Evening Update

Issued at 915 PM EDT Sat Jun 22 2024

A few lingering light showers should be coming to an end over central Georgia this evening. A few adjustments have been made, but the short term forecast largely remains on track.

(This afternoon through Sunday)
Issued at 253 PM EDT Sat Jun 22 2024

Relatively uneventful but hot conditions will prevail through the bulk of the short term forecast period. The former Invest 92L is now spiraling inland near Savannah but has brought very little in the way of sensible impact to the area other than some increased cloud cover to southeastern portions of the area. A stout dry layer in the mid and upper levels has largely put the kibosh on any convection in the vicinity of this feature so far this afternoon. PoPs were thus lowered for the remainder of the day in southeastern counties, though an isolated shower or thunderstorm will remain possible over the next few hours.

The main story on Sunday will be the building heat courtesy of the persistent strong midlevel ridge sprawled across the southern US.
Though it will begin retrograding a bit further on Sunday as a trough begins to dig from the Great Lakes into the Northeast US, high temperatures will warm a few degrees as compared to today. As such, highs in the upper 90s are anticipated for the bulk of the CWA outside of the mountains. Sufficient mixing will keep afternoon dewpoints in check and thus keep heat index values below Heat Advisory criteria. Still, heat index values in the upper 90s to as high as 101-102 in east central Georgia will make for a hot afternoon.

By Sunday night, the aforementioned trough swinging into the Northeast will nudge a very weak cold front into north Georgia. A few showers and thunderstorms could develop in association with this front as it pushes southward overnight, but coverage should be fairly limited.


(Monday morning through next Friday)
Issued at 253 PM EDT Sat Jun 22 2024

Biggest changes to the long term forecast package come on Monday.
With our current tropical low stalling out more near the coastline, less moisture looks to be available across the CWA Upper levels remain pretty dry. Overall rain chances have come down a bit. Front is still expected to move towards the area and provide some increased afternoon Tstorm chances, but hires guidance that has come into range is not that excited about coverage, with HRRR PMM guidance showing some limited rainfall streaks.

Beyond that, the heat continues to be the main story. Front won't provide for much if any relief. It's definitely going to be hot, with temperatures in the upper 90s through at least Wednesday. The question remains just how hot. GFS and other guidance continues to show blistering temps, but a look at the forecast sounding reveals some concerns. Models may be really over mixing, a bias we have seen in the past and that has played out already in some other locations this year. Diurnal convection may also have something to say, which would keep temps in line as well if we hit convective Ts, which is still possible. Have continued to blend a little NBM 10th percentile into the max T forecast to keep things a touch lower than raw NBM values. Either way, overnight temps in the mid to upper 70s will provide for little relief from the heat, and max temps approaching 100 will still mean apparent Ts near 105 or higher.

After this, trough is expected to move through the area and provide some relief (hopefully). Still uncertainty around timing, but overall it looks like we should get some rainfall, which is much needed given many areas have 30 day averages that are below 25% of normal.
