...DISCUSSION...
Medium-range guidance is in reasonable agreement that upper ridging
west of the Rockies will persist into next weekend while a series of
shortwave troughs contribute to broad upper troughing across the
central and eastern CONUS. This will result in generally
above-average temperatures along and west of the Rockies while
below-average temperatures exist elsewhere. There is some potential
for a cold front resulting from one of the shortwave troughs to
interact with a moderately moist and unstable airmass supportive of
strong thunderstorms. However, low consistency within the guidance
currently precludes much confidence in that scenario.
