12/23 – Rob’s “Severe Threat (Tonight)” Wednesday Morning Forecast
High pressure will continue to slide to the east with a southerly flow becoming established across the area. A cold front will approach from the west setting up winds from the SW increasing the moisture flow. This will aide in instability with a few showers or isolated thunderstorms developing out ahead of the main punch which is expected tonight as the cold front approaches and then sweeps through the region around the early morning overnight hours.
There is a MARGINAL/SLIGHT risk for severe thunderstorms this evening for south Mississippi.
The Storm Prediction Center (SPC) indicates that instability does not favor widespread convection. However…along the frontal boundary…a few cells may develop some rotation and therefore pose a risk for damaging winds and possible isolated tornados.
The threat of severe weather will end Thursday with rain lingering early morning, ending from west to east. Strong winds will move in behind the front with gust through the day Thursday in the 20/30 mph range. A GALE WARNING is in effect tonight through Thursday evening. High pressure will build back in with dry northerly winds. Much colder air will settle in Christmas Eve night. On Christmas Day…colder air will settle into the area and remain entrenched through much of Saturday before the warm-up.
