Area Forecast Discussion National Weather Service Lake Charles LA 611 AM CDT Tue May 11 2021

AVIATION. Numerous storms will occur during the period as a front remains stalled today then shifts south tonight. This will produce lower vis and ceilings. SE winds will occur along the coast with northeast winds north of I-10. NE winds are expected at all terminals this evening.

PREV DISCUSSION. /issued 444 AM CDT Tue May 11 2021/

DISCUSSION . The POE and LCH radars were beginning to light up this morning in response to the stationary front across the I-10 corridor. Showers were developing along and north of the front. Temperatures north of the front were in the mid 60s to near 70 . while south of the front temperatures were in the mid to upper 70s.

The stationary front is expected to lift northward to interior southeast Texas and central Louisiana this afternoon. Daytime heating . pooled moisture . and the front will act in tandem to trigger showers and thunderstorms. Heavy rainfall is possible near the front as precipitable Water in the atmospheric column is expected to increase to 1.75-2 inches which is right around the daily maximum for May. A Flash Flood Watch (FFA) has been issued for this afternoon through the rest of Wednesday morning for the northern areas of interior southeast Texas and the parishes north of the I-10 corridor. I also added parts of south central Louisiana where there could be backbuilding overnight into Wednesday morning The good news. is that recent rains were less across lower southeast Texas and southwest Louisiana . so do not believe the FFA will be needed with this event. Cross fingers.

The front will get moving tonight and finally reach the coastal waters Wednesday morning. Northerly flow behind the front will increase and should sweep the remaining rains into the gulf by Wednesday afternoon. High pressure will build in with cooler weather Wednesday through early Friday. Southerly flow will return on Friday allowing for a gradual warmup into the weekend as pressures fall across the plains ahead of the next trough over the western United States. Rain chances return Sunday into Monday as the system approaches the region.

MARINE . Light to modest onshore flow will continue today. Showers and thunderstorms will become more widespread Tuesday night into Wednesday as a weak surface front moves through the coastal waters. Offshore flow develops by Wednesday morning behind the front with onshore flow returning once again by Friday evening.
