12/9- Rob’s “Warmer Temperatures Ahead” Afternoon Forecast
As the upper-patterns through the CONUS starts to slide east, high-pressure to our west moving towards the Lower MS Valley will weaken. The next weather maker will sits west, not affecting the area until this weekend. The biggest change could be morning lows Friday morning which may be about 7-10 degrees warmer than tomorrow morning. As for weather, we will be dry with little in the way of clouds if any through Friday afternoon.
The upper-level disturbance will affect the region heading into the weekend with mainly showers, but a few embedded t-storms could affect the area Saturday/night. The surface front should push through the region on Sunday with winds becoming northwesterly, winds aloft remain southwesterly.
The upper trough should finally swing through Sunday night. As it does so, there is potential a low could even close off over the Lower Mississippi Valley. If this happens, the forecast gets a little tricky with the end time of the precip and the arrival of colder air. Right now it looks like precip moves out before any flakes mix in, but IF precip lingers a little longer, a few flakes could still mix in north of Hattiesburg Sunday night/early Monday morning.
