837 FXUS64 KEWX 071107 AFDEWX Area Forecast Discussion National Weather Service Austin/San Antonio TX 507 AM CST Sun Dec 7 2025 ...New 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... (12Z TAFS) Issued at 453 AM CST Sun Dec 7 2025 IFR to LIFR ceilings and some reductions in visibility continue this morning for locations mainly east of the I-35 corridor. For the areas farther to the north and west, conditions are VFR under mostly clear skies. Flight conditions improve by or through the mid-morning hours. Otherwise, a front will be advancing southward through the region from this morning into the afternoon. It will be possible that a patch of some post-frontal low to mid-level clouds advance through northeastern portions of the region, including the Austin metro area. Otherwise, gusty northerly winds will establish behind the front with peak gusts into the 25 kt range. Winds subside after sunset into Monday morning with skies trending mostly clear. && .PRELIMINARY POINT TEMPS/POPS...
