Scattered Rain Showers Are Forecasted For Central Georgia; Colder Temperatures in Northern Georgia

Bryan Dijkhuizen

As the morning hours begin, the cold front has passed into east-central Georgia, with a few lingering isolated showers continuing ahead of the frontal boundary as the day progresses.

The front is predicted to move through south Georgia and then out of the forecast region by daylight on Wednesday. As a result of the front, northwesterly winds are beginning to flow into the area, clearing the sky and bringing in a colder and drier air mass.

Low Temperatures

Low temperatures are predicted to dip into the 30s and low 40s in north Georgia (with possible upper 20s in the higher altitudes of far northeast Georgia), and mid-40s to low 50s in central Georgia, where colder air will arrive later in the day than in north Georgia.

In contrast to the last few days, afternoon highs today will be more seasonal, ranging from the low to mid-50s in north Georgia to the upper 50s to low 60s in central Georgia, with temperatures running approximately 3-6 degrees below climatological normals.

It is projected that the front will stall over south Georgia while the underlying low-pressure system swiftly advances northward towards eastern Canada.

The front will be almost perfectly aligned with the upper-level flow. Because of a shortwave across the southwesterly flow above, the colder, more seasonal conditions will only last for a brief period before low-level winds change to an easterly direction, allowing for the progressive advection of Atlantic moisture into the predicted region.

Light Rain Showers

Because of the impending arrival of the shortwave above disturbance, cloud cover and scattered light rain showers will increase throughout central Georgia, particularly in the areas closest to the stationary front, starting late this afternoon.

Across the region, there is little to no instability forecast today, and thunderstorms are not expected as a consequence.

The stalled front will slowly drift northward throughout tonight and into Wednesday morning, settling over middle Georgia and enabling many showers and gloomy skies to creep northward.

Thunderstorms are unlikely to occur on Wednesday due to the lack of instability throughout the night and into the next day.

In addition, as it moves through the predicted region, the disturbance will be superimposed over the frontal boundary, increasing low-level air moisture levels.

As a result, it is projected that precipitable water values would range between 1.2 and 1.4 inches by Wednesday morning.

Rainfall totals are expected to range from 0.25 to 0.5 inches to the south of the I-20 corridor, decreasing amounts to the north of the highway corridor. Periods of moderate rain might locally result in more significant quantities, although flooding is not expected to be a problem.

Towards the middle of Wednesday afternoon, the shortwave will pass across Georgia.

The northwesterly flow above will allow for another brief period of colder and drier air to transition into the extended phase.
