.DISCUSSION...
Issued at 154 PM MDT Mon Jun 23 2025

Monsoon moisture will continue to move into southern New Mexico
and west Texas tonight into Tuesday. Tropical moisture will be
forced north due to flow between an upper level trough over
California and a dome of high pressure over the Mid-Atlantic.
Moisture levels should peak Tuesday into Wednesday before
gradually decreasing across the region.

The main concerns will be flash flooding from heavy rainfall that
has a moderate risk (40% chance) of occurring for areas just east
of I-25 towards White Sands/Sacramento Mtns northward through
much of central New Mexico. Precipitable water values are expected
to be around 1.5 inches on Tuesday which is about the 99th
percentile of climatology. This along with ample moisture
transport should support widespread convection and depending upon
the rain rates - lead to flash flooding. Hi-res models seem to
point to the 6PM Tuesday to midnight time frame as the best
chances of thunderstorms capable of heavy rainfall and flooding.
Flash flood watches have been expanded into the Rio Grande Valley
and El Paso metro areas for these reasons along with lining up
with favorable large scale ascent from upper level flow. One area
of concern will be the Gila Forrest region as it will be on the
edge of a lot of the higher moisture. If moisture increases more
in these areas then the flood watch may need to be modified to
include these areas. The Trout fire burn scar will be closely
watched for convection and resulting rain rates as it will not
take much rain to cause flash flooding on the burn scar.

Given all these concerns there is another scenario that could
play out that has happened before with monsoon moisture surges
like this. Mid level moisture and cloud cover could be more
substantial and limit daytime heating and therefore instability.
This could lead to clusters of storms producing moderate rain
which could still be an issue but may take more time for any kind
of flood response. This type of scenario is more ideal for soaking
rains into the ground but it will limit how much precipitation
falls. If there are more breaks in cloud cover and more
instability for storms to develop stronger updrafts and therefore
higher rain rates resulting then flooding becomes a much bigger
concern.

.AVIATION...
(00Z TAFS)
Issued at 552 PM MDT Mon Jun 23 2025

Increasing BKN080 BKN200. Scattered BKN-OVC050CB -TSRA, mainly
east of the Rio Grande Valley, but developing to the west over the
next several hours. Isolated OVC040CB 1-3SM TSRA with wind gusts
of 35-45 knots. Thunderstorms mostly dissipating by around 06Z but
showers continuing through most of the night. Thunderstorms
developing again after 18Z.

.FIRE WEATHER...
Issued at 154 PM MDT Mon Jun 23 2025

Overall fire weather concerns are trending down due to an influx
of monsoon moisture into the region. Shower and thunderstorm
activity should increase Tuesday with the best chances of storms
Tuesday evening/night east of the Gila towards the Rio Grand
Valley. Trout fire burn scar will be on the edge of the area of
highest probability for heavy rainfall so it will be closely
monitored. Highest chances of any flooding should peak during this
time with thunderstorm activity decreasing in coverage through
the end of the week. Key point to remember with regards to the
Trout Fire burn scar is that it will not take much rainfall to
cause flooding and debris flows. Showers and storms moving over
some of the same areas will make them more prone to flooding
impacts with more runoff.

...OUTFLOW FROM THUNDERSTORMS OVER NORTHERN CHIHUAHUA WILL BRING
GUSTY WINDS, BLOWING DUST, AND MAY TRIGGER THUNDERSTORM DEVELOPMENT
OVER THE EL PASO METRO AREA THROUGH 8 PM...

At 711 PM MDT, strong thunderstorms over north-central Chihuahua
have produced an outflow boundary that is moving towards Santa
Teresa and El Paso from the west-southwest. Expect wind gusts of 35
to 45 mph as the outflow pushes through, along with blowing dust.
Visibility will be reduced to around 1 to 3 miles.

This outflow will modify the air mass across the area, and may
finally trigger thunderstorm development over southern Dona Ana and
western El Paso Counties in the next hour or two.

HAZARD...Wind gusts up to 45 mph.

SOURCE...Radar indicated.

IMPACT...Gusty winds could knock down tree limbs and blow around
         unsecured objects.

Locations impacted include...
El Paso, Santa Teresa, Sunland Park, Chaparral, Anthony, Vado,
Canutillo, Anthony Gap, Berino, Vinton, San Miguel, Westway, Fort
Bliss, Mesquite, and Chamberino.

This includes the following highways...
 Interstate 10 in New Mexico between mile markers 149 and 164.
 Interstate 10 in Texas between mile markers 1 and 37.

PRECAUTIONARY/PREPAREDNESS ACTIONS...
