MARGINAL to ENHANCED RISK of Severe Thunderstorms WHEN:

• The heavy rain threat will be highest from this evening through Wednesday afternoon with rain continuing through Thursday.
• Isolated severe thunderstorms are possible on Wednesday but a higher threat of severe weather is possible on Thursday.

WHERE: The risk of heavy rainfall that could produce flooding issues and severe thunderstorms will exist across all of southern MS and southeast LA. CONFIDENCE: We are confident that there will be thunderstorms across the area and that a few will produce heavy rainfall and severe weather impacts.

• Additional rainfall of 3 to 6 inches is currently forecast. Locally higher amounts will be possible.
• Expect ponding of water in low lying areas and some potential for localized flash flooding.
• As water drains into area rivers, minor to moderate flooding could develop.
• Damaging winds in excess of 60 mph, hail, and a few tornadoes will be possible with any severe storms.

The attached briefing highlights the threats associated with this system.
