.UPDATE...
Issued at 141 AM CDT Tue Jul 15 2025

Recent model runs of the HRRR and other short range models continue
to show heavy rain and thunderstorms moving across the I-10 corridor
this morning. Rainfall totals near 1-2" seem possible along with
locally higher amounts near 3". In fact, some of the more recent
model runs continue to show this activity further north into the
Concho Valley. This is further north than previously thought. Given
recent rainfall across these areas, flash flooding seems likely as
this activity moves through. We will remain under a Moderate to
Slight Risk of excessive rainfall leading to flash flooding. As a
result, the Flood Watch has been extended northward to now include
Tom Green and Concho Counties as well. We have also extended the
watch until 1 PM CDT.

.SHORT TERM...
(Today and tonight)
Issued at 141 AM CDT Tue Jul 15 2025

Complex of showers and thunderstorms from Del Rio area was moving
north into the I-10 corridor and Concho Valley at 6Z. Latest CAMS
weaken the complex by 7 AM this morning, but previous models
continued the storms this morning and into the afternoon. Thus
extended the Flood watch to 18Z. Also, expanded watch to include
Tom Green and Concho counties as soils are saturated there, and
even an inch of rainfall would bring a return of flooding.

Shower and thunderstorm activity end quickly early this evening.
Lows tonight will be in the lower 70s.

.LONG TERM...
(Wednesday through Monday)
Issued at 141 AM CDT Tue Jul 15 2025

Both the ECMWF and the GFS are indicating an end to the unsettled
pattern across the region. High pressure builds aloft by the end of
the week into the weekend. As a result, highs will warm into the
middle to upper 90s. Much drier conditions will remain in place as
this high pressure sets in.

.AVIATION...
(18Z TAFS)
Issued at 1214 PM CDT Tue Jul 15 2025

Main area of rain has broken up early this afternoon, but
scattered convection is expected to redevelop across much of the
area later this afternoon. Hard to tell whether any of this will
be near one of the terminals, so went ahead and ran a PROB30 at
all locations for the afternoon hours. Otherwise, mainly VFR
conditions this afternoon and evening, with some MVFR cigs moving
back into the southern terminals around sunrise Wednesday morning.
South winds will prevail but may be gusty and variable near any
of the storms.
