Day 2 Convective Outlook
NWS Storm Prediction Center Norman OK
1123 PM CST Mon Jan 03 2022
Valid 051200Z - 061200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Isolated thunderstorms may occur over far eastern North Carolina on
Wednesday. Severe thunderstorms are not expected across the
continental United States.
...Synopsis and Discussion...
A large area of cyclonic flow aloft will remain over much of the
central and eastern CONUS on Wednesday, with a leading shortwave
trough moving from the Great Lakes into the Northeast. Behind this
feature, a low-amplitude wave will dive southeast across the Rockies
and into the central Plains producing strong height falls.
Meanwhile, an upper ridge will remain along the West Coast.
At the surface, stable conditions will exist over most of the CONUS,
the exceptions being far eastern NC and southern FL. Weak moisture
return will occur ahead of a cold front along the East Coast during
the day, and MLCAPE on the order of 100-200 J/kg may affect the
Outer Banks of NC. Forecast soundings indicate elevated parcels are
most likely over land, with perhaps isolated cells around Cape
Hatteras. Although deep-layer shear will exceed 40 kt, expected
coverage of storms and weak instability currently preclude low
severe probabilities.
Elsewhere, dry air aloft and a subsidence inversion below 700
suggest only shallow convection along or just off the eastern coast
of FL.
