....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Severe thunderstorms are not expected on Monday.

....Discussion...
A shortwave trough is expected to amplify from the central Rockies
to the south-central High Plains on Monday. Weak surface wave
development is expected across Texas into southern Oklahoma, with a
modest increase in low-level moisture across central/east Texas into
southern Oklahoma in advance of a cold front moving southeastward
across the southern High Plains. Increasing forcing for ascent and
elevated moisture transport should lead to increasing elevated
convection Monday night across north/northeast Texas into southeast
Oklahoma and the ArkLaTex. While a mid-level capping inversion may
tend to persist, updrafts should increasingly reach a sufficient
depth/temperature late Monday night into early Tuesday for at least
isolated thunderstorms. Severe thunderstorms are not currently
expected given access to only weak elevated buoyancy.

Isolated thunderstorms will also be possible late Monday night
across the coastal Pacific Northwest and northern California as weak
buoyancy develops with an upper trough approaching the coast and an
inland-moving frontal band.
