Sunday Atlanta Weather Outlook

We had a high temp of only 82 degrees Saturday.  That's 7 degrees below average!  The average high for Saturday's date is 89 degrees.  We also only had a few light showers.  The official rain bucket at Hartsfield-Jackson only got a trace of rain Saturday.

Temps by Sunday morning go down to 68.  A cold front moves in  then stalls out just south of Atlanta.  Our rain chance on Sunday is going to be less than 20%.  Some drier air will filter in.

You will really notice that drier air on Monday and Tuesday as our relative humidity will be much lower.  Folks from Atlanta northward will get to enjoy that, while some areas south of Atlanta will still hold on to some rain chances.  All of us will have a better chance of rain by Wednesday and Thursday. 

Saturday Atlanta Weather

A weak system is moving our way today that will help to kick up just a few scattered showers this afternoon.  The system isn't that impressive.  It won't be a rainout today.  Just watch for a couple of showers to pop up this afternoon.  Temps will move up to the mid 80s.

Changes begin Sunday as drier air filters in.  We will have decreasing clouds Sunday with the rain chances well to the south and east.  That drier air will stay with us Monday and Tuesday, too.  That means a much lower relative humidity as dewpoints will be in the 50s Monday and Tuesday!

The rain chance returns Wednesday and Thursday as we move back to the pattern with afternoon and evening rain chances.

Atlanta Weather | Weekend Forecast

There have been quite a few strong pop up t-storms this afternoon across the metro area this afternoon, all have remained below severe limits. There was one cell in parts of Henry and Butts county earlier that was putting down around 60 lightning strikes per minute!!! These afternoon pop up t-storms are due to the intense humidity and the fact that there is an area of moisture convergence that runs right through the center of the state. These shower and a few storms will continue to fire right along this line until around 7pm, after that things will calm down. More rain in the forecast tomorrow, check out the 6pm news for the full blown hour by hour analysis of Saturday and Sunday. I will also have the weekend forecast on the blog later tonight.

Temperatures to plunge to upper 50s this weekend

ATLANTA -- Low temperatures are forecast to get down into the low 60s Sunday night in the city of Atlanta, and in the upper 50s for the north Georgia mountain towns.

That is according to 11Alive meteorologist Allison Chinchar.

"The Atlanta record for Sunday night/Monday morning is 63 degrees," Chinchar said Friday.

Temperatures will get even colder in parts of the upper Midwest and northern plains states.

Cities such as Minneapolis, Duluth, Bismark and Green Bay will see lows in the low to mid 40s Saturday night. Other cities such as Chicago, Des Moines and St. Louis will be flirting with record lows Saturday night as well.

It is not out of the question that some rural communities in Minnesota and North Dakota could see lows fall below 40 degrees -- in July!

Atlanta Weather | Friday Forecast

Partly cloudy skies today with just an isolated chance for rain in the second half of the day. Afternoon high temperatures will be in the upper 80s to low 90s.

Tonight mostly cloudy skies with overnight low temperatures around 70 degrees.

Heavy showers and a few thunderstorms return Saturday, otherwise mostly cloudy skies. High temperatures will be slightly cooler in the mid 80s. 

The second half of the weekend has just an isolated storm chance, along with high temperatures in the mid 80s.

Crazy Cold Air for July Coming Down the Pike!!!

Crazy Cold Air for July Coming Down the Pike!!!

As we all know we have had a very cool and wet summer! Not only has it been wet and cool here, but it has been wet and cool across the heartland as well. It is this persistent pattern we call the NW flow, and again all that means is that we get the jet stream from the north cutting towards the SE and that brings disturbances in one after the other. Those disturbances cool the air, and fire off new storms that get pushed by the NW jet stream flow. It is totally a self feeding mechanism that is almost impossible to break so just like I said in last night's blog I think this might continue for a while, possibly into the fall / winter.
