Lots of changes are in store for Acadiana over the next week with a series of disturbances likely to bring showers and some thunderstorms for mid-week followed by the coldest air of the season for Friday. A 
weak disturbance will pass through the area by late tomorrow perhaps bringing a few isolated showers in the western portions of Acadiana by late tomorrow afternoon. A stronger disturbance should bring a better chance of scattered showers and storms tomorrow night into Wednesday while another could bring rain and storms to the area again on Thursday accompanying a polar front that will get here for Thursday night. Quantitative precipitation forecasts are indicating that the heaviest rains this week will be in Texas, but rain totals this week could be in the inch range.Â
The coolest weather of the season should be here by Friday with highs hard-pressed to make 70 degrees Friday afternoon. Look for overnight lows to drop into the lower 50s through Saturday morning, but don’t get too used to the cool air as the front is expected to move back to the north rapidly this weekend. Strong warm fronts in El Nino years can sometimes bring severe weather, so be on the lookout this weekend, especially Sunday. We may even see a few strong storms before the front gets here midweek so we’ll be watching for that as well. Finally, another strong disturbance coming for the south and west could ignite intense storms by next Monday, so it appears that our weather will begin to get “El Nino-dynamic†as we head into mid-late October.
