8/26/2020 The 7 day forecast is taking about 5 seconds to load but it will eventually load. NOAA is still working on it. 8/18/2020 NOAA continues to have trouble. Wind guest will occasionally be left off graphs. I am working with NOAA to resolve the issue. 12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed. 10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. |

Area Forecast Discussion National Weather Service Austin/San Antonio TX 1223 AM CDT Sun Sep 27 2020
AVIATION. Patchy MVFR ceilings starting to build in over the I-35 corridor and currently impacting AUS. Amending AUS to a bkn 1500ft for this and may need to amend SAT in the next hour or two. Ceilings are expected to further lower to IFR early this morning. Some areas of dense fog have developed the last two night but winds are stronger out of the south tonight than previous nights so expect less coverage of patchy fog and for this reason have not included mention in this TAF package. Tomorrow, ceilings scatter out late morning and southerly winds pick up as sfc pressure gradient across the state tightens. A strong front looks to push through just at the end of this TAF period and have only indicate the wind shift for AUS at this time.
PREV DISCUSSION . /ISSUED 106 PM CDT Sat Sep 26 2020/
SHORT TERM (Tonight through Sunday Night) .
The morning status clouds held on into the early afternoon hours with a decent coverage of clouds still in place across South-Central Texas. Should see plenty of breaks for the sun to warm up things into the upper 80s to lower 90s across the area today. For tonight, another return of clouds is expected, but forecast soundings favor just cloud cover over fog as the boundary layer is expected to remain somewhat mixed. Lows tonight will stay warmer than the past several nights, generally in the lower 70s across the region.
The dry weather should continue into Sunday as breezy conditions commence ahead of a changing weather pattern. A deep trough is expected to be pushing into the Central Plains tomorrow with a surface low deepening over Northwest Texas. This should allow southerly winds tomorrow to be in the 10-15 mph range with gusts up to 25 mph expected. This system will send in a cold front into the area after midnight Sunday night. Breezy northerly flow, cooler temperatures, and a slight chance of a shower will accompany the front as it makes it just east of the I35 corridor around sunrise Monday.
LONG TERM (Monday through Saturday) .
An active Monday is in store as a highly amplified upper air pattern will bring the aforementioned strong fall cold front through the area to begin the long term period. The remainder of the week looks quiet and rather nice.
Models are in surprisingly good agreement that at 12Z Monday the front will be draped across the region, with the current forecast depicting it's location from approximately Eagle Pass to just south of San Antonio to Giddings. Thus, some locations may see their high for the day just after midnight. Daytime temperatures look to max out in the 70s and lower 80s. Although a few models do keep portions of the Hill Country in the 60s through the day, thinking that sunshine should be able to prevent that.
Ample dry air aloft will keep precipitation chances nil across the majority of the region, however a few showers and perhaps a thunderstorm will be possible mainly east of I-35/I-37. Could also see some isolated showers develop along our southern tier of counties as well, though lower chances exist there. Any activity will more than likely end prior to 18Z.
The more impactful weather on Monday will be the post-frontal northerly winds, likely to top out in the 20-30 mph range with gusts potentially as high as 40 mph. A Wind Advisory may be needed. in terms of fire weather concerns, RH values will bottom out in the mid 20s in the northwest portions of our area in the afternoon, and the highest winds/gusts should be in the morning in that region. A Red Flag warning is unlikely, but conditions will still be near- critical. Winds will quickly diminish through the evening hours. Tuesday through Thursday RH will drop into the teens across the west half of the CWA, but winds aren't expected to be much of an issue, relaxing to near or below 10mph.
High pressure will then take over for much of the week with a gradual warming trend bringing highs back into the 80s and low 90s Wednesday and Thursday. A second, weaker cold front will push across the region in the Thursday-Thursday night timeframe as an even stronger high builds from the Canadian Prairies into the Plains. The upper air pattern is showing no signs of de-amplification prior to next weekend.
