It’s a wild week for the weather. While snow will be an issue to the north later in the week, we will perhaps get to forecast some strong thunderstorms.
At 1207AM, CT, Hattiesburg was reporting a temperature of 60 degrees with mostly cloudy skies. There was light rain slicing through the middle of the state, and more substantial rain along the coast, but the Hattiesburg area finds itself in the middle of a dry donut hole. High pressure was developing over the Mid Mississippi Valley, and a return flow that had been tracing for an area of low pressure in the mid Atlantic will be cut off, with moisture lingering over the south through the day on Monday.
As this moisture lingers and surface high pressure descends southward, there will be a chance for scattered showers across southern Mississippi all day on Monday. High pressure will be ushered quickly eastward Monday night into Tuesday, which will open the Gulf back up. The pattern will become less stagnant over Mississippi, but no less rainy. Most significant shower and snow activity will be in the upper Midwest, which will lie in the exit region of a sharp western trough, but return flow once again will be through Mississippi, and scattered showers are fairly likely.

Not everyone sold on rain for Tuesday, I see. With an increasingly vigorous flow moving through a moist environment, I don’t see how they don’t get some showers. Here is the very shower filled radar for the region.
