(Today through Thursday night) Issued at 1132 AM CST Tue Dec 30 2025 The High pressure system associated with the cold and dry Canadian air mass centered over northeast Texas will continue to build and slide into the forecast area through tonight and Wednesday. This will allow for clear skies and mainly light winds that will set the stage for a very chilly night into early Wednesday morning. A light freeze along with areas of frost are likely for a majority of the forecast area with exception right along the coast. With very light to calm winds, wind chills will be close to actual air temperatures and therefore no cold weather advisory will be needed. The high pressure system will move off to the east during New Year's Eve night that will allow for light southerly winds to return and with that a moderation and warming in temperatures to begin the new year. 07/Rua && .LONG TERM... (Friday through Tuesday) Issued at 1132 AM CST Tue Dec 30 2025 Long term looks like a warm period again with above normal temperatures to start off 2026. Some southern stream energy coming from the east Pac will help develop a surface low and weak Pacific front across the Southern Plains into Texas on Friday. 35 to 40 knot low level jet at 85H developing that should make for a breezy day. However, overall moisture return is more of a modified Gulf variety so not that impressive. Therefore, with not impressive moisture amounts and weak low level convergence and upper level dynamics, not expecting a lot of shower activity as this Pacific front moves through late Friday and Friday night. Drier and seasonable conditions behind the Pacific front over the weekend, then another warm up early next week as high pressure moves off the east and low pressure develops over the Plains to provide a fresh southerly flow from the Gulf over the region. 07/Rua && .AVIATION... (18Z TAFS) Issued at 1132 AM CST Tue Dec 30 2025 High pressure at the surface and dry northerly flow aloft will combine for rather benign aviation conditions. Mainly clear skies expected with VFR conditions during the period. 07/Rua && .MARINE... Issued at 1132 AM CST Tue Dec 30 2025 Elevated offshore winds and seas will continue to gradually decrease into Wednesday as high pressure settles over the region. Onshore winds are expected by Thursday, then increasing and become gusty on Friday as high pressure moves off to the east and low pressure develops over the Southern Plains. Light offshore winds will then return over the weekend as the low pressure system moves off to the east. && .FIRE WEATHER... Issued at 1132 AM CST Tue Dec 30 2025 High pressure will settle over the region through Wednesday with dry conditions and mainly light northerly winds. Afternoon minimum relative humidity values will range between 30 and 40 percent. Cold temperatures are expected tonight with a light freeze and frost expected for a majority of the area. High pressure will move off to the east by Thursday with south winds returning along with an increase in low level moisture. && .PRELIMINARY POINT TEMPS/POPS...
