Day 2 Convective Outlook
NWS Storm Prediction Center Norman OK
1202 AM CST Sat Feb 25 2017
Valid 261200Z - 271200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
No severe weather is forecast across the Lower 48 states on Sunday
and Sunday night.
A shortwave trough initially over southern CA will quickly move
eastward into AR and deamplify as an upstream disturbance moves
southeastward from the eastern Pacific into the OR/ID/NV vicinity.
A large area of surface high pressure located over the TN VAlley and
southern Appalachians will slide east as weak low pressure remains
situated over the southern High Plains. Southerly low-level return
flow of moisture into eastern TX will result in gradual
destabilization by dark as a low-level jet over the ArkLaTex
strengthens and veers into the Lower MS Valley late. A few clusters
of weak thunderstorms are possible after dark in association with
the warm-air-advection regime. Elsewhere, a few thunderstorms are
possible over primarily western OR.
