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

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

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. 

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.
