SPC Aug 1, 2022 0730 UTC Day 3 Severe Thunderstorm Outlook

SPC 0730Z Day 3 Outlook Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0230 AM CDT Mon Aug 01 2022 Valid 031200Z - 041200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM PARTS OF THE LOWER MISSOURI VALLEY NORTHEASTWARD INTO LOWER MICHIGAN... ...SUMMARY... Thunderstorms associated with marginally severe winds and hail will be possible on Wednesday from parts of the lower Missouri valley northeastward into the Great Lakes region. ...Lower Missouri Valley/Mid Mississippi Valley/Great Lakes... An upper-level trough will move eastward into the mid to upper Mississippi Valley on Wednesday, as an associated cold front advances southeastward across the upper Midwest. Ahead of the front, thunderstorm development is expected to take place near a pre-frontal trough during the day from the lower Missouri Valley northeastward into lower Michigan. Along the pre-frontal trough, surface dewpoints from the mid 60s to lower 70s F, should enable moderate instability to develop by afternoon. In addition to moderate instability, 0-6 km shear is forecast to be generally between 25 and 35 knots along much of the front. This combined with steep low-level lapse rates should be sufficient for a marginal wind-damage threat. A few of the stronger updrafts could also have hail. ..Broyles.. 08/01/2022 Read more CHECK UPDATE ZOOM GRAPHIC
