Day 1 Convective Outlook

1128 PM CST Tue Jan 27 2026
Valid 281200Z - 291200Z
...NO THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Thunderstorms are not forecast for today.
...Synopsis...
A relatively stable pattern will exist across the CONUS today, with
high pressure affecting most areas. A deep upper low will remain
over Ontario, with broad cyclonic flow aloft encompassing most of
eastern Canada and the USA. With high pressure over land, offshore
flow will keep appreciable low-level moisture well offshore from
Cuba toward the Turks and Caicos.
Precipitation will be possible in association with a shortwave
trough moving across the Great Basin during the day and across the
central and northern Rockies. However, little to no instability is
forecast, and as such thunderstorms appear unlikely.
