.DISCUSSION...
Issued at 945 AM MDT Sat Sep 13 2025
Today`s the big day of the forecast period with a good chance for
scattered to numerous storms, with some having the potential to
become severe. Showers and thunderstorms are ongoing early this
morning, but activity will just continue to ramp up through this
afternoon. The area is primed for strong storms this afternoon. An
upper trough will swing through the area today acting as the
major lifting mechanism for storms. RAP forecasted SBCAPEs are
1500-3000J/kg this afternoon coupled with plenty of wind shear
needed for storm organization. 0-6km shear will continue to
increase as the trough progresses eastward with values upwards of
30-45kts. Hodographs still look to take on this straight sort of
look which promotes splitting supercells. In addition, the area
has plenty of moisture with PW values above normal for this time
of year (1.1"-1.4"). The SPC does have a large majority of the
area under a Marginal Risk (level 1/5) encompassing a low threat
(5%) for severe wind and hail. There is a very low chance for
tornadoes in the Sacramento Mtns area (2% risk). In addition,
flooding is possible but not widely expected this afternoon.
Storms will be efficient rain makers but the added wind shear will
allow storms to progress away from one area. One way we could get
flooding is if storms start training (raining over an area
multiple times).
Later this evening the trough sweeps out the moisture and good
dynamics further to the east allowing for Sunday to be much
quieter and drier. Perhaps some lingering moisture is left in
southern Hudspeth which could fuel a few showers/t-storms but
largely the remainder of the area will stay dry. Moisture from the
south attempts to push northward heading into Sunday but looks
like the best of the moisture is along the Int`l Border which
would be the best shot for storms if there`s a lifting mechanism.
Some moisture gets pulled up to the area on Tuesday but high
pressure looks to rebuild over AZ/Vegas/SoCal area, shifting
recycled moisture over the area Wednesday and onward. So
basically, the work week can be described as low end t-storm
chances each day.

remain strong to damaging wind gusts, large hail, frequent
lightning. Any direct hits to terminals will result in brief and
lcl MVFR/IFR cigs/vsbys. Activity is expected to diminish aft

.FIRE WEATHER...
Issued at 945 AM MDT Sat Sep 13 2025
Low fire danger for the week ahead as min RH values stay above
critical thresholds (lowlands: 20-35%, mountains: 35-60%). 20 foot
winds also stay below critical thresholds, generally 4-8 mph each
afternoon becoming calm and light overnight. Today will be the
last day for good areawide rain chances. Tomorrow and maybe into
Monday will be much quieter and drier with the best chances for
rain being along the Int`l Border. Tuesday and onward will
feature low end thunderstorm chances each afternoon with scattered
storms over the area mountains and isolated storms in the
lowlands.
