....DISCUSSION...
An amplified yet progressive pattern will persist through the
Sat/D4-Wed/D8 period. Ensemble members are in reasonable agreement
through Mon/D6, showing an upper low over the Great Lakes gradually
weakening with rising heights across the East. Offshore surface
winds will remain over the Atlantic and Gulf Coasts through Mon/D6
night, with little if any instability present. Models do indicate a
shortwave trough may move from the Southwest into TX and then across
the Gulf Coast States around Tue/D7. Regardless of the exact timing
of this low-amplitude wave, any appreciable instability will remain
over the Gulf of Mexico, with only rain and weak thunderstorms
affecting land. As such, severe weather is unlikely through the
period.
