Synopsis: High pressure centered over our region this evening will move northeastward overnight and will become absorbed by a stronger high pressure center that will be moving off the New England coast by late Thursday. Meanwhile, low pressure will organize along the Red River Valley of northern Texas on Thursday night, lifting a warm front northward into the northeast Florida waters, resulting in strengthening southeasterly winds. This warm front will lift north of the Georgia waters early on Friday morning as low pressure pivots northeastward from the lower Mississippi Valley into the Tennessee Valley. A strong cold front will cross our local waters by early Saturday morning, with low pressure moving off the Carolina coast by Sunday afternoon.
