190 FXUS64 KBRO 150520 AFDBRO Area Forecast Discussion National Weather Service Brownsville TX 1220 AM CDT Wed Oct 15 2025 ...New AVIATION... .KEY MESSAGES... Updated at 1220 AM CDT Wed Oct 15 2025 - Life-threatening rip currents are expected this weekend into next week along the beaches of the lower Texas coast. - Temperatures warm above normal by Friday to record or near record warmth Sunday into Tuesday. && .DISCUSSION... Issued at 1030 PM CDT Tue Oct 14 2025 A strong 500mb low along the West Coast swings into the Northern Plains by late this week, nudging the ridge across Texas out into the northern Gulf. This leaves weaker mid-level pressure across Deep South Texas with limited moisture. POPs drop below 10 percent Wednesday through Saturday. A surface low develops across the Southern Plains over the weekend and drops into East Texas by Sunday, dragging a cold front southward, likely stalling north of Deep South Texas. POPs have trended further down, now just briefly above 15 percent. The subtropical ridge returns into early next week, maintaining dry and warm weather. Expect seasonal temperatures gradually warming to a couple of degrees above normal Friday, and then adding a couple more degrees on Saturday, bringing a moderate (level 2 of 4) Heat Risk back to Deep South Texas and near triple digit heat across the brush country and upper valley. The heat persists Sunday into Tuesday, with potential record high temperatures across the RGV. Life-threatening rip currents are expected to increase this weekend into early next week. && .AVIATION...
