$$What forecasters said that day
The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Atlanta, GA wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 4, 2:00 PM EDT, 3 hours 27 minutes earlier. Its key messages:
- Dangerous heat continues through this evening with heat index values up to 106 possible. A Heat Advisory remains in effect.
- Isolated thunderstorms will pose a risk for lightning and gusty winds thru 10PM tonight.
- Elevated temperatures and the chance for thunderstorms each afternoon will continue from Sunday through much of next week.
Area forecast discussion, Jul 4, 2:00 PM EDT, 3 hours 27 minutes before
Area Forecast Discussion National Weather Service Peachtree City GA 200 PM EDT Sat Jul 4 2026 ...Afternoon Area Forecast Discussion... .KEY MESSAGES... - Dangerous heat continues through this evening with heat index values up to 106 possible. A Heat Advisory remains in effect. - Isolated thunderstorms will pose a risk for lightning and gusty winds thru 10PM tonight. - Elevated temperatures and the chance for thunderstorms each afternoon will continue from Sunday through much of next week. && .SHORT TERM... (This afternoon through Sunday) Issued at 155 PM EDT Sat Jul 4 2026 A very warm and humid airmass remains in place across North and Central Georgia this Independence Day. Heat and the chance for thunderstorms will continue to be the primary weather concerns in the short term period. Largely expecting less coverage of showers and thunderstorms through the afternoon compared to yesterday. A remnant outflow boundary now near the TN/GA border and orographic influence has acted as a source of lift for storms in North GA. Additionally, a differential heating boundary, seen on satellite by a Cu field, is/will drive storm development in Central GA. Any storms that form are likely to be slower moving, producing gusty winds and frequent lightning. Outside of any thunderstorms, temperatures will climb back into the mid to upper 90s with heat indices in the 98 to 106 range. Please be mindful of the heat and keep your eyes to the sky as you enjoy any outdoor festivities. A Heat Advisory remains in effect for most of North GA through 8PM this evening. Some of the latest hi-res guidance do suggest lingering showers and thunderstorms even after dark (between 8PM to 2AM), including in and around Metro Atlanta. Certainly not out of the realm of possibilities and definitely something to monitor as festivities and fireworks will be ongoing at this time. Expecting an increase in shower and thunderstorm coverage on Sunday, especially over North Georgia, as an approaching mid-level trough acts to increase SW flow aloft. A surface low and attendant cold front will also be pushing southeastward acting as an additional lifting mechanism for storm development. A few strong to severe thunderstorms, capable of producing damaging winds up to 60 MPH will be possible as the frontal boundary interacts with the moist unstable airmass that will already be in place. The SPC has painted a Marginal Risk (Level 1 of 2) area across much of North GA for Sunday. Elsewhere (i.e. Central GA), convection will be more diurnally driven and scattered in nature. Timeframe for highest coverage of storms looks to be between 2-10PM, though it is summertime and spotty pop-up showers and thunderstorms could begin earlier and linger later. Forecast temperatures on Sunday will be comparable today with forecast highs in the 90s outside of the NE GA mountains and lows in the 70s. Heat indices will still range from the upper 90s to low 100s with the highest values over parts of Central GA. Opted to hold off on another Heat Advisory given the uptick in precip chances and cloud cover tomorrow. Regardless it will be hot and additional heat headlines may be warranted in the future. && .LONG TERM... (Monday morning through next Friday) Issued at 155 PM EDT Sat Jul 4 2026 The upper level pattern looks to remain quazi-zonal through the new week, with some troughing forecast in the Southeast as high pressure becomes elongated. Summer time heat and daily thunderstorm chances hold as the primary highlights of the extended period. A slight down trend in ambient temperatures continues Monday onward with highs in the 90s, barring our mountain zones. Low temperatures and average dewpoint temperatures should also stay in the 70s next week. Given our high relative humidity trends, heat index continues to be the primary concern for the coming days. While most locations in the CWA should host maximum heat indices between the upper 90s and lower 100s, a few locations, mainly across the SE, may still experience heat index values over 105 degrees. Despite most temperatures being just below advisory criteria, impactful heat is still expected daily and areawide. Continue to practice heat safety for the coming days. Trends of diurnally driven convection continue every day of the long term period. LREF ensemble guidance shows a higher concentration of QPF in NW Georgia this week compared to the rest of the FA. This is also reflected with NBM PoPs as they consistently favor this area for likely (55-75%) rain chances. Meanwhile, storm coverage for the rest of the region may be more isolated than scattered. && .AVIATION... (18Z TAFS) Issued at 114 PM EDT Sat Jul 4 2026 Mostly VFR at all sites through the period. SCT Cu at 4-6kft has developed and will persist thru 00z with iso to sct tsra chances thru 02z. May linger past 02z around metro so will monitor. WNW to WSW wind 4-8kts and iso gusts with any tsra. Better coverage of shra/tsra expected tomorrow after 16z. //ATL Confidence...18Z Update... Medium confidence on tsra. High confidence on remaining elements. 07 && .PRELIMINARY POINT TEMPS/POPS...
