Wednesday Atlanta Weather Outlook

We hit 90 degrees for our high temperature Tuesday.  That's only the 3rd time we've hit 90 during the month of July.  The air was dry with low dewpoints and low relative humidity.  That's ending.  The humidity is coming back.  Moisture returns to make it feel more muggy and to give us a better chance for rain.

A few showers will redevelop Wednesday with temps holding in the mid 80s.  The rain chance sticks with us through early on Thursday.  Then we will have some dry days again Friday and Saturday, with moisture returning again at the beginning of next week.

Rain in ATL Because of Clean Air Act?

Rain in ATL Because of Clean Air Act?

Feel like you are living in Seattle or the Amazon Rainforest lately thanks to the non-stop rain? You can thank the Clean Air Act for that...well, sort of.

Back in 1970 the Clean Air Act was passed. This initiative focused on reducing airborne pollutants that posed a threat to human health. Jeremy Diem, a climatologist at Georgia State University performed research looking at 18 National Weather Service co-op weather stations and noticed that Atlanta’s average annual rainfall increased by 10 percent in the decade following the new Clean Air Act. He studied specifically the summer months during the years of 1948 to 2009.

Atlanta Weather | Monday Night Forecast

Mostly cloudy skies becoming partly cloudy skies through the evening. Light winds from the northwest around 5-10mph. Overnight low temperatures will be near record lows. Forecast is for 64° in the metro area, and 61° is the record for Tuesday morning.

Another pleasant day Tuesday with partly cloudy skies, lower humidities, and near normal high temperatures in the upper 80s.

The next big rainmaker returns Wednesday and lasts into Thursday. Temperatures will fall back slightly into the mid 80s both days.

Tropical Storm Flossie moving toward Hawaii

Tropical Flossie is moving closer to Hawaii.  It will move over the islands Monday with tropical storm force winds.  The islands are bracing for those strong winds and heavy rain to persist during the day Monday.  (The latest advisory from the Central Pacific  Hurricane Center is below)

The Pacific Hurricanes have a totally different list of names than the hurricanes in the Atlantic basin.  This is the sixth named storm in the Pacific so far this year.  The Atlantic has had 4 named storms so far.  That might clear up any confusion as to why we were just talking about Dorian in the Atlantic, and now Flossie in the Pacific.  Some folks have asked what happened to the "E" named storm.  We haven't had an "E" named storm in the Atlantic yet.  When we do, it will be Erin.  The "E" name in the Pacific was Erick.

Atlanta Weather | Dorian Bares Watching
 The remains of Tropical Storm Dorian will be passing just north of Puerto Rico today. Satellite images show no signs of a surface circulation, and just a moderate area of heavy thunderstorms associated with the storm. Air Force hurricane hunter aircraft are on call to investigate Dorian's remains on Monday afternoon, if necessary. Currently, the National Hurricane Center has given Dorian's remains a 50% chance of regenerating by Tuesday or Wednesday. Meanwhile, a rare occurrence in the Central Pacific Ocean.

Monday Atlanta Weather Outlook

Only a couple of isolated showers popped up Sunday afternoon.  They were moving slowly over to the east and diminishing.  Our high in Atlanta today was 86 degrees.

We will really have a better feel to the air Monday with that drier air in place.  It won't feel as muggy on Monday and Tuesday with the lower relative humidity.  Temps will hold in the mid to upper 80s.  

The rain chances return on Wednesday and Thursday.  Then the 90s return Friday and Saturday.

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.
