Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
1026 AM CST Sat Jan 22 2022
Valid 221630Z - 231200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Isolated lightning flashes may occur late today into tonight across
parts of Arizona.
...Synopsis...
A surface cold front will continue to move southeastward across/off
the southeast FL coast and Keys during the day, with the primary
threat for thunderstorms focused along the wind shift across the FL
Straits and just off the southeast FL coast. Farther west, a closed
midlevel low will continue to drift southeastward over southwest
AZ/Sonora through Sunday morning. Relatively cool midlevel
temperatures and sufficiently steep midlevel lapse rates, along with
a gradual increase in low-midlevel moisture, could result in just
enough buoyancy for isolated lightning flashes by late today into
tonight within the arc of what is now shallow/midlevel convection
from the Rim into south central AZ.
