Overnight temperatures dropped more quickly than we expected for many neighborhoods, causing the air temps and dew points to pair-up right after midnight. Remember, when the air temp and dew point are the same, the air is saturated. Add in little or no wind and you get pockets of dense fog that some of you had to deal with during the morning drive.
Dew points continued to fall through the day, so that even with Wednesday afternoon highs reaching the upper 80°s to low 90°s for most communities, it felt pretty good outside through the afternoon. And the air will continue to “dry” (falling dew points) into the evening and overnight. That should allow lows to drop into the low to mid 60°s around metro Baton Rouge on Thursday morning, with some WAFB communities along and north of the LA/MS state line possibly recording some upper 50°s. Yep -- feeling a little fall-like!
We could see a patch or two of fog for Thursday morning, but we are not expecting anything like what some of you saw early Wednesday.
The weather stays fair and dry into the weekend, with highs for Thursday through Sunday running near 90° or so each day. Thursday should be another beauty. By Friday afternoon, the winds will have swung around, coming out of the east and southeast. That will mean a return of low-level Gulf moisture (increasing humidity), but not enough to become uncomfortable nor to fuel afternoon showers. So you can plan on a good looking Friday evening for high school football, “Live After Five” in downtown BR, or for a trip to Gonzales to see the evening balloon-glow and lift-off at the Balloon Fest at the Lamar-Dixon Center.
Saturday stays dry too, although by Saturday afternoon we’ll have a near summer-feel to the air with dew points closer to 70° and highs at or above 90°.
Our rain forecast for Sunday also continues to decline: the latest extended guidance suggests that our next cool front will be slower to arrive than we previously thought. In addition, the latest guidance suggests that next week’s front -- now scheduled for arrival on a Monday/Tuesday time frame -- may not be as energetic as originally thought. So for now, we’ll back down rain chances from “likely” to “scattered” with the approach and passage of the of the system early next week.
All quiet in the tropics ... in fact, there is hardly really only one notable tropical wave evident on the satellite loops. Given that this is September, the peak month for tropical activity, it is all but “dead” right now across the Atlantic Basin -- and no one is complaining!
