AMZ400 Synopsis For Altamaha Sound Ga To Flagler Beach Fl Out To 60 Nm- 912 Pm Edt Sat May 18 2024
Synopsis..
a frontal boundary will remain stalled over our local waters through Sunday night. The next wave of showers and possibly a few embedded Thunderstorms will occur after midnight through the predawn hours on Sunday. A break in activity is expected on Sunday morning, followed by the next round of showers and Thunderstorms during the afternoon and evening hours on Sunday. Strong to isolated severe Thunderstorms will be possible with this activity, with stronger storms being capable of producing damaging wind gusts, frequent lightning strikes, and heavy downpours. High pressure building over new england on Sunday will then Wedge down the southeastern seaboard during the predawn and early morning hours on Monday, pushing the frontal boundary south of our local waters. North-northeasterly winds will surge to caution levels on Monday, with speeds gradually decreasing on Tuesday and Tuesday evening as high pressure begins to settle directly over our waters. Chances for showers and a few embedded Thunderstorms will persist on Monday and Monday night. High pressure will then shift offshore towards midweek, resulting in prevailing southerly winds across our local waters.
