Updated at 1036 PM CST Mon Nov 10 2025 -Low temperatures tonight will fall into the upper 30s across portions of the ranchlands with mid to upper 40s in the RGV. -Breezy, warm, and dry conditions are expected Wednesday into Sunday, with well above normal temperatures. && .DISCUSSION... Issued at 1036 PM CST Mon Nov 10 2025 A deep 500mb trough across the Great Lakes and eastern CONUS gradually swings into New England into the weekend, allowing high pressure to build across Deep South Texas. Low pressure drops down the Pacific coast and rolls northeast into the Southern Plains by Sunday night. At the surface, southerly winds return Tuesday, and generally persist into Sunday as the pressure gradient strengthens into the weekend. This will gradually build moisture, calming fire weather concerns, but not bumping rain chances above 10 percent. The next cold front arrives Sunday, also likely dry, with very limited impacts or change into early next week. Expect a chilly night tonight, below normal temps Tuesday into early Wednesday, then well above normal highs and lows return to Deep South Texas through Sunday afternoon. Forecast highs for BRO and MFE may approach record highs Saturday and Sunday. Temperatures behind the next front drop from well above normal to just above normal into early next week. While dry air remains in place across the brush country, winds remain a little light for a Fire Danger Statement at this time on Tuesday. Will continue to monitor model trends into Tuesday morning. Life-threatening rip currents briefly return Wednesday and again over the weekend. && .AVIATION...
