UPDATE

Issued at 931 PM EDT Wed Apr 2 2025

Isolated storms have largely dissipated across our forecast area at the time of this writing. Overall coverage was a little higher than anticipated across southeast and eastern GA as there was plenty of surface instability to work with and convection further north had the wedge boundary to work with. With southerly/southeasterly flow overnight anticipating development of low clouds again overnight through early Thursday. Some locations may see some patchy fog -- namely locations where showers or thunderstorm occurred this afternoon. Mild temperatures expected overnight -- lows in the mid to upper 60s.

SHORT TERM

(This afternoon through Thursday) Issued at 202 PM EDT Wed Apr 2 2025

Primary forecast concern is actually unseasonably warm temperatures that will likely break all-time daily records.

Wedge still holding strong in far NE counties, but otherwise warm and breezy today with less showers and storms than expected so far. Only light showers observed are in upstate SC at this time.

As noted, main talking point are max temps likely breaking daily all-time records the next 3 days (Thursday, Friday, Saturday) and again on Sunday over eastcentral counties south and east of Macon. As for Thursday, max temps should exceed 90 in a few spots in Middle GA. Already saw some spots reach 90 this afternoon which was a bit above NBM guidance.

While we will not reach any official heat advisory criteria using the heat index, the NWS HeatRisk product that is based on max and min temperature and how it compares to climatology for this time of year is indicating that some areas of Middle GA will be in the Orange or Moderate level (level 2 out of 4) of heat-related impacts over the next 3 days. Those who are vulnerable to heat or outdoor workers with health concerns may be at risk.

As for precip, expecting even lower chance of showers than we had today over far NE GA tomorrow. Any rain that does fall will be light with amounts less than 0.05 inch.

LONG TERM

(Friday morning through next Tuesday) Issued at 202 PM EDT Wed Apr 2 2025

Very Warm To Record Breaking Heat Through Saturday:

Heat will be the story through Saturday as an anomalously strong 500 mb mid to upper level ridge sets up over the eastern US, extending north from the Caribbean. The associated strong surface- 850mb ridging will be parked to the east over the western Atlantic, with stout south-southwesterly winds pumping warm and humid air across Georgia. High temperatures will be in the upper 80s to low 90s on Friday and Saturday. These temps are nearly 20 degrees above normal for this time of year, and overnight lows will follow suit, only dropping to the 60s each night. All climate sites could see record breaking max and min temperatures both days.

Showers and Thunderstorms Return Sunday into Next Week:

As we head into Sunday, a strong trough over the central US will move east and start to kick out the ridge. A cold front associated with this trough will slowly push through the region Sunday into early Monday, bringing along widespread showers and thunderstorms. There is potential for strong to severe storms along and ahead of the front as there will be plenty of shear in place, but instability looks to be a limiting factor yet again. SPC has a 15% severe weather outlook for most of Georgia on Sunday. Due to the convective activity and slow moving nature of the front, localized flooding may also become a concern. Following the cold front, much cooler temperatures and dry air will move into the region through the middle of next week.

AVIATION

(00Z TAFS) Issued at 734 PM EDT Wed Apr 2 2025

VFR expected to give way again to MVFR-IFR cigs after 09z given persistent southerly flow. Lowest cigs expected at KAHN, where patchy LIFR will be possible between 10-13z -- especially considering an isolated tsra passed over the airfield this evening. Winds switch from the east to west side between 15 to 18z Thursday with gusts picking up to 18 to 22kts through the aftn. Cigs expected to lift to VFR after 18z. An isolated shra/tsra cannot be ruled out tomorrow (mainly for KAHN) but chance is too low to mention in TAF at this time.

//ATL Confidence...00Z Update...

Medium confidence for IFR cigs. High confidence remaining elements.
