.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.
