Issued at 1255 PM CDT Fri Jul 18 2025 - Rain chances diminish and temperatures increase this weekend into the middle parts of next week. - The next decent chances of precipitation re-enter the forecast late next week. && .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 && .AVIATION... (00Z TAF Issuance) Issued at 548 PM CDT Fri Jul 18 2025 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. 03 && .MARINE... Issued at 1255 PM CDT Fri Jul 18 2025 As high pressure builds back into the region, expect light onshore winds and low seas to prevail through the weekend and into next week. 47 && .PRELIMINARY POINT TEMPS/POPS...
