AMZ400 Synopsis Issued: 915 AM EST Wed Jan 22 2020

Synopsis...
Low Pressure Strengthening Just Northeast Of The Bahamas Will Pivot Eastward This Afternoon As Arctic High Pressure Moves Eastward And Reaches The Mid-Atlantic Coast By Thursday Morning. Strong Northerly Winds With Frequent Gale Force Gusts Today Will Gradually Weaken Overnight As A Coastal Trough Develops Over The Near Shore Waters, Which Will Generate Scattered Showers Through Thursday. Winds Will Shift To Northeasterly On Thursday As The Coastal Trough Moves Onshore And High Pressure Gradually Weakens Over Coastal New England. Meanwhile, Weak Low Pressure Developing Over The Lower Mississippi Valley On Thursday Will Shift North- Northeastward Through The Tennessee And Ohio Valleys On Friday, Dragging A Cold Front Across Our Waters On Friday Afternoon And Evening. High Pressure Will Then Build Into Our Region From The West This Weekend, With Offshore Winds Expected In The Wake Of The Frontal Passage. Seas Will Remain Elevated Over The Offshore Waters Through Saturday Before Gradually Subsiding Late In The Weekend.
