...DISCUSSION...
The upper-low over New England will gradually drift away from the
U.S. as an upper ridge builds west of the Rockies this weekend into
early next week. Surface troughing will persist across the Plains
states, with adequate low-level moisture remaining in place to
support scattered thunderstorms. At the moment, it appears that any
severe risk will be sparse at best. As the upper ridge persists, a
positively tilted upper trough will rapidly translate from Canada
into the MS Valley during the middle of next week, accompanied by a
progressive surface cold front. This cold front will bring a cool,
stable airmass to much of the northern and central Plains into the
MS Valley, reducing thunderstorm potential. Strong storms could
occur immediately ahead of the surface cold front around Day
8/Wednesday, though questions surrounding the placement and timing
of this front preclude the introduction of severe probabilities at
this time.
