Day 1 Convective Outlook

Valid 231630Z - 241200Z
...NO THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not expected today or tonight.
...Synopsis/Discussion...
A progressive but amplified large-scale pattern will continue,
highlighted by an amplifying upper trough over the Great
Basin/Rockies and an eastward-building upper ridge over the Midwest
and Great Lakes. The general prevalence of dry/stable conditions
will likely preclude thunderstorms across the CONUS. One potential
exception for a couple of lightning flashes might be tonight across
southern/eastern Arizona and the Four Corners area, although
thermodynamic profiles will be quite marginal and thunderstorm
probabilities are expected to remain very low (below 10 percent).
