.DISCUSSION...
Issued at 1130 AM CST Mon Nov 3 2025

A rain-free forecast is expected for the duration of this forecast
period for Deep South Texas and the Rio Grande Valley. While
temperatures are expected to be close to normal for today and
tomorrow. Once the winds shift back towards the southeast, warm air
advection will occur over the region. This will in turn cause the
high temperatures to increase over the region by the mid week to the
upper 80s and lower 90s. By the end of the week, the high
temperatures for most of the region is expected to be in the low to
mid 90s.

Near the end of the forecast period, there are some models that
bring a frontal boundary close to the area and some models have to
front move through the area and bring some slightly cooler
temperatures. However, given the timing of the front and the
uncertainty in the forecast at this point, it will be best to keep
hopes of lower temperatures in check for the time being. Further
forecast shifts will have to keep track of the trends for the
forecast and see how this frontal boundary situation changes.
