Valid 261300Z - 271200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Organized severe storms are not expected across the continental U.S.
today.

...Synopsis...
An expansive upper-level trough will persist across the eastern
CONUS today, where a cool, dry airmass and high pressure
will be prevalent and limit thunderstorm potential aside from
Florida. Monsoon-related scattered thunderstorms will be common
across much of the non-coastal West.

...Southern Arizona/Lower Colorado River Valley...
A northward-moving mid-level impulse/MCV will spread from the Lower
Colorado River Valley/northern Arizona this morning into Utah,
allowing for subsequent clearing/heating across southern Arizona
toward the Lower Colorado River Valley. Thunderstorms will again
develop and increase this afternoon especially in vicinity of higher
terrain. A few instances of strong thunderstorm winds/wet
microbursts could occur regionally this afternoon into evening, but
the overall potential is expected to remain quite isolated and
marginal overall.
