Areas affected...south-central NM

Concerning...Heavy rainfall...Flash flooding possible

Valid 060142Z - 060500Z

Summary...A localized risk of flash flooding will linger for
another few hours before a loss of instability allows convection
to fade. Rainfall totals of an additional inch or two will be
possible through 06Z.

Discussion...Radar imagery and surface observations at 0115Z
showed scattered thunderstorms over central NM, focused along the
leading edge of a combined outflow/cold frontal boundary sweeping
south and southwest across the state. Remaining instability via
the 00Z ABQ sounding and SPC mesoanalysis page from 01Z indicated
MLCAPE up to 500 J/kg with a pocket or two in excess of 500 J/kg
along with precipitable water values between 0.8 and 0.9 inches.
MRMS rainfall estimates continued to indicate high short term
rainfall rates of 0.5 to 1 inch in 15-30 minutes with the
strongest cores.

Thunderstorms are expected to follow the path of the outflow
boundary toward the south and west with continued but isolated
high rainfall rates maintaining a limited flash flood threat
across the region. However, if sufficient instability can survive
as outflow reaches the Sacramento Mountains, a few sensitive burn
scars could be impacted with a quick 0.5 to 1.5 inches of rain.
Therefore, while the flash flood threat remains in the short term,
it is expected to remain rather localized and should dissipate
beyond ~04/05Z.
