The Flash FLood Watch has been cancelled for all of the Louisiana zones as the last of any heavier rain showers has moved into MS. A few more isolated rain showers will remain possible this afternoon, but are expected to be light in nature. The heavier showers should clear the MS coast within the next 1-2 hours. HRL
.SHORT TERM... (Today through Sunday) Issued at 420am CST Sat Dec 2 2023
Main issue across the area this morning continues to be the severe weather and heavy rainfall threat. Overnight, several areas received in excess of two inches of rain and a few cells became severe. Currently, the severe threat is beginning to diminish and the tornado watch has been allowed to expire at 4AM. There is certainly a continued possibility of an isolated severe storm but overall the threat does not warrant an extension of the watch. The flash flood watch will continue until 6AM this morning and at this time the plan is to let it expire as well.
The cold front is still off to the west and is slowly making progress towards the area. Southwest flow will continue until the front makes it through the area, allowing for rain chances to remain elevated throughout most of the day. After the front pushes through tomorrow, drier conditions will spread into the area for Sunday with temperatures remaining near 70 across most of the area before a cooler night Sunday night.
(Sunday night through Friday) Issued at 420am CST Sat Dec 2 2023
After the frontal passage, the area will settle into a drier pattern with temperatures returning closer to normal for the beginning of the work week and persisting into the middle of the week. By late in the week, temperatures will begin to moderate as onshore flow returns.
Issued at 420am CST Sat Dec 2 2023
A cold front continues to very slowly drift towards the area with onshore flow remaining in place in advance of the front. A series of low pressure systems will pass north of the coastal waters. There is the potential for patchy fog nearshore early this morning, especially in areas where the rain has tapered off. A cold front will move through late Sunday allowing high pressure to finally build over the northern Gulf for the start of the new week diminishing winds and seas over the coastal waters.
