Day 1 Convective Outlook

0647 PM CST Sun Jan 14 2018
Valid 150100Z - 151200Z
...NO THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Thunderstorms are not expected across the U.S. through tonight.
...DISCUSSION...
A large-scale upper-level trough will remain across the eastern
two-thirds of the nation tonight as an upper-level low moves south
southeastward into the upper Mississippi Valley. At the surface,
high pressure will be entrenched across the eastern U.S. as another
cold front moves southeastward across the Great Plains. As a result,
a dry airmass will remain in place across most of the CONUS limiting
the potential for thunderstorm development through early Monday
morning.
