...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
The risk for thunderstorms appears negligible across the U.S.
Wednesday through Wednesday night.

...Discussion...
Models indicate that an increasingly prominent high may build once
again across and north of the Aleutians vicinity, but it appears
that there will be little change to the downstream flow across the
mid-latitude eastern Pacific into western North America, through at
least this period.  Downstream, there is substantive spread in the
model output concerning the subsequent evolution of short wave
troughing initially digging across the Midwest at the outset of the
period, and another notable perturbation digging toward the Great
Lakes region, after emerging from the southern Hudson Bay vicinity.
Regardless, larger-scale mid/upper troughing to the east of the
Rockies will be reinforced, and related surface developments are not
likely to promote a southerly return flow off the Gulf Basin, where
boundary-layer modification in the wake of the prior front will only
be gradually underway.
