...Flash and urban flooding possible for the Southwest through tomorrow...
...Flood threat developing over the Southern Plains into the Ozarks
tomorrow...

.Southwest...
Multiple rounds of showers and thunderstorms are expected over the CA/NV
line into central AZ and NM through tonight and into the early
weekend, bringing the potential of isolated flooding to the region. The
greatest threat of impacts will be in and around recently burned areas,
where flash flooding and debris flows may occur if heavy rainfall moves
over. Rainfall should start to move east of the region tomorrow night,
bringing drier conditions to the area.

.Southern Plains into the Ozarks...
Moderate to heavy rainfall starting tomorrow will bring the potential for
locally considerable flash and urban flooding to the TX Hill Country
region through Thursday. Additionally, this rainfall will prime the region
ahead of further rounds of rainfall which are expected to manifest
beginning in the late weekend on Sunday and continue into early next week.
Initially, antecedent conditions will be dry, resulting in a flooding
threat from mostly isolated heavy rainfall. However, as the rainfall
saturates what little soil overlies certain areas of central TX this may
increase the potential for flash, urban, and small stream flooding along
with bringing the potential for isolated river flooding. Areas that will
need to be watched closest for flood impact potential over the next 6 days
will be central Texas up to the OK line.
