SEVERE THREAT TUESDAY/TUESDAY NIGHT: The next storm system will push a cold front into northern Louisiana early Tuesday morning and towards SE Louisiana and coastal Mississippi Tuesday afternoon. The Storm Prediction Center has made some adjustments to the outlook for Tuesday’s storm potential. Metro New Orleans to I-12 is now under a slight risk (level 2 of 5) for severe storms, areas along I-12 and north are under an enhanced risk (level 3 of 5). Areas south of Metro New Orleans to the coast are under a marginal risk (level 1 of 5). Damaging winds will be the primary concern, followed by a risk for hail and isolated tornadoes. Showers and storms will continue through Tuesday night.
HEAVY RAIN THREAT: Locally heavy rain will be possible with Tuesday’s storms. There is a level 2 of 4 risk for street flooding. A Flash Flood Watch has been issued for the Northshore and coastal Mississippi through 1am Wednesday. Rain totals of 1-3” will be possible for most, while some locations may pick up higher totals.
WEDNESDAY & THURSDAY: The front won’t move offshore until Wednesday morning, and will become stationary. So scattered showers and storms will continue through Wednesday morning, with trailing showers and storms through afternoon. Outside of a few coastal showers early Thursday, the area will be on to drier conditions. Morning temps will be in the 60s, with afternoon highs in the upper 70s and low 80s. Humidity will be lower Thursday behind the front.
FRIDAY & THE WEEKEND: High pressure will build over the region behind the departed cold front. Enjoy the lower humidity. Temps will be closer to average Friday and into the weekend. Morning lows will be in the 60s. Afternoon highs in the low 80s under sunny skies. Humidity will start to increase into the weekend as high pressure slides east of the region. The next front may bring a few showers late Sunday and into early next week.
