Day 4-8 Convective Outlook
NWS Storm Prediction Center Norman OK
0336 AM CST Fri Jan 12 2024

Valid 151200Z - 201200Z

....DISCUSSION...
Upper-level mean troughing will persist across much of the CONUS
during the Day 4-8 period. At least one reinforcing surge of cold,
arctic air associated with this pattern will maintain a dry and/or
stable airmass for much of the U.S., and thunderstorm chances are
expected to be low. Some modest Gulf return flow may occur near the
end of the period in the Day 7/8-Thu/Fri time period as an upper
ridge builds over the West and a shortwave impulse migrates east
from the High Plains to the Southeast. However, quality low-level
moisture will likely remain offshore in the absence of stronger
surface cyclogenesis, precluding severe thunderstorm potential.
