Residents of Northwest Georgia should prepare for a prolonged period of wet weather and high humidity as a very warm and moist air mass, influenced by a tropical disturbance near the Florida Panhandle, settles over the region. A southeasterly flow is funneling copious amounts of tropical moisture into the area, setting the stage for daily chances of showers and thunderstorms throughout the forecast period.

According to the National Weather Service, the extended forecast indicates elevated rain chances and consistent humidity, with specific concerns about localized heavy rainfall.

Detailed Forecast:

  • Tuesday, August 12th: Expect scattered to widespread showers and a few thunderstorms throughout the day, with a 70% chance of rain. Patchy fog is possible in the morning. Temperatures will reach highs in the lower 80s°F and lows in the lower 70s°F. Some storms may produce localized gusty winds, torrential downpours, and frequent lightning.
  • Wednesday, August 13th: The chance of showers and thunderstorms continues, particularly in the afternoon, with another 70% chance of rain. Highs are forecast to be in the upper 80s°F.
  • Thursday, August 14th: The likelihood of rain decreases slightly to a 50% chance of showers and thunderstorms, mainly in the afternoon. Temperatures will remain warm, reaching highs in the upper 80s°F.

Specific Concerns:

The primary concern for Northwest Georgia is the potential for locally heavy rainfall. The National Weather Service warns that the high moisture content in the atmosphere, combined with the possibility of “training storms” (where storms repeatedly move over the same area), could lead to localized instances of heavy rainfall and potential nuisance flooding in low-lying areas and spots with poor drainage.

While some individual storms may bring gusty winds and frequent lightning, widespread severe weather is not anticipated. The NWS notes there is limited instability in the atmosphere, reducing the threat of widespread severe thunderstorms.

Temperature Trends:

Throughout the week, temperatures will remain warm and consistently humid, with highs primarily in the mid to upper 80s°F and overnight lows hovering around 70°F. Temperatures are expected to gradually return to normal for this time of year by mid to late week.

Residents are advised to stay informed about weather updates, especially if planning outdoor activities, and to exercise caution on roads where heavy downpours could reduce visibility or cause localized flooding.
