At a glance:

- Unseasonable warmth continues

- Isolated to scattered afternoon thunderstorms return

Sensible weather for the remainder of the weekend will continue to be governed by a strong (~2.5 sigma above average, per ensemble guidance) -- albeit retrograding -- mid-level ridge. At the surface, weakening high pressure will give way to relatively ambiguous low- level flow. Previously deemed Invest 92L has since moved inland over southeast Georgia, bringing with it increased cloud cover and a slug of tropical moisture to break up our otherwise dry airmass.
Associated impacts will be relatively benign, with 30-50% chances for showers and thunderstorms for areas south and east of Macon, and highs just a tick lower in the aforementioned areas this afternoon (1-2 degrees; still in the lower-90s).

On Sunday, expect summertime, diurnally-driven convection, primarily across the southern and eastern portions of the forecast area, given forecast PWATs north of 1.7" (~90th percentile for late June per SPC's sounding climatology) and highs reaching well above convective temperatures.

After several days of moderation under subsidence and clear to mostly clear skies, highs through Sunday will be sufficiently warm.
Today, expect temperatures to surge into the lower-to-mid 90s for all but the terrain of northeast Georgia, which will remain in the 80s. Tomorrow, highs will be a few degrees warmer, in the mid-to- upper 90s areawide. Improved moisture will allow for trends toward "air you can wear" for Sunday, and heat index values will likely breach the triple digits (as high as 102F) east of a line extending from Macon to Athens. Be cautious if spending long periods of time outside on Sunday, and take frequent hydration breaks in the shade.


(Sunday night through Friday)
Issued at 345 AM EDT Sat Jun 22 2024

As the extended period begins on Sunday evening, upper level troughing will be setting up over the northeast CONUS. Meanwhile, a surface low associated with this trough will extend a cold front southwestward into the Tennessee Valley region by Sunday night. A shortwave dropping through the Great Lakes region will serve to amplify the trough, which will also give the front an additional southward push towards north Georgia. As this occurs, scattered showers and thunderstorms will spread into far north Georgia on Sunday night, advancing southward through the overnight hours and into Monday. The front is likely to stall in during the afternoon on Monday without providing much change in the weather conditions. High temperatures are forecast to rise into the low to mid 90s in north Georgia and upper 90s in central Georgia. Diurnally-driven thunderstorms on Monday afternoon will be highest in coverage to the south of the front where the most atmospheric moisture will remain.
Relatively lower dewpoints (in the mid 60s) are anticipated behind the front on Monday night into Tuesday. A 500 mb ridge will move advance towards the eastern CONUS on Tuesday, with surface high pressure setting up over the Appalachians. Drier air underneath this pattern will be short-lived, as diurnally-driven convection will return on Tuesday afternoon and occur once again on Wednesday.

It will be important to keep an eye on temperatures throughout much of the week. NBM guidance continues to show temperatures in the mid to upper 90s across the majority of the forecast area, and some locations in east-central Georgia reaching above 100 in portions of east Georgia Monday through Wednesday. For this forecast package, I elected to blend in NBM10percent guidance into the high temperature guidance. As convective temperatures are reached and storms subsequently develop, the rain and increased cloud cover can often prevent us from reaching such high temperatures. Regardless, even with trending high temperatures down, they are still forecast to range from between 6-12 degrees above average for late June and still rise into the mid to upper 90s each afternoon. With more moisture than the previous spell of heat, so heat indices are forecast to creep up into the triple digits, and heat products may be warranted. Overnight lows are also not anticipated to provide much relief falling into the low to mid 70s.

By late Wednesday, the ridge will shift eastward off the Atlantic coast as a longwave trough extends from the eastern Great Lakes towards the Lower Mississippi River Valley. Model guidance continues to indicate an associated frontal system approaching Georgia on Thursday, but uncertainty remains with respect to timing and strength. Maintained high-end chance to low-end likely PoPs late Wednesday into Thursday to account for increased precip chances ahead of a potential front, but also reflect lingering uncertainty.

VFR conds to continue thru the TAF pd. Brief AM low-MVFR to IFR psbl for AHN/MCN. Otherwise, expect FEW-SCT cu at 4-6kft from 15Z on. Pcpn chcs at northern sites currently too low for TAF mention. Winds to remain light (7kts or less) out of the E to ESE, and may be VRB at times when speeds are less than 4kts. A shift to SW winds is likely around daybreak (10-11Z) tomorrow.
