...discussion...
in the wake of a short wave trough pivoting inland of the british
columbia coast by mid week, medium-range guidance continues to
indicate the gradual development of large-scale ridging across the
much of the intermountain west through great plains and mississippi
valley late this week through next weekend. it appears that a
center of seasonably high mid-level heights will evolve and develop
northeastward, west through north of the four corners, into northern
colorado by the end of the period. prior to and as this occurs,
this may be preceded by the transition of a generally zonal to
broadly cyclonic regime across and east of the northern great plains
through northern and middle atlantic seaboard, but embedded short
wave developments remain rather unclear.
regardless, it still appears that substantive potential for
organized severe thunderstorm development, if any, will largely
remain influenced by sub-synoptic developments yet to evolve, and of
particularly low predictability at this extended time frame.
