Day 1 Convective Outlook

Valid 220100Z - 221200Z

...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
The risk for thunderstorms appears negligible across the U.S.
tonight.

...01Z Update...
Generally dry and/or stable conditions prevail across much of the
nation.  East of the Rockies, downslope warming has contribute to
some moderation of temperatures across the northern and central
Great Plains.  Otherwise, cold surface ridging remains entrenched
across the southern Great Plains and Gulf Basin through much of the
Atlantic Seaboard and offshore Atlantic waters.

The surface front near the shallow leading edge of this air mass did
shift back inland across the mid/upper Florida Keys and southeastern
Florida coastal areas.  However, models indicate that warm/dry
layers aloft (evident in 22/00Z observed soundings) will suppress
deep convective development rooted within weak boundary-layer
instability, before the front advances back across and offshore of
coastal areas later tonight, in the wake of a developing frontal
wave across the southwestern Atlantic.
