It’s a very humid start to the day with cloud coverage, light rain and areas of patchy fog affecting south Mississippi. The low will begin to quickly pull away from the area later this afternoon, but an upper level disturbance will be moving through. This will result in continued cloud cover through much of the day.
Increasing subsidence throughout the atmosphere will result in a sunnier and warmer weekend. However, there will be the risk of some radiation fog forming tonight as the surface high builds in. Temperatures will rebound back to more normal levels over the weekend with highs in the upper 60s and lower 70s and lows in the upper 40s and lower 50s.
A cold front will sweep into the forecast area Monday night then push through the coastal waters and into the central Gulf of Mexico on Tuesday. At this time, instability looks sufficient to allow for thunderstorm development. However, the strongest dynamics will be displaced well north of the forecast area. At this time, the risk of severe thunderstorm development looks to be minimal at best. If any area saw severe thunderstorms form, it would be across portions of Southwest Mississippi. Temperatures will warm into the middle and upper 70s Monday afternoon in advance of the approaching front.
The risk of thunderstorms will diminish late Monday night as the front pushes well offshore. However, a general southwest flow pattern aloft will allow for post-frontal cloud cover and shower activity into Tuesday morning. A light freeze will be possible both Tuesday and Wednesday nights for most of the area. Only areas along the immediate coast are forecast to remain just above freezing in the middle to upper 30s.
