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.
