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.
