What forecasters said that day

The local office's own words before this river flood 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 river flood warning went out at May 11, 12:23 PM MDT, 2 hours 24 minutes earlier.

Area forecast discussion, May 11, 12:23 PM MDT, 2 hours 24 minutes before
Area Forecast Discussion
National Weather Service Pueblo CO
1223 PM MDT Thu May 11 2023

.SHORT TERM...(Today and tonight)
Issued at 342 AM MDT Thu May 11 2023

Key Messages:

1) Upper low tracks across the area today, with widespread
   showers and thunderstorms expected.

2) Strong/severe storms possible over the plains north of the
   Arkansas River from mid morning into mid-afternoon.

3) Locally heavy rainfall possible today, mainly across El Paso
   County, some heavy snow likely over the higher peaks of the
   central mountains and Pikes Peak.

Upper low over nrn New Mexico this morning will rotate slowly
northward across Colorado today, while surface low near Trinidad
this morning lifts into nwrn KS by late afternoon. Significant wave
of showers/thunderstorms was lifting northward through the plains
early this morning, while dry slot on water vapor energy over
nern NM was pushing into extreme sern CO as of 330 am. As a
result, suspect we'll see a brief lull in precip over the plains
through sunrise, before main round of upward motion moves across
from mid-morning through mid-afternoon, sparking another wave of
thunderstorms, especially east of I-25. Plenty of shear for severe
storms on the plains, but with CAPE rather limited (only 500-900
J/KG), environment may not support sustained, persistent updrafts,
with storm mode trending toward more low topped marginal hail/wind
producers. Farther west, mountains and El Paso County may not see
much of a break in precip this morning, with widespread showers and
thunderstorms persisting. By afternoon, as low lifts north, wrap
around band of precip dives south along I-25, with HRRR showing
heavy QPF (1-2 inches) from Colorado Springs south through Pueblo,
while various other solutions show much less in the way of precip.
Leaned drier than the HRRR at most locations, especially south of El
Paso County, as developing n-nw downslope winds may at least take
a bite out of precip amounts. Will need to monitor areas in El Paso
County for enhanced flash flood risk today, as some pockets of
locally heavy rain are likely, though no flood watch issued yet, as
most locations can still take another couple inches. Snow level
hangs out in the 9-10k range through the day, with several inches of
accumulation likely over the higher peaks of the central mountains
and near the summit of Pikes Peak.

Tonight, precip slowly ends from south to north, with HRRR again
looking the wettest and slowest to end things. Followed more of a
NAM/GFS blend, suggesting showers should end over all but Teller
County/central mountains/Palmer Divide by midnight, with slow
clearing toward morning all locations.

.LONG TERM...(Friday through Wednesday)
Issued at 342 AM MDT Thu May 11 2023

Key Messages:

1) Unsettled and Cool.

Two things stand out in the long term. First, flow aloft will become
quite weak as a high amplitude ridge builds over the western United
States. However, embedded within this building ridge, weak
troughiness will linger through early next week over our fcst area.
Second, moisture is forecast to linger over the region through this
period which will keep a good chance of diurnal showers and
thunderstorms over the region. Overall, this pattern will keep the
region cooler and wetter than normal through mid week. Temps may not
hit 80 on the plains until mid/late week next week.

Given the lack of flow aloft, the severe weather threat will be nil,
but the amount of thunder will likely be above normal during this
period due to the persistent moisture. Burn scar flooding
concerns will likely be on the increase. \/Hodanish

.AVIATION...(For the 18Z TAFS through 18Z Friday afternoon)
Issued at 1218 PM MDT Thu May 11 2023

Mainly VFR conditions expected at COS, PUB and ALS over the next
24 hours, as upper low continues to lift north and east across
