Day 1 Convective Outlook

1220 AM CDT Fri Apr 05 2024



Valid 051200Z - 061200Z



...NO SEVERE THUNDERSTORM AREAS FORECAST...



...SUMMARY...

Severe thunderstorms are not expected today or tonight.



...Synopsis...

A deep upper-level trough will move eastward across the western

CONUS today into tonight, with a basal mid/upper-level jet maximum

forecast to impinge on the southern Rockies and eventually the

southern High Plains by the end of the period. An expansive surface

cyclone is forecast to consolidate across parts of the

central/northern Rockies and High Plains through the period.

Low-level moisture will remain sparse, but cold temperatures aloft

and favorable ascent will support thunderstorm potential across

parts of the Southwest, and also the northern Rockies and High

Plains. Weak instability should generally limit the severe threat,

but a strong storm or two capable of producing small hail and gusty

winds will be possible across parts of MT/WY. 



Across the East, dry and stable post-frontal conditions will

generally limit thunderstorm potential, as a deep cyclone meanders

near the northern New England coast.
