AMZ400 Synopsis For Altamaha Sound Ga To Flagler Beach Fl Out To 60 Nm- 301 Pm Edt Thu May 9 2024
Synopsis..
a squall line of strong to severe Thunderstorms will traverse the georgia waters during the mid to late afternoon hours today, with this line reaching the northeast florida waters during the late afternoon and early evening hours. This squall line is expected to weaken after Sunset as it approaches the waters from st. Augustine southward. Strong to severe Thunderstorms will be capable of producing damaging wind gusts, hail, and frequent lightning strikes. Otherwise, a cold front will enter the southeastern states tonight and will progress southeastward across our local waters on Friday afternoon and evening. Additional rounds of strong to severe Thunderstorms will be possible after Sunrise and again during the afternoon hours ahead of this front. Winds will shift to northwesterly in the wake of the frontal passage on Friday night and Saturday morning, with weak high pressure the expected to build eastward from the ozarks on Saturday night, reaching the coastal carolina region by Monday afternoon. This weather pattern will result in onshore wind development on Sunday afternoon, with onshore winds then strengthening on Monday night ahead of an approaching warm front. Showers and Thunderstorms will overspread our local waters by late Monday night as this warm front lifts northeastward across our area.
