.DISCUSSION...
Issued at 1130 AM MDT Sat Sep 12 2026

Looks like a gradual ramp up to an active upcoming week with the
best monsoonal pattern we have seen this summer. For this weekend,
we will start out with a weak upper high near the International
Border with some better moisture over the far western areas where
we will have afternoon and early evening storms, focused on the NM
Bootheel and the Gila region moving east through Sierra County.
Very localized heavy rain is the main threat. As the upper high
shifts into the OK/AR area tomorrow and into the Lower Mississippi
River Valley area by Mon, we start setting up a better moisture
push with southeast winds bringing low level moisture from the
gulf and more southerly mid/upper level winds. There is also an
approaching upper trough moving into the west coast. Western zones
will have the best chances for storms, but both GFS and EC showing
outflows pushing east and will likely trigger activity further
east into the evening each day. Temperatures will remain about
5-10 degrees above normal, but the far western zones could be
closer to normal depending on residual cloud cover.

As we go into Tue-Fri, things get more interesting. The
aforementioned upper trough meanders east and lingers around the
area through this timeframe. A good moisture influx continues and
PW`s start to get into the 1.1-1.5" range by the later half of the
week. Storm motions will mainly be under 10kts with a deep more
southerly flow supporting training storms. With all of this in
place some locations will see several days of heavy rain which
could lead to some flash flooding. Things could change if this
trough pushes east quicker, but the upper high to the east will
likely not allow for that. Temperatures will also be dropping and
being closer to normal or even below normal.

P6SM FEW-SCT100-120 SCT-BKN200-250 with isolated to scattered
3-5SM -TSRA BKN050-070 focused near the AZ border and the Gila
region through Sierra County. KTCS is the most likely terminal to
see storms and kept in the PROB30 there. Clouds will gradually

.FIRE WEATHER...
Issued at 1130 AM MDT Sat Sep 12 2026

No fire danger over the upcoming week as moisture gradually
increases. There will be daily storm chances, initially focused
out west but shifting further east as we get into Mon/Tue onward.
Heavy rain will be a threat, especially next week as many areas
will receive daily rainfall. Temperatures will start out above
normal but start to drop to near or even below normal by the end
of next week. Vent rates the next couple of days will be fair to
good.
