valid 291200z - 301200z
...no severe thunderstorm areas forecast...
...summary...
isolated thunderstorms are possible across the southern florida
peninsula and portions of southern arizona/southwest new mexico
sunday afternoon and evening. severe thunderstorms are not expected.
...synopsis...
quasi-zonal flow is forecast across the conus on sunday while a
mostly dry and stable boundary layer will persist, limiting
thunderstorm potential. the exception will be across portions of the
fl peninsula and keys. a seasonally moist airmass will persist near
a decaying frontal boundary. strong heating will support weak
destabilization and isolated thunderstorms may develop along sea
breeze interactions or the residual frontal boundary. a few
thunderstorms also will be possible across the far southern
az/southwest nm vicinity where steep midlevel lapse rates atop
warm/moist advection in lower levels will support sufficient
destabilization. a weak shortwave impulse will migrate across the
region during the late afternoon/evening and could provide enough
ascent for a few thunderstorms. severe storms are not expected.
