Day 2 Convective Outlook

Valid 031200Z - 041200Z


Isolated thunderstorms may occur Wednesday across parts of western
Colorado and vicinity. Severe thunderstorms are not expected.

...Synopsis and Discussion...
A large-scale upper trough will progress eastward across much of the
western/central CONUS on Wednesday. Strong ascent preceding this
feature coupled with modest diurnal heating and cooling mid-level
temperatures should support the development of weak instability
(MUCAPE up to 300 J/kg) Wednesday afternoon across western CO and
vicinity. Even though low-level moisture is expected to remain very
limited, it appears that the modest instability may extend through a
sufficient vertical depth to support charge separation and isolated
lighting flashes. East of the Rockies, an upper ridge is forecast to
move eastward from the Plains and Upper Midwest to the eastern CONUS
through the period. Low-level moisture return across the
southern/central Plains in advance of the approaching upper trough
is expected to remain insufficient to support any meaningful
thunderstorm potential.
