SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0742 PM CDT Wed Jul 10 2024 Valid 110100Z - 111200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM EASTERN PA TO NORTHERN NH... ...SUMMARY... A couple tornadoes along with scattered damaging winds remain possible this evening, over a portion of the Upper Mid-Atlantic States into western New England. ...01Z Update... A broken convective swath, consisting of mainly semi-discrete cells and short-linear clusters, should persist for a couple more hours from parts of the Mid-Atlantic States into western New England. Rich low-level moisture, characterized by low to mid 70s surface dew points, may support a relatively slow decay to convective vigor through late evening. Low-level wind profiles will subside more quickly from south to north tonight. This will yield a spatially diminishing threat away from the surface warm front, especially overnight. In the southeast NE/Lower MO Valley vicinity, the bulk of afternoon convection has waned. But regenerative updrafts along the western portion of the effective composite outflow/front may support an isolated severe hail and marginally severe wind threat for a couple more hours. ..Grams.. 07/11/2024
