Excessive Rainfall Threat Added to Louisiana’s Severe Threat
Tuesday will likely be a stormy day across most of Louisiana as forecasters with the National Weather Service say residents of the state should be on standby for not only severe storms but there is also the potential for excessive rainfall associated with these storms.
A cold front and an area of low pressure in the upper atmosphere will track across the state beginning late tonight and throughout the day on Tuesday. For much of South Louisiana, the rain and storm threat will begin from the west about sunrise on Tuesday. Although the timing of the inclement weather's arrival is not written in stone it's a pretty safe bet that much of southwestern Louisiana will be dodging raindrops by 9 am Tuesday or sooner.
You can see the outline of where the Storm Prediction Center believes the strong storms will occur. As you can see, a portion of the state is in the enhanced risk category. While the extreme northeast corner of Louisiana is in a very dangerous moderate risk of severe storms.
While the part of the state which includes Baton Rouge, Lafayette, and Lake Charles is only at a slight risk for severe storms. The rest of the state should be considered to be at a marginal risk of severe weather.
Remember these outlines are like forecast models, they are only a guideline and should not be taken as an official forecast. So, basically, if you're in Louisiana you're going to see storms on Tuesday, but what about the excessive rainfall?
Excessive Rainfall is a term that is used a lot by forecasters but is widely misunderstood. Basically, excessive rainfall is based on the relationship of how much rain will fall over a given period of time versus how long the area rained on needs to sufficiently drain that water away. So, this is less about total rainfall and more about rainfall rates over a specific time period.
Only the extreme eastern and northeastern portions of the state are included in the slight risk of excessive rain while the rest of us are dealing with a marginal risk of excessive rain.
The good news is the inclement weather should pass through the area during the day on Tuesday and by Wednesday conditions across the region will improve a lot. The forecast for the remainder of the workweek calls for sunny skies and seasonable temperatures all the way through the weekend when South Louisiana will once again see a chance of showers.
