Note: A severe weather area depicted in the Day 4-8 period indicates 15%, 30% or higher probability for severe thunderstorms within 25 miles of any point.
|
|
PREDICTABILITY TOO LOW is used to indicate severe storms may be possible based on some model scenarios. However, the location or occurrence of severe storms are in doubt due to: 1) large differences in the deterministic model solutions, 2) large spread in the ensemble guidance, and/or 3) minimal run-to-run continuity.
|
|
POTENTIAL TOO LOW means the threat for a regional area of organized severe storms appears unlikely (i.e., less than 15%) for the forecast day.

...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.
