Day 1 Convective Outlook 
NWS Storm Prediction Center Norman OK
1156 PM CDT Fri Apr 08 2022

Valid 091200Z - 101200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
The severe thunderstorm threat is expected to remain low today.

...Synopsis...
A deep upper trough over the eastern CONUS is forecast to move
eastward today, as an upstream trough begins to amplify over
portions of the central/northern Rockies and adjacent High Plains by
early Sunday morning. A surface low will move across portions of New
England during the day, while a stronger cyclone deepens over the
central High Plains in response to the amplifying upper trough.
Moisture will remain quite limited across the CONUS, resulting in
generally sparse coverage of thunderstorms and low severe potential.

...New England...
Despite limited low-level moisture (dewpoints generally in the upper
30s to low 40s F), steep lapse rates and cold temperatures aloft
will support the potential for isolated to widely scattered
thunderstorms as the surface low and attendant cold front move
eastward across the region. Small hail and locally gusty winds may
acco*pany the stronger convective elements, but the severe threat is
expected to remain low due to very limited buoyancy.

...Central Rockies/High Plains...
Weak convection may develop across portions of the central Rockies
and adjacent High Plains this afternoon/evening, as the upper-level
trough amplifies across the region. Inverted-V profiles will support
the potential for locally strong/gusty winds across the lower
elevations, but convection is expected to remain too weak and
disorganized for an appreciable severe risk.
