Day 3 Convective Outlook
NWS Storm Prediction Center Norman OK
0215 AM CDT Wed Apr 10 2024

Valid 121200Z - 131200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not forecast on Friday.

...East...
Deep surface cyclone near Lake Huron at 12Z Friday should occlude
and slowly weaken as it continues northeastward into western Quebec.
The arcing occluded front across parts of the Northeast may be a
focus for low-topped convection during the late morning to early
afternoon. Surface-based destabilization appears to be rather
limited, but its plausible that scant to meager buoyancy might
develop over the eastern NY vicinity. Low to deep-layer wind
profiles are conditionally favorable for organized updrafts and this
corridor will need to be monitored in later outlooks for a potential
cat 1-MRGL risk highlight.

...West...
An amplified shortwave trough will approach but remain west of the
CA coast through 12Z Saturday. While the bulk of PW increase will
largely be confined to parts of CA and the OR Pacific Coast, modest
moistening should occur within the deep-layer southwesterly flow
regime, west of the mid-level ridge that will become centered across
the High Plains. Scant to meager surface-based buoyancy is expected
by Friday afternoon and this should support isolated to scattered
high-based, low-topped thunderstorms from the Sierra NV across the
northern Rockies. A very isolated severe wind gust is possible given
the steep lapse-rate environment, but an organized severe threat
appears unlikely.
