Valid 281200Z - 021200Z
Guidance has come into better agreement regarding the upper pattern
through much of next week. Current expectation is for the upper flow
across the CONUS to trend more zonal on D4/Wednesday before a
building ridge over the western CONUS slowly amplifies the pattern
on D5/Thursday and D6/Friday.
Favorable low-level moisture is forecast to return across the
central Plains ahead of an approaching cold front on D5/Thursday.
Thunderstorms are possible along the front on D5/Thursday and
D6/Friday but more run-to-run and model-to-model consistency is
still needed before confidence in the location and coverage of
severe thunderstorms is high enough to delineate any areas.
