Marine Weather and Tide Forecast for Crooked Creek, GA

SHORT TERM
(This evening through Thursday)
Issued at 357 PM EDT Wed Apr 29 2026

With low cloud ceilings lifting and scattering during the mid- morning hours into the early afternoon, temperatures have been able to warm into the upper 70s to low 80s in north Georgia and mid 80s in central Georgia. Highs could furthermore rise into the upper 80s in east-central Georgia in the peak heating hours. With veered surface winds ahead of the cold front and limited large-scale ascent, sustained widespread convection is not expected this afternoon. However, isolated to widely scattered thunderstorms cannot be ruled out in portions of north Georgia, in and to the north of the Atlanta metro where surface heating and convection can overcome weak capping. Thunderstorms that are able to develop could tap into SBCAPE values between 1500-2500 J/kg and 700-500 mb lapse rates between 7.5-8 C/km. So, if we do see storms, a couple of them could become strong to severe in this environment, capable of producing hail and gusty winds.

Tonight, a shortwave will traverse the mid-level zonal flow, overrunning a stalled frontal boundary draped across the northern Gulf Coast. This shortwave will support another system of quasi- organized thunderstorms, which has already begun to develop across southern Mississippi. Hi-res guidance has been coming into better agreement that the system will enter west-central Georgia just before midnight, continuing northeast towards the Atlanta metro and further towards Athens/Gainesville during the early morning hours. A Marginal (level 1 out of 5) Risk remains in effect across central Georgia. Here, slightly greater moisture with dewpoints remaining in the mid 60s and SBCAPE values remaining as high as 1000-1500 J/kg will be favorable for thunderstorm maintenance. A look at hi-res model soundings also reveals the potential for 0-1 km shear of 20-25 kts on the leading edge of the system. Thus, strong, potentially damaging wind gusts will be possible within the strongest storms on the leading edge of the system.

Broken low clouds in the morning after daybreak will begin to scatter out in the late morning and early afternoon. Highs will be cooler than observed today, largely in the low to mid 70s along and north of I-85 and in the upper 70s to near 80 to the south. After trailing showers behind the convective system come to an end across the majority of the area, slight chance to low-end chance PoPs (15- 30%) are anticipated to persist in the far southern tier in the vicinity of the stalled frontal boundary.

LONG TERM
(Friday morning through next Tuesday)
Issued at 357 PM EDT Wed Apr 29 2026

Generally unsettled weather is expected to continue as the long term picks up as the upper level trough finally pushes out Saturday afternoon and into the evening. Most of the activity will be rain, though instability could build across portions of the southern part of the CWA through mid afternoon to result in some thunderstorms south of a line from Columbus to Macon. While widespread severe weather is not expected, a few strong storms could be possible.

High pressure establishes on Sunday and kick off another dry period with building heat. Modest temperatures on Sunday in the upper 60s and low 70s will quickly rebound on Monday as they climb back into the upper 70s and 80s for the remainder of the week. This will be accompanied by drier conditions, with relative humidity falling into the 30% during the afternoon.

Overnight lows Sunday into Monday will be in the low 40s with some upper 30s possible across the higher elevations. Lows will rebound with the Highs and by the end of the week, they'll climb back into the mid to upper 50s.

AVIATION
(18Z TAFS)
Issued at 219 PM EDT Wed Apr 29 2026

Largely VFR conditions are in place across the area as the period begins, with SCT-BKN cu between 030-040 in north Georgia and lesser cloud cover in central GA. Isolated SHRA/TSRA will be possible in north GA this afternoon between 20-24Z, including around the ATL metro sites. More meaningful chances for SHRA (and TSRA for CSG/MCN) return tonight, generally after 04-05Z, advancing from SW to NE. MVFR ceilings are also expected to return around this time, with IFR possible underneath. MVFR ceilings are forecast to persist through Thursday morning in the wake of the precip, scattering and improving to VFR by 15-16Z.
Winds will be SW to W this afternoon, between 8-12 kts with gusts of 18-22 kts. Winds will diminish to 5-10 kts and shift to NW by 00Z, though gusts could return in the vicinity of precip.

//ATL Confidence
18Z Update
Medium confidence on all elements.
