Marine Weather and Tide Forecast for Flowery Branch, GA

SHORT TERM
(Today through Saturday)
Issued at 150 AM EDT Fri Apr 17 2026

Very Warm and Dry Weather Continues:

A robust mid-level ridge over the Gulf will rebuild over the Southeast US today into Saturday, supporting continued very warm and dry weather. With the center of the ridge axis and warmest airmass set up over Georgia this afternoon, high temperatures will climb into the upper 80s to low 90s, with a very high chance for the earliest 90 degree day on record for Atlanta. Overnight lows tonight will only fall to the low to mid 60s, with temperatures again climbing to the upper 80s to low 90s on Saturday afternoon. The combination of increasing high clouds and ridge axis sliding off to our east will likely keep high temps a few degrees cooler than today. Increasingly breezy southwest winds during the afternoon will provide some relief, unlike today when winds will be very light. Daily temperature records will be threatened both days across the area.

Fire Weather Concerns Persist:

The warm and dry airmass over the region will continue to create fire weather concerns when combined with the very dry vegetation from the ongoing drought. Humidity will drop to around 25-30% across most of the area today, prompting the Fire Danger Statement that will be in effect for this afternoon and evening. Another issuance will be needed on Saturday, especially when factoring the increasingly breezy southwest winds. We will continue to urge people to use extra caution with any outdoor flames or burning as these conditions persist.

LONG TERM
(Saturday night through Thursday)

Weekend Rain For Some:

Ensemble guidance remains aligned on the passage of a stout longwave trough across the eastern CONUS late Saturday through late Sunday. An associated expansive low pressure system will drive moisture advection across the southern U.S. along the system's cold front as it pushes eastward. The result will be showers and potentially thunderstorms across at least parts of north and central Georgia Saturday evening through Sunday morning.
Strong mid-/upper-level winds will accompany the base of the trough swinging through, but given such a dry airmass in place beforehand, the instability/buoyancy necessary for organized/widespread severe weather will be lacking. That said, given the sharp frontal forcing evident in progged surface pressure + precipitable water (PWAT) fields, would not be surprised if a few gusty showers/storms made it into north Georgia before convection weakens as it continues eastward. Given that this week's U.S. Drought Monitor update shows that conditions are the worst thus far since the onset of the drought last fall, appreciable rainfall is desperately needed. Unfortunately, rainfall with the weekend cold front is unlikely to exceed around 0.25 inches (except for perhaps far northwest Georgia)
-- not nearly enough to put a dent in the drought.

Cold Front and Still Dry Early Next Week:

The cold front passage will be noticeable Sunday morning and afternoon for much of the County Warning Area (CWA) as temperatures drop from northwest to southeast. For parts of the CWA, Sunday morning lows and Sunday afternoon highs will be some 10-20 degrees cooler than those on Saturday. Monday morning lows could be as chilly as the upper 30s to lower 40s across parts of the CWA Widespread lows in the 40s are currently forecast for early Tuesday morning. Afternoon temperatures will moderate by Tuesday and Wednesday. Even amid the weekend rain chances, fire weather conditions will continue to bear watching. The post-front environment Sunday through early next week is expected to bring a very dry airmass, with relative humidity currently progged to bottom out in the teens-to-20s percent range (especially on Monday and Tuesday) -- plenty dry enough for continued issuances of fire weather products.
