region. As it does, increasing southwest flow aloft is expected to
keep temperatures relatively hot and usher in much drier air. At the
surface, strong south to southwesterly winds of 25-35 mph with gusts
to around 50 mph are expected to develop by around midday and
continue into the evening. The strong winds and very low relative
humidities will create critical fire weather conditions for much of
the area. Latest guidance continues to indicate a dryline will be
set up near the Kansas border, but the dry air should penetrate far
enough into the eastern most counties to warrant a Red Flag Warning.
Therefore, have not made any changes to the current Red Flag
Warning.

Monday and Tuesday...The upper-level trough is expected to continue
propagating eastward through Colorado and into the Great Plains by
Tuesday evening. Strong south to southwesterly winds are expected
once again Monday as the trough continues to approach the region,
though guidance is indicating that the winds will not be quite as
strong as Sunday. The trough is also expected to send a couple of
cold fronts through the plains on Monday. The initial cold front is
anticipated to propagate across the plains Monday morning, but
uncertainty remains on just how far south this front will make it
before stalling out as lee troughing develops over the southeastern
plains. The front is anticipated to bring a chance for isolated
showers to the Palmer Divide and central mountains through the day
Monday. Additionally, the cold front should aid in keeping relative
humidity values slightly higher across portions of the plains. A
reinforcing front is expected to move through Monday night into
Tuesday, which will bring gusty northerly winds, refreshingly cooler
temperatures to the plains, and continued chances for isolated
showers to the Palmer Divide and central mountains. In fact, it may
become cold enough for a few snow showers across these areas Tuesday
morning. Critical fire weather conditions are still expected for
Monday, but with the uncertainty of just how far south the initial
cold front propagates before it stalls out and the numerous weather
hazards for Saturday and Sunday, will continue to hold off on
issuing any highlights to avoid adding confusion to the already
complicated mix. With the gusty north winds and drier air moving
back in on Tuesday, there is potential for critical fire weather
conditions once again.

Wednesday through Friday...Ridging moves back into the area for the
second half of the week, which is expected to bring an uptick in
temperatures and lighter winds to south central and southeastern
Colorado. An embedded weak disturbance brings a chance for
precipitation to the area on Friday, mainly for the mountains and
high valleys.

.AVIATION...(For the 18Z TAFS through 18Z Sunday afternoon)
Issued at 1118 AM MDT Sat Jun 6 2020

Southerly winds will increase quickly around the start of the TAF
period with wind gusting to 50 kts at all three terminals during
the afternoon. Thunderstorms will be possible through early
evening which could enhance surface wind gusts to around 60 kts
near thunderstorms, along with producing a hail threat. TAFs will
cover this probability through 22z for KALS and through 24z for
both KCOS and KPUB. Thunderstorms should move east of the
terminals by early evening with winds gradually decreasing
overnight. They will increase again Sunday morning with gusts to
around 35-40 kts by the afternoon.  -KT

1037 AM MDT Sat Jun 6 2020

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

.DAY ONE...Today and Tonight

Severe thunderstorms will develop over the mountains, valleys and
portions of the I-25 corridor region today. The greatest severe
weather risk will be straight line winds gusting to 60 to 80 mph.
However, large hail up to 1.5 inches in diameter and even an
isolated tornado will be possible, particularly across the
mountains and San Luis Valley.

The timing of severe thunderstorms today will be from late morning
through mid afternoon across the western mountains and San Luis
Valley. Severe thunderstorms will spread into the eastern
mountains and I-25 corridor after noon and continue through early
evening.

All of south central and southeast Colorado will see strong
southerly winds gusting to between 40 and 60 mph this
afternoon. This will result in strong cross winds on north south
oriented roads and cause poor visibility in blowing dust,
particularly across the plains.

Red Flag Warnings are in effect for all of the southeast plains
today due to a combination of gusty winds, low relative humidity
and dry vegetation. Any cloud to ground lightning strikes over
the region have the potential to ignite new fires, and weather
conditions will be favorable for rapid rates of fire growth and
spread. If you see smoke, immediately call 911. Be prepared to
evacuate quickly if a fire starts near your area.

.DAYS TWO THROUGH SEVEN...Sunday through Friday

Critical fire weather conditions are expected for most of south
central and southeast Colorado on Sunday and Monday as windy
conditions continue into early next week. However, there is some
uncertainty with the areal extent of critical fire weather
conditions on Monday as a cold front could aid in raising relative
humidity values above critical thresholds across northern portions
of the southeast plains. Critical fire weather conditions will
once again be possible Tuesday as gusty north winds and drier air
move back into the region.

Some light snow showers are possible over and near the Palmer Divide
and central mountains Tuesday morning. Later in the week, isolated
thunderstorms are possible on Friday, mainly for the mountains and
high valleys.

.SPOTTER INFORMATION STATEMENT...

Weather conditions that meet reporting criteria for spotters will
be likely across the mountains and interior valleys late this
morning through this afternoon, and across the southeast plains
and this afternoon through early evening.
