Synopsis...
Surface High Pressure Continues To Move Off To The East Through The Day While A Surface Low Begins To Develop In The Texas Panhandle. The Result Is Winds Turning Out Of The East-Southeast, And With A Tighter Pressure Gradient, An Increase In Wind Speed. The Combination Of An Upper Level Disturbance And The Aforementioned Surface Low Moving Through The Region Will Lead To Increased Shower And Thundershower Chances Through Late Thursday. Precipitation Will Taper Off After A Cold Front Moves Through Late Thursday, With A Moderate Offshore Flow Developing. Lighter And More Variable Winds Are Expected By Late Friday And Into Saturday As High Pressure Builds In. Another Upper Level System Moves Through On Sunday, Bringing Increased Winds And Rain Chances Yet Again.
