Forecast Discussion 9:17 AM Wednesday, October 14, 2026 Potential Hazards Friday…Wind gusts 30-35 MPH in the late afternoon and night Saturday…None Sunday…Wind gusts 15 to 25 MPH Changes to the Previous Forecast Minor tweaks to the timing of the winds. General Discussion No major changes to this forecast. I’ve made some minor tweaks to the timing of the winds Friday through Sunday. The strongest winds will be associated with the passage of the cold front. The models are in good agreement with bringing the front across the race course between 4 and 6 PM Friday. There could be a few sprinkles immediately behind the front, otherwise it will be dry. However, as the cold front passes, the winds will increase to 15 to 30 MPH, with a few gusts to 35 MPH. These winds will continue into the evening hours and possibly after midnight Friday night. The strong winds will diminish somewhat on Saturday, but increase again by Sunday afternoon with wind speeds of 15 to 25 MPH. An Infield Weather Advisory for Winds will likely be needed Friday afternoon and night… and also on Sunday. An Infield Weather Advisory is to alert the infield of the good potential for the following… Winds (sustained or gusts) greater than 15 MPH Thunderstorm wind gusts greater than 15 MPH and Lightning Heavy rain of 0.50” or greater by @ambweather

Forecast Discussion 8:57 AM Monday, October 12, 2026 Potential Hazards Friday…Wind gusts 15 to 25 MPH in the late afternoon and evening Saturday…Wind gusts 15 to 20 MPH in the afternoon Sunday…Wind gusts 15 to 20 MPH in the afternoon Changes to the Previous Forecast Minor tweaks to the timing of the cold front and onset of the gusty winds on Friday. General Discussion The forecast remains mostly unchanged with a few minor tweaks to the timing of the cold front on Friday. This will push back the gusty winds until later in the afternoon and evening. There is still a risk of a late day shower with the front, but amounts will be light, if any. It will become windy both Saturday and Sunday afternoon along with much cooler temperatures. An Infield Weather Advisory for Winds may be needed Friday through Sunday.

Forecast Discussion 6:44 PM Sunday, October 11, 2026 INFIELD WEATHER ADVISORY THIS TODAY Potential Hazards Friday…Wind gusts 15 to 25 MPH Saturday…Wind gusts 15 to 25 MPH Sunday…Wind gusts 15 to 20 MPH General Discussion A mostly dry forecast for this week with a significant change by the weekend. The week will start out sunny with above normal temperatures, but that will change by the end of the week. A strong, but mostly dry cold front will move across the state on Friday. There is an outside chance of a shower in the afternoon associated with the cold front, otherwise it will be dry. The main story will be the much colder temperatures and the windy conditions. While temperatures are not expected to drop significantly on Friday, the weekend temperatures will be considerably colder than what we have experienced so far this season. It will also become windy Friday afternoon and Saturday afternoon with wind gust in the 15 to 25 MPH range. It will continue to be windy on Sunday, however at this time I do not expect any wind gust greater than 20 MPH Sunday afternoon. An Infield Weather Advisory for Winds may be needed Friday through Sunday. An Infield Weather Advisory is to alert the infield of the good potential for the following… General winds (sustained or gusts) greater than 15 MPH Thunderstorm wind gusts greater than 15 MPH Heavy rain of 0.50” or greater by @ambweather

Forecast Discussion 10:34 AM Thursday, October 8, 2026 …HURRICANE ISAIAS WILL IMPACT THE GEORGIA CYCLING AREA SATURDAY… Hurricane Isaias, currently a Cat 1 hurricane over the central Gulf, will strengthen and move north northeast today and Friday, making landfall Friday evening along the Alabama/Extreme Western Florida Panhandle. It will then make a slight turn to the north northwest Friday night and move over western Alabama and into Tennessee on Saturday. Although the center Isaias will be well west of Georgia, its impacts will be felt across the Georgia Cycling area. Rain, heavy at times will spread across the state Friday night and Saturday. The heaviest rain will fall over the extreme west and north parts of the state where 2 to 4” of rain are likely, with 1 to 2” elsewhere. Winds will increase late Friday and Saturday with sustained winds of 25 to 35 MPH on Saturday, although a few higher gusts are likely, mainly in the rain bands. I can’t rule out an isolated tornado on Saturday in the stronger rain bands. All of this will clear out from west to east on Sunday.

General Discussion An Infield Weather Advisory is now in effect beginning Friday afternoon and continuing into Sunday for the following… Friday…thunderstorm wind gusts in the afternoon and evening Saturday…thunderstorm wind gusts in the afternoon and evening, and rainfall greater than 0.50” Saturday night Sunday…rainfall greater than 0.50”, mainly in the afternoon The models are coming together again and are showing a little more moisture. They are also bringing in the moisture a little earlier on Friday and for that reason I’ve raised the chances of thunderstorms Friday afternoon. While there will be showers and thunderstorms scattered throughout the day Saturday and Sunday, there will be a couple of main waves of rain moving across the race course that will bring in more numerous showers and thunderstorms. The first will move across the area late Saturday afternoon and into Saturday evening. The second will move across the area Sunday afternoon. General rainfall amounts will be between 0.75” and 1.25”, however any heavy rain band could produce rainfall in excess of 1.50”. An Infield Weather Advisory is to alert the infield of the good potential for the following… General winds (sustained or gusts) greater than 15 MPH Thunderstorm wind gusts greater than 15 MPH Heavy rain of 0.50” or greater by @ambweather

Forecast Discussion 9:35 AM Wednesday, September 30, 2026 Potential Hazards Friday…scattered thunderstorms Saturday…scattered thunderstorms in the day, numerous thunderstorms at night Heavy rain possible Sunday…scattered thunderstorms Changes to the Previous Forecast Increased the chances of rain Saturday and Sunday. General Discussion Once again the models are diverging with the forecast and this has brought some uncertainty in the timing of the rain and the rainfall amounts. I’ve gone with a consensus which is pretty close to the current forecast. I raised the chances of rain both Saturday and Sunday, but it should be noted that the best chance of rain on Saturday will come in the mid to late afternoon hours, then increasing during the evening as a backdoor front moves out of South Carolina and across the racecourse. The main upper level energy will move across the racecourse Sunday and this will keep rain likely during the day with just a chance of thunderstorms. Sunday could be more of a rain event versus a thunderstorm event, and therefore I keep the chances of thunderstorms in the Yellow category. An Infield Weather Advisory may be needed for Saturday afternoon through Sunday. An Infield Weather Advisory is to alert the infield of the good potential for the following… General winds (sustained or gusts) greater than 15 MPH Thunderstorm wind gusts greater than 15 MPH Heavy rain of 0.50” or greater by @ambweather
