SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0753 PM CDT Tue Jul 09 2024 Valid 100100Z - 101200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE LOWER OHIO VALLEY... ...SUMMARY... A couple of tornadoes will be possible across the lower Ohio Valley this evening. Isolated strong wind gusts may also occur this evening from southern Kentucky to southern Lake Erie. ...Lower Ohio Valley... The remnants of Tropical Cyclone Beryl are currently located from the far southern Great Lakes southward into the Ohio Valley. A line of strong thunderstorms is ongoing from southern Indiana into west-central Kentucky. A few discrete storms are located ahead of the line further to the east into central Kentucky. The RAP is analyzing a pocket of moderate instability across south-central Kentucky, where MLCAPE is estimated to be in the 2000 to 3000 J/kg range. This will help maintain thunderstorm development this evening. The WSR-88D VWP at Louisville, KY currently has 0-6 km shear around 40 knots, with 0-3 km storm-relative helicity near 370 m2/s2. This shear environment will be favorable for rotating cells with an isolated tornado threat this evening. The threat should gradually shift eastward into east-central Kentucky and southwest Ohio later this evening. A few marginally severe wind gusts will also be possible across the Ohio Valley and far southern Great Lakes this evening into tonight as the remnants of Beryl move northeastward. ..Broyles.. 07/10/2024
