Area Forecast Discussion National Weather Service Austin/San Antonio TX 556 PM CST Fri Dec 6 2019
AVIATION. VFR through the period for all TAF site locations. IR satellite shows some high clouds streaming E/SE across the state and this will continue as broad W/NW upper flow persists in the mid to upper levels. Northerly surface winds at all sites tonight will be below 10 kt. The surface ridge will shift east tomorrow, and at some point in the afternoon the ridge axis should be east of AUS/SSF/SAT which should veer the winds to NE, then E/SE winds by late afternoon. This will happen out west at DRT a bit earlier in the AM hours. Speeds on Saturday should remain at or below 10 kt. Looking further ahead to Saturday night and early Sunday, model guidance is trending toward some MVFR as moisture return increases with stronger and deeper southerly winds. Will likely have to mention at least a SCT of strato cu Sunday AM in later TAF issuances.
PREV DISCUSSION. /ISSUED 241 PM CST Fri Dec 6 2019/
SHORT TERM (Tonight through Saturday Night) . Clear skies and breezy northerly winds are prevailing across South- Central Texas behind the overnight cold front. Temperatures range from the middle 60s in the Hill Country to the middle 70s for much of the rest of the area. The dry weather is expected to continue through the short-term with mostly clear skies continuing. Overnight lows will range from the middle 30s in the Hill Country to the middle to upper 40s for the rest of the area. Surface winds will begin to shift back to the south tomorrow as the surface high slides to the east. Highs will remain pleasant, in the middle 60s to lower 70s. With the south winds increasing by Saturday night, lows will be 3-5 degrees warmer than tonight.
LONG TERM (Sunday through Friday) . Southerly flow will continue on Sunday with winds at 850 mb out of the southwest. This should allow highs to get into the middle to upper 70s. The next upper trough will pass through the Plains on Monday which will send the next cold front into the area Monday evening. The timing should allow for some compressional warming ahead of the front Monday afternoon for our area. Should see some highs back in the 80s across much of the area. Temperatures will cool by Monday night as the front makes it through the area.
Models are in better agreement of the southern part of the trough axis hanging back and moving across Texas on Tuesday behind the cold front. This will setup good overrunning conditions with deep lift ontop of the frontal layer. This should bring a good coverage of light rain to the area late Monday night into Tuesday. Will increase PoPs into the 30-60 percent range, but these may need to be increased further if trends continue. With strong cold-air advection, and light rain, temperatures Tuesday will likely struggle to reach the upper 50s for most locations. Models are in good agreement that things will shut off pretty quickly by Tuesday night as drier air and subsidence moves into the region. Highs Wednesday will likely remain in the upper 50s to lower 60s. The next shortwave arrives to the area Thursday night and models are in better agreement with not a lot of QPF due to a lack of deep moisture return by the time the upper lift arrives. Will keep PoPs capped at 30 percent for now on Thursday and Friday.

Ad by Google
I do not sell or share any user data or anything else for that matter. I do not keep site logs longer than I need to to keep bad actors off the site. Basically, I delete them after looking at them. If you are subject to CCPA, Google ads on this site will not be based on your past behavior so you will likely not see an ad for a lawn mower just because you looked for one at a big box website. I do not believe this site is subject to CCPA but I am doing what I can to follow the guidelines anyway.
The information on this web site has not been checked for accuracy. It is for entertainment purposes only and should be independently verified before using for any other reason. There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
