DISCUSSION

Issued at 1249 PM CDT Fri Sep 25 2026

The front that has been in our area for a couple days is dissolving as we speak and we'll see a gradual return to southeasterly flow this afternoon into tonight. Low temperatures tonight will hang on how quickly moisture comes back in. Think most areas north of the metro will cool similar to this morning with lows falling into the upper 60s. Closer to the coast will remain in the 70s and could see some slight warming late in the night from the southeast winds.

Generally quiet conditions are expected through the weekend though humidity will be on the rise with dewpoints back into the 70s for most of the area by late Saturday. An isolated shower is not out of the question along the coast over the weekend, but this will be limited and mainly in the morning hours.

Things get more interesting...and difficult to forecast...next week as the the strong mid level ridge we've been dealing with moves out of the region. The features we've been watching - Hurricane Polo and a mid-level ridge are starting to look like they will not phase correctly to bring the bulk of the moisture this far south as the hurricane now moves north on the front side of the trough instead of timing with the base of it. This interaction also will likely keep the trough from digging as far south as it could have and is looking more and more likely to not push a cold front all the way through the area. That said, we should still see an increase in rain chances next week, especially Wednesday to Thursday as gulf moisture increases and the sea breeze boundary should become more active. With more clouds expected, we would also see at least some improvement in temperatures toward normal, but time will tell if we can actually reach that or if we stay a bit above.
