Day 2 Convective Outlook
NWS Storm Prediction Center Norman OK
1229 AM CST Fri Jan 21 2022
Valid 221200Z - 231200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Isolated thunderstorms may occur across parts of south Florida and
the Keys on Saturday, but severe thunderstorms currently appear
unlikely.
...Synopsis and Discussion...
A series of shortwave troughs are forecast to progress through
northern stream, reinforcing and deepening the upper troughing
across much of the northeastern CONUS. Within the southern stream, a
shortwave trough initially over the MS Delta region will move
eastward over the central Gulf region and across the FL
Panhandle/northern FL. Father west, an upper low centered over the
Lower CO River Valley will remain largely in place, with only modest
southward motion anticipated.
Relatively progressive upper pattern will help maintain a dry,
continental air mass across the majority of the CONUS. The only
exception is south of a weak front across central and southern FL.
In this region, low to mid 60s dewpoints amid afternoon temperatures
in the 70s may result in enough buoyancy for a few isolated
lightning flashes. Strong mid-level flow will be in place over the
region, supporting moderate bulk shear. However, low-level flow will
be weak and buoyancy will be limited, tempering the overall severe
potential and keeping the severe storm probability very low.
