Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0247 PM CDT Wed Apr 09 2025 Valid 092000Z - 101200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated thunderstorms remain possible through tonight from parts of the northern/central Plains into the Midwest and Ohio Valley and eastern FL. Severe thunderstorms are not expected. ...20z Update... Only minor changes were made to the thunder areas across parts of NE and MT for the latest guidance and ongoing storms. Severe thunderstorms are unlikely, see the prior discussion. ..Lyons.. 04/09/2025 .PREV DISCUSSION... /ISSUED 1115 AM CDT Wed Apr 09 2025/ ...Synopsis and Discussion... Multiple low-amplitude, mid-level shortwave troughs are forecast to develop east-southeastward today and tonight from parts of the northern/central Plains into the Midwest and OH Valley. Rather meager/shallow low-level moisture will tend to limit thunderstorm coverage and intensity across these regions. Even so, sufficient large-scale ascent and weak MUCAPE may still support isolated convection capable of producing lightning through the period. Occasional strong/gusty winds may occur with high-based thunderstorms across parts of SD/NE this afternoon, but organized severe thunderstorms are not forecast.
