After a few days of intermittent rainfall and sticky conditions, we’re going back to the cool and dry that we all know December for. Temperatures will dip back down to the 50s and 60s for the better part of the week and we’ll see a couple of frosty mornings ahead of us too.
On the synoptic scale, a myriad of shortwave troughs from the upper levels will move through the eastern US. For the deep south in particular, the troughs are dry and will pull in more Arctic air from the north and keep temperatures down and the skies fairly clear. Temperatures will likely reach the freezing point on Tuesday and Wednesday. By Thursday, the strong height anomaly you see above (in red) will allow the heights to rise and with that, temperatures will also be on the rise. Couple that with winds from the south in the Gulf, we’ll see more of the build-up of warmer, more humid conditions by Thursday and Friday.
As shown above, another significant trough will develop around Saturday into Sunday, and with it, another chance for storms. This is still pretty far out, but both the GFS and Euro models agree that this will be a fairly organized line of storms. Judging by the orientation of the trough, it reaches down far enough to raise an eyebrow as to what may happen next weekend. For now, we’ll have to wait until we get a bit closer to the weekend to see what possible parameters and significant threats may come with this system.
