Coolest Air of the Season Coming Monday Morning

We got down to 58 degrees this morning in Atlanta. It was even cooler outside the city with some low to mid 50s for wake up temperatures. We got up to 81 this afternoon with low humidity and plenty of sunshine.

It has been cooler already this year. So far, the coolest temperature this month has been 54 degrees on the 19th. The first cool snap on 9/9 got us down to 59. We will have the coolest air so far this season Monday morning. Morning temps will be down to 51 degrees in Atlanta. It will be in the 40s outside the city. It will definitely feel like Fall!

The WIZometer will be up to an 11 again Monday. As temps return to the 80s, the WIZometer will go back to a 10 Tuesday and Wednesday with a few more clouds mixing in and temperatures warming back to the 80s. We aren't finished with the warm weather yet. We will get back to the mid 80s on Thursday and Friday.

Enjoy the sunshine, low humi

Cold Front now south of Atlanta-Temps Cool Overnight

The cold front is now south of Atlanta. Our winds have shifted. The wind is now coming from the northwest. That northwest flow will continue to usher in the cooler air overnight. We will drop into the upper 50s in Atlanta. Many areas outside of Atlanta will get down to the low to mid 50s. We'll even have some 40s in north Georgia.

Our afternoon temperatures on Sunday will be running about 8-10 degrees cooler than it was on Saturday. Saturday's high was 87. It will be 78 on Sunday. We will also have a little breeze from the NW at 10-15mph with an ocassional gust to around 20mph.

Cold Front on the Way

A cold front is on the way! It is moving into northwest Georgia this afternoon. It will continue to move to the south and east. This front is the leading edge of some cooler air that will move in tonight. The front will be south of Atlanta by 7pm. We will begin to feel the cooler air moving in tonight.

Fall arrived at 10:49 this morning with the Autumnal Equinox. It still felt like late summer today with temps getting into the low to mid 80s this afternoon. Sunday will be the first full day of Fall. It will feel more like fall with wake up temperatures in the upper 50s and afternoon highs in the upper 70s. It will also be a little breezy with a northwest wind at 10-15mph. The air will also be much drier with dewpoints dropping into the 40s. That means the relative humidity will be low on Sunday.

First Day of Fall Means Northern Lights?

First Day of Fall Means Northern Lights?

Aaah the first day of fall. Colorful leaves, pumpkins, and cool temperatures are what many of us associate with fall. But you likely forgot one big one….the northern lights. Yes, that’s right. For reasons scientists don't fully understand, the days around the equinoxes are twice as likely as other times of the year to have geomagnetic storms.

"Statistically, we see an increase in the amount of auroral activity, the intensity, and the location of the aurora, but we really don’t understand why that is," explains Carol Paty, a professor at Georgia Tech. "Most likely part of the explanation probably comes in the geometry of the magnetic field of the Earth as it interacts with the solar wind magnetic field."

So does that mean we have a chance to see some northern lights here in Georgia?

“Unfortunately, probably not," Paty says. "We’re a little too far south, unless there’s a very, very energetic or very active solar storm event.”

Fall Begins Saturday-Feels Like Fall Sunday

Fall Begins Saturday-Feels Like Fall Sunday

Today was the last day of summer. Fall begins Saturday at 10:49am. It is the Autumnal Equinox. It will still feel like summer Saturday as high temps will still get up to 84 in the afternoon. A cold front is on the way. It will sweep through during the afternoon hours. After the front moves through, the cooler air will start to move in. It will begin to cool down Saturday night. We will wake up Sunday morning will temps in the 50s and afternoon highs in the 70s. So the first FULL day of Fall will actually feel like Fall.

This looks like a relatively dry front moving in. We will have a few more clouds building in the afternoon as the front approaches. There is less than a 20% chance of a light shower. Most areas will stay dry. If any drops fall out of the clouds, they would be brief and light.

Although the last week brought a drop in temps, the Fall season officially begins this weekend, and you can view it in a special way this year. There will be a special webcast today to help celebrate the event.The online Slooh Space Camera, which broadcasts live views from telescopes around the world, will stream shots of the sun Friday beginning at 4 p.m. EDT. The free show is in honor of the September equinox, which on Saturday (Sept. 22) rings in the Northern autumn and the Southern spring.

Slooh will also air telescope views of the moon during the webcast to mark International Observe the Moon night, which falls on Saturday this year as well.
