/00Z TAFS/
A few light showers are affecting areas near the KSOA and KSJT
locations, but should not have any significant impacts. MVFR
ceilings are also affecting the KSOA area. With temperatures
cooling and moisture increasing, see no reason why those low
clouds won't persist into tomorrow. Otherwise, increasing 
moisture should result in low clouds developing tonight across 
the rest of the area, with scattered showers possible late tonight
into tomorrow as well. Winds will become southeast at 5 to 10 mph
later tonight, then south/southwest by tomorrow afternoon. 20

(Tonight and Friday)

A few showers and isolated thunderstorms will be possible mainly 
across northern sections overnight. Precipitation is expected to 
be light through tonight, with most areas seeing 1/10 inch or 
less. Temperatures will be warmer tonight due to extensive cloud 
cover, with lows in the upper 50s and lower 60s.

For Friday, there is a chance of showers and thunderstorms across
West Central Texas due to weak mid to upper level ascent. Highs 
will be in the mid to upper 70s. 


(Fri Night through Thursday)

A heavy rain pattern is possible for West Central Texas Friday 
night and continuing into early next week. The remnants of Sergio 
will bring a good chance of rain to much of West Central Texas 
Friday night into Saturday, especially along and north Interstate 
10. There is also a potential for isolated severe thunderstorms 
during this time. Main threats will be large hail and damaging 

Then both the ECMWF and GFS show a strong cold front moving into 
West Central Texas on Sunday. At the same time, both models show a
developing upper low across Arizona. This will result in strong 
lift across much of the area as moisture from the Gulf of Mexico 
and Pacific is lifted isentropically above the cold dome of high 

Additionally, a large 90-100 knot strong jet streak will be 
moving across the Panhandle Sunday through Monday. This should 
result in strong divergence aloft in the right entrance region of 
this 100 knot jet streak across portions of West Central Texas. 
The main upper trough will also provide additional lift. This 
means there will be a period of prolonged deep lift across West 
Central Texas from Sunday through Tuesday, which will result in 
the potential of additional flooding rainfall. It's still a too 
early to pinpoint the exact areas of heavy rainfall. But we will 
continue to monitor the threat. 

High temperatures will be mostly in the 40s on Monday and lower 
into the upper 30s to near 40 Tuesday morning. Chances of rain 
will continue through Thursday as an upper trough of low pressure 
continues across Baja.
