12/27 -Rob Knight’s “Muggy” Friday Morning Forecast

A steady plume of low and mid-level moisture has begun to move into the local areas from the Gulf of Mexico with light rain likely to persist across the area today. High temps will be several degrees above normal around 70 degrees.

An upper level low-pressure near California will move across the Desert Southwest today before tracking northeast over the Rockies Saturday as it will be absorbed by another system to its north. Models are indicating a very warm air mass in advance of the cold front…in the mid-70s for max temps which will approach records for this time of year…mainly in and around the Hattiesburg area.

The more impactful activity looks to come in on Sunday as a cold front will move east through the area. Models show weak mid-level instability which could lead to a few strong to marginally severe storms, mainly northwestern of the area in SW Mississippi. Damaging winds will be the main threat with weak tornado a very secondary threat. T-Storms will finally clear out Sunday evening/night.

At least a couple days of quiet weather is anticipated to start the week next week. A 20 degree drop in temps can be expected with highs Monday and Tuesday only in the mid to upper 50s. Lows that time frame should be upper 30s to mid-40s.
