MERIDIAN, Miss. (WTOK) - It was a cloudy, even somewhat foggy start to this Sunday early in the morning, but that didn't prevent highs from climbing into the upper 70's and lower 80's this afternoon. Warm, humid air that settled in last night aided in those clouds and fog to form into the early morning hours. All of that quickly dissipated by the afternoon, making way for more partly cloudy skies. Tonight we'll rinse and repeat the same cycle. Temperatures will gradually drop down early with skies becoming more cloudy later on with lows in the middle 60's. Winds will die down as well allowing for patchy dense fog to form up in some locations.
Ridging will continue to prevail across the Twin States, with moisture being brought in from the Gulf through Tuesday. A frontal boundary will situate just off to the north near Memphis, but this boundary won't affect us other than for a few more clouds than previously expected. We'll continue to be warm and humid with highs in the lower 80's and lows in the 60's through Tuesday under this air mass. Skies will go from partly to more mostly cloudy by Tuesday.
Tuesday night into Wednesday the frontal boundary will finally get moving and swing through as a cold front. Most of the rainfall with this front will be behind the front, so scattered showers will enter in Wednesday. Highs will drop back into the middle to upper 60's. Models are still being split on their decision with timing for the exit of the shortwave causing the rainfall and front. Based on what I'm seeing, I'm expecting showers to continue through Wednesday night, with a leftover shower possible early Thursday but otherwise it should be a dry day.
The rest of the week into the weekend will be sunny and seasonable with highs in the upper 60's/lower 70's and lows in the upper 40's/lower 50's behind the front. The rest shot at another cool down and rain comes with the next front Saturday night into Sunday. This is something to watch, since it's so far out and exact timing is still up in the air.
