T.C. Isaias may still be affecting portions of New England early on
D4/Wednesday, though it should quickly move into the Canadian
Maritimes as the primary upper trough begins to move northeastward
away from the eastern CONUS. The persistent upper ridge over the
West should continue to deamplify and shift slowly eastward,
becoming centered over the southern Plains by the weekend. Aside from any lingering threat associated with Isaias and the
departing upper trough over New England on D4/Wednesday, any
organized severe threat during the extended range period will likely
be tied to a persistent northwesterly flow regime over the
Plains/Midwest through the end of the week, or perhaps with
progressive northern-stream shortwave troughs affecting the northern
Plains by the weekend. Predictability remains much too low to
delineate 15% areas for any specific threat at this time.
