864 FXUS64 KEWX 140428 AFDEWX Area Forecast Discussion National Weather Service Austin/San Antonio TX 1028 PM CST Wed Nov 13 2024 ...New AVIATION... .SHORT TERM... (Tonight through Thursday night) Issued at 226 PM CST Wed Nov 13 2024 A weak cold front will continue to push south and east through the the Coastal Plains early this afternoon. Slightly drier air and breezy northwesterly flow can be expected through early evening before winds subside somewhat overnight. The main difference we`ll notice will be cooler mornings, both Thursday and Friday, with temperatures in the 40s and lower 50s. Otherwise, it`ll remain mostly status quo with high temperatures, but perhaps just 5-10 degrees cooler Thursday. An even bigger cooldown looks to arrive around this time next week, but for more on that, have a look at the long term discussion. && .LONG TERM... (Friday through Wednesday) Issued at 226 PM CST Wed Nov 13 2024 At the start of the long term period, an upper level ridge will extend from the Gulf to the upper Mississippi River valley and a trough will be moving through the west coast states. The flow over Texas will be from the southwest. High pressure at the surface will be centered over the central Mississippi valley and the low level flow will be from the east to southeast across our CWA. This pattern will shift slowly to the east over the weekend turning the low level flow to the southeast. Subsident flow will keep the weather dry Friday and Saturday. Winds from the Gulf will moisten the boundary layer with dewpoints rising into the 60s by Sunday. A Pacific cold front will move through west Texas during the day Sunday. There may be sufficient lift as this front approaches to generate showers Sunday afternoon, but any activity will be isolated. The upper trough will lift northeastward from west Texas to Oklahoma Monday and Tuesday and push the frontal boundary through our CWA. This bring better chances for rain to South-Central Texas. Rain chances will move off to the east Monday night. Cooler and drier air will move in behind the front starting Monday night. The cooler air will be more evident in the morning with low temperatures around 10 degrees cooler Tuesday morning with highs Tuesday afternoon within a couple of degrees of Monday`s highs. Cooler air will continue to filter in Tuesday and Wednesday morning will be another 5-7 degrees cooler while afternoon highs will be around ten degrees lower than Tuesday. && .AVIATION...

Modest northerly winds prevail tonight with the I-35 terminals shifting slightly more northeasterly with time into and through Thursday afternoon.
