Valid 231630Z - 241200Z
...NO THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Thunderstorms are not expected today or tonight.
...Synopsis...
A pronounced mid-level trough and associated deep surface low will
continue to progress further into the Atlantic, leading to upper
ridging over the Intermountain West and broad northwest flow across
the central CONUS today. Surface high pressure and an accompanying
continental polar airmass will overspread much of the U.S. east of
the Rockies through the period, limiting thunderstorm potential.
