UPDATE
Issued at 1136 PM CDT Thu May 16 2024
The remainder of the Tornado Watch will be allowed to expire at midnight. There still maybe a localized severe threat that can be handled with a warning for the St. Mary Parish area. Also, concerned with thunderstorm development near the lower Acadiana coast that will come onshore and bring a flood risk for at least St. Mary Parish where a flash flood warning is in effect through 2 am.
Still some uncertainty how things will play out tomorrow as to where the potential mcs will form tomorrow afternoon into Friday evening. Thus have left the flash flood watch the way it is.

SHORT TERM
(Tonight through Saturday night)
Issued at 205 PM CDT Thu May 16 2024
The warm front is currently lifting across the region with a rapid destabilization of the atmosphere underway. CAMs show a robust and rapid development of showers and storms with multiple focus areas. The first area will be an east/west oriented MCS walking south that will move into central LA and inland SETX this evening.
The second focus will be in the broader warm sector south of the lifting warm front.
Numerous showers and storms will rapidly intensify and drift/merge into the MCS walking south. This will enhance the overall flash flood threat as training convection could lead to impressive 1hr/3hr totals, especially where cell mergers are able to push instantaneous rainfall rates in the 5-7" range. With already saturated grounds and elevated/flooded waterways, it will not take much for significant flash flooding. In fact, we have much of the area in a moderate and high risk for this very threat. These High Risk days are exceedingly rare and account for the majority of flood fatalities. We can not emphasize enough how quickly things could go south as the evening wears on. Flash flooding is even more dangerous at night.
For the severe threat, there is a Tornado Watch until 11pm for the entire area. Tornadoes will be possible with any QLCS circulation and/or supercell along/just south of the lifting warm front.
Damaging winds and large hail will also pose a threat this evening withe modest HRRR probabilities showing wind gusts in excess of 50kts and localized areas upwards of 60kts possible. The focus area seems to be along the I-10 corridor.
With regards to rainfall amounts, widespread 2-6 inches are likely, which is supported by all guidance with HRRR LPMM/HRRR/Other high res CAMs showing a reasonable worst case (90% exceedance) scenarios of approaching 12" of rain. Highest probabilities for these totals exists across inland SETX and into central LA.
Now for the second round from Friday afternoon into Friday evening and early Saturday morning. This situation will be different as SW flow increase across the area with robust upper level diffluent flow. This overall synoptic pattern remains stationary for some time, which will allow significant and sustained moisture advection streaming across the region. While severe weather is possible, flash flooding remains the biggest threat. PWAT values could reach into the 2.0 to 2.25"+ range with favorable and efficient ingredients for intense rainfall rates and training.
ECMWF EFFI values point to significant rainfall totals, which further adds to the building confidence in the second round. As always, there remains some uncertainty as to where the axis of heaviest rainfall sets up. Currently guidance suggest this will fall primarily over Acadiana and generally east of a line from Lake Charles to Opelousas. Several more inches of rain will be possible in these areas with new/renewed/worsening flash flooding impacts. It is likely some areas will overlap seeing significant rainfall from round 1 and 2, thus increasing their flood risk.
Finally by early Saturday morning, much of the activity should be exiting the region. Lingering showers/storms will be possible over Acadiana, but much of the area dry.
LONG TERM
(Sunday through next Wednesday)
Issued at 205 PM CDT Thu May 16 2024
The start of next week will be dominated by high pressure that will settle overhead. The high pressure will remain our main weather feature through Wednesday. Clear skies and south winds will lead to widespread low 90-degree highs across the region, with dew points in the mid-70s. This will lead to heat index values in the upper 90s and even a few inland areas feeling like the triple digits.
Long-range models are starting to hint at another round of rain on Thursday as a disturbance moves across the region. It is still way too far out to give any specifics, but we could see our temperatures dip down back into the upper 80s.

Issued at 1136 PM CDT Thu May 16 2024
Some lingering shower activity will be possible near the KARA terminal through about 17/09z. Otherwise, MVFR to IFR conditions from low clouds and possible patchy fog will be the main story during the night into early Friday morning.
Still some uncertainty to where the potential thunderstorm complex will develop on Friday afternoon. Therefore, just broad brushed each terminal with a PROB30 group between 1718z/1724z.
