Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1227 AM CDT Mon Apr 14 2025 Valid 151200Z - 161200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected on Tuesday or Tuesday night. ...Northeast... Sporadic, low-topped thunderstorms may develop towards midday through the afternoon within a post-frontal regime as 500-mb temperatures fall at/below -28 C. This should occur to the west of an intense mid-level jet that will progress quickly across the Mid-Atlantic States and off the coast by evening. While the boundary layer will be drying, scant buoyancy may persist where mid-level lapse rates abruptly steepen. Much of the convection will probably remain as scattered showers, with thunderstorm coverage expected to be very isolated. Locally strong gusts could accompany this weak convection at peak heating across southern New England. ...Southwest... A low-amplitude shortwave impulse should dampen as it moves from the Lower CO Valley towards the southern Rockies. But adequate large-scale ascent coupled with scant buoyancy should yield isolated thunderstorms, mainly on Tuesday afternoon. Farther west, a separate shortwave trough will approach but remain offshore of the CA coast. Greater but still weak buoyancy from the Sierra NV Mountains across northern CA may support isolated afternoon thunderstorms. Weak deep-layer shear/ascent will minimize severe potential. ..Grams.. 04/14/2025
