A Flash Flood Watch continues through noon for the Baton Rouge metro. The Flash Flood Watch has been extended for Assumption, St. James, St. John the Baptist, and the New Orleans metro through 4 PM.
Monday: An incoming cold front will eventually stall out and lead to rounds of rain through Wednesday. Flash flooding will be our main concern with storms today. There is a Marginal Risk for severe weather, as well. Main concern will be damaging wind and hail, but a tornado cannot be ruled out. For now, we are forecasting a 70-80% chance for rain. Most of the rain will fall in the morning and early afternoon before tapering late in the day. There will still be a few showers around during the evening.
Tonight: Scattered rain overnight and into early Tuesday. Rain chance is around 30-40%. Lows near 70°F.
Tuesday: Rain coverage is expected to increase by midday thanks to the stalled boundary and an upper-level disturbance. Heavy rain/flash flooding will be our main concern, but there may be a few strong to severe storms. There is currently a Marginal Risk for severe weather on Tuesday. Damaging wind and hail will be the main threats, but a tornado cannot be ruled out. Rain totals may be 3-5″ with locally higher amounts through Tuesday. If your area gets caught under a slow moving storm, you could easily double or triple those amounts. Rain chance is around 70% for the day. High near 84°F. Overnight temperature near 66°F.
Wednesday: More rain is expected. Organized severe weather threat is low, but not zero. Heavy rain continues to the be the main concern. Rain chance is around 70-80%. High near 75°F. Overnight temperature near 61°F.
Thursday: We will begin to dry out as drier air moves in. High near 77°F. Overnight temperature is 58°F.
Friday & Weekend: We look mostly dry and warm with highs in the low and mid 80s. A slight chance for a shower Sunday, but overall, the weekend looks quite nice.
