Heads up! Saturday is another WDSU First Warning Weather Alert Day for the potential of heavy rain, flash flooding & isolated severe storms.
A Special Marine Warning is in effect for Lake Pontchartrain until 8:45. A line of thunderstorms moving SE at 50 mph may produce a waterspout.
It will be another very wet day with numerous showers and thunderstorms moving in in the morning and afternoon. There is a marginal risk for severe weather throughout the day according to the Storm Prediction Center, as one of the storms could contain some hail or wind gusts close to 60 mph. An isolated tornado as possible, but not likely at all.
Rainfall out from one to 2 inches are very possible today, as the thunderstorms will develop on the North Shore in the morning and then move further south by the mid to late morning. It will still be a wet afternoon with the showers decreasing by 8 PM, and it should be mainly dry during the overnight hours.
High-resolution model guidance is once again coming in HOT with tomorrow’s round of storms by mid morning. Localized flash flooding and isolated severe weather possible. Main concern of heavy rain, gusty winds, small hail, lightning.
The Weather Prediction Center has upgraded the flash flood threat to Slight(Level 2 out of 4.) Widespread 1-3″ of rain likely. Hot spots of 4+ inches possible.
With soils being a bit more soggy from today’s heavy rain in spots, the flood risk could quickly elevate with any training of storms. Stay alert.
Timing has trended earlier with storms developing by 6AM-10AM across the Northshore and continuing into the early afternoon across the South Shore.
We may see a nice break by the afternoon?! Additional scattered storms possible into the late afternoon/evening, but that part of the forecast is a bit more uncertain.
By Sunday, the first half of the day looks more tranquil before additional storms possible Sunday afternoon into Sunday night.
Finally, by Monday, this stubborn weather pattern looks to exit with much nicer weather early next week.
