SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1134 AM CDT Wed Oct 07 2020 Valid 081200Z - 091200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FOR SOUTHERN LOUISIANA... ...SUMMARY... A tornado is possible over southern Louisiana Thursday night. ...Central Gulf Coast... Hurricane Delta is forecast to move north over the west-central Gulf of Mexico on Thursday and Thursday night and approach the Louisiana coast according to the National Hurricane Center's latest forecast. A maritime tropical airmass will gradually infiltrate the coastal parishes of Louisiana during the day and the I-10 corridor during the evening and overnight. Within the outer northeastern envelope of Hurricane Delta, low-level flow is forecast to intensify across southern Louisiana with enlarged hodographs. As low-level moisture increases and surface dewpoints rise into the lower-mid 70s F, the development of 200-800 J/kg MLCAPE is possible across southern Louisiana. A few of the stronger updrafts located in the outer bands of Delta may yield intermittent storm-scale rotation and a possible tornado risk, mainly late Thursday night into early Friday morning. Elsewhere, generally tranquil conditions will occur across much of the contiguous United States. ..Smith.. 10/07/2020
