12AM Day 2 Convective Outlook for Sunday, October 12. NO SEVERE THUNDERSTORM AREAS FORECAST
SUMMARY
A severe threat is not expected to develop across the U.S. Sunday or Sunday night.
DISCUSSION
At mid-levels, a low will move northeastward along the southern Atlantic Seaboard on Sunday, as a ridge remains in place over the Ozarks and mid Mississippi Valley. A shortwave trough will move northeastward from the central Rockies into the northern Plains. Thunderstorms will be possible near the eastern seaboard low and ahead of the north-central U.S. trough. Instability is forecast to remain weak in these two areas, suggesting that a severe threat will be unlikely. Additional non-severe storms will develop in parts of the Desert Southwest and southern High Plains. Elsewhere across the continental U.S., no severe threat is expected to develop Sunday or Sunday night.
