SHORT TERM
(This evening through Saturday)
Issued at 308 PM EDT Fri Jul 26 2024
The region continues to be sandwiched between a weak upper low to the west and ridging to the east thus keeping the gravy train alive through at least Saturday. Models pinching off an upper low across the the East coast this weekend which in turn flattens out the Atlantic ridge a little by Saturday. A weak surface ridge tries to wedge in from the NE tonight and really only results in a slight wind shift out of the NE, but the very moist/high PWAT airmass won't budge, thus we will be socked in with a warm and humid short term much like this past week. Without any real focus, shower and thunderstorm activity will be a bit more limited today and Friday and guidance generally agrees with this notion despite the very high PWAT atmosphere. Expect diurnal shower and storms to be prevalent each day mainly after 2pm.
Friday AM looks to be another low cloud kind of start. Model cross sections consistent in depicting a saturated column from the surface up to 500mb so could be another repeat of this morning...particularly for northern GA including the metro. Will need to keep a close eye on fog formation overnight as well. Winds look to go calm with dewpoint depressions of less than 2 deg pretty much area wide should yield some fog..esp in areas which receive some rain today or areas where the ground is still wet.

LONG TERM
(Sunday morning through next Thursday)
Issued at 308 PM EDT Fri Jul 26 2024
Very little change to the forecast package this afternoon. Still some questions around the ability of the CAD wedge to make it to the CWA, as some guidance today is trying to wrap the dry air a bit more around the surface and upper level low that cuts off over the western Atlantic. See previous discussion below.

The extended period begins on Saturday night with a highly amplified pattern. An upper level ridge will extend from the northern Gulf towards the Great Lakes region while a closed low develops off the Atlantic coast. Overnight, surface high pressure associated with the ridge will set up over the Appalachians. As this occurs, a CAD wedge is anticipated to build into far northeast Georgia. The influence of the low to the east could furthermore enhance CAD-like feature. If this setup comes together, it could bring relatively drier air to portions of east Georgia on Sunday. Here, dewpoints would lower into the upper 60s as opposed to the mid 70s. Precipitable water values in east Georgia would also lower to between 1.5 to 1.8 inches, compared to nearly 2 inches across the remainder of the forecast area. Over the course of the day on Sunday, a shortwave trough will swing northeastward through the Midwest, dampening the aforementioned ridge. The shortwave will also provide forcing for showers and thunderstorms, which will be enhanced by diurnal instability. At this time, likely PoPs are being carried in much of central and west Georgia by Sunday afternoon, with chance PoPs in east Georgia where the drier air is anticipated.
On Monday, the shortwave disturbance will pass to the north of Georgia, which will scour out any wedge feature over northeast Georgia and return ample moisture and high dewpoints to the whole forecast area. With deep atmospheric moisture combined with forcing near the shortwave, PoPs are forecast to range from 60-80 percent across the majority of the area on Monday afternoon, with the highest chances across the far north. Areawide, diurnally driven convection is expected to continue each day from Tuesday through the end of the period. Rainfall totals will be dependent on storm formation locations, but the heaviest rain capable of producing flooding concerns will be most likely across north and west Georgia through Monday. With a broad ridge setting up over the western CONUS at this time, much of the Southeast will be underneath a northwesterly flow regime on the "dirty" side of the ridge. This regime could favor increased shear and chances for organized thunderstorms, and will thus need to be monitored. Increased cloud cover will keep high temperatures limited to the 80s on Sunday through Tuesday. Large scale moisture levels are forecast to gradually decrease starting Tuesday into mid-week. At this time, more scattered cloud cover will allow high temperatures to return to the low to mid 90s by the end of the period.

(00Z TAFS)
Issued at 746 PM EDT Fri Jul 26 2024
Isolated shra/tsra persist across portions of Central GA this evening including metro ATL. Activity should diminish within the next hour or two. Given the late arrival and lack of much rainfall today the opportunity for lower IFR cigs to develop overnight (09-13z) is now much lower. Kept the mention of a SCT IFR deck around 10z for most locations but will continue to monitor trends over the next few hours. Winds, currently NNW, look to largely become VRB overnight (<4kts) and shifting solidly to the NE by 12z. ISO/SCT shra/tsra on Saturday beginning as early as 19z.
//ATL Confidence
00Z Update
Medium confidence on the occurrence of IFR cigs and timing/occurrence of tsra on Saturday.
High confidence on remaining elements.
