...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Non-severe thunderstorm development will be possible across parts of
the southern Plains from Tuesday afternoon through Tuesday night.

...DISCUSSION...
An upper-level low will retrograde southwestward across southern
California on Tuesday as zonal mid-level flow remains from the
southern Plains to the Eastern Seaboard. At the surface, a cold
front will advance southward across south-central and east Texas.
Surface heating and increasing low-level convergence along the front
could be enough for isolated thunderstorm development Tuesday
afternoon, mainly in south-central Texas. Instability will likely be
insufficient for a severe threat. Elsewhere across the continental
United States, thunderstorms are not expected Tuesday or Tuesday
night.
