Marine Weather and Tide Forecast for Killian, LA

LONG TERM
(Monday through Thursday)
Issued at 254 AM CST Fri Jan 24 2025

Shower activity will continue into the morning hours on Monday, but the best forcing will shift to the east of the area by the afternoon and increasing subsidence aloft will support a return to dry conditions in the afternoon hours. These dry conditions will persist into Monday night. The zonal flow regime aloft will allow temperatures to remain near average with highs in the low to mid 60s and lows in the upper 40s and lower 50s. Tuesday will remain largely dry as temperatures climb into the mid to upper 60s. At most some very light showers could develop with daytime heating and some weak lift aloft beneath a passing jet streak, but these will be very short- lived. Have included a 20 percent PoP to account for these light rain showers.

Conditions will turn more favorable for shower activity to return on Wednesday and Thursday. The region will find itself beneath the right entrance region of a jet streak in the upper levels on Wednesday, and this will support increased forcing aloft. This forcing will tap into the warm and moist airmass in the low to mid-levels to produce scattered shower activity throughout the day. Model soundings indicate there may be some limited instability, so have included a mention of isolated thunderstorm activity across southwest portions of the CWA Any thunderstorm activity will be low topped and short-lived given the limited overall instability in place. Otherwise, temperatures will rise into the upper 60s and lower 70s both Wednesday and Thursday afternoons and overnight lows will only cool into the 50s. There is a fair degree of model spread in the overall pattern from Thursday onward, and have opted to stick with the NBM solution for this time period.

AVIATION
(06Z TAFS)
Issued at 254 AM CST Fri Jan 24 2025

An area of mid level clouds is rapidly approaching from the western Gulf. This will bring about a 6 hour period of ceilings with cloud bases around FL100-120 at all terminals with the possible exception of KMCB. The upper trough approaching from the northwest should clear these clouds from all terminal areas with its passing around midday Friday.

Issued at 254 AM CST Fri Jan 24 2025

Through early next week, a surface high pressure system will move through the waters and then become centered just to the east of the waters. Winds will remain gusty offshore today with exercise caution headlines for the western waters, but winds will drop off quickly tonight and tomorrow as the surface high becomes centered directly over the area. These lighter winds of 10 knots or less will gradually shift to the south over the weekend and remain out of the south into early next week. Seas will also decrease from 2 to 4 feet today to 1 to 2 feet this weekend into early next week.
Overall, no significant weather impacts to maritime operations are anticipated through next Wednesday.
