After another typical summer day for Acadiana Friday with a few isolated thundershowers possible, look for a better chance of scattered showers and storms developing deeper into this weekend.
A frontal system will drop to the Gulf Coast States early next week and likely stall across the region keeping higher than normal rain chances in the forecast for much of next week, while temperatures will likely drop below normal for the same period.
In the near term, expect another partly cloudy, hot and humid day Friday with highs in the lower 90s accompanied by a few widely scattered showers and/or a storm (at 20-30%), primarily from late morning through the mid-afternoon.
Higher atmospheric moisture levels will be advancing into the region from the east this weekend, translating to a gradual increase in the risk of showers and storms.
Rain chances Saturday will increase to near 40% late in the day into the early evening, while Sunday it becomes a 50/50 proposition, or better, at just about any time of the day, but especially for the afternoon.
As mentioned earlier, a frontal boundary will advance toward the region early next week but then become nearly stationary mid-late next week.
This feature will likely keep rain chances and cloudiness above normal for much of the week, with the risk of a few inches of rain on a few days, especially between Tuesday and Thursday.
Temperatures will respond to the cloud cover and rain chances by dropping to below normal, especially with regards to daytime highs.
Highs next week will be closer to the more air conditioner friendly mid-80s, while night time lows dip closer to the lower 70s.
Most importantly, it appears that surface pressures should remain high through next week (GFS & EURO agree), keeping the risk of tropical development very low.
