...DISCUSSION...
Upper ridge will gradually flatten over the southwestern US by the
end of the week as heights fall within the base of a progressive
trough that should migrate into the Rockies by day6. In response to
this evolution, higher-PW air mass should begin to advance inland
across TX as lee trough strengthens across the High Plains. Beyond
day6 the ECMWF and GFS begin to diverge in their solutions regarding
the speed/placement of lowering heights across the south-central US.
While instability should increase across the southern Plains,
possibly leading to convection, too much uncertainty exists to
warrant severe probs at this time.
