063 FXUS64 KEWX 090606 AFDEWX Area Forecast Discussion National Weather Service Austin/San Antonio TX 1206 AM CST Tue Dec 9 2025 ...New SHORT TERM, LONG TERM, AVIATION... .KEY MESSAGES... - Well above normal highs midweek, slight cooldown after a frontal passage sometime Saturday into Sunday. - Dry weather continues with no rain chances through at least Sunday. && .SHORT TERM... (Today through Wednesday) Issued at 1201 AM CST Tue Dec 9 2025 By sunrise early this morning we could see a few spots flirt with the freezing mark as strong radiational cooling happens overnight. As such we have decided to issue an SPS for this possibility for the overnight period. We should warm up nicely and by midday Tuesday surface winds return to a more southwesterly direction allowing for a boost to temps back above normal with many areas in the mid to upper 60s possibly approaching 70 in a few spots. As the high pressure moves off to the east models have been hinting at a surface boundary washing out across our area by early to midday Wednesday. As such lows overnight into Wednesday will remain mild with many areas remaining in the low to mid 40s. Additionally, high temps have been dialed back as this boundary causes a shift in winds back to the north northwest. Expect high temps to top out in the low to mid 70s in the east where the boundary will wash out with mid to upper 70s across the west. && .LONG TERM... (Wednesday night through Monday) Issued at 1201 AM CST Tue Dec 9 2025 As we move into the long term expect a slightly cooler night for Wednesday evening as northerly winds continue to allow for some advective cooling overnight. However, we arent looking at any freeze possibility as moisture will actually be on the increase heading into Thursday morning thus limiting that potential. Expect much more milder temps to continue for Thursday albeit it a touch cooler due to the slight delay in southerly flow. Low level southerly flow returns and really ramps up allowing highs to soar into the upper 70s to near 80 by Friday and possibly into Saturday as well. Lows during this period will also be much more mild with many areas staying in the upper 40s to mid 50s. Our next front then approaches sometime around late Saturday as the front looks to come in much slower now as previously thought. It still looks to remain rain free like the front that moved through this past Sunday and brings with it a slightly cooler airmass to the area for Sunday. The latest runs of the NBM continue to show considerable uncertainty regarding the timing and strength of this front. Regardless, expect very mild and dry weather through Sunday. Temps behind this front also look to drop back down to more seasonable levels with highs returning to the low 60s. Beyond Sunday, model ensembles are hinting at the possibility of some rain chances however this is still very far away and things could change. && .AVIATION... (06Z TAFS) Issued at 1201 AM CST Tue Dec 9 2025 VFR flight conditions continue through the period under mostly to completely clear skies. Winds remain light at 10 kt or less with speeds becoming south-southwesterly from the afternoon through Tuesday night. For KDRT, the winds remain more east to east- southeasterly in direction. && .PRELIMINARY POINT TEMPS/POPS...
