.DISCUSSION...
Issued at 1018 PM CDT Sun Sep 28 2025
A generally pleasant forecast is expected for Deep South Texas and
the Rio Grande Valley. Rain chances remain low (under 30%) for the
duration of the forecast period. However this does not mean that a
rogue shower or two could not develop during the afternoon hours
with the seabreeze. The dry and subsidence from a mid-level ridge
and surface high pressure will continue to be the main influence for
the region thus why the rain chances are so low for the forecast
period.
While the high temperatures will remain slightly above normal, the
heat indices are not expected to be too high due to the amount of
dry air in the region. This will also mean that for the majority of
the forecast period that the Heat Risk will be minor (level 1 of 4).
The low temperatures are expected to remain about normal through the
period.
