044 FXUS64 KEWX 070621 AFDEWX Area Forecast Discussion National Weather Service Austin/San Antonio TX 1221 AM CST Sun Dec 7 2025 ...New SHORT TERM, LONG TERM, AVIATION... .KEY MESSAGES... - Patchy to areas of fog mainly to the east of the I-35 corridor this morning - Dry cold front passages expected today and again towards early Friday with warmer air ahead of the fronts, and cooler air in wake of the fronts && .SHORT TERM... (Today through Monday) Issued at 1202 AM CST Sun Dec 7 2025 Patchy to areas of fog, possibly becoming locally dense, will be possible into this morning for areas primarily to the east of the I-35 corridor, where calm winds and higher dewpoints reside. Mostly clear skies will continue elsewhere. Expect winds to really ramp up by midday as a front progresses through our area from north to south. This front will help to clear out the fog in the Coastal Plains as well as help to limit high temps to the mid to upper 60s for those north of the front. Those further south can expect another mild day with highs topping out in the low to upper 70s. Expect winds to relax as mixing decreases and winds decouple towards evening and temps to plummet with many areas in the Hill Country dropping into the 30s with those across the I-35 Corridor and Coastal Plains and areas south dipping into the low 40s. By Monday We continue to see some weak CAA preventing temps from rising much and staying in the low 60s for areas east of I-10 and mid to upper 60s west. && .LONG TERM... (Monday night through Saturday) Issued at 1202 AM CST Sun Dec 7 2025 For the long term, expect advective cooling continuing into Monday night with north winds followed by radiational cooling heading into Tuesday morning given clear skies and light winds. This will make temperatures pretty chilly around sunrise, where some rural locations may near the freezing mark. However, it looks to be quite limited and for most, locations that have already experienced a light freeze this season. Elsewhere, mid 30s to low 40s can be expected. By Tuesday surface winds return to a more southerly 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. By Wednesday and Thursday low level southerly flow really ramps up allowing highs to soar into the upper 70s to near 80 Wednesday and into the low 80s by Thursday. Lows during this period will also be much more mild with many areas staying in the low 50s. Our next front then approaches sometime around Friday morning. It looks to remain rain free like the front moving through this Sunday and brings a slightly cooler airmass to the area into the start of the next weekend. && .AVIATION... (06Z TAFS) Issued at 1202 AM CST Sun Dec 7 2025 VFR flight conditions begin the period but expect for low clouds and fog to establish for mainly portions of the I-35 corridor and points east. Anticipate for MVFR to LIFR flight conditions to become possible across these areas, while VFR conditions continue elsewhere. A cold front arrives from the morning into the early afternoon and will clear out the fog and low clouds. A small area of post-frontal low to mid-level cloud cover could occur across north-northeastern portions of the area. Breezy north winds establish behind the front with gusts up to around 25 kts. Winds then gradually subside after sunset into Monday morning. && .PRELIMINARY POINT TEMPS/POPS...
