SPC Jul 24, 2022 0730 UTC Day 3 Severe Thunderstorm Outlook

SPC 0730Z Day 3 Outlook Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0234 AM CDT Sun Jul 24 2022 Valid 261200Z - 271200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM THE MID-ATLANTIC WEST INTO THE LOWER MISSOURI VALLEY... ...SUMMARY... Severe thunderstorms will be possible Tuesday from the mid-Atlantic region west to portions of the central Plains. Damaging gusts will be the primary severe hazard. ...Mid-Atlantic west to lower Missouri Valley... A front, reinforced by convective outflows, will extend from the mid-Atlantic coast west into the central Plains Tuesday afternoon. As an upper-level low over Ontario Province moves south, some increase in westerly mid-level flow will occur in the vicinity of the front resulting in effective shear of 30-35 kts. A very moist air mass will remain in place with surface dew points generally in the 70s, supporting moderate/pockets of strong buoyancy by afternoon. Thunderstorms developing in the vicinity of the front will pose a risk for damaging downburst winds, aided by steep low-level lapse rates in areas with more substantial heating. The severe threat should generally diminish during the late evening. ..Bunting.. 07/24/2022 Read more CHECK UPDATE ZOOM GRAPHIC
