12/27 – Rob Knight’s “Final Week of 2021” Forecast
The first 24 hours or so of the forecast will be more of the same that we’ve seen over the weekend with partly to mostly cloudy skies and unseasonably warm temperatures. A weak impulse moving northward from the Caribbean around the west end of the ridge will move across the area tomorrow afternoon and evening. This will produce scattered to numerous rain showers, and can’t rule out a few rumbles of thunder.
Moisture doesn’t look like it’ll be particularly deep, but there’s enough instability and shear available where there’s at least some concern for strong to severe storms during Wednesday afternoon and evening. This would primarily be over southwest Mississippi, where the Storm Prediction Center continues to depict a Slight Risk during that time period.
For the first time in a while it looks like a true cold front could make it through the area only 2 days into the new year. However, confidence is low as there are question marks on how strong it could be this far south and when it actually makes it through. The other interesting factor is even if it makes it through and is still strong the cold air will only hang around for about 48 hrs. Your New Year’s Eve celebrations should have fairly limited impacts. We will be warm, likely rain free that night, and fog potential doesn’t appear to be as high and this should provide excellent conditions for your firework viewing pleasure.
