...DISCUSSION...
For much of the extended period, a deep upper low and expansive
trough will exist over eastern Canada, with moderate northwest flow
across the central and eastern CONUS with various embedded waves. A
cold front will be located roughly along the Gulf Coast on
Sunday/D4, with areas of rain and thunderstorms from eastern TX
toward the northern Gulf Coast and across northern FL. High pressure
will keep the quality low-level moisture primarily offshore, but
return flow into the southern Plains is forecast from around
Wednesday/D7 and beyond as a potential upper trough develops over
the western CONUS. As such, low severe potential is forecast for
most of the D4-8 period, with perhaps increasing potential by D8 or
beyond as the large northeastern trough dwindles.
