With any luck, this will be the last summer-like weekend for Acadiana for quite a while...and if we are lucky, not until next May or June of 2020.
The strong and anomalous ridge of high pressure that has been so dominant on our hot pattern into this early fall period will begin to break down later this weekend opening the door for our first cool front of the fall season to arrive Monday.
Look for mostly sunny skies Saturday with hot afternoon temperatures reaching the low to mid 90s while heat indices approach 100 for perhaps the last day this year.
There will be the risk of scattered mainly late afternoon and/or early evening showers and storms for our Saturday, with rain chances near 30%.
Slightly drier air (courtesy of northerly winds) should move into the area Sunday as daytime temperatures will still climb into the lower 90s, but heat indices should be closer to the mid-90s.
There will be a slight chance of an afternoon shower or storm Sunday, but rain chances look to be closer to 20%.
Acadiana's first cool front of the season will arrive Monday with a fairly good chance of scattered showers and possibly a thunderstorm or two. Rain chances Monday will be in the 60% range for a few brief hours with highs holding closer to the mid-80s.
Tuesday and Wednesday should be nice and pleasant days with fair to partly cloudy skies, low humidity, and breezy conditions mainly on Tuesday, with highs closer to the low-mid 80s.
More importantly overnight lows should drop into the mid-60s for a couple of nights mid-week...and may be perhaps a little cooler especially across the northern parishes of Acadiana.
Temperatures will moderate quickly by Thursday ahead of what looks to be a stronger front arriving Friday (accompanied by a chance of scattered showers and thunderstorms).
This will leave next weekend feeling more fall-like, especially if clouds stick around Saturday.
Daytime highs next weekend may stay in the mid-70s while overnight lows could drop into the mid-upper 50...but this part of the 10 day forecast, is always subject to change!
The tropics continue to quiet down with no major suspect areas anticipated in our part of the world through next week...the weak area of low pressure near the Yucatan Peninsula has little or no future at this time due to hostile upper winds.
No resting easy until the month ends, but tropical meteorologists are cautiously breathing a sigh of relief at this point...and we all hope it stays that way for a few weeks more.
