.DISCUSSION...
Issued at 1255 PM CDT Fri Jul 18 2025

Mid-upper inverted trof/disturbance situated over east/southeast Tx
should further weaken and lift nnw out of the vicinity tonight &
Saturday. Ridging should then gradually build in from the east as we
go through the weekend and into at least the middle parts of next
week. Increasing subsidence and lower PW`s with time will limit, or
eliminate, rain chances...and more sunshine will allow for a bump in
daytime highs.

Heading into the second part of next week, guidance is depicting
another inverted trof making its way wwd across FL, under the ridge
and toward the western Gulf Coast around Friday. (Looks like a
similar setup as to what we saw this week). If nothing else, it
should bring some increasing clouds/moisture and associated rain
chances back into the area. Some guidance tries to eventually
develop a weak surface circulation, but as of now, moderate winds
aloft could be a limiting factor for development. 47

Showers and storms will diminish this evening as light and
variable winds set in overnight. Isolated CIGS and patchy fog will
be possible during the early morning hours, which may bring some
FL reductions, mainly to MVFR levels, though these conditions will
likely be short lived. Isolated showers and storms will be
possible again Saturday afternoon, though mainly in areas around
and northeast of Houston.
