.SHORT TERM...
(Today through Monday)
Issued at 1254 AM CDT Sun Jul 13 2025

A dangerous risk with the potential of high impact flash flooding
event is unfolding late tonight into Sunday. Various meteorological
features are forecast to come together to create heavy rain rates (2
to 4 inches/hr) leading to flash flooding and rapid river rises. The
complex of storms is likely to slowly push to the southeast from the
San Angelo area as abundant Gulf moisture feeds into the convergence
zone (line of storms). This is a dangerous situation since we
already had a significant heavy rain event last week with soils near
to saturation or at saturation levels. Runoff will take over quickly
making rivers to rise to dangerous levels in addition to flash
flooding across poor drainage and low-lying areas and low water
crossing. Hires models are in good agreement with tonight's heavy
rainfall event and therefore, our confidence is medium to high as
far as occurrence and locations. With that said, higher rainfall
amounts are expected through the Flood Watch period with 2 to 4
inches and isolated 9 to 12 inches possible.

There is a good chance that the Flood Watch gets extended and
expanded on Sunday with new data suggesting for heavy rain to
continue Sunday evening into Monday morning as a mesoscale
convective vortex lingers around the Hill Country. For now, we are
concentrating for the late tonight into Sunday morning period.

MVFR cigs are forecast to prevail across the I-35 corridor terminals
through late this morning. Then VFR cigs are expected for the rest
of today and evening. However, storms are expected to move across the
I-35 sites bringing down cigs and vsbys to MVFR levels this afternoon
and evening. A south to southeast flow is forecast to prevail through
the period. MVFR cigs return overnight across all area airports.
