12/16 – Brantly’s “Rain Moves Out, Cold Air Moves In” Wednesday Forecast

The low pressure will then move east of the local area by this afternoon, with a well-established northwest flow in its wake as high pressure takes hold through Thursday. Winds could be gusty at times today, particularly near the coast. Dry conditions are then expected to round out the near term period. Highs today will struggle to get out of the 50s. Strong cold air advection will then cause lows tonight to sink into the upper 20s over far inland portions of southeast Mississippi and southwest Alabama. Lower to upper 30s are then expected for the rest of the local area tonight. Highs will be chilly again Thursday afternoon, with high temperatures only reaching the lower to mid 50s.

At the surface, high pressure will dominate the forecast for the next few days allowing for cool and dry conditions to prevail. This high pressure system gradually moves off to the east and northeast, eventually moving into the Mid-Atlantic region by Friday night and stretching southwestward to the northern Gulf of Mexico. Forecast highs begin a gradual rebound Thursday and Friday, featuring upper 40s to lower 50s Thursday and middle to upper 50s Friday.

Another cold front is expected to cross the area this weekend, but weather models are still split on how strong it will be and how much rain will be associated with it. There is a modest increase of moisture right ahead of the front, so expect some showers through most of the weekend. Most models have this next front pushing offshore by Sunday so that should limit any heavy rain potential. Moving into early next week, weak high pressure builds into the north gulf coast region and dry and seasonable temperatures should return for a couple days.
