Marine Weather and Tide Forecast for Richton, MS

DISCUSSION
Issued at 303 PM CDT Tue Oct 15 2024

Tonight through Wednesday: Dry cold air advection will be the dominant weather influence through the near term. With increasing post-frontal subsidence, surface wind will be on the increase, especially in the ArkLaMiss Delta region where forecast wind gusts up to around 35 mph have prompted the issuance of a limited threat in our HWO graphics for this evening. Another potential impact associated with wind and drier air will be wildfires, and we have upped the threat to elevated for the entire area as we go into Wednesday. Otherwise, the cooler air will be a significant story in itself, and some locations along the Highway 82 corridor could dip below 40 for the first time since early last spring.

Wednesday Night through next Tuesday: Early afternoon global guidance highlight a strong surface high settling over the Mid Tennessee Valley. This will help keep sky conditions generally clear across our forecast area heading into the late evening hours on Wednesday allowing for the radiational cooling to occur.
Because of this, Wednesday night/early Thursday morning appears to be the coldest period with nighttime temperatures dropping into the upper to perhaps even mid 30s in the Golden Triangle region some light patchy frost will be possible. Temperature forecast for this time frame was adjusted by using some slightly cooler model guidance in order to account for this. Ridging aloft will begin to build into the southeast region heading into Thursday.
This combined with the aforementioned sfc high with help keep weather conditions generally quiet through the entire extended forecast period.

Temperatures will start to rebound quickly as we head into the weekend. Heading into the new work week, the sfc high will begin to shift east. This will allow for south/southwesterly winds to return to the area along with a few clouds. Future guidance does show a frontal boundary in the Central Plains moving east towards east CONUS by early next week which could help introduce some low rain chances across parts of the Delta region by then. /CR/
