Marine Weather and Tide Forecast for Vidalia, LA

DISCUSSION
Issued at 359 AM CDT Mon May 12 2025

Today and Tonight: Early morning satellite imagery/RAP analysis showed the circulation around a closed low centered over our southwest Mississippi zones. Early morning surface analysis had an 1011mb low centered over our north central Mississippi zones. These two features will lift slowly to the northeast through tonight becoming centered over the Tennessee valley by Tuesday morning.
Drier air wrapping around and into the low pressure system has led to much less precipitation over our CWA early this morning as compared to last night. Satellite imagery shows significant breaks in the overcast as well. The low pressure system will continue to help develop light rain and light drizzle at times this morning.
Daytime heating will lead to greater development including scattered to numerous coverage by mid afternoon. Similar to yesterday, the greatest coverage will be over the northeast half of our CWA where thunderstorms can also be expected mid afternoon into early evening.
The convection will show a diurnal trend this evening but the surface low and closed low will be to our north resulting in decreasing rain chances from the southwest as well. Temperatures will be cooler than normal again today and tonight. /22/

Tuesday through Sunday...The mid/upper level low pressure system responsible for the rain and storms across the forecast area the past few days, will lift northeast of the region Tuesday into Wednesday. Before it exits, this weakness will again result in scattered to numerous showers, along with a few thunderstorms, across mainly the Golden Triangle area Tuesday afternoon. This activity will dissipate in the late afternoon, as heating wanes and the low lifts further northeast and out of the region. Otherwise, look for highs Tuesday afternoon from the mid 70s to mid 80s, with lows Tuesday night from the middle 60s to around 70.

Ridging aloft and high pressure at the surface will setup across the region Wednesday into Thursday. This will result in a return to quieter conditions, but with increasing temperatures. On Friday, the ridge will begin flattening, with quasi-zonal flow prevailing across the CWA through the weekend. It'll be during this Friday through Sunday timeframe, that a couple of disturbances aloft are advertised to affect the region. These disturbances, combined with the expected unstable airmass that'll be present across the region, in addition to some flow, could yield some potential for a complex of storms or two, possibly affecting portions of the CWA Again, this will be in the Friday through Sunday timeframe. This is still several days out. Please continue to monitor the latest forecast for the most up-to-date information.

As eluded to above, temperatures will be on the rise areawide under the influence of the aforementioned ridge and high pressure. Highs will steadily warm through mid-week, with low to mid 90s expected nearly areawide come Thursday, with lows struggling to fall out of the 70s. The upper 80s to lower 90s will continue each afternoon heading into the weekend. However with the increased rain chances around each afternoon, convection, and outflow and clouds associated with it, will likely keep highs slightly less than what they could potentially reach. /19/
