Good Sunday afternoon, we are just eight days away from Christmas and a lot of people will be out and about shopping or enjoying pre-holiday parties with friends, family or co-workers…
The weather pattern here in the Southeast looks to be unsettled going into this upcoming week. Ridging that dominated the west coast over the past couple weeks has broken down and has been replaced by a trough and upper level low centered over Arizona. Meanwhile in the Southeast we are being more influenced by broad ridging that stretches from the Southwest Atlantic into the NW Caribbean.
Those two features help yield a strong southwest flow at the jet stream level across the Southeast US pumping in moisture from the Gulf and even a bit of Pacific moisture at the mid and high levels as you can see on the water vapor.
This will all lead to an unsettled week with plenty of clouds and at time precipitation. With the mild southwest winds, all precip will be liquid in nature.
As you can see on the model loop, showers will generally dissipate later today and tonight, however parts of the coverage area will see a brief shower at any point over the next 12-24 hours.
Monday and Tuesday looks to be fairly dry as moisture remains south…it will be on Wednesday that our next southern stream energy will move in. Global model guidance is converging toward a healthy system for Wednesday, so if there is a timeframe that we are most wet, it will be the mid-week timeframe.
Temperatures during this timeframe will remain mild due to increased moisture. 60’s are forecast for Monday due to possibly seeing the most sunshine. Then 50’s should be common through the mid week. Night time temperatures will also warm up considerably with numbers stay at or above the freezing mark after Monday.
All indications are that unsettled weather may hang around even past the mid-week timeframe and could have impact on the holiday travel next weekend. Here's a look at WPC projected rainfall amounts through Thursday.
