10:30PM Saturday: Active forecast for Sunday, Flash Flood Watch in effect at 1AM!


Once again, this was a nice, quiet forecast for your Saturday across southeast Louisiana and New Orleans, itself, on Derby Day!

Yesterday, we were dealing with slightly warmer outlooks, especially in comparison on last week. Tough to stay inside in dry conditions with sunshine plus clouds, considering upcoming changes on the way tomorrow.

Anticipate an overall pleasant night tonight, as well with 60s north of Lake Pontchartrain and low 70s south!

Sunday morning into afternoon, storms return and there’s the growing possibility of severe weather. A Flash Flood Watch is issued from 1AM Sunday to 1AM Monday for much of the Northshore and western Louisiana as 1-3 inches in rainfall will likely accompany thunderstorms.

Anticipate an increase in rain chances by late morning, especially north. These stick around through late evening with improvements by Sunday night! Right now, the Storm Prediction Center is issuing a Slight Risk (Level 2 out of 5) nearly state-wide, then expanding it east.

Aside from flash flooding, gusty winds and hail potential are the primary concerns with an isolated tornado risk being tough to rule out entirely.

Have ways to receive warning information in case a severe thunderstorm or tornado organizes. Keep up, updates remain avaialable online on WGNO.com and tomorrow during WGNO News at 5PM and 10PM!
