SPC 0730Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0154 AM CDT Thu Apr 10 2025 Valid 121200Z - 131200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected on Saturday or Saturday night. ...Central Rockies to the Upper Midwest... A mid-level ridge from the southern High Plains to the Upper Midwest at 12Z Saturday morning will shift east and gradually dampen, as a shortwave trough progresses across the northern Rockies and into MT through early Sunday. Large-scale ascent will strengthen near peak diurnal heating across parts of the central Rockies to the Black Hills. With only scant buoyancy, isolated/short-lived thunderstorms are anticipated amid scattered high-based/low-topped showers. Where deeply mixed thermodynamic profiles exist in eastern WY and western SD, a very isolated strong gust will be possible. Strengthening of the Great Plains LLJ on Saturday night should eventually yield isolated thunder potential across the Mid-MO Valley into the Upper Midwest. With poor-quality moisture return relative to the EML, uninhibited parcels may be rather elevated. The threat for severe hail overnight in this setup appears low. ..Grams.. 04/10/2025
