....DISCUSSION...
Forecast guidance is in relatively good agreement that the eastern
CONUS Rex Block in place at the beginning of the period (D4/Sunday)
will break down by D6/Tuesday as the upper low moves off the
Southeast coast. A weak upper flow regime is anticipated across the
central and eastern CONUS after the blocking breaks down through the
remainder of the extended period.

The repeated pattern of afternoon/evening thunderstorms across the
High Plains is expected to continue on D4/Sunday and D5/Monday but
will likely end when the blocking ends. Severe potential from
D6/Tuesday into D8/Thursday appears low given generally weak upper
flow and lack of any notable synoptic features.

...Mosier.. 05/25/2023
