Saturday, December 2 Forecast Discussion

By  | 

MERIDIAN, Miss. (WTOK) - Dense Fog Advisory is in effect for Pickens, Greene, Hale, Sumter, and Marengo counties in AL from 9 PM tonight until 9 AM Sunday.
Dense Fog Advisory is in effect tonight for all other viewing area counties from 12 AM until 9 AM Sunday morning.

Get ready for one heck of a roller coaster ride, as we'll get to experience three different types of weather this coming week. The first is fog, much like we had all day yesterday. This afternoon, the fog and low clouds were able to break up enough for some sunshine and temperatures climbing into the upper 60's. Fog will once again return tonight with calm winds and ample surface moisture. Visibility will be reduced to almost zero in many locations, especially our eastern counties. Be sure to drive safe if you are out and about tonight. Lows will stay warm, in the lower 50's, with all the dense fog.

Much like Brian emphasized in his forecast discussion yesterday, the forecast is difficult in the short term due to this fog. We've seen that when it doesn't burn off, we stay much cooler through the day and when it does, like it did today, we jump to near 70 degrees. There is still a lot of uncertainty in my forecast on this, but based upon recent trends and what the models are displaying, we're looking at much the same as we saw today for Sunday. Dense fog should hang around into the mid-morning along with low clouds before gradually breaking up into the afternoon. From there, partly cloudy skies will prevail and we'll warm up into the upper 60's again.

Ahead of the next front, winds pick up a bit Monday, ridding us of fog but increasing temperatures a bit more. We'll be into the middle 70's and feeling pretty humid for this time of year. Clouds start to stream in Tuesday with the front arriving in during the day, bringing the second phase of weather, rain. The parameters don't show any potential for severe weather, but heavy rain is very likely with all the available moisture. One to two inches of rain is likely, which is much needed with the drought conditions in place.

Behind the front, we get the third weather feature with lots of cold air. Plenty of cold, arctic-like air will funnel in starting Wednesday, which means outside of a leftover shower in the morning, we're looking at sunny skies straight into the weekend. Highs will struggle to top the 50 degree mark for much of this stretch, with lows plummeting into the upper 20's. If skies remain clear and winds die down enough, these lows could be even colder into the lower 20's. Many locations will get the first real hard freeze of the year with this cold shot.
