With a humid air flowing back into the area, light patchy fog has developed this morning in advance of an approaching cold front. Showers and thunderstorms will move in late this afternoon into tonight with windy conditions after the cold front passes. The cold front that will be moving through tonight bringing another cold air blast that will last through the weekend.
This front will not be anything like the next cold front. The next one will put the “cold” in cold front. A line of showers and thunderstorms should move through the area rapidly starting late Monday evening and should be clear of the area by mid Tuesday morning. There are some hints of a light wintry mix north of Hattiesburg just as the moisture is thinning out.
The dry air coming in does so in a very deep fashion which is normally capable of rapidly flushing deep moisture out. But there is always that chance of getting some mix just before it
moves out. If this does occur, it should remain confined to the northern half or less of the area.
Temps will fall rapidly as well back into the mid to upper 30s by daybreak Tuesday and may struggle to get into the mid or upper 40s over the northern counties for highs on Tuesday. We will likely be getting our first freeze of the season Tuesday night into Wednesday morning. The cool air looks to remain with us into next weekend.
