A Flash Flood Watch is in effect for portions of Southeast Louisiana and Southwest Mississippi through 1 AM Wednesday. Rain totals of 1-3″ with locally higher amounts are possible through tonight.
Today & Tonight: A dynamic system will begin to move into the region. Heavy rain and severe weather will be possible – mainly during the afternoon and evening hours in the form of a squall line. Storms may be possible ahead of the line and even behind the line. There is an Enhanced (threat level 3 of 5) for most of the BRProud area. Moderate Risk has been issued for Southwest Mississippi. The most intense activity will stay along and north of I-10/I-12. Damaging wind and heavy rain will be the main concern, but large hail and tornadoes will also be possible. Heavy rain may lead to some localized flooding issues. Rain totals look to be 1-2″ on average, but some may see double or triple those amounts, especially to the northeast of Baton Rouge. The main window of opportunity for severe weather will be between 2 PM and 10 PM, but severe storms can develop earlier or later than that timeframe.
We will be mostly dry and breezy during the morning hours. Best chance for storm activity will be during the afternoon and evening, but the cold front will likely trigger some additional storms overnight and early Wednesday. Highs near 87, but it will feel like the mid 90s. Overnight temperature near 64.
Wednesday: Early storms before the cold front finally pushes offshore. Gradual clearing with highs in the upper 70s to lower 80s. Overnight temperature near 59.
Thursday: We finally start to clear out and dry out. High will be near 82, but it will be more comfortable thanks to drier air in place. Overnight temperature near 57.
Friday & Weekend: Nice and comfy on Friday and Saturday before it gradually gets warmer and more humid. Highs in the low and mid 80s. Overnight temperatures in the 50s and 60s. Only a slight chance for rain on Mother’s Day with a high near 87.
