Marine Weather and Tide Forecast for Rest Haven, GA

SHORT TERM
(Today through Thursday)
Issued at 440 AM EDT Wed Jun 17 2026

Well, we've got some "fun" in store for us here in north and central Georgia over the next few days. The short term discussion is going to cover through Friday in order to capture the window of best impacts over the CWA The bottom line up front is that heavy rain is expected to impact north and central Georgia starting as early as Thursday morning and carrying well into Friday. A Flash Flood Watch is in effect from Thursday morning until very early Saturday for multiple rounds of heavy rainfall with widespread rainfall totals of 2-4" with locally higher amounts that could exceed 5". Both flash flooding and some riverine flooding will be possible.

Let's start with the now. A shortwave is exiting to the northeast of the area early this morning. The stream of high moisture transport moving into the surface and upper level lows has mostly stalled over us keeping showers around the area from approximately the metro to points south. These should slowly come to an end as the system quickly pushes to the east by sunrise. Sunshine may be able to break out across portions of north Georgia this afternoon. With a broad surface high sitting off the Florida coast, southwest winds will send surface moisture streaming right back into the area. Expect some storms to form across central Georgia with a few able to make into parts of the metro.

Thursday is where the real "fun" begins. Synoptically, we've got several players coming together to make this possible. In the upper levels, an anticyclonic rossby wave break has occurred over the top of the subtropical ridge sitting across the southern tier of the CONUS. This has squeezed an area of lower PV air into an extended streamer. Simultaneously, we've got a potential tropical system sitting just off the Texas coast in the Gulf that will be feeding on the already warm waters. This system essentially rides that PV streamer to the north and east right into us, following both it and a frontal boundary draped to the north across the Ohio River Valley.
The remnants of the potential tropical system/tropical wave moves across us on Thursday bringing heavy rainfall and the potential for some severe weather.

On Friday, strong, broad surface low is located over the NE and eastern Canada with the front draped just to the north. High moisture content continues to sit across the area and moisture continues to pool ahead of the front which may push slowly southward. Another round of convection blows up either early Friday morning or in the afternoon, depending on the guidance being looked at. This has the potential to dump yet another round of heavy rainfall via widespread thunderstorms on the CWA after having received quite the drenching the previous day. That said, a bit more uncertainty on how this day plays out, especially given the complexities of the previous day.

A couple of caveats to mention for the above, especially on Thursday. Some of the late evening and morning CAMs have been showing an MCS thunderstorm complex forming as the surface tropical low pushes across AL towards us Thursday morning into the afternoon.
In such a scenario, heaviest rainfall gets shunted further south, and the morning NBM QPF bears that possibility out within the mean, keeping the broader axis of highest amounts to more southern Georgia. This scenario would lead to more limited flooding impacts for our CWA (not complaining). However, 90th percentile QPF (broad 4-5") shows the other possibility, where convection is focused around the low itself and is more isolated out ahead of it. This scenario likely delivers the heaviest rainfall to our area, and the isolated convection would be a severe concern with the potential for some mini-supercells. SRH across several CAMs is sufficient at ~100 m2/s2 in the CWA, and may be underdone a bit. Depending on the timing of the system, day time heating may allow for CAPE to rise to 1500-2000 J/kg as well. Storms may be capable of some strong to severe winds, and you can't rule out an isolated tornado or two given the potential environment.

LONG TERM
(Thursday night through Tuesday)
Issued at 440 AM EDT Wed Jun 17 2026

Tropical moisture will linger over the area Friday night, even as the remnants of the tropical disturbance push to our east. Expect that shower and thunderstorm activity may be slow to diminish overnight but will gradually push southward into the day on Saturday ahead of a cold front dropping into the state. Drier air will push into at least the northern half of the area during the day Saturday, but showers and storms may linger across portions of central and southern GA through Saturday afternoon.

At least low chances for showers and storms will remain in the forecast Sunday into early next week as surface moisture returns to the area, though a lack of synoptic forcing will likely keep activity isolated-scattered. Temperatures will remain near or slightly above average through early next week as low-amplitude upper ridging builds back into the area.

AVIATION
(06Z TAFS)
Issued at 153 AM EDT Wed Jun 17 2026

IFR cigs in place across the metro TAF sites with occasional bounces to MVFR. DZ remains in place and will slowly end through the night. Cigs may lower even further, especially as drizzle comes to an end, bringing some LIFR conditions at least temporarily before sunrise. Gradual improvement expected through morning with some clearing by afternoon. Small chance of some evening TSRA. Cigs expected to build back in Thursday morning before sunrise. Winds will pick up through period from west side, 5-10 kts, with some gusts possible.
