.Synopsis...
Flood threat continues for portions of Colorado and New Mexico... Isolated
flash and urban flooding possible this weekend for the Lower Mississippi and Lower Ohio Valley...

.Colorado and New Mexico...
Showers and thunderstorms are expected to continue over the San Juan
Mountains and Upper Rio Grande Valley (CO) through this evening, where
recent heavy rainfall has already produced significant flooding impacts
over the past few days. While rainfall totals will be lower than in recent
days, additional rain on saturated soils and full waterways will prolong
flooding concerns. Farther south, flooding of small creeks, streams,
arroyos, and low-lying areas remains possible across portions of
north-central NM where repeated rounds of locally heavy rainfall occur.
Flash flooding should be limited, but isolated instances may still develop,
especially near recently burned areas.

.Lower Mississippi and Lower Ohio Valley...
Periods of locally heavy rainfall may lead to isolated instances of flash
and urban flooding this weekend across portions of the region. Confidence
is low regarding which areas may see hydrologic responses, if any, due to
uncertainties in the placement and magnitude of the QPF. Nonetheless,
antecedent conditions remain very dry, and the progressive nature of the
event will help mitigate widespread hydrologic responses, limiting any
potential flooding impacts to urban and other flood-prone areas.
