What forecasters said that day

The local office's own words before this red flag warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Pueblo, CO wrote its last area forecast discussion before this red flag warning went out at May 7, 11:26 AM MDT, 3 hours 19 minutes earlier.

.SHORT TERM...(Today and tonight)
Issued at 347 AM MDT Sun May 7 2023

Key Messages:

1)Critical Fire Weather conditions again this afternoon and evening
for portions of southern Colorado.

Currently...satellite imagery shows increasing mid and high clouds
across western Colorado spreading eastward early this morning.  A
weak surface boundary has backed west across the Plains helping
humidity values recover.  Temperatures are cool, with 40s and 50s
across the Plains, and 40s across the San Luis Valley.

Today...expect another round of critical fire weather conditions for
this afternoon and evening across much of southern Colorado.  Red
Flag Warnings are in place for the San Luis Valley, east into the I-
25 corridor.  Gusty winds, near 35 mph and low humidity values near
10 percent are forecast for this afternoon and evening.  The main
question will be how far east the westerlies mix.  Current model
guidance keeps the strongest winds west of a line from near Colorado
Springs, southeast to near Rocky Ford and Springfield.  If the
westerlies can mix further eastward, elevated fire weather
conditions could be possible further east to near Lamar.  We will
continue to monitor the conditions into this afternoon, but
currently think the going Red Flag highlights look good.

An embedded upper wave in southwesterly flow aloft will move across
north Central Colorado this afternoon.  Weak instability along with
the embedded wave may spark isolated to scattered showers and
thunderstorms, mainly from the La Garita Range, north across the
Central Mountains this afternoon.  A couple of storms may also be
possible over Teller County and the Palmer Divide later this
afternoon.  Lightning and wind gusts to near 40 mph may be possible
with stronger storms.

Afternoon highs today will reach into the 70s to 80s across the
Plains.  Highs across the San Luis Valley will reach the 60s.

Tonight...the upper wave will continue to lift northeast into the
northern Plains allowing for any storms that do develop to quickly
dissipate this evening.  A more robust surface boundary will drop
south across the Plains overnight, turning low level flow
northeasterly.  This will advect moisture back westward across the
Plains, allowing humidity values to recover overnight.  Overnight
lows will fall into the 40s by morning across the Plains, and upper
20s to lower 30s for the San Luis Valley.  Mozley

.LONG TERM...(Monday through Saturday)
Issued at 347 AM MDT Sun May 7 2023

Key Messages:

1) Threat for critical fire weather conditions through mid week,
mainly over the San Luis valley, southeast mountains and southern
I25 corridor.

2) Chances for some strong convection, especially near the Kansas
border, during mid week.

.Monday...Weak high pressure develops behind the departing trough
on Sunday, keeping weak upslope flow over the eastern plains for
much of the day. The weak upslope would tend to keep winds on the
plains from the southeast with slightly higher humidities.
Further west, the dry southwest flow aloft will likely bring
critical fire weather conditions to the San Luis Valley. Currently
looks as if there will be enough mixing for lower humidities over
the eastern mountains and southern interstate 25 corridor. Issued
a fire weather watch for these regions with the greatest chances
for critical fire weather conditions in the San Luis Valley. With
the southerly flow on the plains, there will be the chance for
some high based convection during the afternoon over the Palmer
Divide region.

.Tuesday...Southwest flow aloft increases as a trough moves into
southern California. At the surface, upslope flow increases over
the plains of Colorado. There is a fair amount of low level
moisture over the high plains which could be advected westward
into Colorado. Currently, there is a chance that enough moisture
will exist near the Kansas border for some stronger convection
during the afternoon. The NBM has around 1000 J/kg of CAPE near
KLAA and some of the models suggest the richer moisture making
into the Colorado. Main factors for convection would be the
strength of a cap as well as the lack of any disturbance. Current
grids have isolated convection near the border, which looks good.
However, will have to watch that any convection which develops
could be strong with the higher CAPE and shear. SPC outlooks have
the stronger convection in Kansas, which looks reasonable at this
time. There may also be enough moisture for some convection along
the Palmer Divide with the deeper upslope over northeast Colorado.
Otherwise, critical fire weather conditions are possible with the
best chances over the San Luis Valley, southeast mountains, and
southern I25 corridor.

.Wednesday and Thursday...Models are still struggling with the
timing of the trough as the EC and GEM have a slower solution.
General trends are to have the deeper moisture stay mostly north
of the CWA. One area for increased chances of convection would be
over the Palmer Divide westward in the mountains. Another area of
concern will be near the Kansas border. A dry line/trough will
likely develop over southeast Colorado and move eastward as the
upper trough approaches. Depending on timing of the system, some
stronger convection could develop along the dry line in eastern
Colorado on Wednesday before moving eastward in Kansas. The faster
GFS solution is more favorable for stronger convection with the
forcing and dry line over southeast Colorado Wednesday afternoon
and evening, while the slower EC has less favorable timing with
best forcing overnight Wednesday into Thursday. Most of the
convection will be out of the region Thursday with specifics
depending on the speed of the trough.

.Friday and Saturday...Not a lot of confidence in the specifics.
With the upper low north to northeast of the region Friday,
anticipate westerly flow over the region Friday. Depending on the
speed of the trough, there could be enough instability for some
daytime convection. On Saturday, ensembles and operational models
suggest usplope flow develops bringing moisture westward into
southeast Colorado. Broad upper low over the southwest could
enhance lift. Details are difficult to define at this time, but it
could be the start of a wetter period for southern Colorado.

.AVIATION...(For the 18Z TAFS through 18Z Monday afternoon)
Issued at 1123 AM MDT Sun May 7 2023

VFR conditions are expected at all three TAF sites, KCOS, KPUB, and
KALS for the next 24 hours. Southwesterly winds gusting up to 35kt
are expected at KALS this afternoon, and up to 30kt are expected for
KCOS and KPUB. Winds are expected to weaken after around 02Z this
evening. Mid-level cloud coverage is expected to increase for this
afternoon, with precipitation chances remaining low at all three
sites. Thunderstorms could develop within the vicinity of KCOS this
afternoon, but will likely remain off station over the higher
terrain north and west of the terminal. Gusty and variable outflow
winds up to 40kt are possible near virga and thunderstorms this
afternoon as well, especially in the vicinity of KCOS.
