SPC 0730Z Day 3 Outlook Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0219 AM CDT Mon Nov 01 2021 Valid 031200Z - 041200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not currently forecast across the contiguous United States on Wednesday. ...Synopsis... A longwave mid-level trough will be over eastern North America while a ridge is located over the Interior West. A disturbance moving southeastward into the base of the larger-scale trough will aid in showers/thunderstorms developing across central into eastern TX and LA on Wednesday and Wednesday night. A frontal zone will push southward through north-central TX and into the Hill Country during the day. Weak buoyancy with parcels rooted near 700 mb will result in episodic clusters of showers/thunderstorms continuing from Tuesday night into Wednesday morning and persisting through the period as this activity moves southeast to the coast. Farther west, a vigorous mid-level trough over the eastern Pacific will approach northern CA/OR with isolated thunderstorms possible near the coastal range. ..Smith.. 11/01/2021 Read more LIVE:
