Above-map shows estimated rainfall next 3 days, more dry than wet for Metro Atlanta as for the most part our long dry spell continues:

The extreme heat is expected to at least “back down” some this weekend before coming back somewhat next week. Plenty more 90+ days to come before September is done!

But looking longer term, in 10-15 days or so, there are signs of an actual jet stream pattern change that may last a while as we replace mid and upper-level high pressure heat ridge with a trough and more of a Northwest to Southeast air flow bringing a change of air mass with it:

JET STREAM NOW:

JET STREAM LATE MONTH:

AIR MASS CHANGE AS ABOVE-NORMAL SHIFTS WEST WITH THE MID AND UPPER LEVEL RIDGE:

So if the global equations are right we will shift from our current East and Southern heat ridge to a ridge West and trough East pattern by the end of the month allowing a NW to SE jet stream pattern to bring in temperatures back down to normal or maybe even a little below average as we wind up September and go into October.

There are signals that the Month of October should average closer to normal so extreme heat should be gone by then even if we get some warm spells.

Unless we get hit by a tropical system the next 2-5 weeks rainfall looks below-normal on average despite a few scattered showers and storms the next 3-7 days, more dry than wet.
